[0035] Optionally, the connecting rod 4 can also be provided with two.

[0036] Optionally, as a possible implementation, the bottom of the receiving cavity 21 can also be provided with a connecting plate, each connecting plate is provided with a plurality of through holes through which the positioning members 3 pass, and a stop structure is further provided on the part of the positioning members 3 inside the receiving cavity 21, so that after the pull body 2 is pulled out, the positioning members 3 can pass through the through holes.

[0037] As shown in Figure 3 , as an implementation, the positioning member 3 is provided with a sliding slot, the connecting rod 4 passes through the sliding slot, the sliding slot includes a first slot 31 in the vertical direction, the positioning block moves up and down along the first slot 31 through the connecting rod 4, and the sliding slot further includes a second slot 32 in communication with the first slot 31, the second slot 32 is arranged in the horizontal direction, i.e. the sliding slot is a T-shaped slot, the width of the second slot 32 is matched with the diameter of the connecting rod 4, and since the second slot 32 is perpendicular to the first slot 31, when the positioning block slides to the uppermost end of the first slot 31, the positioning block is shifted leftward or rightward relative to the connecting rod 4 by being poked, the connecting rod 4 is embedded in the second slot 32, and the positioning block is prevented from shaking in the vertical direction, so as to improve the stability between the positioning block and the pull body 2.

[0038] Optionally, as a possible implementation, when the positioning block slides to the uppermost end of the first groove 31, the positioning block can also be moved in the direction of the second groove 32 by means of motor driving.

[0039] As shown in Figure 4 , as an implementation, the pull body 2 is also provided with a through area 22 for accommodating the cushion 5, thereby improving the space utilization of the lower limb support cushion, and the cushion 5 is hidden in the cavity 111 in the state that the pull body 2 is not pulled, and does not additionally occupy space.

[0040] As shown in Figure 3 and 4 , as an implementation, the lower limb support cushion further comprises at least one cushion 5, which is detachably connected with the upper end face of the pull body 2, so that when the pull body 2 is pulled out, the cushion 5 in the through area 22 can be taken out and fixed on the upper end face of the pull body 2, and is opposite to the second circular surface 14, thereby supporting the lower limbs of the patient, and meeting the use requirements of patients of different heights.

[0041] Optionally, the cushion 5 and the upper end face of the pull body 2 can be connected by magic tape or snap fastener.

[0042] Optionally, the cushion 5 is made of flexible material, which can be foam or silica gel.

[0045] As an implementation, the thickness of the cushion 5 is not less than the distance from the upper end face of the support body 1 to the upper end face of the pull body 2, so that the part of the cushion 5 can be prevented from being lower than the upper end face of the support body 1, and the blood circulation of the lower limbs of the patient is facilitated.

[0046] If the cushion 5 is located on the upper end face of the pull body 2, the highest position is lower than the upper end face of the support body 1, at this time, the lower limbs of the patient are placed on the second circular surface 14 and the third circular surface 51, and the calf part of the patient is lower than the thigh part, which is easy to cause the blood to be not smooth.

[0047] As an implementation, one side of the pull body 2 is also provided with a scale mark, so that medical staff can intuitively see the length of the pull body 2 pulled out.

[0048] Optionally, as a possible implementation, the puller 2 can be further provided with a digital display screen to display the length of the puller 2 being pulled out.
