[0022] Furthermore, connecting bolts 9 are fixedly provided at the top and bottom ends of the hub body 1, wherein the connecting bolts 9 facilitate the user to install the hub body 1 on the bicycle frame.

[0023] Furthermore, there are a plurality of spoke mounting grooves 3, and every two spoke mounting grooves 3 are designed to be equidistant from each other, wherein the spoke mounting grooves 3 are convenient for users to install and limit the spokes.

[0024] Furthermore, the spoke mounting groove 3 adopts a through-type design, and the spoke mounting groove 3 adopts a circular design, wherein this design facilitates the insertion of the spokes.

[0025] Furthermore, a number of supporting rubber pads 6 are provided, the supporting rubber pads 6 are fixedly connected to the second rubber ring 5, and every two supporting rubber pads 6 are designed to be equidistant from each other, wherein the supporting rubber pads 6 play a role of elastic support, so that the second rubber ring 5 and the first rubber ring 4 are connected together.

[0026] Furthermore, one end of the elastic arch support 7 away from the supporting rubber pad 6 is fixedly connected to the inner wall of the first rubber ring 4, and the elastic arch support 7 and the supporting rubber pad 6 are designed in a one-to-one correspondence.

[0027] Furthermore, both ends of the latex shock-absorbing strip 8 are fixedly connected to the inner wall of the elastic arch support 7, wherein the latex shock-absorbing strip 8 can play a shock-absorbing role.

[0028] Working principle: When using this device, an elastic connection is formed in the spoke mounting groove 3 through the setting of the first rubber ring 4 and the second rubber ring 5. The first rubber ring 4 can reduce the wear of the spoke mounting groove 3. The second rubber ring 5 is used to plug into the spoke, which can reduce the wear of the spoke, and the size of the second rubber ring 5 is designed to be slightly smaller than the size of the spoke, so that after the spoke is plugged into the second rubber ring 5, the second rubber ring 5 can fit tightly with the spoke, and the first rubber ring 4 and the second rubber ring 5 are connected together through the setting of the supporting rubber pad 6 and can withstand the force applied by the spoke. When the spoke applies force, the pressure will drive the supporting rubber pad 6 to deform and squeeze the elastic arch support 7. After being squeezed, the elastic arch support 7 will be deformed and drive the latex shock-absorbing strip 8 to buffer and absorb the vibration, and the supporting rubber pad 6 and the elastic arch support 7 will reduce the force when they are deformed, thereby reducing the damage to the device caused by the impact.

[0029] According to the above working process, we can know:
