Detailed Description
A detailed description of a structural schematic of a forearm-rotation muscle strength enhancer according to the utility model is provided below with reference to examples. The following examples are only for more clearly illustrating the technical solution of the present utility model, and are not intended to limit the scope of the present utility model; various changes and modifications may be made by one of ordinary skill in the art without departing from the spirit and scope of the utility model, and all such equivalent technical aspects are intended to be within the scope of the utility model, which is defined by the following claims.
FIG. 1 is a schematic view showing the structure of an embodiment of the forearm rotation muscle strength enhancer of the utility model. The forearm rotation muscle strength enhancer comprises a first column body 1, a second column body 2 and a resistance shaft 5, wherein the resistance shaft 5 comprises a central tension spring 50 and a plurality of short tension springs 51; the first column body 1 and the second column body 2 are respectively provided with a containing tube 10 along the length direction, the containing tubes 10 extend to opposite ends of the first column body 1 and the second column body 2, and two ends of the center tension spring 50 respectively extend into and are fixedly connected with the containing tubes 10 of the first column body 1 and the containing tubes 10 of the second column body 2; the opposite ends of the first column 1 and the second column 2 are fixed with a plurality of pull rings 4 at positions avoiding the accommodating tube 10, and two ends of the short tension spring 51 are respectively fixed on the pull rings 4 of the first column 1 and the pull rings 4 of the second column 2.
The outer surfaces of the first column body 1 and the second column body 2 are wrapped with an anti-skid rubber sleeve 6.
The anti-slip rubber sleeve 6 is provided with an elastic band 60 along the length direction, and two ends of the elastic band 60 are fixed on the anti-slip rubber sleeve 6.
The anti-skid rubber sleeve 6 is provided with anti-skid patterns on the surface, wherein the anti-skid patterns can be any one of straight stripes, wavy stripes or rectangular distributed strip-shaped patterns, and the friction force between the palm and the rubber sleeve is increased through the anti-skid patterns.
