The accommodating groove 331 is used for clamping the end part of the axle, so as to realize more stable support of the axle. Specifically, the support platform 33 includes two inclined plates 332, the two inclined plates 332 are disposed at an angle with respect to the vertical direction, and the two inclined plates 332 are disposed opposite to each other to form a receiving groove 331. One end of a sloping plate 332 is fixedly connected to the connecting beam 32, and the other end is fixedly connected to a supporting frame 34. One end of the other inclined plate 332 is fixedly connected to the connecting beam 32, and the other end is fixedly connected to the other support frame 34. And two connection points formed by connecting the two inclined plates 332 with the connection beams 32, respectively, may be spaced apart from each other by a certain distance.

When the end of the axle is placed in the accommodating groove 331, the two circumferential sides of the end of the axle are correspondingly abutted against the two inclined plates 332. Under the action of gravity, the axle can be better clamped in the accommodating groove 331 formed by the two inclined plates 332, so that the supporting table 33 can better stably support the axle, and the axle is not easy to move up and down.
