The lower section of expander shell body is internally provided with expander adjusting bolt, the surface of the right extension head close to left side handle
Right extension head protrusion is provided with, and one end of right extension head is provided with dextral handle, the surface of the dextral handle is set
There is a nut angular adjustment bar, and dextral handle is internally provided with nut, the both sides of the nut are both provided with nut shaft, institute
State the prolate-headed surface in left side and be provided with left side extension head protrusion.
Preferably, the expander shell body is rotatablely connected with right extension head by opening shaft.
Preferably, the nut is rotatablely connected with dextral handle by nut shaft.
Preferably, the dextral handle is fixedly connected with left side handle by expander adjusting bolt.
Preferably, the left side extension head protrusion is evenly distributed on the prolate-headed surface in left side.
The beneficial effect that the utility model is reached is：The utility model scientific structure design is reasonable, simple to operate,
It is sturdy and durable, rubber projections are devised on the outside of expander, prevent medical staff in expansion process, expander is slided from introitus
Go out, increase frictional force；And be designed as rotatably in the bolt of expander handle inner, convenient be used in is expanded using bolt control
When opening up device openings of sizes, bolt is not in rotate dead angle so that opening further increases.
