[0008] Preferably, two symmetrical rotating shaft limiting rods are bolted on the rotating shaft, and the rotating shaft limiting rods can be inserted into the notches at the rotating shaft of the turning handle to limit the rotation angle of the turning handle. When in use, the footrest is pulled to both sides so that the notch of the rotating shaft in the turning handle is out of contact with the rotating shaft limiting rods, so that the footrest can be rotated backward for storage; when the footrest slides inward so that the rotating shaft limiting rods are inserted into the notch of the rotating shaft in the turning handle, the footrest can be limited so that the footrest can support the weight of the legs.
[0009] Preferably, a footrest cover is bolted to the lower end surface of the footrest, thereby sealing the outer end of the handle to improve appearance and safety.

Such a structural design of the telescopic rod can enable its front end to maintain good straightness when it has a certain weight and avoid bending, so that the telescopic rod can extend and retract more smoothly in the pull-out groove.
[0011] Preferably, the maximum rotational travel angle of the footrest does not exceed two hundred and seventy degrees.
[0012] The advantages and positive effects of the utility model are as follows: after the telescopic rod is pulled out, the footrest originally in the storage state is pulled apart to both sides, then reversed upward and pushed inward, so that the notch of the rotating shaft in the turning handle is inserted into the limiting rod of the rotating shaft to realize the supporting limited state, so that it can be used to support the foot; on the contrary, when storing, the footrest is pulled apart to both sides to make it out of the limited state, then reversed backward to make it stored to the lower side of the telescopic rod, and then the telescopic rod is pushed backward so that the footrest is stored to the lower side of the seat.

[0022] Preferably, the rotating shaft 19 is rotatably arranged in the rotating base 12, and a slot for inserting the end of the telescopic rod 16 is provided at the tail end of the rotating base 12, the rotating base 12 is inserted and fixed to the end of the telescopic rod 16, and the rotating base bottom shell 18 is covered with bolts on the lower end surface opening of the rotating base 12.
[0023] Preferably, a rotating shaft 19 is fixedly provided at the front end of the telescopic rod 16, and the footrest 10 is symmetrically rotated on the rotating shaft 19. A rotating handle 21 slidably inserted on the rotating shaft 19 is provided on the side of the footrest 10, so that the footrest 10 can rotate relative to the rotating shaft 19 under the action of the rotating handle 21.
[0024] Preferably, two symmetrical rotating shaft limiting rods 20 are bolted to the rotating shaft 19, and the rotating shaft limiting rods 20 can be inserted into the notches at the rotating shaft of the turning handle 21 to limit the rotation angle of the turning handle 21. When in use, the footrest 10 is pulled to both sides so that the notch of the rotating shaft in the turning handle 21 is out of contact with the rotating shaft limiting rods 20, so that the footrest 10 can be rotated backward for storage, and when the footrest 10 slides inward so that the rotating shaft limiting rods 20 are inserted into the notch of the rotating shaft in the turning handle 21, the footrest 10 can be limited, so that the footrest 10 can support the weight of the legs.
[0025] Preferably, a footrest cover 11 is bolted to the lower end surface of the footrest 10, thereby sealing the outer end of the handle 21 to improve the appearance and safety.
[0026] Preferably, the cross-section of the telescopic rod 16 is arched, and the pull-out groove 15 is similar in shape to the telescopic rod 16. The telescopic rod 16 is slidably inserted into the pull-out groove 15.
