The top of the connecting extrusion column 6, the outer end of the extension connecting rod 10 and the bottom end of the second lifting push rod 11 are all connected with a rotating connecting column 18. The corresponding inner end of the connecting extrusion column 6 is connected with a compression suction cup 7. An adsorption hole 20 is opened in the outer side surface of the compression suction cup 7. The adsorption hole 20 is mainly used to improve the adsorption of the compression suction cup 7, enhance the clamping firmness, and extend the suction cup 7. One end of the extension connecting rod 10 is connected to the side end surface of the lifting installation box 4, and the other end is rotatably connected to the top end of the second rotating connecting rod 9 through a rotating connecting column 18. The ends of the second rotating connecting rod 9 and the first rotating connecting rod 8 that are close to each other are rotatably connected to the top end of the connecting extrusion column 6 through a rotating connecting column 18.

The inner side of the crossbeam 2 is close to the outer side surface of the sliding car box 3. The slide groove 14 is mainly used to facilitate the left and right horizontal movement of the sliding car box 3 through the external driving mechanism. The outer extension end of the sliding car box 3 is slidably connected to the inner side of the movable slide groove 14. A plurality of warning lights 19 are installed at the bottom of the front end of the crossbeam 2. The warning lights 19 mainly serve as warning reminders, indicating that work is in progress and safety tips should be paid attention to.

[0040] The working principle and use process of the utility model are as follows: first, when in use, the threaded rotating rod 12 is rotated by the operation of the driving motor 13, so that the first lifting push rod 5 in the sliding car box 3 moves up and down and pushes the lifting installation box 4.
