[0034] In this embodiment, the grooves 19 are designed in a straight long strip shape inside the pedal 16 and the support plate 15. By providing the grooves 19, the dust on the patient's foot pads can easily fall from the pedal 16, preventing dust from accumulating on the pedal 16.
[0035] Working principle and usage process of the utility model: First, when a patient comes by wheelchair for gluteal muscle injection, since the patient has limited mobility, it is very difficult to move to a stool for injection. At this time, the guardrails 8 on both sides of the wheelchair need to be disassembled to facilitate medical staff to directly inject the patient on the wheelchair. First, loosen the second nut 18 so that it no longer fits tightly with the second assembly rod 6, and then pull down the sliding rod 11, which drives the limit ring 10 to slide downward and controls the top of the limit ring 10 to be completely hidden inside the second assembly rod 6. At this time, the guardrail 8 can be pulled to remove the guardrail 8 from inside the first assembly rod 5 and the second assembly rod 6, quickly achieving the effect of disassembling the guardrail 8. After the injection is completed, insert the guardrail 8 back into the first assembly rod 5 and the slot 7, and control the limit ring 10 to move upward so that the limit ring 10 fits tightly with the guardrail 8. Finally, tighten the second nut 18 to quickly assemble the guardrail 8.
[0036] When the patient's feet are placed on the pedal 16 and the height of the pedal 16 needs to be adjusted, the two sets of second nuts 18 can be rotated away from the support plate 15, and then the vertical rod 17 can be slid up and down to adjust the height of the pedal 16. After the adjustment is completed, the two sets of second nuts 18 are screwed again to fit tightly with the support plate 15 to limit the pedal 16. By setting the groove 19, the groove 19 can facilitate the dust on the patient's foot pad to fall off the pedal 16, preventing dust from accumulating on the pedal 16.
[0037] The above are only the preferred embodiments of the utility model and are not intended to limit the utility model.
