[0008] The fixing assembly is arranged on the upper part of the sliding assembly, and the fixing assembly includes a fixing block and a clamping block rotatably connected to the fixing block.

[0009] Furthermore, the upper part of the fixing block is provided with left-right symmetrical fixing ears and a groove provided near the fixing ears, the two sides of the clamping block are connected with a rotating shaft inserted into the fixing ears, and the clamping block has a limiting end, which deflects in the groove.

[0010] Furthermore, a spring is provided at the limiting end of the clamping block.

[0011] Furthermore, the sliding assembly includes a slider and a slide bar, the slider is arranged in the slide groove, and the slide bar is arranged on the upper part of the placement platform and connected to the slider.

[0012] Furthermore, the telescopic end of the hydraulic rod is provided with a connecting piece, and the connecting piece is fixedly connected to the sliding block.

[0013] The technical effects and advantages of this utility model are:

[0014] The utility model is provided with a fixing assembly on the sliding assembly, and the fixing assembly includes a rotatable clamping block, which has a limiting end and is deflected in the limiting end and the groove, and is limited by the cooperation between the groove and the limiting end. When in use, the clamping block is made to move vertically upward by a spring provided in the groove, and the hydraulic rod drives the entire clamping block to clamp and fix the rim to press the tire. When the tire is pressed in, the clamping block releases the rim. During the release process, the clamping block is deflected by force to avoid hard contact between the clamping block and the tire, thereby preventing the tire from being scratched.
