Electric cylinders control semicircle claw opening and closing.
Beneficial effect of the present invention:
1. the present invention facilitates patient to fix at the two ends of fractured leg respectively by setting two transportable fixed cells.
2. by setting the second electric cylinders, the 3rd electric cylinders, the 4th electric cylinders, constituting the parallel institution of a comprehensive swing, lead to
Axial torsion of the semicircle claw around leg can be realized by crossing the movement in internal gear of the second sliding block, can dock the two ends of fractured leg
It is more accurate.

Embodiment
As shown in Figure 1 and Figure 2, a kind of Medical bone auxiliary fixing equipment, including guide rail 1, two fixed cells, it is characterised in that:
Described fixed cell include the first sliding block 2, electric cylinders fixed seat 3, the first electric cylinders 4, hinged-support 5, lower disc 6, the second electric cylinders 7,
3rd electric cylinders 8, the 4th electric cylinders 9, upper disk 10, the first servomotor 11, the second sliding block 12, the second servomotor 13, external gear
14th, the 3rd servomotor 15, articulated slab 16, the 5th electric cylinders 17, semicircle claw 18, internal gear 19, chute 20, two fixed cells
On guide rail 1, described electric cylinders fixed seat 3 is fixed on the end of guide rail 1, and the first sliding block 2 is slidably mounted on guide rail 1, the
