Wrench for rusted bolt disassembling

Abstract

The invention discloses a wrench for rusted bolt disassembling. The wrench comprises a wrench handle body, a wrench fixing base, a handle sleeve, an adjusting worm gear, a fixed wrench lip, a movablewrench lip, an adjusting groove, a positioning hole, a telescopic adjusting part, multiple threaded through holes, a bolt assembly, the wrench fixing base, anti-slip tooth grooves, a clamping groove,a stepped screw hole, a magnet block, a pre-tightening screw, a limiting spring, a rectangular supporting block and a longitudinal threaded installing hole; the bottom end of the longitudinal threadedinstalling hole communicates with a transverse liquid flowing channel, an oblique liquid flowing channel is installed in the wrench fixing base, one end of the oblique liquid flowing channel communicates with the transverse liquid flowing channel, and the other end of the oblique liquid flowing channel communicates with a wrench opening; and an oil injector is installed in the longitudinal threaded installing hole, and cooling lubricating oil in the oil injector is injected into the oblique liquid flowing channel under the action of the oil injector. According to the wrench for rusted bolt disassembling, the structural design is novel, adjustment is convenient, time and labor are saved, the wrench can adapt to rusted bolt disassembling operation in a smaller space, mechanical equipment isnot damaged in the disassembling process, and disassembling is convenient.

Description

technical field [0001] The invention relates to the technical field of hardware appliances, in particular to a wrench for disassembling rusty bolts. Background technique [0002] A bolt is a kind of fastener consisting of a head and a screw rod. It needs to be matched with a nut to fasten and connect two parts with through holes. If the nut is unscrewed from the bolt, the two parts can be made The parts are separated, so the bolted connection is a detachable connection. [0003] Generally, ordinary wrenches can be used to disassemble the bolts, but the disassembly of rusty bolts is more troublesome. At present, the rusty bolts on mechanical equipment are generally disassembled in the following ways: [0004] 1. If the bolts are not very rusted, you can gently tap and twist them with a hammer until the bolts are removed, but this method is easy to damage the mechanical equipment due to hammering. [0005] 2. Apply some kerosene, gasoline or rust remover. After the oil has f...

Problems solved by technology

[0004] 1. If the bolts are not very rusted, you can use a hammer to gently tap and twist until the bolts are removed, but this method is easy to damage the mechanical equipment due to hammering

[0005] 2. Apply some kerosene, gasoline or rust remover. After the oil has fully penetrated the bolts, you can use a hammer to gently tap and twist until the bolts are removed. However, sometimes this method cannot effectively remove the bolts.
