The bottom of each edge be respectively arranged with sliding slot, sliding block is provided in the sliding slot, the drag hook plate is separately positioned on traction frame
In each edge of body, the fastener is separately positioned on drag hook plate and is connected with sliding block, the fastener include torq,
Screw rod and limit plate, the torq are arranged in the top of limit plate, the screw rod be located at the lower section of limit plate and with sliding block phase
Connection.
It is square aperture in the middle part of the traction framework in one preferred embodiment of the utility model.
In one preferred embodiment of the utility model, the bending of drag hook plate end, which is provided with, to be extended in square aperture
Bent plate, the bent plate bottom interval is provided with several hook items.
In one preferred embodiment of the utility model, the torq, screw rod and limit plate are integrated.
In one preferred embodiment of the utility model, the torq is sphere.
In one preferred embodiment of the utility model, the sliding slot is inverted T-slot.
In one preferred embodiment of the utility model, through-hole corresponding with screw rod is arranged at intervals on the drag hook plate.
The beneficial effects of the utility model are: the minimally invasive pull device in a kind of joint that the utility model is pointed out, utilizes sliding block
Movement in sliding slot, the lateral adjustments for carrying out drag hook plate are adjusted axially using the cooperation of screw rod and corresponding through-hole, greatly
The flexibility retracted to wound is improved greatly, is adapted to the scrambling of joint wound, is promoted the convenience of operation.
Detailed description of the invention
It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
