The front and rear sides of the right end of the left support plate 1 are connected with a first fixing block 6, and the front and rear sides of the left end of the right support plate 2 are connected with a second fixing block 7. A central shaft 8 is rotatably connected between the front first fixing block 6 and the second fixing block 7, and a rectangular hole 9 penetrates between the rear first fixing block 6 and the second fixing block 7.

[0023] A rectangular opening 21 is opened on the upper left side of the right support plate 2. Two horizontal sliding rods 22 are connected in the rectangular opening 21. A moving block 23 is sleeved outside the two horizontal sliding rods 22. A steel wire rope 24 is connected to the left end of the moving block 23. A guide seat 25 is connected to the left end of the right support plate 2. A travel channel 26 is opened in the guide seat 25. A square rod 27 penetrates through the travel channel 26. The front end of the square rod 27 is fixedly connected with the steel wire rope 24. A retaining ring 28 is connected to the outer wall of the square rod 27. A first spring 29 is connected between the retaining ring 28 and the inner wall of the travel channel 26.

[0024] An armrest frame 51 is inserted at the top of the frame head tube 5, and the armrest frame 51 is arranged in a T-shaped structure. A positioning hole 52 is provided at the vertical portion of the armrest frame 51. A positioning bolt 53 is screwed on the upper portion of the outer wall of the frame head tube 5. A vertical groove 54 is provided at the lower portion of the outer wall of the frame head tube 5. An L-shaped column 55 penetrates the vertical groove 54. A round through hole 56 matching the L-shaped column 55 is provided at the top of the right support plate 2. A second spring 57 is connected between the horizontal portion of the L-shaped column 55 and the top wall of the vertical groove 54.

[0025] The left end of the right support plate 2 is connected to a support seat 30 , and the top of the support seat 30 is rotatably connected to a guide wheel 31 , and the steel wire rope 24 abuts against the outer wall of the guide wheel 31 to ensure that the steel wire rope 24 moves stably.

[0026] A limiting frame 11 is connected to the right side of the top of the left support plate 1, and the right end of the limiting frame 11 abuts against the upper surface of the right support plate 2 to prevent the middle section of the frame from folding downward.
