Both ends of the fixed shaft 301 are rotatably provided on the supporting seat in the inner cavity 2, and the fixed shaft 301 is provided with a turbine 302 and a gear 303. 302 is transmission-connected with a worm gear 305 arranged at one end of a rocker 304, the other end of the rocker 304 is arranged on the back of the bracket 1, one end of the rocker 304 is rotationally connected to the inside of the support seat, and the other end is rotationally connected to the inside of the bracket 1, the gear 303 is meshingly connected with a rack 306 arranged at the center of the lifting seat 307, the inside of both sides of the lifting seat 307 is slidingly connected with the first supporting slide bar 308 arranged on both sides of the inner cavity 2, and the top of the lifting seat 307 is provided with an arm exercise component 9 through the top seat 5.

[0027] First sliding grooves 4 are provided inside the two sides of the lifting seat 307 , and the first sliding grooves 4 are slidably connected to the first supporting sliding rods 308 .

[0028] A support rod 13 is provided on one side of the back of the lifting seat 307, and the support rod 13 is slidably connected to a lifting slide groove 14 opened inside one side of the bracket 1, and a pointer 15 is provided on the outer end of the support rod 13, and a scale line 16 is provided on one side of the pointer 15. The scale line 16 is provided on the back of the bracket 1. By providing the support rod 13 and the scale line 16, it is convenient for the operator to adjust the height of the arm exercise component 9 according to the scale line 16 during the process of rotating the rocker 304 on the back of the bracket 1 to lift and lower the arm 304. The height of the arm exercise component 9 can be adjusted according to the reference data of the height of the arm exercise component 9 required for different heights pasted on the back of the bracket 1 according to the operator's own height.

[0029] Storage cavities 17 are provided on both sides of the bracket 1, and the bottom end of the storage cavity 17 is rotatably connected to one end of the seat plate 18.

[0030] In this embodiment, by setting up the lifting component 3, the height of the arm exercise component 9 can be adjusted according to people of different heights, thereby improving the applicability of the device. The rotation of the rocker 304 drives the worm 305 to rotate, which can drive the turbine 302 to rotate, drive the fixed shaft 301 and the gear 303 to rotate, and thus drive the lifting seat 307 to rise and fall along the first supporting slide bar 308, thereby realizing the height adjustment of the arm exercise component 9. At the same time, the adjustment process is relatively easy and convenient, which improves the use effect and ensures stability and safety during use.

[0031] Embodiment 2:

[0032] Based on embodiment one, different from embodiment one, two second supporting slide bars 6 are symmetrically arranged on the front side of the top seat 5, the two second supporting slide bars 6 are slidably connected to the second slide grooves 8 inside the two movable slide blocks 7, and an arm exercise component 9 is arranged at the bottom of the movable slide block 7.

[0033] The arm exercise component 9 includes an elastic rope 901 and a pull ring 902 . One end of the elastic rope 901 is fixedly installed at the center of the bottom of the movable slider 7 , and the other end of the elastic rope 901 is provided with a pull ring 902 .

[0034] In this embodiment, by setting a second supporting slide bar 6 and a movable slider 7, the distance between the arm exercise components 9 at the bottom of the two movable sliders 7 can be adjusted by sliding the movable slider 7 on the second supporting slide bar 6, so that the distance between the arm exercise components 9 can be adjusted according to the requirements of different arm span sizes, thereby improving the applicability of the device.

[0035] Embodiment three:

[0036] Based on the second embodiment, the difference from the second embodiment is that an outer cylinder 10 is provided at the bottom of the movable slider 7, an elastic rope 901 is provided in the cavity 11 of the outer cylinder 10, and an anti-collision pad 12 is provided at the bottom of the outer cylinder 10.

[0037] By arranging the outer tube 10 on the outside of the elastic rope 901, the elastic force of the elastic rope 901 can be avoided from excessively bouncing the pull ring 902, thereby improving the safety protection effect. At the same time, by arranging the anti-collision pad 12 at the bottom of the outer tube 10, the collision between the pull ring 902 and the outer tube 10 can be avoided.

[0038] Working principle: First, adjust the height of the arm exercise component 9 according to the height of the operator, and directly rotate the rocker 304 to adjust the height of the arm exercise component 9. After the adjustment is completed, adjust the distance between the two movable sliders 7 on the second support slide bar 6 according to the operator's own arm extension needs. After the adjustment is completed, hold the pull ring 902 with both hands to exercise the arm through the elastic function of the elastic rope 901. After the exercise is completed, release the hand holding the pull ring 902. Through the reset of the stretched elastic rope 901, the pull ring 902 can be directly driven to instantly bounce up and reset. During the reset process, the outer tube 10 outside the elastic rope 901 is used to prevent the pull ring 902 from bouncing excessively, thereby improving the safety protection effect.
