Abstract

The invention discloses an adjustable wrench. Six circle center pointed through holes are uniformly distributed in the side wall of a base (7), screw rods (3) and moving blocks (5) for butting bolt heads are mounted on the outer side and the inner side of the through holes, the moving blocks (5) are provided with internal threads matched with the screw rods (3), and the screw rods (3) are providedwith bevel gears I (10). The upper surface of the base (7) is provided with a circular groove (11), a driving wheel (8) is mounted on the base (7), the lower end face of the driving wheel (8) is provided with a convex ring matched with the circular groove (11), the outer side of the convex ring is provided with bevel gears II matched with the bevel gears I (10), and the upper end face of the driving wheel (8) is provided with a rotary driving projection (12). The adjustable wrench has advantages that a wrenching torque of a fixed wrench can be achieved, one adjustable wrench is capable of replacing fixed wrenches in multiple specifications, and accordingly weight and complicity of tools in vehicles are reduced, and purchase cost of enterprises is reduced.

Description

technical field [0001] The invention relates to an adjustable wrench, which belongs to the field of maintenance tools. Background technique [0002] With the increase of the number of automobiles in our country, the workload of automobile maintenance is also increasing. As we all know, every car will be equipped with on-board tools when it leaves the factory, and the wrench is one of the most important on-board tools. Different types of fixed end wrenches or sockets, which leads to the weight and complexity of the vehicle tool. [0003] That is: now there is a need for an adjustable wrench that can reach the tightening torque of a fixed wrench, and a single wrench can replace fixed wrenches of various specifications, thereby reducing the weight and complexity of the on-board tools, and at the same time reducing the cost for the enterprise. purchase cost. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an adjus...
