One-way ratchet wrench

Abstract

The invention provides a one-way ratchet wrench, and belongs to the technical field of wrenches. The wrench solves the problem that an existing wrench is low in assembling efficiency. The one-way ratchet wrench comprises a wrench body, a ratchet wheel, a tooth block, a spring, an ejection block and a pressing plate, a containing hole is formed in the head of the wrench body, the ratchet wheel is arranged in the containing hole, a containing groove communicating with the containing hole is formed in the upper surface or the lower surface of the head of the wrench body, and the tooth block and the ejection block are arranged at the two ends of the containing groove correspondingly; and the pressing plate is arranged in the containing groove and located above the ejection block and the pressing plate, the pressing plate is located on the wrench body, the pressing plate and the ejection block are integrally formed, the spring is arranged between the ejection block and the tooth block, andthe tooth block is meshed with the ratchet wheel and can be separated from the ratchet wheel. The structure obviously improves the assembly efficiency of the one-way ratchet wrench.

Description

technical field [0001] The invention belongs to the technical field of wrenches and relates to a one-way ratchet wrench. Background technique [0002] When the ordinary wrench is turning the screw, due to the influence of the position of the screw or nut, it may be interfered by other parts or objects after turning a certain angle, so that the wrench cannot continue to be turned. The wrench can only be pulled from the screw or nut first. Take off the upper handle, then adjust the angle and put the wrench on the screw or nut again, so that the screw or nut can be tightened or unscrewed repeatedly, especially in the case of a small rotatable angle, the efficiency is very slow, and the operation Very cumbersome. [0003] At present, the one-way ratchet wrench on the existing market greatly improves the convenience of screw or nut assembly and disassembly. , ratchet support teeth and magnetic matching block, one end of the plate body is provided with a head, and a insertion gr...

AI Technical Summary

Problems solved by technology

[0004] The alcove groove of the above-mentioned one-way ratchet wrench is set on the inner wall of the insertion groove, and only one end of the alcove groove facing the insertion groove is designed to be open. The blocks and springs are sequentially loaded into the groove of the recess through the insertion groove and the opening. Since the space of the insertion groove is very small, the ratchet teeth, magnetic matching blocks and springs are loaded into the groove of the recess. It has high difficulty and great inconvenience, which greatly affects the assembly efficiency of the one-way ratchet wrench; in addition, when machining the recess groove, it is necessary to open holes along the radial direction of the insertion groove on the inner wall of the insertion groove, because the insertion groove The space is very small, which also makes the processing of the alcove groove extremely difficult
