Activity boarder

This creation is about a wrench, especially about a spanner wrench.

Today, most people choose cars as a means of transportation. Cars have become one of the most used vehicles in daily activities. However, when cars fail during driving, they are usually attached. As a standard, the bag hand tool can be used to lock or remove the screw to meet the basic rescue measures required.

In the existing work of locking or disassembling screws, the wrench tool is very important, but the wrench tool still has many inconveniences in use. For example, when the wrench tool engages a larger size screw, it is not easy to rotate, and even more The manipulator can remove the screw. Even if the wrench can rotate, it needs multiple turns to complete the function of locking or dismounting. Therefore, when the vehicle is faulty, such as disassembling the locking screw on the tire, it can be said that it is time-consuming. Quite laborious.
