Description

U-shaped ratchet wheel steel wire rope reinforcing and disassembling tool Technical Field The invention relates to the technical field of mechanical manual tools, in particular to a u-shaped ratchet wheel steel wire rope reinforcing and dismounting tool. Background In modern military railway transportation, the steel wire rope fastening device, in particular to a U-shaped ratchet wheel steel wire rope fastener, is widely applied to the rapid construction and retraction of a temporary stay wire system due to the characteristics of reliable self-locking and convenient adjustment. The system is a key link in tasks such as railway transportation robbery, equipment reinforcement, emergency obstacle removal and the like, and the operation efficiency of the system is directly related to battlefield maneuvering speed and survivability of the army. However, in current modes of operation, completing a complete wire rope tightening or removal operation typically requires the operator to operate a variety of tools in sequence, including at least a wrench for preliminary pretensioning, a force bar for overcoming significant tension in the final tightening or removal, and a breaker for cutting the wire rope in an emergency. This decentralized, single-function tool configuration exposes significant tactical flaws under severe field conditions. Disclosure of Invention The u-shaped ratchet steel wire rope reinforcing and dismounting tool comprises a shell, wherein a worm is rotationally arranged in the shell, one end of the worm is provided with a driving assembly, the worm is meshed with a worm wheel rotationally arranged in the shell, a worm wheel shaft is fixedly arranged at the center of the worm wheel, the worm wheel shaft is rotationally arranged on the shell, a driving ring is fixedly arranged at one end of the worm wheel shaft, a fixed column is eccentrically and fixedly arranged on the driving ring, the fixed column is slidingly arranged in an annular groove, the annular groove is arranged on a movable cutter, the movable cutter is rotationally arranged on a fixed cutter through a cutter shaft, and the fixed cutter is fixedly arranged on one side of the shell.
