In some instances, known methods and structures are not described in detail to avoid making these embodiments unnecessarily difficult to understand. In addition, all embodiments can be used in combination with each other.

[0025] Example:

[0026] A universal automatic rebound special-shaped component clamping device comprises a semicircular clamping block 1, a plurality of through holes 2 are evenly distributed on the semicircular clamping block 1, a semicircular abutting pad 3 is fixedly connected to one side of the semicircular clamping block 1 with the through holes 2, the semicircular abutting pad 3 coincides with the side wall of the semicircular clamping block 1, a clamping spring 4 is fixedly connected in each through hole 2, an adapting fixing rod 5 is slidably connected in each through hole 2, each adapting fixing rod 5 is arranged through the semicircular abutting pad 3, each adapting fixing rod 5 is connected to the clamping spring 4 in the through hole 2, a clamping block 6 is fixedly connected to the side of the semicircular clamping block 1 away from the through hole 2, and a connecting groove 7 is provided on the side of the clamping block 6 away from the semicircular clamping block 1.

[0027] Through the above technical solution, when the bicycle needs to be repaired, the two universal automatic rebound special-shaped component clamping devices are clamped by aligning the connecting groove 7 on the clamping block 6 with the connecting head of the repair bracket, and then the bicycle is placed between the two universal automatic rebound special-shaped component clamping devices, and the distance between the two universal automatic rebound special-shaped component clamping devices is adjusted so that the clamping devices fit the position of the special-shaped component that needs to be fixed and clamped. At this time, the special-shaped component will squeeze the corresponding adapter fixing rod 5 to extend into the through hole 2, and the adapter fixing rod 5 that is not squeezed into the through hole 2 can be used around the special-shaped component to limit and clamp it in all directions, thereby facilitating the clamping and fixing of any bicycle and any shape thereof, thereby improving the maintenance efficiency.

[0028] One end of each adapter fixing rod 5 extending into the through hole 2 is fixedly connected with an anti-dropping limiting round block 8, which is slidably connected in the through hole 2 and abuts against the semicircular abutting pad 3. The two clamping devices are moved to separate the two clamping devices from the special-shaped parts. At this time, the adapter fixing rod 5 rebounds under the elastic force of the clamping spring 4 and returns to its original state. During the rebound process, the anti-dropping limiting round block 8 can abut against the semicircular abutting pad 3 to prevent the adapter fixing rod 5 from falling off, thereby improving the service life of the clamping device.

[0029] The semicircular abutment pad 3 is provided with a plurality of limiting holes 9 for the fitting fixing rod 5 to pass through, each fitting fixing rod 5 is slidably connected in the corresponding limiting hole 9, the diameter of the fitting fixing rod 5 is the same as the diameter of the corresponding limiting hole 9, the diameter of the anti-slip limiting round block 8 is the same as the diameter of the corresponding through hole 2, and the diameter of the fitting fixing rod 5 is smaller than the diameter of the anti-slip limiting round block 8. By setting the diameters of the limiting hole 9 and the through hole 2, the anti-slip limiting round block 8 can be limited in the through hole 2, thereby improving the stability of the fitting fixing rod 5 when it rebounds.

[0030] A fixing threaded hole 11 is provided on the semicircular clamping block 1, and a connecting bolt 10 is provided through the semicircular abutment pad 3, and the connecting bolt 10 is threadedly connected in the corresponding fixing threaded hole 11. By fixing the semicircular abutment pad 3 with the connecting bolt 10, the adapter fixing rod 5 and the clamping spring 4 can be easily replaced, the clamping device can be easily repaired, and the service life of the clamping device can be extended.

[0031] The side wall of the connection groove 7 is provided with an anti-skid ring groove 13, and an annular anti-skid pad 12 is fixedly arranged in the anti-skid ring groove 13. When the two clamping devices are connected to the connecting head of the corresponding maintenance bracket through the connection groove 7, the annular anti-skid pad 12 in the anti-skid ring groove 13 can increase the friction between the connecting head and the clamping device, improve the stability of the connection of the clamping device, and further improve the stability of the clamping device when clamping the special-shaped parts on the bicycle.

[0032] The end of the adapter fixing rod 5 away from the semicircular abutment pad 3 is set as an annular rounded corner 14. Setting the annular rounded corner 14 can prevent the adapter fixing rod 5 from wearing the special-shaped component when the adapter fixing rod 5 is pushed into the through hole 2 by the special-shaped component, and can also prevent the clamping device from scratching the bicycle, thereby improving the protection of the bicycle.

[0033] The universal automatic rebound special-shaped component clamping device, when in use, the two universal automatic rebound special-shaped component clamping devices are clamped by aligning the connection groove 7 on the clamping block 6 with the connection head of the maintenance bracket, and then the bicycle is placed between the two universal automatic rebound special-shaped component clamping devices, and the distance between the two universal automatic rebound special-shaped component clamping devices is adjusted so that the clamping devices fit the position of the special-shaped component that needs to be fixed and clamped. At this time, the special-shaped component will squeeze the corresponding adapter fixing rod 5 to extend into the through hole 2, and the adapter fixing rod 5 that is not squeezed into the through hole 2 can be clamped around the special-shaped component in an all-round limited manner, so as to facilitate the clamping and fixing of any bicycle and any form thereof, and improve the maintenance efficiency. When the inspection is completed, the two universal automatic rebound special-shaped component clamping devices are separated from the special-shaped component, and the pushed-in adapter fixing rod 5 rebounds under the action of the clamping spring 4 for continued use next time.
