[0027] The motor 24 is started to rotate the threaded rod 25 in a clockwise direction, and the threaded rod 25 and the threaded plate 26 are threadedly connected, thereby driving the threaded plate 26 to move downward, thereby driving the lower connecting rod 27 to move downward along the square slot 23, so that the distance between the two rotating plates 22 is reduced, and the upper connecting rod 27 will move upward along the square slot 23, thereby driving the connecting plate 28 to move upward, and the provided connecting plate 28 will further support the rotating plate 22. At the same time, the provided connecting block 21 will move in the slide groove 201 along the slide rod 202. The provided slide groove 201 and the slide rod 202 ensure that the connecting block 21 will only move left and right, thereby making the two rotating plates 22 can continuously reduce the distance, thereby lifting the platform 32 upward to achieve the effect of lifting. By starting the motor 24, the threaded rod 25 is rotated counterclockwise, thereby making the distance between the diameters of the two rotating plates 22 larger, thereby achieving the effect of descending. The operation is simple and safer, and a better lifting effect is achieved.

[0028] like Figure 2 , Figure 3 As shown, a slide rod 202 is fixedly connected to the surface of the slide groove 201 . The length of the slide rod 202 is consistent with the length of the slide groove 201 , and the slide rod 202 passes through a portion of the connection block 21 away from the rotating plate 22 .

[0029] It should be noted that the provided sliding groove 201 and sliding rod 202 ensure that the connecting block 21 can only move left and right, thereby allowing the two rotating plates 22 to continuously reduce or increase the distance between them.

[0031] It should be noted that the provided groove ensures that the rotating plate 22 can rotate smoothly, and the provided square groove 23 ensures that the support is always present during the lifting process.

[0032] like Figure 4 , Figure 5 As shown, the shock absorbing mechanism 3 includes four shock absorbers 31, the bottoms of the four shock absorbers 31 are fixedly connected to the four corners of the top of the upper lifting plate 29, the tops of the four shock absorbers 31 are fixedly connected to a platform 32, the top of the platform 32 is fixedly connected to a guardrail 33, the bottom of the platform 32 is overlapped with three bent plates 34, the left and right parts of the bottoms of the three bent plates 34 are rotatably connected to two limit blocks 35, a plurality of limit grooves 36 are opened at the top of the upper lifting plate 29, a plurality of baffles 39 are fixedly connected at the top of the upper lifting plate 29, every two baffles 39 are respectively located at the left and right parts of each limit groove 36, the opposite surfaces of every two baffles 39 are fixedly connected to a long rod 37, the left and right parts of the surface of the long rod 37 are movably connected to a buffer spring 38, and the surface of the long rod 37 passes through the middle position of the limit block 35.

[0033] It should be noted that during the lifting process, the platform 32 will produce a certain amount of shaking, causing the platform 32 to move up and down, thereby squeezing the middle position of the bent plate 34. The bent plate 34 is a special steel plate that has both high strength and toughness. Under squeezing, it will extend to both sides, thereby driving the limit block 35 to move along the long rod 37 in the limit groove 36. The limit block 35 and the limit groove 36 are both T-shaped blocks, which ensure that the bent plate 34 will not tilt and fall. The motor 24 will be repeatedly compressed and rebounded, thereby causing the two buffer springs 38 to be repeatedly compressed and expanded. The buffer spring 38 can absorb impact force and reduce vibration to achieve a certain shock absorption effect. At the same time, the shock absorber 31 is repeatedly expanded and contracted to achieve a better shock absorption effect. A guardrail 33 is provided on the platform 32 to provide better safety and achieve higher practicality.

[0034] like Figure 4 , Figure 5As shown, the limiting block 35 and the limiting groove 36 are both in the shape of a T-shaped block, and the height of the limiting block 35 is greater than the depth of the limiting groove 36 .
