Description

Wrench with stop effect

The present invention relates to a wrench, in particular a wrench that can be easily switched and has a blocking effect.

The existing wrench is used by the user to lock or loosen the locking pieces such as bolts or nuts. In the existing wrench, a clamping surface corresponding to the outline of the locking piece is generally formed through the inner side surface of the wrench head in the axial direction, and the locking piece is rotated by abutting against the clamping surface. Although the existing wrench can provide an effect of locking or loosening the locking piece, the wrench head of the existing wrench can only abut against the outer peripheral surface of the locking piece. Therefore, when the existing wrench cover is set During the rotation of the lock, the clamping surface of the wrench head may be misaligned with the outer peripheral surface of the lock, or the wrench head may pass through the lock during the installation process, so that the existing wrench cannot accurately abut against the lock to lock or loosen, and the wrench head needs to be repeatedly aligned with the lock to achieve the effect of rotating the lock. The wrench head cannot be stably positioned on the lock, which is relatively inconvenient and time-consuming to use.

In view of the above problems, when manufacturing existing wrenches on the market, a coupling groove is formed on the top surface of the wrench head, and a positioning plate is coupled in the coupling groove. The inner edge of the positioning plate extends out of the clamping surface, so that when the existing wrench is set on the locking piece, the bottom surface of the positioning plate will abut against the top surface of the locking piece, thereby providing an effect of stabilizing the wrench head and avoiding the wrench head from passing through the locking piece; however, although the above method of providing the positioning plate can allow the wrench head of the existing wrench to be stably positioned with the locking piece, it is necessary to process the coupling groove and add the positioning plate when manufacturing the existing wrench, and after manufacturing, the positioning plate needs to be fixed in the coupling groove to avoid the occurrence of The situation where the wrench head passes through the locking piece will not only increase the time and cost required for manufacturing, but also the positioning plate combined in the coupling groove will easily affect its structural strength due to structural damage or loosening after long-term use, resulting in the separation of the positioning plate and the wrench head, so that the existing wrench cannot have the effect of stabilizing the wrench head and preventing it from passing through the locking piece; further, since the positioning plate of the existing wrench is fixed on the wrench head, when the user does not need the positioning plate for positioning, the positioning plate cannot be adjusted or moved relative to the wrench head, which relatively limits the convenience and flexibility of the existing wrench; in summary, the existing wrench still needs to be improved.

Therefore, in view of the defects and shortcomings of existing wrenches in actual operation, the present invention has finally developed a wrench that can improve the existing defects after continuous testing and research.
