Multifunctional wrench and assembling and using method thereof

Abstract

The invention provides a multifunctional wrench and an assembling and using method thereof, and belongs to the field of disassembling and assembling tools. The problems that existing wrenches are lowin operation efficiency and poor in flexibility are solved. The multifunctional wrench comprises a wrench handle of which the front end is provided with a wrench sleeve, and a wrench hole is formed inthe wrench sleeve; the multifunctional wrench further comprises a wrench head, the outer wall of the wrench head is provided with a limiting groove, and the groove wall of the limiting groove is provided with a positioning groove; the wrench head is arranged in the wrench hole; the wrench handle is provided with an adjusting hole, and an adjusting rod is arranged in the adjusting hole in a penetrating mode; the rear end hole wall of the adjusting hole and the rod wall of the adjusting rod are provided with a slide groove and a slide block correspondingly, and a compression spring is arrangedin the slide groove; and a rod groove is formed in the wrench handle. The multifunctional wrench further comprises an adjusting sleeve which sleeves the wrench handle, a connection rod, and a reset spring, wherein the wall of the adjusting rod is provided with a connection hole; one end of the connection rod is connected with the inner wall of the adjusting sleeve, and the other end of the connection rod is arranged in the connection hole in a penetrating mode; and the reset spring is located in the rod groove and sleeves the adjusting rod, and the two ends of the reset spring abut against thefront side wall of the rod groove and the connection rod. The wrench is higher in operation efficiency and flexibility.

Description

technical field [0001] The invention belongs to the technical field of assembly and disassembly tools, and relates to a multifunctional wrench and an assembly and use method thereof. Background technique [0002] Traditional bolts generally have an outer hexagonal or outer octagonal head, and are screwed with a corresponding wrench. There is an existing ratchet wrench that can effectively improve the efficiency of the wrench screwing bolts, but the structure of the ratchet wrench is complex, the cost is high, and the wrench head cannot be replaced, so it can only be adapted to the bolts of the corresponding specifications, and the flexibility is poor, so it is necessary to improve . Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems in the prior art, to provide a multi-function wrench and a multifunctional wrench which can be easily changed to adapt to various head shapes, has high operating efficiency, and is ...
