Double-knob adjustable wrench adjusting method for rapidly adjusting opening amount

Abstract

Provided is a double-knob adjustable wrench adjusting method for rapidly adjusting the opening amount. A fixed wrench lip, a movable wrench lip and a handle are included. A circular shaft hole is formed in the upper portion of the fixed wrench lip, and the movable wrench lip is movably installed in the circular shaft hole. A front knob is installed at the front end of the handle, and a rear knob is installed at the tail end of the handle. The front knob and the rear knob are linked through a rotatable transmission shaft arranged in the handle, the front knob is connected with the movable wrench lip through a transmission part arranged in the fixed wrench lip, and the movable wrench lip can be driven to move in the circular shaft hole by screwing the front knob or the rear knob so as to adjust the size of the wrench opening. Rapid clamping can be achieved in two modes, and the clamping speed and the loosening speed are greatly increased when the size of the wrench opening is adjusted. The method can be used for occasions where the opening is inconvenient to adjust in a narrow space, the operation is convenient, time and labor are saved, the requirement for the use space is lowered, time is saved, and the working efficiency is improved.

Description

Technical field: [0001] The invention relates to the technical field of manual hardware tools, in particular to an adjustable wrench adjustment method for quickly adjusting the opening amount with double knobs. Background technique: [0002] Adjustable wrench is a manual bolt and nut fastening tool. It is labor-saving and fast during use. It has the characteristics of simple structure, convenient operation and strong practicability. It is currently a widely used wrench. It is widely used in engineering construction, equipment maintenance, installation, etc. Field workers can use adjustable wrenches. [0003] The structure of an ordinary adjustable wrench is mainly composed of a flat wrench lip, an adjustable wrench lip, a worm gear, a pivot pin and a handle. Turning the worm wheel of the adjustable wrench can adjust the size of the wrench. In the process of using ordinary adjustable wrench to fasten bolts and nuts, the following problems will be encountered: First, when bol...
