By setting the diagnostic mechanism 3, when the hollow block 2 approaches the wheel hub body 1, the elastic rubber column 301 will first come into contact with the wheel hub body 1. As the hollow block 2 continues to move, it will cause the elastic rubber column 301 to drive the rectangular plate 302 to move, and the rectangular plate 302 drives the pressure sensor 303. After the pressure sensor 303 comes into contact with the hollow block 2, the elastic rubber column 301 will deform, causing the pressure sensor 303 to exert an extrusion force on the hollow block 2, so that the pressure sensor 303 detects a pressure value. After the connection becomes loose, the hollow block 2 will move away from the hollow block 2. At this time, the pressure sensor 303 will detect a decrease in the pressure value or even the disappearance of the pressure value, and then transmit a signal to the central processor. The central processor will control the buzzer and the warning light to work to remind the driver. A slide bar 305 is slidably connected to the inner cavity of the rectangular plate 302, and one side of the slide bar 305 is fixedly connected to the hollow block 2.

After the pressure sensor 303 contacts the hollow block 2, the elastic rubber column 301 will deform, so that the pressure sensor 303 generates a squeezing force on the hollow block 2, so that the pressure sensor 303 detects a pressure value. After the connection becomes loose, the hollow block 2 will move away from the hollow block 2. At this time, the pressure sensor 303 will detect that the pressure value drops or even the pressure value disappears. Then, a signal will be transmitted to the central processor, and the central processor will control the buzzer and the warning light to work to remind the driver;

[0025] By providing the connecting mechanism 4, the support belt 5 is placed outside the hub body 1, and the support belt 5 is made to correspond to the hollow block 2. Then, the iron rod 407 is pulled outward. The iron rod 407 drives the connecting pin 404 to move outward. Then, the hollow block 2 is brought close to the hub body 1. Subsequently, the fixing block 405 will contact the connecting seat 406. Then, the iron rod 407 is released. The iron plate 402 is driven to move by the thrust of the second spring 403. The iron plate 402 drives the connecting pin 404 to move, so that both the fixing block 405 and the connecting seat 406 are inserted into the connecting pin 404. At this time, the iron plate 402 will contact the magnetic block 401, and the electromagnet 408 generates a suction force on the iron rod 407, thereby making the working of the connecting pin 404 stable, and the installation work can be completed.
