Abstract

The invention discloses an adjustable wrench with a self-tightening function. The adjustable wrench comprises a main body block, a fixed clamping block, a movable clamping block, a movable plate, a rotating shaft, a connecting plate, a spring and a handle, wherein the handle is arranged at the lower end of the main body block, the fixed clamping block and the movable clamping block are arranged at the upper end of the main body block, the fixed clamping block is located on the left side of the movable clamping block, the right side of the fixed clamping block and the left side of the movable clamping block are clamping faces, the clamping face of the fixed clamping block and the clamping face of the movable clamping block are each provided with a mounting groove, the mounting grooves penetrate through the front end and the rear end of the fixed clamping block and the front end and the rear end of the movable clamping block, the movable plate is arranged in the mounting grooves, a through hole in the front-back direction is formed in the movable plate, the rotating shaft is inserted into the through hole, and a side hole is formed in the bottom side, close to the mounting grooves, of the through hole. According to the adjustable wrench, the movable plate, the rotating shaft and the spring are matched, so that the adjustable wrench can effectively clamp a clamped object in the using process, the clamped object is not prone to loosening and slipping, the good self-tightening effect is achieved, and the using effect of the adjustable wrench is guaranteed.

Description

【Technical field】 [0001] The present invention relates to the technical field of tools, especially the technical field of adjustable wrenches. 【Background technique】 [0002] The adjustable wrench is a commonly used tool, which is mainly used for the removal and installation of fasteners such as bolts and nuts.
