Problems solved by technology

Existing traditional hexagonal wrenches usually need to carry multiple types of wrenches to deal with hexagonal bolts of different sizes and models, and it is easy to lose too many wrenches at the same time. The inner hexagon bolts need to be replaced with different types of wrenches, and the efficiency is also greatly reduced

Abstract

The invention discloses an internal hexagonal wrench and relates to the technical field of dismounting tools. The internal hexagonal wrench comprises a rod body, a front end cover, a rear end cover and a handle, wherein the front end cover and the rear end cover are arranged at the front end and the rear end of the rod body respectively, the handle is mounted on the rod body, a hexagonal through hole is formed in the rod body in the axial direction of the rod body, a plurality of hexagonal sleeves are inserted in the hexagonal through hole at intervals, a center rod is inserted in the hexagonal sleeve on the innermost side in a clearance mode, the length of the center rod is the same as that of each hexagonal sleeve, a check block is arranged at the rear end of each hexagonal sleeve, an inlet and outlet hole is formed in the end of the front end cover, an opening adjusting device is arranged in the front end cover, and a push rod corresponding to each check block is arranged on the rear end cover, and a return pull rod connected with the central rod is arranged on the rear end cover. The internal hexagonal wrench is convenient to use and can cope with assembly and disassembly of internal hexagonal bolts of various sizes and models at the same time, the center rod and all the hexagonal sleeves can be retracted into the rod body after the internal hexagonal wrench is used, and the opening adjusting device can prevent the center rod and all the hexagonal sleeves from popping up accidentally.

Description

technical field [0001] The invention relates to the technical field of assembly and disassembly tools, in particular to an inner hexagonal wrench. Background technique [0002] In modern production operations, hexagon socket bolts have been widely used in various types of equipment. At this time, the corresponding hexagon socket wrench has become an indispensable tool for disassembly and assembly. Existing traditional hexagonal wrenches usually need to carry multiple types of wrenches to deal with hexagonal bolts of different sizes and models, and it is easy to lose too many wrenches at the same time. The inner hexagon bolts need to be replaced with different types of wrenches, and the efficiency is also greatly reduced. Contents of the invention [0003] The purpose of the present invention is to provide a hexagon socket wrench, which can handle hexagon socket bolts of different sizes and models, and is beneficial to improve disassembly and assembly efficiency. [0004]...
