An installation cavity 6 is arranged inside the base 1. The positioning frame 3 is fixed on the top of the base 1. A plurality of vertical plates 31 are fixedly arranged at the upper end of the positioning frame 3, and the plurality of vertical plates 31 are circumferentially arrayed with the axis of the positioning frame 3 as the center. The clamping assembly 4 includes a support column 42, a guide plate 41, a spring 44 and a plurality of transmission plates 43. The guide plate 41 is fixed at the bottom of the support column 42. A guide hole adapted to the guide plate 41 is arranged on the base 1, and the guide hole communicates with the installation cavity 6. The support column 42 is placed in the upper part of the base 1. The guide plate 41 is slidably inserted into the guide hole, and the lower end extends downward into the installation cavity 6, so that the support column 42 can move up and down along the axis direction of the base 1. The spring 44 is placed in the installation cavity 6, the upper end is fixedly connected with the support column 42, and the lower end is fixedly connected with the base 1, so that the support column 42 is reset by the spring 44. The plurality of transmission plates 43 are circumferentially arrayed with the axis of the support column 42 as the center, and are arranged corresponding to the vertical plates 31. The number of the transmission plates 43 corresponds to the number of the vertical plates 31, and each transmission plate 43 corresponds to one vertical plate 31. A plurality of connecting lugs are fixedly arranged on the support column 42, and the plurality of connecting lugs are circumferentially arrayed with the axis of the support column 42 as the center. One end of the transmission plate 43 is hinged to the connecting lug on the support column 42, and the other end is provided with a limiting long hole 431. A limiting rod is fixedly arranged on the vertical plate 31, and the limiting rod is slidably inserted into the limiting long hole 431. When the support column 42 moves upward, it will push one end of the transmission plate 43 upward, and the other end moves away from the axis of the support column 42 under the restriction of the limiting rod and the limiting long hole 431. The adjustment structure includes a motor 21, a screw rod 22, a bearing seat 23 and a slider 24. The motor 21 and the bearing seat 23 are fixed on the base 1. The motor 21 is located outside the base 1, and the bearing seat 23 is located in the installation cavity 6 of the base 1. The screw rod 22, the bearing seat 23 and the slider 24 are placed inside the installation cavity 6. The screw rod 22 is installed on the bearing seat 23, and one end is in transmission connection with the motor 21. When the motor 21 is started, it can drive the screw rod 22 to rotate. The slider 24 is slidably installed on the base 1. A screw hole adapted to the screw rod 22 is arranged on the slider 24, and the screw rod 22 penetrates through the screw hole. The screw rod 22 is in threaded transmission with the screw hole. When the screw rod 22 rotates, the slider 24 can move along the axis direction of the screw rod 22 on the screw rod 22. A first guiding inclined surface is arranged at the lower part of the guide plate 41. A second guiding inclined surface matched with the first guiding inclined surface is arranged at the upper part of the slider 24, and the first guiding inclined surface and the second guiding inclined surface are in sliding friction contact. When the slider 24 moves towards the axis direction of the base 1, the first guiding inclined surface is pushed upward by the second guiding inclined surface, so as to make the guide plate 41 move upward. When the slider 24 moves away from the axis direction of the base 1, the support column 42 is pulled back to its original position by the spring 44.

[0025] In this embodiment, a guide rail 5 is fixedly provided inside the base 1. The guide rail 5 is arranged below the screw 22 along the axial direction of the screw 22 and is fixedly connected to the base 1. A guide groove matching the guide is provided on the slider 24, and the slider 24 can be slidably installed on the guide rail 5 through the guide groove.

[0026] In this embodiment, two guide plates 41 are configured and symmetrically arranged on both sides of the bottom of the support column 42; two sliders 24 are configured corresponding to the guide plates 41; two threads with opposite rotation directions are arranged on the screw rod 22, and the two sliders 24 are installed on the corresponding two sections of the thread. When the screw rod 22 rotates, the two sliders 24 are driven to move in the direction close to the axis of the base 1, and the two sliders 24 squeeze the two guide plates 41 upward, so that the support column 42 rises smoothly.

[0027] In this embodiment, a bending portion 433 is integrally provided on one end of the transmission plate 43 away from the support column 42 ; and the limiting long hole 431 is provided on the bending portion 433 .

[0028] In this embodiment, a protective rubber sleeve 432 is fixedly provided on one end of the bending portion 433 away from the support column 42. The protective rubber sleeve 432 is in extrusion contact with the inner side of the wheel hub to increase friction and prevent the wheel from being scratched.

[0029] Working principle:

[0030] When the motor 21 is started, it drives the screw 22 to rotate, causing the slider 24 to move along the axis of the screw 22. The second guide slope of the slider 24 pushes the first guide slope, causing the guide plate 41 to drive the support column 42 to move upward, thereby pushing the transmission plate 43 to move away from the axis of the support column 42. The axis of the support column 42 coincides with the axis of the wheel, and multiple transmission plates 43 expand outward at the same time to support the inner side of the wheel to position and clamp the wheel. The support column 42 can be driven to reset by the spring 44.
