Problems solved by technology

[0002] The wheel wrench is one of the necessary tools for the car. It is convenient for customers to replace the spare tire when the car tire is damaged. The current wheel wrench has a single specification and can only be equipped with the tire nut of the corresponding specification. Corresponding to one type of tire nut, it is impossible to achieve universality. Manufacturers must equip different wheel wrenches for different car tires, which makes the manufacturer's material management increasingly complicated, which is not conducive to the unified allocation of resources, and even causes waste of resources.

Abstract

The invention aims to provide a regulable wheel wrench which conveniently corresponds to various specifications of tyre nuts to enable the wheel wrench to be more universal. The wheel wrench comprisesa wrench body and a plurality of sliding blocks for clamping the nuts and is characterized by also comprising a regulating box fixed on the end part of the wrench body; a bottom cover of the regulating box is provided with radially arranged strip-shaped guiding holes which correspond to the sliding blocks one by one; the sliding blocks can be clamped in the guiding holes in a sliding mode; the middle of the regulating box is provided with a regulating shaft; the periphery of the regulating shaft is provided with regulating columns in directions towards the guiding holes; the regulating columns are connected with the sliding blocks by connecting rods for converting the rotation of the regulating shaft into the slide of the sliding blocks along the guiding holes; and the wrench also comprises a locking mechanism which can be used for locking or allowing the regulating shaft to rotate. The wrench has the advantages of simple structure and accurate and convenient regulation, can be used for operating various specifications of nuts and is more convenient to use.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing, in particular to a wheel wrench for automobiles. Background technique [0002] The wheel wrench is one of the necessary tools for the car. It is convenient for customers to replace the spare tire when the car tire is damaged. The current wheel wrench has a single specification and can only be equipped with the tire nut of the corresponding specification. The tire nut corresponding to one specification cannot achieve universality, and manufacturers must equip different wheel wrenches for different car tires, which makes the manufacturer's material management increasingly complicated, which is not conducive to the unified allocation of resources, and even causes waste of resources. Contents of the invention [0003] The purpose of the present invention is to provide an adjustable wheel wrench to facilitate the corresponding tire nuts of various specifications, making the wheel wr...
