Specific embodiment
According to Fig. 1 to Fig. 4:
A kind of vertical fracture resetting tongs of metacarpophalangeal, including ontology 1, including being located at the clamping part 11 of 1 front end of ontology and being located at this
The grip part 12 of 1 rear end of body, the front end of the clamping part 11 are provided with cavity one, and inside of the cavity one relative to clamping part 11
Face is provided with opening；Fixed tip 2 is located in the cavity one, and the fixed tip 2 is flexible relative to cavity one, for into
One step fixes fracture；Telescoping mechanism 3, the ontology 1 are provided with cavity two, the telescopic machine relative to the telescoping mechanism 3
Structure 3 is located in cavity two, including interlock plate 32, and on the grip part 12 of the ontology 1, front end is provided with engaging lug 2 321,
Rear end is provided with fixing groove 322；Connector 31 is located in the cavity two, and one end connects the fixed tip 2, and the other end connects
The engaging lug 2 321 of the interlock plate 32 is connect, it is flexible to interlock fixed tip 3 for interlock plate 32；Fixed column 33 is located at described
On the grip part 12 of body 1, and it is located at the lower section of the interlock plate 32；For the cooperation of fixing groove 322 with interlock plate 32, connection is fixed
Position.
