Hand tool improvement

This creation is about the improvement of the handle of a hand tool, especially the hand tool which is simple in setting, easy to assemble and use, convenient and convenient, can make the operation of the hand tool easier and more comfortable, and can improve work efficiency.

According to the conventional setting of electric or pneumatic hand tools (such as waxing machine, grinding machine, electric drill, etc.) with handles, as shown in the first figure, mainly on one side of the hand tool body 10 There is a pivot joint 101, and a handle 20 is fixedly mounted on the pivot joint 101. The pivot joint 101 can be a nut body. The handle 20 is screwed to the pivot body 101. According to the handle 20, the handle 20 is The hand tool body 10 is attached in a fixed and fixed manner, and when the hand tool is operated, the user can hold the force on the body grip 102 with one hand, and the other hand can hold the force on the handle 20, picking up the hand. The tool achieves the desired results. It is undeniable that it is an embodiment in which the handle 20 is attached to the hand tool body 10 in a fixed manner, which can actually make the hand tool work, but in the implementation of the implementation, there are the following shortcomings:

1. When the working angle corresponding to the hand tool is in a non-fixed or non-single form (such as when the waxing machine or the grinder is working, it will often be constructed along various surfaces or curved surfaces), due to the handle 20 The hand tool body 10 is fixed at a fixed angle, so that the hand holding the handle 20 must force the wrist to rotate according to the working angle at any time, thereby not only easily causing the handle to be gripped. 20 hands produce fatigue, soreness, and even accumulate the shortcomings of occupational diseases.

2. As mentioned in the preceding paragraph, since the hand holding the handle 20 is prone to fatigue, the work efficiency of the hand tool is inevitably greatly reduced, and the work efficiency is reduced.

3. As mentioned in the preceding paragraph, since the hand holding the handle 20 must constantly rotate the wrist in accordance with the working angle, the comfort and the smoothness of the hand grip are directly affected, and accordingly, the working angle varies greatly. In the occasion, the disadvantages of insufficient applicability of hand tools and limited use of the hand tools often occur.

The main purpose of this creation is to provide a hand tool improvement that can improve the above-mentioned deficiencies and to make the handling of the hand tool smoother and safer, and to make the grip of the handle more comfortable, and Effectively improve the efficiency of hand tools.

In order to achieve the above object, the present invention is provided with a linkage device between the hand tool body and the handle, the linkage device can implement multi-angle adjustment, and the handle can be coupled to the hand tool body at various angles, and the linkage device is provided with the first The connecting member, the supporting member, the second connecting member and the positioning member; wherein, by the swing adjustment of the first connecting member, the angle at which the handle is fixedly applied to the hand tool body can be changed, and the rotation of the second connecting member can be performed. The handle automatically matches the working angle of the hand tool. According to this, the operation of the hand tool not only has the comfortable grip and the smooth application and safety effect, but also achieves the purpose and effect of improving work efficiency.
