Embodiment Construction

[0011] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0012] figure 1 It is a structural schematic diagram of an embodiment of the present invention.

[0013] Such as figure 1 Shown: a new type of wrench, including a jaw 2 and a handle 1, the inner upper and lower layers of the jaw 2 are provided with an occlusal surface 3, the occlusal surface 3 is a serrated surface, and the upper layer of the serrated surface is in line with the The lower serrations mesh with each other. The serrated surface and the jaw 2 are integrally formed, and the material of the serrated surface is metal.

[0014] The present invention is simple in structure and easy to operate. By setting the occlusal layer 3 inside the jaw 2 of the wrench, the wrench can have a larger contact area between the bolt and the jaw 2 of the wrench when the wrench is pulling the bolt. Generate greater friction, prevent slippage, and ensu...

Abstract

The invention relates to a novel wrench. The novel wrench is characterized in that an upper layer and a lower layer inside a jaw opening are provided with the snapping faces which are sawtooth faces, and the sawtooth faces of the upper layer and the lower layer are meshed with each other. The novel wrench is simple in structure and convenient to operate. The snapping faces are arranged inside the jaw opening of the wrench, so that large friction force is produced between a bolt and the jaw opening of the wrench in the bolt pulling process of the wrench, a slipping phenomenon can be prevented, normal working can be further ensured, and the working efficiency and working convenience are greatly improved by adopting the novel wrench.

Description

technical field [0001] The invention relates to a wrench, in particular to a novel wrench for preventing slippage, and belongs to the technical field of metal fittings. Background technique [0002] Wrenches are widely used in our daily life and production. Traditional wrenches for screwing bolts include handles and jaws. The width of the jaws is consistent with the width of the bolts to be screwed. It is a metal part. Therefore, after the jaws of the wrench are placed on the bolts, there is still a certain gap between the jaws and the bolts. Therefore, when the wrench is rotated, due to the friction between the jaws and the bolts If it is not enough, it is easy to slip, so that the bolts cannot be screwed smoothly, which increases the difficulty of work. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a novel wrench with a simple structure and preventing slippage. [0004] To achie...
