Abstract

An asymmetrical structure for an open wrench is disclosed. The force-applying surface of the wrench facing the opening is mainly set as an arc surface, and the force-receiving surface of the wrench facing the opening is set as a flat surface. When a nut is engaged in the opening of the wrench, one side of the nut abuts against the force-receiving surface, and the other side is in contact with the force-applying point on the arc surface of the force-applying surface. When the wrench is turned, the force of the torque can only be transmitted through the force point contacting the nut, thereby preventing the force of the torque from being dispersed.

Description

technical field [0001] The invention relates to the technical field of open-end wrenches in hand tools, in particular to an asymmetric structure of an open-end wrench. Background technique [0002] see figure 1 , in the current technical field of wrenches, the most common one is this kind of metric open-ended wrench. One end of this kind of open-ended wrench has a working head, and the working head is provided with an opening, which is used to be sleeved on the nut, and Allowing the user to move the handle, the opening fixes the nut, and the length of the handle is the arm of force. When the user moves the handle and applies a force to it, the opening of the wrench has an impact on the nut. The applied force is: force × moment arm. [0003] figure 1 It is a partial enlarged side view of the opening 10 of a general open-end wrench. The opening 10 is mainly divided into a force application surface 11 and a force reception surface 12 facing and parallel to each other, and tw...
