Quick-moving movable spanner

Abstract

The invention discloses a quick-moving movable spanner. A spanner body is internally provided with a quick driving mechanism composed of an active driving mechanism and a driven transmission mechanism. The active driving mechanism consists of a spiral sliding rod (4), a driving bevel gear (5), an elastic ring (6), a button (7), a gasket and pin (8), wherein one end of the spiral sliding rod (4) is provided with the driving bevel gear (5), and the other end of the spiral sliding rod (4) is fixed; the elastic ring (6) sleeves the spiral sliding rod (4) to be prevented from moving; and the button (7) is inserted into a spiral groove of the spiral sliding rod (4) and is positioned through a gasket and pin(8). The driven transmission mechanism consists of a driven bevel gear (9), a worm (10), a spring (11), a pin (12) and a plug screw (13), wherein one end of the worm (10) is fixed on the wall of the spanner body (1) through the spring (11) and the pin (12), and the other end of the worm (10) is fixed on the driven bevel gear (9), and positioned in the spanner body through the plug screw (13); the active driving mechanism and the driven transmission mechanism are mutually associated with each other through the engagement of the driving bevel gear (5) and the driven bevel gear (9); and the worm is sprayed with antirust paint.

Description

technical field [0001] The invention relates to a wrench, in particular to an adjustable wrench whose jaws can be opened and closed quickly. Background technique [0002] Now using a common adjustable wrench, the opening and closing of the jaws is completely realized by constantly rubbing the worm thread with the thumb, which is laborious, time-consuming and low in work efficiency. Contents of the invention [0003] The purpose of the present invention is to provide users with a push-pull adjustable wrench that can quickly and effectively open and close the jaws in one operation. [0004] The invention consists of four parts: a wrench body, a movable jaw, a fast driving mechanism and a cover plate. [0005] The wrench body is an integral forging, the front end of the head is a fixed jaw, the side of the head and the side of the handle are provided with notches, which respectively accommodate the movable jaw and the quick drive mechanism. And there is a ring wrench hole a...
