One end of the folding leg 6 is externally rotatably connected to the third U-shaped frame 7 through a pin. A sliding seat 8 is fixed to one side of the three third U-shaped frames 7. The cylinder 1 is slidably connected to the sliding seat 8. One side of the sliding seat 8 is internally threadedly connected There is a threaded handle 9. When the device is to be unfolded, the sliding seat 8 is held by hand and slides downward on the surface of the cylinder 1. The sliding seat 8 drives the third U-shaped frame 7 to slide, the third U-shaped frame 7 drives the folding legs 6 to rotate, the folding legs 6 drive the second U-shaped frame 5 to rotate, the second U-shaped frame 5 drives the connecting bar 4 to rotate, and the connecting bar 4 rotates around the first U-shaped frame 3, so that the bottom of the device can be unfolded, and the threaded handle 9 is held by hand to rotate. Since the sliding seat 8 and the threaded handle 9 are threadedly connected, the sliding seat 8 is squeezed by the rotation of the threaded handle 9, so that the sliding seat 8 can be tightly fixed on the surface of the cylinder 1. When it is necessary to fold, just repeat the opposite operation steps;
[0032] The height adjustment mechanism includes a clamping chamber 10, a clamping knob 11, a bearing 12, a clamping block 13 and a telescopic rod 14. A clamping chamber 10 is fixed to one side of the top of the cylinder 1. The clamping chamber 10 is internally threadedly connected with a clamping knob 11.

The bottom of the circular disk 20 is in close contact with a spring 23, the spring 23 is slidably connected to the limiting cavity 19, and the limiting rod 21 is slidably connected to the extension plate 15. When the panel 2 is to be expanded, the pulling handle 18 is held and pulled out from the inside of the handle seat 17, thereby driving the extension plate 15 to slide inside the panel 2. Since a hole is provided at one end of the bottom of the extension plate 15, when the hole passes above the limiting rod 21 during pulling, the compressed spring 23 stretches so that the spring 23 pushes the circular disk 20. The circular disk 20 drives the limiting rod 21 to enter the inside of the extension plate 15, so that the position of the extension plate 15 can be limited, so that it cannot move freely, thereby realizing the expansion of the device;
[0035] A connecting block 24 is fixed at the bottom of the panel 2, and the telescopic rod 14 and the connecting block 24 are threadedly connected. Through the setting of the connecting block 24, the panel 2 and the telescopic rod 14 can be stored separately to minimize the occupied space, and at the same time, flexible disassembly is achieved for easy movement and carrying;

[0038] When the device is to be unfolded, the sliding seat 8 is held by hand and slides downward on the surface of the cylinder 1, the sliding seat 8 drives the third U-shaped frame 7 to slide, the third U-shaped frame 7 drives the folding legs 6 to rotate, the folding legs 6 drive the second U-shaped frame 5 to rotate, the second U-shaped frame 5 drives the connecting bar 4 to rotate, the connecting bar 4 rotates around the first U-shaped frame 3, and the bottom of the device can be unfolded, and the threaded handle 9 is held by hand to rotate. Since the sliding seat 8 and the threaded handle 9 are threadedly connected, the sliding seat 8 is squeezed by the rotation of the threaded handle 9, and the sliding seat 8 can be tightly fixed on the surface of the cylinder 1. When it is necessary to fold, just repeat the reverse operation steps;
[0039] When the height of the device is to be adjusted, the telescopic rod 14 is pulled to slide inside the cylinder 1. When it is pulled to a suitable height, the clamping knob 11 is turned by hand. Since the clamping cavity 10 and the clamping knob 11 are threadedly connected, the clamping knob 11 drives the bearing 12 and the clamping block 13 to slide inside the clamping cavity 10, so that the surfaces of the clamping block 13 and the telescopic rod 14 are closely fitted, so that the telescopic rod 14 can be clamped, and the height adjustment of the device can be achieved.
[0040] When the panel 2 is to be expanded, the pulling handle 18 is held and pulled out from the handle seat 17, thereby driving the extension plate 15 to slide inside the panel 2. Since a hole is provided at one end of the bottom of the extension plate 15, when the hole passes over the limiting rod 21 during pulling, the compressed spring 23 stretches so that the spring 23 pushes the circular disk 20. The circular disk 20 drives the limiting rod 21 to enter the extension plate 15, thereby limiting the position of the extension plate 15 and preventing it from moving freely, thereby realizing the expansion of the device.
