new hex wrench

Abstract

The invention relates to hexagon wrenches, in particular to a novel hexagon wrench. According to the novel hexagon wrench, the manner that according to an original external hexagon wrench, torque force application is changed into lever force application is adopted, and meanwhile the non-return characteristics of a ratchet wheel and a structure that multiple external hexagon wrenches are nested together through threads are utilized, so that compared with the prior art, loose external hexagon bolts can be rapidly screwed down in the small and narrow space, and the problem that in the past, when the space is not enough, after the external hexagon wrenches are rotated by a certain distance, the external hexagon wrenches need to be relocated on the external hexagon bolts, and then rotation is carried out to carry out screwing down and screwing off is solved; and meanwhile, the external hexagon wrenches of different types are collected together, and therefore a user can conveniently carry and use the wrench.

Description

technical field [0001] The invention relates to a common tool, in particular to a hexagonal wrench. Background technique [0002] The hexagonal wrench is a commonly used hardware tool for tightening and dismounting the hexagonal bolts; at present, the hexagonal wrench is a curved rod with a regular hexagonal cross-section and bent into a right angle. The curved rod is divided into a long handle section and a short handle section. When tightening or removing the hexagon socket bolt, insert one end of the long or short handle section into the regular hexagonal groove of the hexagon socket head bolt head, and turn it through the short or long handle section several times until the bolt is completely tightened or removed . However, when there are many devices at the installation position of the hexagonal bolt and the space is narrow, the hexagonal wrench cannot perform circular motion, and can only adjust a small angle each time. After each adjustment, the hexagonal wrench must...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the deficiencies in the prior art, the present invention provides a new type of hexagonal wrench, which can quickly tighten and loosen the outer hexagonal bolts in a relatively narrow space, and solves the problem that the outer hexagonal wrench must be replaced outside when the space is insufficient in the past. Rotate the hexagonal bolts to tighten and loosen them. At the same time, several different types of external hexagonal wrenches are assembled together, which is convenient for users to carry and use.
