[0009] Furthermore, threaded holes cooperating with the screw rods are provided inside the two movable sleeve blocks, and the threads in the two threaded holes are in opposite directions.

[0022] In order to make the purpose, features, and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the embodiments described below are only part of the embodiments of the present application, not all of the embodiments.

A servo motor 3 is set at one end of the slide rail 2, and the output end of the servo motor 3 rotates through the positioning frame 1 and the slide rail 2. A screw rod is fixed to one end of the servo motor 3 extending to the inside of the slide rail 2, and the screw rod is rotatably connected to the inside of the slide rail 2 through a bearing. A moving sleeve block 4 is symmetrically slidably sleeved inside the slide rail 2. Threaded holes matching the screw rods are opened inside the two moving sleeve blocks 4, and the threads in the two threaded holes are in opposite directions. The slide rail 2 is opened with a screw rod. The movable sleeve block 4 cooperates with the laterally placed "convex" slide groove, and the movable sleeve block 4 is threadedly sleeved on the screw rod, and the two movable sleeve blocks 4 are fixed with a splint 5 at one end extending to the outside of the slide rail 2, and the splint 5 is provided with a laser sensor 7 on the opposite side of the end of the slide rail 2, and the opposite sides of the two splints 5 are glued and fixed with anti-skid rubber pads 6, and the thickness of the anti-skid rubber pads 6 is less than the thickness of the laser sensor 7, and laser sensors 8 are staggered on the positioning frame 1 at the upper and lower ends of the middle part of the slide rail 2.

At this time, the servo motor 3 runs to drive the screw rod to rotate, which can drive the two movable sleeves 4 to move relative to each other, thereby driving the two clamping plates 5 to move relative to each other. When the clamping plate 5 moves to drive the anti-slip rubber pad 6 to fit and clamp the car body, the laser sensor 7 detects the signal and feeds it back to the servo motor 3. After the car is loaded or unloaded, the servo motor 3 runs to drive the screw rod to rotate in the opposite direction, and under the action of the thread, the clamping plate 5 can be driven to move in the opposite direction to separate from the car, and the car can move.

Each support plate 15 has symmetrical mounting holes inside, and the connecting screw 11 extends to the end of the outer side of the adjustment support plate 9 and is threadedly sleeved with a fixing nut 12.

[0026] When the positioning frame 1 needs to be separated from the fixed base plate 14 and adjusted in position, the bolts inside the threaded groove 17 on the top surface of the connecting base plate 13 are screwed into place.
