Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention allows the handle to be slid to any desired position and held at any desired position.
The invention also relates to a telescoping handle device for a hand tool that allows work to be carried out in that state.

[Conventional technology]

Conventionally, many handle extensions and contractions such as spinner type ratchet trenches simply have a handle cylinder fitted onto the handle so that they can slide freely, and since the handle cylinder spins idly, it is possible to spin drive (shaft rotation) even when the bolt load is weak. I couldn't get it to rotate quickly.

[The problem that the idea aims to solve]

The present invention solves these drawbacks, and allows the protruding length of the handle tube to be easily and freely adjusted, and also allows the handle tube to be held at any position, and in that state can be rotated rapidly by spin drive. It is a technical problem to provide a telescoping handle device for a hand tool.

[Means to solve the problem]

A handle rod 2 with a circular cross section connected to the working part 1 is provided with flat sliding surfaces 2b at two opposing locations on the portion excluding the rear end 2a, and the handle rod 2 is shaped with a circular cross section so as to be in an overlapping state. A flat handle tube 3 is slidably fitted onto the handle tube 3, and the tip of the handle tube 3 is flattened at two places corresponding to the sliding surface 2b of the handle rod 2 to prevent the handle from coming off. A cylindrical portion 3a is formed integrally and continuously at the tip of the handle tube 3, and the rear end 2 of the handle rod 2
A pressure member 4 is pressed against the inner surface of the handle cylinder 3.
This invention relates to a telescoping handle device for a hand tool, which is characterized by being provided with a.

[Effect]

By holding the working part 1 in one hand and the handle tube 3 in the other hand, and pulling both, the handle rod 2 can be stretched to any length, and no matter where you release your hand, it will not touch the flat tube 3a. Since the sliding surface 2b of the handle rod 2 is fitted in a non-rotating state and there is no wobbling, rapid rotation operation by spin drive is possible as is, and when torque is applied, the working part 1 as shown in Fig. 1, for example. flex and perform normal tightening by ratcheting action.

〔Example〕

The drawing illustrates a spinner type ratchet trench.

This sliding surface 2b may be cut by machining, or may be formed by forging.

The flat cylindrical portion 3a is preferably formed by press working.

A spring 6 is housed in the hole 5 of the elastic member 4, and a ball 7 is supported by the spring 6.

It is preferable to use a pipe as the handle tube 3.

In the figure, 8 is a notch that facilitates pressing, and 9 is a stopper part.

[Effect of idea]

Since the present invention is configured as described above, it has the following features.

1. By pulling out the handle tube 3, the length of the handle rod 2 can be adjusted as desired.

2 In this case, at the tip of the handle tube 3, the flat tube section 3a and the sliding surface 2b overlap, and at the rear end, the inner surface of the handle tube 3 and the end 2a overlap. Since the inner surface of the handle tube 3 is elastically supported by the elastic member 4 provided at the end portion 2a, the handle rod 2 is stopped or fixed at the pulled out position.

3. Of course, in this handle cylinder 3, the flat cylinder part 3a and the sliding surface 2b overlap in a non-rotating fitted state, and the handle cylinder 3 is always integrated with the handle rod 2, so that high torque tightening is possible.

4. The formation of the flat cylinder part 3a is easy to manufacture since it is only necessary to press it into a flat shape, and it also serves to prevent the upper handle cylinder 3 from coming off.

5. Since the structure is simple, it is easy to manufacture, and the product can be provided at a lower price.

6 As mentioned above, when the bolts and nuts are loose, you can use the spin drive to quickly turn them, and when the bolts and nuts become loose, you can bend the handle as shown in Figure 1 and pull the handle out longer to ensure further tightening to the final tightening stage. It becomes a spinner type ratchet trench.
