Description

Technical Field

[0001] The utility model belongs to the technical field of wrenches, and in particular relates to a percussion open-end wrench. Background Art

[0002] The strike wrench is forged as a whole from 45# medium carbon steel or 40Cr steel. It is an important type of manual wrench. Generally, the hand-held end is the strike end and the front end is the working end. It mainly includes two types: the strike wrench and the strike wrench. However, the existing technology cannot store the wrench head well, which makes it easy for the wrench head to hit people, resulting in low safety performance.

[0003] Application number "CN201920765652.2" records "a percussion open-end wrench, comprising a working end, a force-applying handle, a percussion end, a traction ring, and a sealing member, wherein the force-applying handle is used to connect the working end and the percussion end, the traction ring is welded to the tail of the percussion end, the working end is provided with an opening for tightening a nut or a bolt, and the sealing member is welded to the opening of the working end."

[0004] The above patent is based on the percussion open-end wrench and improves the open-end percussion wrench. A traction ring is set at the rear end. During use, two people cooperate, one person pulls the rope through the traction ring, and the other person strikes with a hammer, avoiding the possibility of hurting fingers. A sealing part is welded on an arc surface at the working end. When the space around the nut is limited and a percussion wrench cannot be used, the percussion open-end wrench can be used. It occupies a small space and has strong applicability. It can also avoid the situation where the bayonet of the conventional percussion open-end wrench is disengaged from the nut during use, thereby improving work efficiency and avoiding possible injuries.

[0005] The above patent is provided with a traction ring. During use, two people cooperate with each other, one person pulls the rope through the traction ring, and the other person strikes the hammer with a hand, thereby avoiding the possibility of injuring fingers. A sealing piece is welded on an arc surface at the working end. When the space around the nut is limited and a striking ring wrench cannot be used, the striking open-end wrench can be used. It occupies a small space and has strong applicability. It can also avoid the situation where the bayonet of the conventional striking open-end wrench is disengaged from the nut during use, thereby improving work efficiency and avoiding possible injuries. However, the above device controls the wrench with a rope by providing a traction ring at the end of the wrench. However, during the operation of the striking wrench, the hand is generally away from the wrench, and the work is achieved by striking the end of the wrench. Therefore, the safety problem described in the above wrench is not prominent. The wrench head is arranged outside. If it accidentally hits someone, there is a safety hazard. Therefore, a striking wrench that can conveniently store the wrench head is needed. Utility Model Content
