A walking wheel body 5 is arranged on the walking wheel support 3. A wheel axle 4 is arranged between the walking wheel body 5 and the walking wheel support 3. The walking wheel body 5 and the walking wheel support 3 are rotatably connected through the wheel axle 4, which can ensure that the walking wheel body 5 can flexibly rotate along the wheel axle 4, thereby reducing the friction of the walking wheel body 5 when walking.

[0025] like Figure 1 , Figure 2 and Figure 5 As shown, a connecting rod 6 is arranged between the wheel axles 4, a fixing sleeve 7 is arranged on the periphery of the joint portion between the connecting rod 6 and the wheel axle 4, a mounting hole 9 is formed inside the fixing sleeve 7, a fixing screw 8 is arranged on the outer wall of the fixing sleeve 7 at one end of the wheel axle 4, the fixing screw 8 is connected to the fixing sleeve 7 by threads, both ends of the connecting rod 6 are located inside the fixing sleeve 7 and fixedly connected to a limit turntable 10, and the connecting rod 6 and the fixing sleeve 7 are rotatably connected by the limit turntable 10.

[0026] In this example, the limit turntable 10 can move inside the fixed sleeve 7. At the same time, the fixed sleeve 7 and the wheel axle 4 can be separated by loosening the fixing screw 8 and sliding the fixed sleeve 7 toward the side of the connecting rod 6, making it convenient to disassemble and replace the walking wheel body 5.

[0027] like Figure 1-Figure 4As shown, the walking wheel body 5 includes a walking wheel base 502, a walking sleeve 501 arranged on the periphery of the walking wheel base 502, and a keyway hole 503 opened inside the walking wheel base 502.
