The spring protection sleeve includes a spring protection inner sleeve and a spring protection outer sleeve, and the spring protection inner sleeve and the spring protection outer sleeve are sequentially arranged on the outer side of the spring.

The lengths of the spring protection inner sleeve and the spring protection outer sleeve are both shorter than the length of the spring.

Both the first connecting rod and the second connecting rod are curved.

Both the first connecting rod and the second connecting rod are bent inward, and the bending angle is greater than 90 degrees.

The two ends of the spring are respectively hinged to the first connecting rod and the second connecting rod through spring connecting pins.

The two ends of the spring are respectively hinged to the middle positions of the first connecting rod and the second connecting rod through spring connecting pins.

By adopting the utility model, during the body-building process, the handle is held with both hands, squeezed inwardly with force, repeated operations, and the arm strength is exercised.

The beneficial effects of the utility model are: simple structure, safe and reliable, good exercise effect and easy to carry.

Description of drawings

Fig. 1 is the structural representation of the utility model;

Among the figure: connecting rod connecting pin 1, connecting rod one 2, spring connecting pin 3, handle 4, spring protection inner sleeve 5, spring 6, spring protection overcoat 7, connecting rod two 8.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described by example.

A safe muscle training apparatus, comprising a connecting rod 2, a handle 4, a spring 6, a spring protection sleeve and a connecting rod 2 8, the connecting rod 2 and the connecting rod 8 are curved rod structures composed of straight rods and inclined rods, The bending angle between the straight rod and the diagonal rod is an obtuse angle; the diagonal rod ends of the connecting rod one 2 and the connecting rod two 8 are hinged by the connecting rod connecting pin 1, and the straight rod ends are all provided with handles 4; The straight rods of rod one 2 and connecting rod two 8 are hinged, and the straight rods of spring 6 and connecting rod one 2 and connecting rod two 8 are vertically arranged; the length and bending angle of connecting rod one 2 and connecting rod two 8 are the same, along the vertical The axis of the spring is arranged symmetrically; the outer side of the spring 6 is provided with a spring protection sleeve.

With reference to accompanying drawing 1, a kind of safety muscle training apparatus comprises connecting rod one 2, handle 4, spring 6, spring protective sleeve and connecting rod two 8, and connecting rod one 2 and connecting rod two 8 are identical in size and shape, and connecting rod one 2 and connecting rod two 8 are all bent inward, and the bending angle is greater than 90 degrees. One end of connecting rod one 2 and connecting rod two 8 is hinged by connecting rod connecting pin 1, and the other end is provided with handle 4, and the two ends of spring 6 pass through respectively Spring connecting pin 3 is hinged with the middle position of connecting rod one 2 and connecting rod two 8, and the whole is symmetrical structure, and spring is for preventing from pinching personnel when compressing, and spring protective cover is installed in spring 6 outsides.

The spring protection sleeve can be made of flexible soft material, or two sleeves with different thicknesses, the spring protection inner sleeve 5 and the spring protection outer sleeve 7, the length of the spring protection inner sleeve 5 and the spring protection outer sleeve 7 are all shorter than the spring 6, the spring protection inner cover 5 and the spring protection outer cover 7 are installed on the outside of the spring 6 successively, and can slide relatively.

During the fitness process, hold the handle 4 with both hands, squeeze the handle 4 forcefully to the inside, and perform repeated operations to exercise arm strength. The spring 6 is axially compressed and stressed, and will not be fatigued and damaged due to long-term bending, and will not break, which ensures the safety of personnel. At the same time, the installation of the spring protective cover avoids the unsafe factors caused by the direct exposure of the spring.
