Preferably, the contour area on the horizontal projection surface is 1.05-1.15 times that of the insert 11 in the caster mounting groove 2.

Specifically, the outline area of the caster mounting groove 2 on the horizontal projection plane is slightly larger than the insert 11, and can be 1.05-1.15 times, so that the caster mounting groove can meet the limited shake of the caster 1 after being assembled in place, and the convenience in assembling and disassembling the caster 1 can be fully considered. Further, the outline areas of the caster mounting groove 2 and the insert 11 on the horizontal projection plane are rectangular.
