Abstract

The invention relates to a fast-adjusting monkey wrench, which comprises a wrench handle body and a shovel-shaped adjustable wrench head, wherein the front end of the wrench handle body is provided with a fixed wrench head with a hexagonal hole; a screw rod is arranged at the tail of the adjustable wrench head which can move back and forth in a cavity arranged in the front part of the wrench handle body; a front slotted hole, a medium slotted hole and a back slotted hole are arranged at the rear of the cavity in a ladder-shaped form and in longitudinal direction; a sleeve provided with internal threads is arranged in the front slotted hole; the sleeve is sheathed with the tail of the adjustable wrench head in a threading mode; and a handwheel variable regulating mechanism is positioned inside the medium slotted hole. The monkey wrench adopts the handwheel variable regulating mechanism to adjust the adjustable wrench head and has high operation efficiency. The monkey wrench can bear larger torque force but not slide or wear, thereby keeping good work performance for the monkey wrench and disassembled nuts.

Description

technical field [0001] The invention relates to hardware tools, in particular to a quick-adjust adjustable wrench. Background technique [0002] Adjustable wrench is a widely used hardware tool, and the adjustment speed of common adjustable wrench is slow, and the working efficiency is low. On the other hand, the meshing planes of the common adjustable wrench and the nut are two parallel planes, and the meshing surface of the adjustable wrench and the nut has only two surfaces, which will easily slip and wear due to excessive torque, and even bite the nut. If it is damaged, both the adjustable wrench and the disassembled nut will lose their working performance. Contents of the invention [0003] In order to overcome the disadvantages of the prior art, the object of the present invention is to provide a quick adjustable adjustable wrench, which adopts a handwheel variable speed adjustment mechanism to adjust the movable blade head, and has high working efficiency. The adj...
