The lifting column 8 is driven to move by the set lifting rod 21. An infrared ranging sensor 25 is installed on the top of the moving column 7. The infrared ranging sensor 25 is used to measure the distance between the car roof 1 and the top of the car roof 1. A controller 2 is installed on one side of the top of the car roof 1. The controller 2, the infrared ranging sensor 25 and the lifting motor 22 are electrically connected. Reinforcing ribs 11 are provided at the four corner connections of the positioning plate 10 and the fixed column 4. The reinforcing ribs 11 are arranged in a triangular shape. The connection is supported and fixed by the setting of the reinforcing ribs 11, thereby improving the strength of the fixed column 4. Lockers 26 are installed on the outer surface of the lifting column 8, and the lifting column 8 is connected to the locker 26 by threaded engagement.

[0030] like Figure 4 and Figure 5As shown, a clamping platform 18 is installed in the middle of the bottom of the positioning plate 10, and a clamping groove 19 is provided on the top of the clamping seat 3 at the position of the clamping platform 18. A rotating shaft 12 is installed at the bottom of the clamping groove 19 inside the clamping seat 3, and splints 23 are installed on both sides of the outer surface of the rotating shaft 12. A buckle 24 is installed on the adjacent side of the splints 23 on both sides. Slots 20 are provided on both sides of the clamping platform 18 at the position of the buckle 24, and the buckle 24 is clamped in the inside of the slot 20.
