Novel wrench

Abstract

The invention discloses a novel wrench. The novel wrench comprises a handle and a U-shaped connecting piece fixedly connected with one end of the handle. A positioning locking block is hinged to an opening of the U-shaped connecting piece, a matched positioning rod penetrating through the positioning locking block and capable of sliding up and down on the positioning locking block is arranged at the top end of the positioning locking block, a wrench head clamping block is fixedly connected with the bottom end of the matched positioning rod, and a sleeve wrench head is detachably connected withthe end, away from the matched positioning rod, of the wrench head clamping block. According to different structural positions of bolts and nuts on a mechanical part, the distance between the positioning locking block and the wrench head clamping block can be adjusted by adjusting the matched positioning rod through the positioning locking block, so that the overall height of the wrench is adjustable, on the one hand, the bolts and the nuts of a common structure can be disassembled, and on the other hand, the bolts and the nuts of the difficult-disassembled structure installed in the equipment can further be screwed down and unscrewed; and the operability and practicability of the wrench are greatly enhanced, the structure is simple, and disassembly is convenient.

Description

technical field [0001] The invention relates to the field of wrenches, in particular to a novel wrench. Background technique [0002] A wrench is a tool that uses the principle of leverage to fasten or remove nuts and bolts. It is mainly used to disassemble mechanical parts. When using a wrench to disassemble mechanical parts, sometimes different structural positions are encountered on the same mechanical part. bolts and nuts, and for this situation, the dismantling personnel have to prepare many wrenches with different structures to deal with it. For the bolts and nuts installed inside the shell, the shell must be removed before they can be tightened and tightened with a wrench. Unscrew, but this will bring a lot of inconvenience to the disassembly workers. Contents of the invention [0003] In order to solve the above-mentioned problems existing in the prior art, the object of the present invention is to provide a new type of wrench, which can tighten bolts and nuts tha...
