In addition, as shown in fig. 6, the positioning block 55 is provided with a plurality of first ribs 556 arranged along the sliding groove direction of the second sliding groove 521 on the end surface of the attaching foot pad body 52, so as to reduce the contact area between the positioning block 55 and the foot pad body 52, and make the sliding more smooth. In the present embodiment, the bayonet provided at the outer end of the holder rod 51 is formed by abutting the two unit blocks 554, and the shape of the bayonet is matched with the bayonet provided at the inner end of the holder rod 51.

Example 2: the difference between the embodiment 2 and the embodiment 1 lies in the difference between the connection between the foot pad body and the bracket rod, which is as follows:

the foot pad body 52 is arranged on the outer end part of the support rod 51, specifically, the foot pad body 52 is hinged to the upper end of the outer end part of the support rod 51 through a connecting piece 6 arranged in the vertical direction, and a positioning station is arranged at the bottom of the foot pad body 52, so that the foot pad body 52 is relatively fixed at the starting end and the tail end of a rotating path. The foot pad body 52 horizontally rotates relative to the outer end portion to further achieve the unfolding of the foot pad body 52, and compared with the technical scheme of the embodiment 1, the operation is simple and fast. Wherein, the connecting piece 6 is a bolt or a screw.

The positioning stations are a boss 63 formed by surrounding the hinged part of the foot pad body 52 at the bottom of the foot pad body 52 and a clamping boss 61 formed by surrounding the boss 63; when the foot pad body 52 is unfolded, the outer end part of the foot pad body 52 is abutted against the boss 63 and limited by the clamping boss 61; an elastic positioning block 62 is further installed at the bottom of the foot pad body 52, and a first groove 64 matched with the elastic positioning block 62 is formed above the outer end of the bracket rod 51. When the foot pad body is in an unfolded state, the upper surface of the outer end part of the support rod is abutted against the bottom surface of the boss on the foot pad body, and meanwhile small-amplitude up-and-down swinging can be carried out in the space surrounded by the clamping bosses. In addition, the elastic positioning block is matched with the first groove to realize the positioning of the unfolding state of the foot pad body, so that the foot pad body is prevented from rotating.

Preferably, the footbed body 52 includes a base 561 and a panel 562 fixed above the base 561, a through hole 563 is opened on the base 561, the connecting member 6 passes through the through hole 563, and a gap exists between the through hole 563 and the connecting member 6. Therefore, the foot pad body can swing up and down. Meanwhile, the upper part of the base 561 is provided with a second groove 564 communicated with the through hole 563, the second groove 564 is embedded with a swinging block 565, the upper end of the connecting piece 6 is fixedly connected with the swinging block 565, and a space exists between the upper end of the swinging block 565 and the bottom of the panel 562; the oscillating piece 565 forms an arc surface with the second groove 564 so that the oscillating piece 565 can oscillate back and forth in the second groove 564. In this manner, the connection of the connector 6 to the base 561 can be strengthened; meanwhile, the swinging block 565 swings in the second groove 564, so that the swinging of the foot pad body can be smoother.
