Detailed Description
The utility model will be described in detail by way of example with reference to the accompanying drawings, which form a part hereof, and in which it is to be understood that the described embodiments are by way of illustration only, and not by way of limitation.
As shown in figure 1, a fracture resets interim fixer of steel sheet of being convenient for adjust, including an L type bottom plate 1 of invering, L type bottom plate 1's long limit top is provided with telescopic link 2, terminal fixed connection of telescopic link 2 is inboard at L type bottom plate 1's minor face, 2 outside covers of telescopic link are equipped with spring 3, the front end of telescopic link 2 and bottom plate 1 is provided with double-end movable claw 4 and single-end stationary dog 5 respectively, double-end movable claw 4 rotates with the front end of telescopic link 2 to be connected, the inboard of double-end movable claw 4 is provided with conical column 6.
In this embodiment, when the fracture reduction bone holder fixes two broken bones, the steel plate can be placed in the double-head movable claw 4 in advance, and the conical columns 6 on the inner side of the double-head movable claw 4 are respectively placed in the corresponding round holes on the steel plate, so that the steel plate is fixed. The spring 3 is tensioned, the single-head fixing claw 5 enters from one side of the fracture end, and the spring 3 resets to realize the fixation of the steel plate.
Spout 7 has all been seted up to the long limit both sides of bottom plate 1, be provided with on bottom plate 1 with spout 7 sliding connection's guide block 8, 8 fixed connection of guide block are at the front end of telescopic link 2, 3 one end fixed connection of spring are on guide block 8, and other end fixed connection is inboard at the minor face of bottom plate 1.
