[0027] like Figure 1 As shown, the pull-up special power belt includes an elastic belt 1 and a fixing device matched with the horizontal bar; both ends of the elastic belt 1 are provided with connecting rings 2 through which the strap 5 is passed. The fixing device includes the strap 5 and the clip 6. Figure 2 As shown, the clamp 6 includes a clamp plate 7 and a frame 8 for mounting the clamp plate 7. The clamping end of the clamp plate 7 is provided with an engaging tooth 9, and the inner side of the clamp plate 7 is provided with two shaft cavities with a gap, and a shaft 11 is passed through the shaft cavity. A spring 12 is sleeved on the shaft 11, and the spring 12 is located in the gap. The first force-bearing end 14 of the spring 12 is in contact with the clamp plate 7, and the second force-bearing end 15 of the spring 12 is in contact with the bracket 16. The clamp plate 7 is pressed, and the strap 5 passes through the gap between the engaging tooth 9 and the anti-slip pattern 10, and the clamp plate 7 is released, and the clamp plate 7 clamps the strap 5. The bracket 16 is fixed on the frame 8, and a groove 17 for accommodating the second force-bearing end 15 is provided on the bracket 16. The front end of the frame 8 is fixedly provided with a baffle 18, and the inner side of the baffle 18 is provided with an anti-slip pattern 10, and the anti-slip pattern 10 is opposite to the engaging tooth 9. The anti-slip pattern 10 is an anti-slip horizontal pattern, so that the strap 5 and the baffle 18 fit well, so that the strap 5 is firmly clamped. A connecting rod 19 for installing the strap 5 is provided at the rear end of the frame 8. A strap 5 is passed through the connecting ring 2 at one end of the elastic band 1, and then the strap 5 is hung on the horizontal bar, and the strap 5 is inserted into the clip 6 on the strap 5 to be connected and fixed. Another strap 5 is passed through the connecting ring 2 at the other end of the elastic band 1, and then the strap 5 is also hung on the horizontal bar, and the strap 5 is inserted into the clip 6 on the strap 5 to be connected and fixed, so that the elastic band 1 is hung on the horizontal bar. The present application adopts the form of hanging the strap 5 on the horizontal bar through the clip 6 with anti-slip texture 10 and bite teeth 9, so that the connection between the power-assisting belt and the horizontal bar is firm, ensuring that the power-assisting belt will not fall off, improving the safety of exercise, and the length of the power-assisting belt can be freely adjusted according to the height and physical fitness of different people by lengthening and tightening the strap 5. Figure 3 As shown, the strap 5 is woven from polyester fibers and has scale lines 21 woven thereon for easy memory adjustment.

[0028] like Figure 4As shown, the middle part of the elastic belt 1 is a rigid belt 4 without elasticity. Elastic parts 20 are extended from both ends of the rigid belt 4. Connecting rings 2 are arranged at the ends of the elastic part 20. The elastic part 20 adopts a corrugated elastic belt, which is formed by covering a webbing on a rubber bundle, and is wear-resistant and durable. Connecting ropes connected to the rubber bundle are evenly arranged on the inner wall of the webbing. The rigid belt 4 and the elastic part 20 are interwoven and seamlessly connected. The presence of the rigid belt 4 makes the installation of the seat plate 3 more convenient. There are two to three elastic belts 1, so that the power-assisting belt can withstand greater force and provide better support for the exerciser.

[0029] The lower end surface of the rigid belt 4 is provided with a non-slip webbing 13 for the human body to step on. The upper end surface of the rigid belt 4 is provided with a seat board 3 for the human body to kneel on; the seat board 3 is made of a flexible sponge wrapped with a breathable mesh cloth. The existence of the breathable seat board 3 enables the exerciser to kneel on the seat board 3 to do pull-ups, and the skin in contact with the seat board 3 is kept dry and comfortable during exercise, while exercising the upper limbs, shoulder straps and back muscles, which is more conducive to enhancing the coordination and balance of the body.

[0030] When exercising, first, the strap 5 is passed through the connecting ring 2, and then the strap 5 is hung on the horizontal bar, and then one end of the strap 5 is passed through the clip 6, and the strap 5 is tightened, and the anti-skid pattern 10 and the bite teeth 9 clamp the strap 5. Hold the horizontal bar with both hands, step on the anti-skid webbing 13, and then kneel on the seat board 3 to do pull-up exercises.
