Combined Allen Wrench

Abstract

The invention discloses a combined type internal hexagonal wrench. The combined type internal hexagonal wrench achieves the purpose that an electric wrench can conveniently disassemble / lock internalhexagonal bolts with different models, and can effectively solve the problem that an external square hexagonal prism or an internal square hexagonal prism cannot be used normally due to the fact thatside edges of the internal square hexagonal prism deform so that the internal square hexagonal prism cannot slide along a square hexagonal prism hole. The combined type internal hexagonal wrench comprises the external square hexagonal prism, the internal square hexagonal prism and a limiting structure, wherein the square hexagonal prism hole is formed in the first end of the external square hexagonal prism, a wrench inserted connection hole used for being matched with the electric wrench is formed in the second end of the external square hexagonal prism, the internal square hexagonal prism isslidably arranged in the square hexagonal prism hole, and side edge deformation reserved holding tanks are formed in the side edges of the internal square hexagonal prism correspondingly.

Description

technical field [0001] The invention relates to the field of electric wrenches, in particular to a combined hexagonal wrench. Background technique [0002] During the operation of the current electric wrench, for different types of hexagon socket bolts, it is necessary to replace the corresponding type of hexagon socket wrench, which not only makes the operation inconvenient, but also affects the working efficiency. [0003] For this reason, some inventors have designed a combined hexagon socket wrench, which combines regular hexagonal prisms of various sizes and models, and is provided with a regular hexagonal prism hole on the end face of the outer regular hexagonal prism. Prism, in this way, the regular hexagonal prisms of different sizes and models are nested together from the inside to the outside; although such a combined hexagonal wrench is convenient to use and can improve work efficiency; but it has the following disadvantages: [0004] Since there is inevitably a ...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a combined hexagonal wrench, which can not only facilitate the disassembly / locking of different types of hexagonal bolts by electric wrenches, but also can effectively improve the deformation of the side edges of the inner regular hexagonal prism, making the inner regular hexagonal prism Unable to slide along the hole of the regular hexagonal prism, resulting in the problem that the outer regular hexagonal prism or the inner regular hexagonal prism cannot be used normally
