The front end of the disassembly buckle 3 is formed with two fork blocks 31 matching the ring groove 21, and the rear end of the disassembly buckle 3 is bent to form a force block 32. A slot 412 is provided on the side wall of the wheel fork 41 for the disassembly buckle 3 to be plugged in and out. The slot 412 is connected to the mounting groove 411, and the part of the slot 412 located inside the force block 32 forms a force space 4121 for a finger to enter; when the first rivet 2 is connected to the wheel fork 41, the two insertion blocks are located in the ring groove 21 on both sides and abut against the bottom wall of the ring groove 21.

[0035] Reference Figure 1-Figure 3 When installing the caster body 4, first insert the bottom end of the first rivet 2 into the installation groove 411, then insert the disassembly buckle 3 into the slot 412, so that the two insert blocks of the disassembly buckle 3 enter the annular groove 21 to limit the first rivet 2, completing the quick connection between the first rivet 2 and the fork 41. When disassembling the caster body 4, the operator inserts a finger into the force application space 4121, applies force to the inner side of the force application block 32, pulls the disassembly buckle 3 out of the slot 412, and then pulls the first rivet 2 out of the installation groove 411, which can conveniently achieve disassembly and assembly of the caster body 4.

[0036] Reference Figure 1-Figure 3 The caster body 4 includes a fork 41, an elastic member 42, a movable block 43, a rotation limiting member 44, and two wheel bodies 5. One end of the movable block 43 is connected to a third rivet 433, and the movable block 43 is rotatably connected to the fork 41 through the third rivet 433. The rotation limiting member 44 is a second rivet 441, which is fixedly set on the fork 41. The second rivet 441 is located on the rotation path of the other end of the movable block 43. The second rivet 441 is always located below the corresponding end of the movable block 43 and is located below the third rivet 433. The elastic member 42 is set in the fork 41 and is used to drive the movable block 43 to rotate downward until it abuts against the second rivet 441. The two wheel bodies 5 are respectively located on both sides of the fork 41, and the wheel bodies 5 are rotatably connected to the movable block 43.

[0037] Reference Figure 1-Figure 3 The movable block 43 can swing in the wheel fork 41, and cooperate with the elastic member 42 to achieve a shock absorption effect.

[0038] Reference Figure 1-Figure 3 The elastic member 42 is a spring 421. A first limiting groove 413 is defined on the inner wall of the wheel fork 41 along the axis of the first rivet 2, which matches the spring 421. The top of the spring 421 is located in the first limiting groove 413, and the bottom of the spring 421 abuts against the movable block 43. The movable block 43 has a second limiting groove 431 defined on it, which matches the spring 421. The bottom of the spring 421 is located in the second limiting groove 431. A limiting protrusion 432 is defined on the bottom wall of the second limiting groove 431, and the limiting protrusion 432 is located inside the spring 421.

[0039] Reference Figure 1-Figure 3 The first limiting groove 413 can limit the top end of the spring 421, and the second limiting groove 431 can limit the bottom end of the spring 421.
