[0024] It is worth mentioning that a mounting groove 809 is provided at the bottom of the upper side plate of the T-shaped block 806, and a plurality of steel balls 810 are rotatably connected inside the mounting groove 809. The lower ends of the steel balls 810 extend into the interior of the limiting groove 7 and abut against the bottom surface of the interior of the limiting groove 7. The design of the steel balls 810 can reduce the friction between the T-shaped block 806 and the T-shaped groove 6, making the T-shaped block 806 move more smoothly to prevent the T-shaped block 806 from being unable to move. Reducing friction also means reducing energy loss during operation, thereby improving the operating efficiency and accuracy of the device.

[0025] Preferably, the clamping assembly 8 also includes a servo motor 802, which is fixedly installed in the middle position of the bottom of the substrate 1. The output end of the servo motor 802 passes through the bottom surface of the substrate 1 and is fixedly connected to a threaded rod 803. The surface of the threaded rod 803 is threadedly connected to a movable plate 801. The servo motor 802 provides precise displacement control and high power output, thereby ensuring the stability and accuracy of the clamping operation. The linkage design of the connecting rod 812 enables the multiple clamping rods 808 of the clamping assembly 8 to move synchronously, thereby improving the clamping efficiency.

[0026] Specifically, six fixing blocks 804 are fixedly connected to the upper surface of the movable plate 801 , and one side of the upper surface of the six fixing blocks 804 is fixedly connected to a first connecting ear 805 .

[0027] Specifically, one side of the first connecting ear 805 is rotatably connected to a connecting rod 812 , and one end of the connecting rod 812 away from the first connecting ear 805 is rotatably connected to a second connecting ear 811 , and the second connecting ear 811 is fixedly connected to the bottom of the connecting plate 807 .

[0028] Specifically, the adjustment component 2 includes a lifting sleeve 201, a lifting rod 203 is slidably connected inside the lifting sleeve 201, the upper end of the lifting rod 203 is fixedly connected to the bottom of the substrate 1, and a level foot 202 is fixedly connected to the bottom of the lifting sleeve 201. The design of the adjustment component 2 allows the user to adjust the height and levelness of the substrate 1 according to test needs, thereby ensuring the accuracy and repeatability of the test.

[0029] Preferably, a plurality of first pin holes 204 are formed through the surface of the lifting rod 203, and two groups of second pin holes 205 are formed on the upper end surface of the lifting sleeve 201. Fixed pins 206 are inserted into the first pin holes 204 and the second pin holes 205. By simply plugging the first pin holes 204, the second pin holes 205 and the fixed pins 206, the adjustment process is fast and stable.

[0030] Working principle: When in use, first adjust the levelness of the base plate 1 through the adjustment component 2 according to the site environment. The specific method is to pull out the lifting rod 203 from the lifting sleeve 201, and then adjust the position of the lifting rod 203 in the lifting sleeve 201 according to the needs, and select the appropriate first pin hole 204 and second pin hole 205, and fix it with a fixing pin 206. Then adjust the other adjustment components 2 in the above-mentioned manner, so as to adjust the levelness and height of the base plate 1. When clamping the tire, first place the tire through the positioning rod 5. It is placed on the placement plate 4, and then the output end of the servo motor 802 drives the threaded rod 803 to rotate, and the movable plate 801 is moved up and down through its internal thread. When the movable plate 801 moves downward, the connecting rod 812 is pulled by the fixed block 804 and the first connecting ear 805, so that the angle between the connecting rod 812 and the movable plate 801 becomes larger, so that the connecting plate 807 at the end of the connecting rod 812 drives the T-shaped block 806 to slide inside the T-shaped groove 6, and the tire is clamped through the clamping rod 808. Similarly, when the movable plate 801 moves upward, the clamping of the tire is released.
