Description

[Detailed description of the invention] This invention is a relatively small gardening tool that is used mainly for one-handed work, and the tool can be changed by simply turning the blade or other tool or its mounting seat at the tip of the handle. This device relates to a device for fixing a blade plate or other working tool or its mounting seat to a handle so that the type of the blade can be changed without any problem, the angle at which the blade is attached to the handle can be changed, or the neck can be folded when not in use.

For example, in the case of gardening tools such as weed cutting, root cutting, and weeding sickles, which are handled by holding the handle with one hand, one type of tool is attached to the end of the handle depending on the purpose, and it can be used for multiple purposes. I couldn't.

Therefore, it was necessary to prepare separate tools depending on the purpose.

Furthermore, using a sickle as an example, if you wanted to change the attachment angle of the blade to the handle depending on what you are reaping, conventionally you would have to prepare a sickle with a different blade angle.

The present invention was devised to eliminate these drawbacks, and includes a sheath body 2 that is biased forward with respect to the handle 1 by a spring 4 near the tip of the handle 1. For this purpose, a blade plate or other working tool or a mounting seat having multiple claws that can be fitted into the sheath body 2 is pivotally mounted, and depending on the application, the blade plate or other working tool or its mounting seat is rotated to an appropriate position. At this position, the claws provided thereon can be fitted into the sheath body 2 and fixed therein.

Embodiments of the present invention will be described based on the accompanying drawings.

A sheath body 2 is attached near the tip of the handle 1, and a coiled spring 4 is interposed between the projecting piece 2a of the sheath body 2 and a stopper 3 provided on the handle 1 behind it, so that the sheath body 2 The handle 1 is urged forward by a spring 4.

When the protruding piece 2a is hooked with a finger and the sheath body 2 is pulled backward, the sheath body 2 moves backward on the handle 1 against the elasticity of the spring 4.

At the tip of the handle 1, a mounting seat 5 for mounting a blade A and other working tools is pivotally mounted. There are two claws 5 on the mounting seat 5.
a, 5b are formed, and both claws 5a, 5b close the gap 7 formed between the handle 1 and the front inner surface of the sheath body 2.
Each piece is inserted into the hole.

The blade A mounted on the mounting seat 5 is formed with two blades a and a' as shown in FIGS. 1 and 2, for example.

Next, the operation in this case will be explained.

One of the two claws 5a and 5b provided on the mounting seat 5, for example 5a, is inside the sheath body 2 and is attached to the handle 1.
When inserted into the gap 7 between the two, rotation of the mounting seat 5 is prevented, and the blade plate A becomes approximately horizontal with respect to the handle 1, as shown in FIG. It can also be used as a soil remover, and when it is turned upside down in the state shown in FIG. 1, its blade a can be used, for example, as a sickle blade.

If you want to use it in other ways, do the following.

First, by placing a finger on the protruding piece 2a and pulling the sheath body 2 backward, the mounting seat 5 can be rotated about the pivot 6. For example, when the sheath body 2 is pulled rearward as shown by the chain line in FIG. When the sheath body 2 is rotated in the direction of the arrow in the figure and then released, the sheath body 2 moves forward on the handle 1 due to the elasticity of the spring 4, and the front edge of the sheath body 2 moves forward on the handle 1. Another claw 5b fitted into the gap 7 is clamped as shown in FIG. Therefore, rotation of the mounting seat 5 is prevented, and as shown in FIG. 2, the blade A is kept at an angle such that it bites into the handle 1, and the blade A' is used for cutting grass. be able to.

In these cases, if at least the tip of the sheath body 2 is tapered so that the tip is thicker and the rear part is thinner, the claw will sink firmly into the sheath body 2, and the blade plate by the sheath body 2 will The fixation of A or its mounting seat 5 becomes even stronger.

On the other hand, when not in use, the two claws 5a and 5b can be folded by bending the neck without fitting them into the sheath body 2, as shown in FIG.

The mounting seat 5 may be omitted, the blade plate A may be pivoted directly to the handle 1, and a plurality of claws may be directly attached to the blade plate A.

The number of claws is provided according to the number of blades provided on the blade plate A.

In the illustrated example, the blade plate A has two claws a.
Although the case where the blade plate can be used for multiple purposes by forming the blade and a′ is illustrated, the present invention can also be applied, for example, to the case where the attachment angle of the blade with respect to the handle 1 is desired to be sequentially different. can.

Further, the present invention can be widely applied to fixing work tools other than plate-shaped blades, such as rakes, fork-shaped tools, transplanting trowels, root cutters, etc.

According to the present invention, it is possible to easily change the mounting position of the blade or other work tool or its mounting seat relative to the handle 1 by performing a simple operation. For example, the mounting position of the work tool or its angle can be easily changed. This is extremely convenient when the type of work tool can be easily changed depending on the purpose. Also, after that change, pattern 1
On the other hand, the blades and other working tools or their mounting seats are firmly fixed and do not move unnecessarily, and do not cause any hindrance to gardening work. When not in use, it can be stored by bending the neck.

As shown in the example, if at least the tip of the sheath body 2 is tapered such that the tip is thicker and the rear part is thinner, the claws will firmly dig into the sheath body 2 and the sheath body 2 will The fixation of blade plates and other work tools or their mounting seats becomes even stronger.
