[0012] As a further technical solution of this utility model, the support sleeve is movably connected to the threaded rod, the bolt head is fixedly connected to the threaded rod, and the positioning block is movably connected to the bolt head.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the high-strength main shaft structure of this scooter not only improves the overall strength and enables quick assembly and disassembly, but also enables quick replacement of connecting parts;

[0014] By setting a fixed sleeve, a connecting tube, and reinforcing ribs, a fixed sleeve is fixed on one side of the connector of the spindle. After the connecting tube is installed, the fixed sleeve fits against the outside of the connecting tube, which can effectively support the connecting tube and improve the stability of the connection between the connecting tube and the connector. Furthermore, the reinforcing ribs at both ends of the fixed sleeve are connected to the connector, which can improve the strength of the fixed sleeve, thereby improving the supporting force on the connecting tube and improving the overall strength of the spindle structure.

[0015] The spindle is equipped with a fixed sleeve, a threaded sleeve, a connecting tube, a mounting bolt, a fixing plate, and a through hole. When installing the spindle, the connecting tube is inserted into the fixed sleeve, and then the mounting bolt is inserted into the connecting tube. The mounting bolt passes through the through hole and is then inserted into the threaded sleeve. The mounting bolt is then rotated to make it enter the threaded sleeve, and tightened to fit against one side of the fixing plate. The fixing plate positions the connecting tube. When disassembling, the mounting bolt can be rotated to disengage it from the threaded sleeve, and then the connecting tube can be removed from one side of the connector. This allows for quick assembly and disassembly of the spindle.

[0016] By incorporating a hexagonal groove, positioning block, bolt head, support sleeve, threaded rod, groove, and spring, this spindle can quickly replace the threaded rod if it is damaged due to the movement of a scooter after installation. Pressing two sets of springs causes the positioning block to disengage from the top of the bolt head.
