Description

[Detailed description of the invention] [Field of industrial application] The present invention provides a clamping tool having a long handle that can grip an article at a remote location by hand operation, and particularly a gripping tool having the long handle. This invention relates to a separable clamping tool.

[Conventional technology]

For example, when grabbing an item that is out of reach, such as on a roof or on the surface of a pond, or when removing an item that is placed in a narrow space that cannot be accessed by humans, keep these items close at hand. A gripping tool is required that can be held at a distance from the object. As such a clamping tool, a clamping mechanism consisting of a pair of arms is provided at one end of a handle having a required length formed of a tubular body, and an operating mechanism is provided at the other end of the handle, and the operation of the operating mechanism is controlled. A structure is known in which the arm of the clamping mechanism is opened and closed to perform a clamping operation by transmitting the information to the clamping mechanism via a transmission member such as a rod inserted into the handle.

On the other hand, this type of clamping tool naturally has long dimensions due to the above-mentioned uses, which makes it inconvenient to store and carry when not in use, so there is a need to make the handle splittable in the middle. However, the conventional ones do not have a structure in which the handle can be separated because a transmission member such as a rod has to be inserted inside, which causes the above-mentioned inconvenience when storing. Ta.

By the way, according to Publication No. 60-10371,
A device related to high branch scissors having a long handle that can be divided is disclosed. This is used for collecting fruits such as apples and persimmons from branches at high places, and for pruning tree branches. With the operation lever at the end,
The cutting operation is performed via a rod inserted into the inside of the long handle, and the long handle and rod are detachably divided at the middle part. Therefore, the long handle and rod used in this high branch scissors are divided into detachable structures.
It is possible to apply it to the clamping tool used to grasp objects at a distant position as mentioned above, but the divided part of this high branch scissors can be used simultaneously when connecting and disconnecting the front and rear pipe bodies. Not only is it necessary to perform an extra operation to move the component of one of the female and male fittings used at the joint end of the internal rod back and forth in the axial direction using a pin protruding outside the tube body, but it is also necessary to Since members such as springs and balls are used inside the tube, which are difficult to adjust, reliable operation is difficult to achieve, and the overall weight is increased.

[Problem that the invention attempts to solve]

As mentioned above, in the past, there has been no gripping tool with a splittable handle that allows you to grip objects at a remote location by hand, making it inconvenient to store or carry. was coming. In addition, it is known that the handle is splittable for Takabashi scissors that have a structure similar to this type of clamping tool, but the structure of the split part of the handle in this Takabashi scissor requires a large number of parts and is difficult to operate. There are drawbacks such as a lack of certainty.

Therefore, the present invention is a clamping tool that can grip and hold objects at a remote location by hand operation. It is an object of the present invention to realize a clamping tool having a structure that can be reliably and easily attached and detached.

[Means to solve the problem]

The present invention is characterized in that it is constructed as follows in order to solve the above problems.

That is, by inserting a rod movably in the axial direction into a handle formed of a tubular body and constructing a clamping mechanism at each front end of the handle and rod, a fixed arm and a movable arm that can be opened and closed relative to the arm are formed. and a fixed rod and an operating rod constituting an operating mechanism are respectively connected to the rear ends of the handle and rod, respectively,
When the operating rod is operated in the closing direction against the urging force in the opening direction by a bullet interposed between it and the fixed rod, the operation is transmitted to the movable arm of the clamping mechanism via the rod. In a clamping tool having a long handle, the handle and the rod are divided into a front and a rear part at the middle part, and the other end is attached to one of the mutually opposing ends of the divided front part and rear part. A fitting portion to be fitted is provided, a guide groove is formed in the fitting portion to guide the pin fixedly planted on the circumferential surface of the other end from the axial direction to the circumferential direction, and A holding cylinder provided with a notch on the outside through which a pin inserted up to the circumferential tip of the guide groove intervenes in the axial direction is fitted so as to be movable back and forth.

On the other hand, the opposing ends of the two divided rods are restrained in the rotational direction with respect to the front and rear handles, and the fitting operation is caused by the relative movement of the two handles in the axial direction, and the subsequent relative rotation is performed. Connects a pair of male and female locking fittings that are fitted and locked to each other.

The above-mentioned fitting portion may be provided at either the rear end of the divided front rod or the front end of the rear handle, and similarly, the pair of male and female locking fittings may be provided at the rear end of the divided front rod or at the front end of the rear rod. A female or male metal fitting may be connected to either of the front ends of the rear rod.

[Effect]

According to the above configuration, when connecting the divided handles when using the clamping tool, the circumferential surface of the end of the other handle is inserted into the guide groove of the fitting part provided at the end of one handle. The ends of both handles are fitted together while introducing the pin fixed therein, and when they are fitted to a predetermined position, both handles are rotated relative to each other and the pin is introduced in the circumferential direction along the guide groove. . When the pin is introduced to the circumferential tip of the guide groove, the holding cylinder fitted to the outside of the fitting part so as to be freely retractable is advanced, and the pin is inserted into the notch provided in the holding cylinder. Intervene. As a result, the pin is fixed to the circumferential tip of the guide groove, and the relative rotation of the front and rear handles that are fitted together is restricted, ensuring that both handles are securely connected. will be done.

On the other hand, when the ends of both handles are moved relative to each other in the axial direction in order to fit them to a predetermined position during the connection operation of the handles as described above, the front and rear parts inserted into the insides of both handles respectively. The pair of male and female locking fittings provided at the end of the rod also move relative to each other in the axial direction, and the male fitting is inserted into the female fitting, and when the two handles are further rotated relative to each other, these two fittings move relative to each other in the axial direction. Since the locking metal fittings are restrained in the rotational direction with respect to the front handle and the rear handle, both metal fittings also rotate relative to each other and are locked with each other. This causes the front rod and the rear rod to be connected in a manner capable of transmitting axial motion.

In this state, if the operating rod of the operating mechanism at the rear end of the rear handle is operated against the force of the projectile, the operation will be carried out by the clamping force at the front end of the front handle via the rear rod and the front rod. The force is transmitted to the movable arm of the mechanism, and the movable arm is swung in the opening direction or the closing direction relative to the fixed arm, making it possible to clamp the article. If the movable arm swings in the closing direction relative to the fixed arm when the operating rod is operated against the force of the projectile, the article can be moved by the operating force applied to the operating rod. If the movable arm swings in the direction of opening relative to the fixed arm when the operating rod is operated against the force of the projectile, it is possible to When the operating force is released, the article will be gripped by the auxiliary force of the ammunition.
