A connecting groove is provided inside the cavity limiter 8, and a disassembly connector 9 is provided in the connecting groove of the cavity limiter 8. Limit hooks 901 are provided on both sides of the disassembly connector 9. A limiting step 801 is provided on the inner arc surface of the cavity limiter 8. A positioning branch 10 is provided at the bottom of the limiting disassembly connector 9. The positioning branch 10 penetrates into the cavity limiter 8. A compression spring 11 is connected to the lower surface of the positioning branch 10. There are two compression springs 11, which are distributed in a mirror-symmetrical manner. The disassembly connector 9 is an elastic structure. A rectangular groove 12 is provided on one side of the outer arc surface of the wheel frame 2. The inner arc surface of the rectangular groove 12 penetrates and fits with the disassembly connector 9. A shaft sleeve portion 13 is provided on both sides of the upper surface of the connector 7.
[0024] By pressing the disassembly connecting piece 9, the limit hooks 901 on both sides are released from contact with the limit step 801, so that the positioning branch 10 at the rear end controls the compression spring 11 in the pressing direction to cause it to deform.

The disassembly connecting member 9 is pressed to release the contact between the limit hooks 901 on both sides and the limit steps 801, so that the positioning branch 10 at the rear end controls the compression spring 11 in the pressing direction to deform it. When the limit hooks 901 are released from the limit between the limit steps 801, they can be removed. The opening of the elastic member 6 at the other end pulls the bottom end downward to offset the vertical angle and then releases the limit from the elastic latch tooth 701. Since the original elastic latch tooth 701 makes the movement overlap on the concave platform 601, when one end of the elastic member 6 is driven, the overlap with the elastic latch tooth 701 will be released, thereby completely removing the connector 7 and the roller 15 under the support leg member 14 as a whole, which makes it convenient to install and remove the universal wheel. The disassembly adopts the method of locking the two ends, so that when one of the locks falls off, the entire roller 15 will not be completely separated from the bag, so the bag can be used continuously.
