[0024] Furthermore, two groups of rotating rods 4 and swing rods 10 are provided, and the position distribution of the two groups of rotating rods 4 and swing rods 10 are symmetrical about the central axis of the base 1, and the other end of the swing rod 10 is rotationally connected to the outer wall of the base 1. The rotating rod 4 forms a rotating structure through the connecting slider 5 and the first slide groove 6 and the fixed block 7, which is conducive to the connecting slider 5 sliding along the inner wall of the first slide groove 6. Through the connection of the fixed block 7, the rotating rod 4 is driven to rotate effectively, thereby playing a role in effectively adjusting the height of the lifting platform 8.

[0025] Furthermore, the slot 14 is arranged in an annular shape on the outer wall of the shaft 2, and the inner wall contour of the slot 14 is larger than the outer wall contour of the bolt 13, which is conducive to the arrangement of the slot 14 in an annular shape on the outer wall of the shaft 2 to play a role in multi-position locking and fixing of the shaft 2 after movement.

[0026] Embodiment 2: Figure 1 , Figure 2 and Figure 4As shown, the utility model proposes an automated hydraulic device for mechanical design and manufacturing.

The threaded slider 17 is fixedly connected to a limit plate 19 on the outside. When working, by setting the limit plate 19, it is beneficial for construction personnel to carry out construction through the automated hydraulic lifting platform. In order to improve the stability of construction personnel on the lifting platform 8, the servo motor 16 can be turned on according to the needs of the construction personnel to drive the threaded slider 17 to slide along the inner wall of the second slide groove 18 through the rotation of the threaded rod 15.
