A rotating rod 2 is arranged on the upper side of the right surface of the workbench 1. A fixed plate 3 is fixedly connected to the left side of the rod wall of the rotating rod 2. The fixed plate 3 is used to fix one side of the wheel to prevent the wheel from being closely attached to the workbench 1, so that the wheel is not accurately tested due to friction problems during the test. A rotating cavity 4 is opened inside the rotating rod 2, and a fixing mechanism is arranged inside the rotating cavity 4.

[0023] The fixing mechanism includes a threaded rod 5, the rod wall of the threaded rod 5 is rotatably connected to the inner wall of the rotating cavity 4, a slide groove 6 is opened at the center of the rotating rod 2, and a threaded block 7 is slidably connected to the inner wall of the slide groove 6. The centers of both sides of the threaded block 7 are threadedly connected to the rod wall of the threaded rod 5, and the four sides of the right side surface of the threaded block 7 are rotatably connected to connecting rods 8. The other ends of the four connecting rods 8 are provided with cavities 9, and the inner walls of the four cavities 9 are slidably connected to support plates 10. The ends of the four connecting rods 8 away from the threaded blocks 7 all penetrate the lower side of the inner wall of the cavity 9 and extend to the bottom surface of the support plate 10. The four connecting rods 8 are away from the threaded blocks 7. One end of the threaded block 7 is rotatably connected to the bottom surface of the corresponding support plate 10 respectively, and a through hole is opened in the front and rear of the cavity 9 where the connecting rod 8 penetrates, so as to avoid the connecting rod 8 from getting stuck when rotating, thereby improving the stability of the structure. The center of the surface of the four support plates 10 away from the threaded rod 5 is fixedly connected with a support rod 11, and the two sides of the surface of the four support plates 10 away from the threaded rod 5 are fixedly connected with a spring 12. The spring 12 is provided to limit the support plate 10 and the fixing plate 13 to avoid the fixing plate 13 on the lower side and both sides from protruding under the action of gravity. When the wheel is placed on the rotating rod 2, it is difficult to place it because of the fixing plate 13. The other ends of the eight springs 12 are fixedly connected to the upper side of the inner wall of the corresponding cavity 9, and the ends of the four support rods 11 away from the threaded rod 5 are provided with a fixing plate 13. The ends of the four support rods 11 away from the threaded rod 5 respectively penetrate the upper side of the inner wall of the corresponding cavity 9 and extend to the bottom surface of the fixing plate 13.
