Specifically, through set up guide groove 711 on the second grade body of rod 71, set up guide block 611 on the first grade body of rod 61 for first grade lead screw 63 is at the pivoted in-process, under the interact of guide block 611 and guide groove 711, guarantees that the second grade body of rod 71 removes along the length direction of the first grade body of rod 61, realizes stretching out and drawing back, and simple structure uses reliably, and the cost of manufacture is low.

In one embodiment, as shown in fig. 8, 10 and 14, the tertiary bar group 80 includes a tertiary bar body 81 and a movable sleeve 82, the movable sleeve 82 is installed in the secondary bar body 71 and is in threaded connection with the secondary screw rod 73, one end of the tertiary bar body 81 is connected with the movable sleeve 82, a guide body 712 extending along the length direction of the secondary screw rod 73 is arranged on the inner wall of the secondary screw rod 73, a limiting groove 821 is arranged on the periphery of the movable sleeve 82, and the guide body 712 is clamped in the limiting groove 821 to guide the movable sleeve 82 to move in the secondary screw rod 73. Specifically, because the movable sleeve body is in threaded connection with the second-stage lead screw 7323, and under the guidance of the guide body 712211 and the limiting groove 821321, when the second-stage lead screw 73 rotates, the movable sleeve body can be driven to move in the second-stage rod body 71, that is, the third-stage rod body 81 stretches relative to the second-stage rod body 71, so that the first-stage rod body 61 can drive the second-stage rod body 71 and the third-stage rod body 81 to stretch simultaneously, and the stretching efficiency is greatly improved. Further, be equipped with in the tertiary body of rod 81 and be used for dodging the second of second grade lead screw 73 and dodge groove 83, and the axis of second grade lead screw 73, the axis of the tertiary body of rod 81 and the axis that the groove 83 was dodged to the second are all on same straight line, and at the in-process of relative flexible between second grade lead screw 73 and the tertiary body of rod 81, through making second grade lead screw 73 directly insert and locate the tertiary body of rod 81, can greatly reduce lift support piece 50's whole volume, and the suitability is fabulous.

In one embodiment, as shown in fig. 13, a guide groove 711 is provided on the guide body 712. Specifically, through directly locating guide groove 711 on director 712, guide groove 711 protrudes in the inboard side of second grade body of rod 71 when being concave downwards towards the inboard of second grade body of rod 71 promptly, so not only make the outside of guide groove 711 can with the guide block 611 joint, the inboard of guide groove 711 forms director 712 and also can with spacing recess 821 joint, the transmission structure of lifting support piece 50 has greatly been simplified, avoid setting up the slide rail direction in the body of rod at all levels, simple structure and small and exquisite, the cost of manufacture is low.

In one embodiment, the first folding driving member 22 and the second folding driving member 24 can also adopt the lifting supporting member 50 of the embodiment of the present invention as a driving member to improve the response efficiency of the driving, so as to greatly improve the folding efficiency of the first folding plate 21 and the second folding plate 23, and give the patient a good use feeling.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
