When in use, the end of the plug plate 204 can pass through the inside of the through groove, and the top block 203 is fixed to the top of the clamping block 102. A screw hole is provided inside the top block 203. When in use, the screw hole and the stud 202 are screwed together through a thread. The inside of the screw hole is provided with a stud 202, and the bottom of the stud 202 extends to the upper surface of the plug plate 204. The top of the stud 202 is fixedly provided with a handle. Through the designed buffer component, when the clamping block 102 squeezes and clamps the wheel hub in use, the rubber buffer plate 200 on the mounting plate 201 in the clamping block 102 contacts with the surface of the wheel hub. The rubber buffer plate 200 plays a buffering role, reduces the situation where the clamping block 102 produces clamping marks and damages on the surface of the wheel hub, and is convenient for use.

[0023] In this embodiment, preferably, a screw hole is opened inside the vertical plate 109, a screw rod 107 is arranged inside the screw hole, and a bearing is embedded and installed inside the movable plate 110. When in use, the bearing can be used to prevent the movable plate 110 from rotating when the screw rod 107 is rotated. The working end of the screw rod 107 extends to the inside of the bearing, and cleaning components are arranged on both sides of the vertical plate 109. The cleaning components include an arc block 300, and a mounting brush 301 is fixedly arranged on the inner wall of the arc block 300. A connecting plate 302 is fixedly arranged on the front and back sides of the arc block 300. The connecting plate 302 is fixedly connected to the vertical plate 109 by screws.

[0026] The working principle and use process of this utility model:

[0027] When the utility model is in use, the end of the plug plate 204 on the side of the mounting plate 201 on the rubber buffer plate 200 is passed through the through slot in the top block 203, and then the mounting plate 201 contacts the inclined surface of the clamping block 102. At this time, the handle on the top of the stud 202 is held and rotated downward to drive the stud 202 to rotate, and then the bottom of the stud 202 contacts and fixes the plug plate 204. At this time, the mounting plate 201 can be installed. When the clamping block 102 clamps the outer wall of the wheel hub in use, the surface of the rubber buffer plate 200 contacts the outer wall of the wheel hub, and the rubber buffer plate 200 plays a buffering role, reducing the situation of pinch marks and damage to the outer wall of the wheel hub. When it is necessary to disassemble the mounting plate 201 and the rubber buffer plate 200, the operation can be carried out according to the opposite principle mentioned above;

[0028] The debris generated during the processing and drilling of the wheel hub will adhere to the outer wall of the screw 107, and the debris will cause wear between the screw 107 and the screw hole. At this time, when the screw 107 is rotating, the debris will be swept away by the installation brush 301, reducing the chance of the debris causing wear on the screw 107. The arc block 300 and the installation brush 301 can be removed by unscrewing the screws on the connecting plate 302, and there is no need to manually clean the debris attached to the outer wall of the screw 107 every time the screw 107 is rotated.
