[0025] In a preferred embodiment, the first support assembly includes two parallel bent rods 3; the bent rod 3 includes a first support rod 31, and a second support rod 32 is fixedly disposed at one end of the first support rod 31, and the included angle between the first support rod 31 and the second support rod 32 is set to between 120° and 150°.
[0026] Preferably, the included angle between the first support rod 31 and the second support rod 32 on a bent rod 3 is set to 150°.
[0027] In a preferred embodiment, two sets of hinge components are provided, and the two sets of hinge components are correspondingly arranged with the two bent rods 3. The hinge component includes a U-shaped plate 4 fixedly arranged on the bottom beam 2 of the main frame 1, and a rotating shaft 5 is rotatably arranged inside the U-shaped plate 4. The end of the first support rod 31 on the same bent rod 3 away from the second support rod 32 is fixedly connected to the outer circumferential wall of the corresponding rotating shaft 5, thereby realizing the function of the bent rod 3 rotating with the rotating shaft 5.
[0028] In a preferred embodiment, the connecting assembly includes two parallel connecting rods 6, and two parallel fixing rods 7 are fixedly disposed between the two connecting rods 6; the length direction of the fixing rods 7 is perpendicular to the length direction of the connecting rods 6; the two fixing rods 7 are respectively fixedly disposed at the ends of the two second support rods 32 away from the corresponding first support rods 31.
[0029] That is, the two fixed rods 7 and the two connecting rods 6 form a rectangular connecting frame, which is used to install the foot pedal 8 on the two bent rods 3.
[0030] In a preferred embodiment, the second support assembly includes a diagonal brace 9, one end of which is fixedly mounted on a second support rod 32 located on the inner side.
