Anti-following torque multiplying wrench

Abstract

The invention discloses an anti-following torque multiplying wrench, and belongs to the field of tools. The anti-following torque multiplying wrench comprises a torque multiplier and an anti-following mechanism mounted on the torque multiplier. A rocker is mounted on an input shaft of the torque multiplier, and a nut socket, which is an inner hexagonal socket or an outer hexagonal sleeve or a quincuncial socket, is mounted on an output shaft of the torque multiplier. A pair of lateral lugs is disposed on a sidewall of the torque multiplier. The anti-following torque multiplying wrench, which is hinged to the torque multiplier by means of the side lugs, comprises a connecting handle having one end hinged to the side lugs of the torque multiplier and the other end on which a limiting beam in a vertical direction is fixedly mounted. An anti-fooling wrench is fixedly mounted on a top end of the limiting beam. The anti-following torque multiplying wrench solves the problem of following that is common in the use of a bolt and a nut, and has the outstanding advantages of integrated structure convenient in use, large torque and the like.

Description

technical field [0001] The invention relates to the field of tools, in particular to an anti-coil rotation torque multiplier wrench, which is used for tightening or dismounting external hexagonal bolts or other similar structures fastened by external hexagonal nuts. Background technique [0002] Bolts and nuts are commonly used fasteners in daily life and production. They are widely used in various fields due to their simple manufacture and strong adaptability. However, when nuts and bolts are used to fasten workpieces, the phenomenon that the bolts rotate around the shaft often occurs, that is to say, the bolts will follow the rotation of the nuts. Especially after the bolts and nuts are rusted to death, the following phenomenon is particularly serious. [0003] In order to prevent the bolt from rotating, the measure most people take is to use the upper and lower wrenches to twist in opposite directions to tighten or disassemble it. Moreover, it is necessary to lubricate ...

Problems solved by technology

When dismantling or repairing these porcelain insulators, because the construction site is at a high altitude, improper operation when using two wrenches can easily cause falling objects, and the cutting tools cannot reach the high altitude, so it is extremely difficult to remove these rusted porcelain insulators
