Ratchet wrench is a manual screw tightening tool, single-head, double-head multi-specification ratchet wrench (fixed hole). It is connected by the main plum blossom sleeve and the secondary plum blossom sleeve of different specifications and sizes through the female key and the male key of the hinged key.

Because a plum blossom sleeve has two specifications of plum blossom-shaped through holes, it can be used for tightening screws of two specifications, thereby expanding the scope of use and saving raw materials and labor costs. The movable trigger can easily adjust the use angle of the wrench. This kind of wrench is used for the tightening operation of the screw, and has the characteristics of strong applicability, convenient use and low cost.

A ratchet wrench belongs to the technical field of wrench tools. The ratchet wrench includes a wrench body, and a circlip, a pawl, a spring, and a ratchet wheel are arranged in the accommodating space of the head of the wrench body. The ratchet wheel is composed of a ratchet wheel body and a spacer. It is a circular ring with a concave ring groove on the periphery, and the spacer sleeve is sleeved on one side of the ratchet body.

The said ratchet wrench, by decomposing the ratchet component of the original integrated structure into a combination of the ratchet body and the spacer, avoids the processing difficulty caused by the concave ring groove on the original ratchet component with one high side and one low side. Since the ratchet body and the spacer components are relatively easy to process, the processing and production efficiency of the ratchet wrench is greatly improved, and the production cost is also reduced.
