At this time, when the user leans on the cushion, the back of the user can be heated. And the user can also install and disassemble the connecting cloth 5 as needed. When the connecting cloth 5 is fixed to the soft pad 4 through the sub - buckle 18 and the mother - buckle 19, the bumps 6 on the connecting cloth 5 can press and stimulate the back acupoints of the user. Coupled with the heating of the heating block 17, the physiotherapy effect on the user can be achieved.

[0025] Referring to Figures 1-6, fixed blocks 2 are fixedly connected to the upper and lower parts of both side walls of the substrate 1. The two fixed blocks 2 on both sides are symmetrically distributed. The upper and lower walls of multiple fixed blocks 2 are rotatably connected to rotating shafts 20. One end of each rotating shaft 20 on one side is fixedly connected with a first connecting belt 16. The first connecting belt 16 is wound around the rotating shaft 20 on one side. One end of each of the two first connecting belts 16 far from the rotating shaft 20 penetrates through the fixed block 2 on one side and is fixedly connected with a first buckle 14. The bottom wall of the lower fixed block 2 on one side is rotatably connected to a connecting rod 3. The top end of the connecting rod 3 sequentially penetrates through the rotating shaft 20 and the fixed block 2 and is fixedly connected with a top block 7. The rotating shafts 20 on one side are all fixedly connected with the connecting rod 3. A plurality of positioning holes 12 are formed in the top wall of the upper fixed block 2 on one side. The plurality of positioning holes 12 are evenly distributed in a ring around the outer periphery of the connecting rod 3. Clamping grooves 9 are formed in the front and rear sides of the outer periphery of the top end of the connecting rod 3. Two clamping blocks 13 are slidably connected in the two clamping grooves 9. The outer ends of the two clamping blocks 13 are fixedly connected with a connecting ring 8. The top end of the connecting ring 8 is fixedly connected with a spring 10. The top end of the spring 10 is fixedly connected with the top block 7. The front and rear sides of the bottom wall of the connecting ring 8 are fixedly connected with positioning rods 11 that match the positioning holes 12. The length of the positioning rod 11 is less than the length of the clamping groove 9. The two positioning rods 11 are slidably connected in the positioning holes 12; an adapting assembly, the adapting assembly is arranged in the fixed block 2 on the other side. The adapting assembly can fix the cushion at different positions on the seat. The adapting assembly includes a ruler spring 21. One end of each of the two ruler springs 21 is fixedly connected to the outer periphery of the rotating shaft 20 on the other side. The other end of each of the two ruler springs 21 is fixedly connected with a second connecting belt 22. One end of each of the two second connecting belts 22 far from the ruler spring 21 penetrates through the outer wall of the fixed block 2 on the other side and is fixedly connected with a second buckle 15.

[0026] After placing the cushion on the seat back, when the connecting ring 8 is pulled upward to drive the positioning rod 11 out of the positioning hole 12, by pulling the first buckle 14 and the first connecting belt 16 on one side around the back of the seat and engaging and fixing them with the second buckle 15 on the other side. At this time, by rotating the connecting ring 8, the clamping block 13 can be driven to rotate. Since the clamping block 13 slides and engages in the clamping groove 9, and the clamping groove 9 is formed in the outer periphery of the connecting rod 3, when the connecting ring 8 rotates, the connecting rod 3 can be driven to rotate. When the connecting rod 3 rotates, the two rotating shafts 20 connected correspondingly to the outer periphery can be driven to rotate simultaneously. When the rotating shaft 20 rotates, the first connecting belt 16 can be wound up and the cushion can be tied to the seat back. Since pulling the connecting ring 8 upward will compress the spring 10, after releasing the connecting ring 8, under the action of the spring 10, the connecting ring 8 can be pushed downward to drive the positioning rod 11 to insert into the positioning hole 12 for positioning and fixing. And the spring 10 can also ensure the stability of the positioning rod 11 engaged in the positioning hole 12, so as to facilitate the binding and fixing of different specifications of seats. By simultaneously tightening and fixing multiple first connecting belts 16, the effect of being easy to fix and applicable to different seats can be achieved.

[0027] If fixed at different positions on the same seat, that is, the sizes of the positions on the seat backrest where the upper and lower connecting straps 16 are bound are different, the connecting strap 16 at the position with a larger size on the seat backrest will be tightened in advance. At this time, as the connecting rod 3 continues to rotate, the connecting strap 16 that is tightened in advance will pull the corresponding connecting strap 22 out through the buckle 14 and the buckle 15. When the connecting strap 22 is pulled out, it will tighten the ruler spring 21 until the other connecting strap 16 is tightened and bound to the seat backrest, so as to achieve the effect of adaptively fixing at different positions of the seat backrest.

[0028] Working principle: During actual use, place the cushion on the seat backrest, then pull the buckle 14 and the connecting strap 16 on one side to bypass the rear side of the backrest and engage and fix with the buckle 15 on the other side. Then, rotate the connecting ring 8 to drive the latch 13 and the connecting rod 3 to rotate, which can drive the two rotating shafts 20 on the connected side to rotate, so as to wind up the connecting strap 16 and bind the cushion to the seat backrest. If the sizes of the positions on the seat backrest where the upper and lower connecting straps 16 are bound are different, as the connecting rod 3 continues to rotate, the connecting strap 16 that is tightened in advance will pull the corresponding connecting strap 22 out through the buckle 14 and the buckle 15. When the connecting strap 22 is pulled out, it will tighten the ruler spring 21 until the other connecting strap 16 is tightened and bound to the seat backrest. Then, press down the connecting ring 8 to drive the positioning rod 11 to insert into the positioning hole 12 for positioning and fixing, so as to facilitate the binding and fixing of seats of different specifications.
