[0025] The reinforcement component 5 includes a telescopic rod 51, with sliding plates 53 fixedly connected to both ends of the telescopic rod 51. Positioning rods 54 are welded to one end of each sliding plate 53 relative to the telescopic rod 51. A return spring 52 is sleeved on the outside of the telescopic rod 51 between the two sliding plates 53. A positioning groove 11 is provided on the outside of the column 4 for the positioning rod 54 to be inserted. One end of the positioning rod 54 is provided with a rounded corner 56. The return spring 52 facilitates the quick insertion of the positioning rod 54 into the positioning groove 11, thereby facilitating the positioning and support of the column 4 and improving the stability of the column 4.

[0026] The support assembly 2 includes a connecting plate 21. Support cylinders 24 for sliding of the column 4 are welded on both sides of the connecting plate 21. A sliding chamber 22 is provided in the inner cavity of the connecting plate 21 for sliding of the slide plate 53. A guide groove 23 is provided between the sliding chamber 22 and the two sets of support cylinders 24 for the positioning rod 54 to pass through. The sliding chamber 22 limits the position of the slide plate 53, thereby improving the stability of the positioning rod 54. The operation is simple and convenient, saving the operation time of lifting the steel platform 3.

[0027] A slider is fixedly connected to the outside of the column 4. A groove 25 is provided on the inner wall of the support cylinder 24 for the slider to slide. A buffer spring 12 is provided at the bottom of the inner cavity of the support cylinder 24. A pad 13 is provided at the upper end of the buffer spring 12.

Each set of sliding plates 53 is fixedly connected to a paddle 55 that is slidably disposed in the through hole 26. One end of the upper surface of one set of paddles 55 is rotatably connected to a flip plate 57. One end of the lower surface of the flip plate 57 is fixedly connected to a hook block 58. The hook block 58 is used to hook the paddle 55, so that the positioning rod 54 can be disengaged from the positioning groove 11, thereby facilitating the descent of the steel platform 3 and improving the convenience of operation.

[0029] The limiting assembly 7 includes a fixing plate 71 fixedly connected to the upper surface of the base 1. An adjustment knob 75 is threadedly connected to one side of the fixing plate 71. One end of the adjustment knob 75 passes through the fixing plate 71 and is rotatably connected to a limiting ring 74. A sliding plate 72 is fixedly connected to one side of the limiting ring 74. A toothed plate 73 is fixedly connected to the upper end of one side of the sliding plate 72. The position of the sliding plate 72 can be easily adjusted by adjusting the knob 75, thereby facilitating the meshing of the toothed plate 73 with the limiting gear 63.

[0030] A handwheel 64 and a limiting gear 63 are fixedly connected to the upper end of the rotating shaft 61 from top to bottom. The teeth of the limiting gear 63 mesh with the teeth of the toothed plate 73. By using the meshing of the limiting gear 63 with the toothed plate 73, the stability of the lifting assembly 6 is improved when it is not in use, and misoperation is avoided.

[0031] The lower surface of the base 1 is provided with multiple sets of anti-slip base plates 8, and the upper surface of the steel platform 3 is bonded with an anti-slip pad 9. The upper surface of the anti-slip pad 9 is provided with multiple sets of anti-slip ridges 10. The anti-slip ridges 10 improve the anti-slip effect on the steel platform 3 and enhance safety.

[0032] In use, rotating the adjustment knob 75 disengages the toothed plate 73 on the sliding plate 72 from the limiting gear 63. Then, rotating the handwheel 64 drives the rotating shaft 61, which in turn drives the first sprocket 62. The first sprocket 62, via the chain 65, drives the second sprocket 67 on the screw 66, causing the screw 66 to lift the screw cylinder 68. The column 4 slides within the support cylinder 24, ensuring the stability of the steel platform 3 during lifting. Simultaneously, the column 4 rises along the support cylinder 24. During this lifting process, the rounded corner 56 of the positioning rod 54 abuts against the positioning groove 11, resetting the spring. The elastic potential energy of spring 52 causes slide plate 53 to drive positioning rod 54 to abut against the outer wall of column 4, thereby lifting steel platform 3 to a specified height by lifting assembly 6. Positioning rod 54 then inserts into positioning groove 11 to support column 4, further improving the stability of steel platform 3 after lifting. When lowering steel platform 3, press two levers 55 and hook the hook block 58 on flip plate 57 to compress return spring 52, causing positioning rod 54 to disengage from positioning groove 11, so that steel platform 3 can be lowered by lifting assembly 6. The operation is simple and convenient, improving practicality.
