One servo motor is equipped with an internal gear on the motor shaft of first servo motor, one is slidably fitted on the inside of internal gear
Second sliding block, is equipped with second servo motor on the second sliding block, and the motor shaft of the second servo motor is equipped with outside one
Gear, the external gear are engaged with internal gear, and a third servo motor, third servo motor are equipped on the second sliding block
Motor shaft on an articulated slab is installed, symmetrically hingedly there are two semicircle claws for installation on the top of articulated slab, in articulated slab
Outside is symmetrically installed there are two the 5th electric cylinders, and the piston rod upper end of the 5th electric cylinders and semicircle claw outside hingedly, pass through the 5th
Electric cylinders control the opening and closing of semicircle claw.
The invention has the advantages that:
1. the present invention facilitates patient to fix at the both ends of fractured leg respectively by two transportable fixed cells of setting.
2. constituting the parallel institution of a comprehensive swing by setting the second electric cylinders, third electric cylinders, the 4th electric cylinders, lead to
Crossing the movement in internal gear of the second sliding block may be implemented semicircle claw around the axial torsion of leg, and the both ends of fractured leg can be made to dock
It is more accurate.

Embodiment
As shown in Figure 1 and Figure 2, equipment, including 1, two fixed cell of guide rail, feature is auxiliarily fixed in a kind of Medical bone
Be: the fixed cell includes the first sliding block 2, electric cylinders fixing seat 3, the first electric cylinders 4, hinged-support 5, the 6, second electricity of lower disc
It is cylinder 7, third electric cylinders 8, the 4th electric cylinders 9, upper disk 10, first servo motor 11, the second sliding block 12, the second servo motor 13, outer
Gear 14, third servo motor 15, articulated slab 16, the 5th electric cylinders 17, semicircle claw 18, internal gear 19, sliding slot 20, two fixations
Unit is mounted on guide rail 1, and the electric cylinders fixing seat 3 is fixed on 1 end of guide rail, and the first sliding block 2 is slidably mounted on guide rail 1
On, the first sliding block 2 is driven by the first electric cylinders 4, and 4 one end of the first electric cylinders is fixed in electric cylinders fixing seat 3, and the other end is fixed on first
On sliding block 2, the lower disc 6 is fixed on 2 top of the first sliding block, is fixedly installed with one in 6 upper center position of lower disc
