Tool occlusion

The present invention is a partial improvement of the tool for fastening or releasing the screw member like a sleeve or a wrench. In particular, the present invention is a tool nip that prevents the head of the screw lock from being worn.

Nowadays, a sleeve or a wrench having a hexagonal occlusal portion is commonly used in life, and the occlusal portion can be used to pull the screw lock member after the hexagonal head portion of the screw lock member is engaged, thereby effectively fastening or releasing the screw lock member. However, after a long time of pulling and applying the screw, the six end angles of the head of the screw lock are often worn, so that the inner end angle of the occlusion portion cannot effectively engage the six end angles of the head of the screw lock, resulting in The screw lock is difficult to tighten or loose.

In order to solve the above problem, there is a design in the market where the inner end corners of the nip portion are connected in an arc shape. Although the design avoids the wear of the end angle of the screw lock head, the nip portion of this type of tool is in contact with the screw lock head. The area is very limited and can be said to be just a point of contact. The occlusal portion cannot firmly contact the head of the screw lock, so the force can not be effectively transmitted to the screw lock member, and the accidental slippage and the failure to drive the screw lock member are often caused. In addition, there is no suitable occlusal design that can be effectively used for screw locks where the head of the screw lock has been severely worn.

Since the design of the tool occlusion portion has the aforementioned problem of the head of the wear screw lock member, and the effective application of the screw lock member that has been severely worn, how to effectively transmit the force and avoid the wear, it is now a design tool for the developer. The focus of the occlusion.
