Abstract

The invention discloses a caliber-adjustable wrench. The wrench comprises a rack, wrench clamping jaws, a round groove, a rotary ring, a plurality of push rods and an adjusting device, wherein the rack comprises a handle area and a wrench area; the wrench clamping jaws are distributed on one end face of the wrench area in an annular shape and can slide back and forth in the radial direction of the annular shape; the round groove is formed in the other end face of the wrench area, and a plurality of first sliding grooves protruding in the radial direction and corresponding to the wrench clamping jaws in a one-to-one mode are formed in the periphery of the round groove; the rotary ring is arranged in the round groove in a rotary mode, a plurality of second sliding grooves corresponding to the first sliding grooves are formed in the end face of the rotary ring, and the second sliding grooves are obliquely formed; one end of each push rod is located in the corresponding first sliding groove and is correspondingly connected with one wrench clamping jaw, and the other end of each push rod is located in the corresponding second sliding groove; the adjusting device is connected with the rotary ring to drive the rotary ring to rotate forwards or reversely. The wrench can overcome the defect that an existing special tool can not change in-pair wrench holes in different gaps.

Description

technical field [0001] The invention relates to wrench equipment, in particular to a wrench capable of adjusting the caliber. Background technique [0002] A wrench is a commonly used installation and removal tool. A hand tool that uses the principle of leverage to turn bolts, screws, nuts, and other threaded openings or sockets that hold bolts or nuts tightly; wrenches are usually made with a clamping handle at one or both ends of the handle, and an external force is applied to the handle. The bolts or nuts and the openings or sleeve holes of the bolts or nuts can be twisted; when in use, an external force is applied to the shank along the thread rotation direction, and the bolts or nuts can be twisted. [0003] In the field of industrial production, pairs of vertical holes are often used as wrench holes on some disassembled parts. The size and spacing of these wrench holes are usually different due to the differences in parts. Special tools are usually required for disass...
