During the process of inserting the protrusions 22 into the installation cavity 11, the protrusions 22 can push the latch 4 to move in the direction of compressing the reset spring 5, so that the protrusions 22 are smoothly inserted into the bottom end of the installation cavity 11. Then manually rotate the rotating chuck 21 so that its protrusions 22 are embedded in the corresponding slot positioning parts 122, and its locking latch hole 23 corresponds to the positioning through hole 14. Under the elastic action of the reset spring 5, the latch 4 is automatically inserted into the locking latch hole 23 through the lock wheel push button switch 3. The latch 4 can limit the rotating chuck 21 to limit its rotation, and the installation is completed.

[0048] When disassembling, it is only necessary to manually push the lock wheel push button switch 4 to move in the direction of compressing the return spring 5, and drive the pin 4 to be pulled out from the locking pin hole 23, and manually rotate the rotating chuck 21 in the opposite direction to make its locking protrusion 22 withdraw from the locking slot locking portion 122 and return to the notch insertion portion 121. At this time, the rotating chuck 21 can be downwardly disengaged from the moving wheel insertion seat 1, so that the moving wheel body 2 is completely pulled out from the moving wheel insertion seat 1, and the disassembly is completed, so that the moving wheel body 2 can be replaced or repaired.

[0049] In summary, the movable wheel body of the utility model can be rotatably connected with the movable wheel insert seat through the rotating chuck, and its installation and disassembly are very fast, and the assembly efficiency is high, which can facilitate subsequent replacement or maintenance, and there is no need to replace the luggage as a whole, which effectively extends the service life of the luggage and greatly improves the practicality. In addition, the lock wheel push button switch and the latch of the utility model are designed in a split type. When the latch is damaged, only the latch needs to be replaced, and the maintenance cost is low.
