Internal and external hexagonal wrench

Abstract

The invention discloses an internal and external hexagonal wrench. The internal and external hexagonal wrench comprises a wrench bracket, wherein five slideable hexagonal internal and external wrenches of different sizes are arranged in hexagonal through holes of the wrench bracket, and a sleeve with a handle is fixedly arranged at the upper end of the wrench bracket; hexagonal through holes are formed in the middle of the internal and external wrenches, and the internal and external wrenches can sleeve together in a sliding mode from outside to inside in sequence according to the size dimension; the five internal and external wrenches are equipped with supporting plates at the upper end of a panel at one side, the top ends of the supporting plates are planes in the inclined direction, and are provided with certain horizontal planes, and the supporting plates are sequentially and continuously staggered in the same inclined plane direction; spring pressure plates with through holes are arranged on the outer side surfaces of the supporting plates; spring supporting rods are arranged on positions, which correspond to the upper surface of the wrench bracket, of the through holes; springs sleeve the spring supporting rods, and the springs are fixedly connected with the spring pressure plates and the wrench bracket; and in use, a suspension is selected in a rotary mode, and elasticity of springs is utilized for pressing, selecting and replacing internal and external hexagonal wrenches of different models. According to the internal and external hexagonal wrench disclosed by the invention, models are conveniently switched, so that operation is simple, and carrying is easy.

Description

technical field [0001] The invention relates to an improvement of a wrench, in particular to an internal and external hexagonal wrench with two functions. Background technique [0002] In the prior art, the integrated hexagonal wrench described in the application number 201210022613.6 includes a sleeve and a handle connected to the sleeve; the front section of the sleeve is provided with an inner groove, and outside the inner groove of the sleeve Wrench studs are connected, and the wrench studs include a plurality of different types of hexagonal studs, and the studs of multiple models are all hollow structures, and are sequentially connected on the same axis; the sleeve is provided with a plurality of different sizes. Columnar springs, each columnar spring corresponds to the corresponding column head; there are multiple L-shaped grooves on the circumferential surface of the sleeve, each groove is connected with a positioning pin, and is connected to a different columnar spri...

[0002] In the prior art, the integrated hexagonal wrench described in the application number 201210022613.6 includes a sleeve and a handle connected to the sleeve; the front section of the sleeve is provided with an inner groove, and outside the inner groove of the sleeve Wrench studs are connected, and the wrench studs include a plurality of different types of hexagonal studs, and the studs of multiple models are all hollow structures, and are sequentially connected on the same axis; the sleeve is provided with a plurality of different sizes. Columnar springs, each columnar spring corresponds to the corresponding column head; there are multiple L-shaped grooves on the circumferential surface of the sleeve, each groove is connected with a positioning pin, and is connected to a different columnar spring The bottom end can effectively reduce the number of hexagonal wrenches and achieve multiple functions in one body, but only the inner hexagonal wrench is not integrated with the outer hexagonal wrench, which has great limitations in use
