What is a ratchet wrench?
A ratchet wrench is a manual screw-tightening tool with a double-head multi-standard movable handle (fixed hole). This wrench is connected by the main and slave plum sleeves with different specifications and sizes by engaging the female and male hinges. Because a plum sleeve has two specifications for a plum-shaped through hole, it can be used to tighten two types of screws, thereby expanding its scope of use and saving raw materials and labor costs. The movable trigger can easily adjust the angle of the wrench. This wrench is used to tighten screws and has the characteristics of strong applicability, convenient use, and low cost.
