At the same time, the contact block assembly 107 and the auxiliary groove 108 are in anti-slip contact with the wheel, pushing the automatic vehicle to move conveniently and labor-savingly to the top of the device body 1, and then the wheel is controlled to move to the top of the rotating assembly 102, and the moving plate component 204 is pulled up, and the plug-in rod component 207 is pulled outward at the same time, and the spring is pressurized to align the plug-in groove 208 with the wheel axle, and the pulling of the plug-in rod component 207 is stopped, so that the wheel axle is inserted into the inside of the plug-in groove 208, so that the plug-in rod component 207 is connected to the wheel axle, and then the counterweight block 206 is connected to the fixed plate component 205, and with the help of the gravity of the counterweight block 206, the moving plate component 204 and the wheel axle are continuously pressed downward to make the wheel stressed and continuously contact the rotating assembly 102, so as to improve the stability of the automatic vehicle. High anti-slip contact can prevent the driving wheel from sliding when rotating. Then, the clamping rod structure 306 is loosened. The outer rod structure 305, the sliding rod structure 304 and the guide structure 303 are controlled to move left and right and up and down through the clamping rod structure 306, so that the connecting head structure 308 is aligned with the disassembly hole of the middle shaft. The clamping rod structure 306 is controlled to rotate and reset to achieve positioning and fixation, so that the connecting head structure 308 is fixed in a fixed position. Then, the driving motor 104 is controlled to rotate through the controller 101, and the two moving structures 3 are controlled to move in opposite directions through the screw rod, so that the connecting head structure 308 is inserted into the disassembly hole of the middle shaft. Then, the controller 101 controls the rotating component 102 to rotate. The rotating component 102 drives the wheel to rotate quickly. The wheel drives the middle shaft to rotate together through the chain. When rotating, if the stability decreases and tilt occurs, the tilting force is transmitted to the connecting head structure 308 and the sensor 307, so that the sensor 307 detects the stability of the operation of the middle shaft.
