The present invention removes；Reset operation should be carried out after removing：To above-mentioned opposite direction sliding rack 15, gear 2 is nibbled through rack 15
Close and rotate backward, screw rod 3 therewith rotate backward and screw-driven through screwed hole 4 and slided to the direction of gear 2, screw rod 3 with
Sliding block 6 separates, and under the elastic force effect of spring 7, sliding block 6 resets downwards ejection；Simultaneously as the elastic force effect of making leaf spring 14,
Push rod 12 rotates to the direction of screw rod 3 and through connecting rod 13 pulls the upward sliding of depression bar 10, and brake pad 11 separates with spheroid 9, compresses
Semi-ring 8 is active, and after rack 15 slides stopping, completing to reset operation, in order to reuse.
Clever structure of the present invention, it is simple to operate, under the be hinged synergy slided with sliding block of spheroid, compress semi-ring according to
The shape of patient's shin bone and produce rotation and offset and finally fitted with patient's shin bone, eliminate cushioning operation, simplify solid
Determine step；Meanwhile after completing to match with patient's shin bone, sliding block and compression semi-ring can be fixed on current state by sliding rack
It is set to turn into an entirety with fixed plate, to ensure that the elastic force of spring will not be acted on shin bone, and different parts after binding
Seizing force is transferred on shin bone through fixed plate is scattered, it is not necessary to worries that local pressure inequality causes junction to produce dislocation.
Compared to currently used fixing means, the present invention not only easily facilitates fixation, in general medical personnel
Operated, and will not increase unnecessary wound to patient after fixing, need not also carried out drilling operation to shin bone, alleviate trouble
