Specific embodiment
The following detailed description of preferred embodiments of the present invention.
Embodiment 1: being the structural schematic diagram of the utility model embodiment 1 referring to Fig.1, including crossbeam 1, on the crossbeam 1
Equipped with fixed mechanism and pressing mechanism, the fixed mechanism is used to device described in the utility model being fixed on bone either
The two sides of internal fixation steel plate, the fixed mechanism include connecting rod 4 and fixed jaw 8, and one end of the connecting rod 4 is fixed at
The both ends of crossbeam 1 simultaneously constitute an inverse u shape bracket with crossbeam 1, and the other end is equipped with 2 " L " type fixed jaws 8, the fixed jaw 8
One end and connecting rod 4 between carried out hingedly by articulation piece 9, the other end is free end, and the free end is scarce equipped with " V " type
Mouthful, 2 fixed jaws 8 are that arranged symmetrically and fixed jaw 8 can be under the action of articulation piece 9 around the same hinge joint
