[0031] The driving bevel gear 19 is rotatably connected to the inner wall of the sleeve 4. The driving bevel gear 19 passes through the sleeve 4 and is fixedly connected to the driving block 20;

[0032] The folding assembly includes a connecting block 3 fixedly connected to the outer wall of the crossbeam 1 and the top wall of the support tube 5, the inner wall of the connecting block 3 is slidably connected to the plug-in block 7, the outer wall of the plug-in block 7 is fixedly connected to the side plate 8, the inner wall of the plug-in block 7 is slidably connected to the symmetrically distributed positioning blocks 13, the inner wall of the plug-in block 7 is fixedly connected to the symmetrically distributed sliding rod 15, and the sliding rod 15 is slidably connected to the positioning block 13, the outer wall of the sliding rod 15 is provided with a strong spring 16, the outer wall of the positioning block 13 is provided with an inclined surface 14, the positioning block 13 is located on the inner wall of the connecting block 3, the plug-in block 7 is inserted into the connecting block 3, and is located on the inner wall of the plug-in block 7 The positioning block 13 will be squeezed by the inner wall of the connecting block 3. Since the outer wall of the positioning block 13 is provided with an inclined surface 14, during the insertion process, the inner wall of the connecting block 3 will push the positioning block 13 along the inclined surface 14 to slide into the inside of the plug-in block 7. At this time, the slide bar 15 plays a guiding role, and the strong spring 16 sleeved on the outer wall of the slide bar 15 is compressed. When the positioning block 13 passes the corresponding position inside the connecting block 3, under the elastic force of the strong spring 16, the positioning block 13 is reset and popped out, and is stuck in the corresponding position of the inner wall of the connecting block 3, thereby achieving stable connection and positioning between the crossbeam 1 and the plug-in block 7;

[0033] The adjusting component is arranged on the inner wall of the sleeve 4.

[0034] like Figures 2-4As shown, as a preferred embodiment, on the basis of the above manner, further, the outer wall of the side plate 8 is fixedly connected with the symmetrically distributed arc-shaped frame 9, the outer wall of the arc-shaped frame 9 is provided with uniformly distributed limiting holes 10, the inner wall of the limiting hole 10 is slidably connected with a limiting block 12, and the inner wall of the limiting block 12 is threadedly connected with a bidirectional screw rod 11. The corresponding arc-shaped frames 9 are connected, and the limiting of the arc-shaped frame 9 is realized through the threaded cooperation between the bidirectional screw rod 11 and the limiting block 12.
