[0033] Specifically, when using the mechanism, first adjust the stroke of the hydraulic cylinder 13 in the lifting groove 12 using the adjusting rod 14, so that the entire mechanism is lifted up under the action of the hydraulic rod. At this time, the mounting plate 15 pushes the caster 9 out of the lifting groove 12. Then, move the mechanism to the position to be used, and then put the caster 9 back into the lifting groove 12. Then, open the folding plate 3 and the support plate 10 in the folding groove 7. After determining the height of the anti-slip plate 11, lift the support plate 10, and then rotate the adjusting block 33 in the fixing groove 28. The limiting posts 32 on both sides of the adjusting block 33 will move to both sides, and then the outer end of the threaded post 31 will engage with the telescopic frame 30. The side fixing hole 29 is connected, and then the limiting strip 16 at one end of the telescopic frame 30 moves into the limiting groove 21 to fix the angle of the folding plate 3. Then, the limiting block 24 and the positioning rod 25 are pulled. At this time, the mounting shaft 27 is rotated to make the anti-slip plate 11 rotate to the required angle. Then, the hand is released. Under the action of the connecting spring 23, the positioning rod 25 is connected to the positioning hole 26. Then, the position of the support component 2 is adjusted so that the support component 2 is in contact with the bottom surface of the anti-slip plate 11. Then, during use, the orientation of the fixed folding plate 3 is adjusted and fixed by the positioning component 1 as needed. The ball bearing 18 on the bottom surface of the rotating plate 8 facilitates the rotation of the rotating plate 8.

[0034] The positioning component 1 includes a movable plate 105, a rotating shaft 102 fixed on the side of the movable plate 105, and the rotating shaft 102 is rotatably connected to the adjustment channel 17. A reset spring 101 is fixed in an array between the movable plate 105 and the adjustment channel 17. A pressing groove 103 is opened on the top surface of the movable plate 105. A gear rack 104 is fixed on the bottom surface of the movable plate 105, and the gear rack 104 is movably connected to the limiting gear ring 19.

[0035] Specifically, in the positioning component 1, under the action of the return spring 101, the movable plate 105 moves downward with the gear rack 104. At this time, the gear rack 104 engages with the limiting gear ring 19 for positioning, thereby fixing the horizontal orientation of the folding plate 3 and the support plate 10 on the rotating plate 8. After the folding plate 3 and the support plate 10 are connected, the rotating plate 8 can be controlled to rotate and be positioned on the base 4 by pressing the movable plate 105. This design is simple in structure and convenient to operate, allowing the mechanism to be adjusted in horizontal orientation during use, thus improving the user experience.

[0036] The support component 2 includes a mounting frame 202, which is movably connected to the folding plate 3. A limiting plate 206 is fixed on the bottom surface of the mounting frame 202, and the limiting plate 206 is movably connected to the moving groove 5. A support seat 201 is provided inside the mounting frame 202, and the support seat 201 is rotatably connected to the mounting frame 202. A moving groove 204 is provided on the side of the mounting frame 202, and a moving block 203 is provided in the moving groove 204. The moving block 203 is movably connected to the moving groove 204 and the positioning groove 6 respectively. A counterweight 205 is provided in the positioning seat.

[0037] Specifically, in the support component 2, the mounting frame 202 can be moved and adjusted in the moving groove 5 via the limiting plate 206. When the support seat 201 on the mounting frame 202 is in contact with the bottom surface of the protective plate, the position of the support seat 201 can be fixed by moving the movable block 203 into the positioning groove 6. The support seat 201 can rotate in the mounting frame 202, which facilitates full contact between the support seat 201 and the anti-slip plate 11 at different angles. This design allows the mechanism to be adaptively adjusted according to the angle of the anti-slip plate 11, so that the weight of the support can be transferred to the folding plate 3 through multiple channels, thereby improving the stability of the mechanism.

[0038] Working principle: In positioning component 1, under the action of return spring 101, movable plate 105 moves downward with gear rack 104. At this time, gear rack 104 meshes with limiting gear ring 19 for positioning, thereby fixing the horizontal orientation of folding plate 3 and support plate 10 on rotating plate 8. After folding plate 3 and support plate 10 are connected, pressing movable plate 105 can control rotating plate 8 to rotate and position on base 4. In support component 2, mounting frame 202 can be moved and adjusted in moving groove 5 through limiting plate 206. When support seat 201 on mounting frame 202 is in contact with the bottom surface of protective plate, moving movable block 203 into positioning groove 6 can fix the position of support seat 201. Support seat 201 can rotate in mounting frame 202, which facilitates full contact between support seat 201 and anti-slip plate 11 at different angles.

[0039] When using the mechanism, first adjust the stroke of the hydraulic cylinder 13 in the lifting groove 12 using the adjusting rod 14, so that the entire mechanism is lifted up under the action of the hydraulic rod. At this time, the mounting plate 15 pushes the caster 9 out of the lifting groove 12. Then, move the mechanism to the desired position and put the caster 9 back into the lifting groove 12. Then, open the folding plate 3 and the support plate 10 in the folding groove 7. After determining the height of the anti-slip plate 11, lift the support plate 10. Then, rotate the adjusting block 33 in the fixing groove 28. The limiting posts 32 on both sides of the adjusting block 33 will move to both sides. Then, the outer end of the threaded post 31 will engage with the inner side of the telescopic frame 30. The fixing hole 29 is connected, and then the limiting strip 16 at one end of the telescopic frame 30 moves into the limiting groove 21 to fix the angle of the folding plate 3. Then, the limiting block 24 and the positioning rod 25 are pulled. At this time, the mounting shaft 27 is rotated to make the anti-slip plate 11 rotate to the required angle. Then, the hand is released. Under the action of the connecting spring 23, the positioning rod 25 is connected to the positioning hole 26. Then, the position of the support component 2 is adjusted so that the support component 2 is in contact with the bottom surface of the anti-slip plate 11. Then, during use, the orientation of the fixed folding plate 3 is adjusted and fixed by the positioning component 1 as needed. The ball bearing 18 on the bottom surface of the rotating plate 8 facilitates the rotation of the rotating plate 8.
