Connecting seat 21 detachable connects on 1 side of operation table, is the joint formula in the 21 this schemes of connecting seat, through being equipped with in connection 21 inboards and taking elastic latch device. The connecting seat 21 is provided with a connecting hole matched with the connecting end of the fixed rod 22, the fixed rod 22 and the connecting hole are internally provided with a tooth-shaped groove, the fixed rod 22 can rotate relative to the connecting seat 21, the rotating angle is a tooth shape at each time, and the rotating amount of the fixed rod 22 can be controlled. One end of the fixing rod 22 is connected with the connecting seat 21, the other end of the fixing rod is connected with the supporting rod 23, the supporting rod 23 rotates relative to the fixing rod 22, the connecting end of the supporting rod 23 and the fixing rod 22 is close to one end of the supporting rod 23, and the wire take-up device 3 is arranged in the end, far away from the connecting end of the fixing rod 22, of the supporting rod 23. The auxiliary tool 4 is connected with one end of the take-up device 3.

Specifically, an accommodating cavity for installing the wire take-up device 3 is arranged in the support rod 23. The wire takeup device 3 includes a pressing member 31, a brake member 32, a winding shaft 33, a rotating gear 34 and a traction wire 37. The pressing member 31 penetrates through one end of the support rod 23 and is located at the upper part of the support rod 23, the other end of the pressing member 31 is located at the upper part of the braking member 32 and is located in the accommodating cavity of the support rod 23, one end of the braking member 32 located in the accommodating cavity of the support rod 23 is connected with the braking member 32, the braking member 32 is fixed on the inner wall of the support rod 23 through a fixed shaft, and the tooth-shaped end is buckled with the rotating gear 34, so that the rotating gear 34 can only rotate in one direction. The engagement and disengagement of the stopper 32 with and from the rotary gear 34 can be driven by the pressing of the pressing member 31. When the pressing member 31 is pressed, the connecting shaft of the stopper 32 is positioned between the toothed end of the stopper 32 and the connecting end of the pressing member 31, and the toothed end is separated from the rotating gear 34 according to the principle of leverage. In order to eliminate the external force applied on the pressing member 31, the braking member 32 is continuously engaged with the rotating gear 34, a torsion spring 36 is mounted on the fixed shaft of the braking member 32, one end of the torsion spring 36 is fixed on the inner wall of the accommodating chamber, and the other end is located at the connecting end of the braking member 32 and the pressing member 31.
