[0025] The lifting assembly 4 includes a first support arm 401 rotatably connected to one end of the top of the bottom plate 1, and a second support arm 402 rotatably connected to one end of the bottom of the lifting plate 5. The middle parts of the first support arm 401 and the second support arm 402 are rotatably connected. A support shaft 406 is rotatably connected through the rotational connection part of the first support arm 401 and the second support arm 402.

Then turn the crank 410, so that the threaded rod 407 rotates, and then drive the push block 408 to move, so that the lifting strut 409 pushes the support shaft 406 to move, and then the connecting shaft 404 of the first arm 401 and the second arm 402 slides along the sliding groove 403, so that the first arm 401 and the second arm 402 push the lifting plate 5 to lift and lower, flexibly adjusting the height of the lifting plate 5 to meet the construction operation requirements of different heights. When it stops being used, reverse-rotate the roller 7 and the crank 410, so that the displacement block 11 moves in the reverse direction, lower the protection frame 13, which is convenient for workers to get on and off, while reducing the height and volume of the whole device, and at the same time lowering the height of the lifting plate 5 for convenient placement.
