The shape of the trapezoidal clamping groove 203 is trapezoidal.

[0032] Embodiment Two

[0033] Please refer to Figures 1-5, the insert 3 is arranged on the side of the mounting seat 2 away from the hub body 1, and a part of the insert 3 is snapped into the inside of the mounting seat 2. When the insert 3 is snapped into the inside of the mounting seat 2, the installation of the lead block 301 can be completed. The insert 3 includes the lead block 301 arranged on the side of the mounting seat 2 away from the hub body 1. There are several groups of lead blocks 301. The overall weight of the wheel can be adjusted by increasing or decreasing the number of installed lead blocks 301. A part of the connecting block 302 is inserted into the inside of the insertion slot 202. The connecting block 302 is used to connect the trapezoidal clamping block 303, the support telescopic rod 304 and the spring 305. The side of the lead block 301 away from the insert 3 is welded with the connecting block 302. Trapezoidal clamping blocks 303 are arranged on both the top and bottom surfaces of the connecting block 302. The structural shape of the trapezoidal clamping block 303 is trapezoidal and is adapted to the shape of the trapezoidal clamping groove 203. There are two groups of trapezoidal clamping blocks 303, and the two groups of trapezoidal clamping blocks 303 are symmetrically distributed on the transverse central axis of the lead block 301. A support telescopic rod 304 is arranged between the trapezoidal clamping block 303 and the connecting block 302. One end of the support telescopic rod 304 is threadedly connected to the inner side wall of the trapezoidal clamping block 303, and the other end of the support telescopic rod 304 is threadedly connected to the outer side wall of the connecting block 302.

The end of the trapezoidal clamping block 303 away from the support telescopic rod 304 extends into the inside of the trapezoidal clamping groove 203 and is snapped into the inside of the trapezoidal clamping groove 203.

[0034] Embodiment III

[0035] Please refer to Figures 1-5 , a square clamping groove 205 is formed on the outer side wall of the mounting block 201. The structural shape of the square clamping groove 205 is rectangular. The end shape of the sealing side plate 204 is adapted to the square clamping groove 205.

A sealing side plate 204 is hinged on the outer side wall of the mounting block 201. The end of the sealing side plate 204 is inserted into the inside of the square clamping groove 205. After the lead block 301 is installed into the inside of the mounting seat 2, the end of the sealing side plate 204 can be inserted into the inside of the square clamping groove 205 to prevent the lead block 301 from slipping out.

[0036] Working principle: First, measure the weight of the wheel hub, take out the corresponding number of lead blocks 301, and match them with the weight that the wheel hub needs to be adjusted. Then, hold the two sets of trapezoidal blocks 303 and apply a squeezing force towards the outer wall direction of the connecting block 302;

[0037] Secondly, under the cooperation of the telescopic functions of the support telescopic rod 304 and the spring 305, the trapezoidal block 303 moves towards the outer wall direction of the connecting block 302. Then, horizontally insert the connecting block 302 and the trapezoidal block 303 into the inside of the insertion slot 202. When the trapezoidal block 303 moves to the position of the trapezoidal card slot 203, the thrust received by the trapezoidal block 303 disappears. Under the action of the reset function of the spring 305, the spring 305 pushes the trapezoidal block 303 to move into the inside of the trapezoidal card slot 203 until the trapezoidal block 303 is engaged with the trapezoidal card slot 203, completing the installation work of a set of lead blocks 301;

[0038] Finally, move the end of the sealing side plate 204 to insert it into the inside of the square card slot 205, complete the closing work inside the mounting block 201, and finally complete the work.
