[0026] A rotating screw 3 is rotatably connected between the two support seats 2, and the threads of the rotating screw 3 at both ends of the axial direction are opposite. A motor 16 is installed on the outer wall of the right support seat 2, and the output end of the motor 16 is fixedly connected to one end of the rotating screw 3, and the motor 16 is electrically connected to the controller 17. The first rotating block 4 and the second rotating block 5 are respectively threadedly connected on the rod body of the rotating screw 3. Two first sliding grooves 12 are provided on the upper surface of the load-bearing base plate 1, and two second sliding blocks 14 are slidably connected inside the two first sliding grooves 12. Auxiliary rods 15 are welded on the outer walls of the four second sliding blocks 14, and the other ends of the four auxiliary rods 15 are respectively connected to the first rotating block 4 and the second rotating block 5. The upper surface of the first rotating block 4 is rotatably connected to the first rotating rod 6, and the upper surface of the second rotating block 5 is rotatably connected to the second rotating rod 7. Fixing bolts 8 are installed on the rod bodies of the first rotating rod 6 and the second rotating rod 7, and fixing nuts 9 are threadedly connected to the fixing bolts 8.

When not in use, the limiting bolt 28 is taken out, and the fixing block 24 is held to drive the rotating shaft 23 to rotate downward, thereby driving the support frame 25 and the loading hook 26 to move downward, until the support frame 25 and the loading hook 26 enter the storage groove 22 for storage, and then the limiting bolt 28 is inserted to fix it, thereby reducing the occupied area and improving convenience.

[0028] Working principle: When in use, the motor 16 is turned on through the controller 17 to drive the rotating screw 3 to rotate forward or reverse. Since the threads of the rotating screw 3 on the two end surfaces along its axial direction are opposite, the first rotating block 4 and the second rotating block 5 are driven to move to the middle or both sides at the same time, thereby driving the auxiliary rod 15 and the second sliding block 14 to slide inside the first sliding groove 12. The second sliding block 14 limits and guides it, so that the first rotating rod 6 and the second rotating rod 7 move up or down, thereby driving the first sliding block 10 to slide in the second sliding groove 21, so that the loading platform body 11 moves up or down. After moving to a suitable height, the fixing bolts 8 are inserted into the first rotating rod 6 and the second rotating rod 7, and the fixing nuts 9 are screwed on to fix them, so that the height of the loading platform body 11 can be adjusted according to different vehicle models for carrying and use, thereby increasing the user's experience and improving the practicality of the device. The device is convenient to move when in use by setting four moving wheels 18, and five electric telescopic rods 19 are turned on by the controller 17, which drive the suction cup 20 to move downward, and the plane on which the device is placed is adsorbed, so that it is convenient to fix and use. Items of different shapes can be placed on the loading platform body 11, which is convenient for storage and placement. By setting a protective frame 29, it is possible to effectively prevent items from slipping. By setting a support frame 25 and a loading hook 26, it is convenient to hang and store some items, thereby further improving the practicality of the device. When not in use, take out the limit bolt 28, hold the fixing block 24 to drive the rotating shaft 23 to rotate downward, and then drive the support frame 25 and the loading hook 26 to move downward, until the support frame 25 and the loading hook 26 enter the storage slot 22 for storage, and then insert the limit bolt 28 to fix it, thereby reducing the occupied area and improving convenience.
