The position of the upper guide plate 61 is adjusted in multiple directions. When the position of the plant is determined, it is necessary to limit multiple adjustment positions before the positioning guide needle operation can be stably performed; when the rotation angle of the turntable 72 is limited, the card plug rod 81 is first pulled to slide on the inner wall of the card plate 8, and the elastic member is pulled by force, and the bottom end of the card plug rod 81 leaves the circular hole, and the turntable 72 is rotated according to the position of the intertrochanteric fracture incision. After the rotation is completed, the card plug rod 81 is released, and the elastic force of the elastic member is reset to drive the card plug rod 81 to slide down the inner wall of the card plate 8, and the card plug rod 81 is inserted into another circular hole for plugging, which plays a role in limiting the rotation angle of the turntable 72;When the extension plate 6 slides on the short rod of the connecting plate 73 to adjust the longitudinal distance between the extension plate 6 and the extrusion plate 51, the fourth bolt 91 is first rotated in the opposite direction to reduce the friction force of the friction plate 9 pressing on the surface of the extension plate 6, and then the extension plate 6 is pulled to slide on the short rod to adjust the longitudinal distance between the extension plate 6 and the extrusion plate 51. After the adjustment is completed, the fourth bolt 91 is rotated forward, the fourth bolt 91 is threaded on the short rod, and the fourth bolt 91 presses the friction plate 9 downward, so that the friction plate 9 presses the extension plate 6 tightly on the connecting plate 73, thereby adjusting the limit position of the extension plate 6; When limiting the position of the patient's fractured limb, the No. 1 foot pedal 92 is fixed to the end of the No. 2 positioning rod 4 away from the No. 1 positioning rod 1, so that the patient's sole can fit tightly on the No. 1 foot pedal 92, and the heel and sole can fit on the two No. 2 foot pedals 94. The patient's foot is fixed on the No. 2 foot pedal 94 using straps passing through multiple strap grooves 95. The position of the connecting slider 93 is adjusted according to the position of the patient's leg, so that the patient's leg and foot remain vertical, thereby fixing and limiting the patient's foot.
