The one side that described needle splint is relative with the bar cramp plate is respectively equipped with radial plane teeth.
Described pin clip slot is surrounded by right angle face on the pin holder and the little cambered surface on the needle splint; Described bar cramp groove is surrounded by big cambered surface on the bar cramp seat and the middle cambered surface on the bar cramp plate.
The outer end of described pin holder is provided with spherical groove, is provided with spherical washer in the spherical groove.
The outer end of described bar cramp seat is provided with cannelure, and stopping screw is located in the cannelure.
The little cambered surface of described needle splint and the middle cambered surface of bar cramp plate are provided with many fins.
Described fin is four.
Described pin clip slot can be transformed into the bar cramp groove, and the right angle face on this hour hands holder just is transformed into big cambered surface, and the little cambered surface on the needle splint just is transformed into middle cambered surface.
Good effect of the present utility model is as follows: owing to be provided with pre-lock spring, so pin clip slot and bar cramp groove have retractility, be convenient to very much clamp or take out draw point and connecting rod; Because the little cambered surface of needle splint and the middle cambered surface of bar cramp plate are provided with many fins, so guarantee that draw point and connecting rod are non-slip; Because the needle splint one side relative with the bar cramp plate is respectively equipped with radial plane teeth, relatively rotates so can prevent needle splint and bar cramp plate; By tightening stopping screw, can hold draw point and connecting rod tighter; This utility model is easy to use, and firm position can be realized three-dimensional clamping, is the vitals of bone external fixer.This utility model comprises two kinds of embodiment, and first kind of embodiment is pin-bar fixation clamp, and second kind of embodiment is bar-bar fixation clamp, and two kinds of embodiment can use
