End.
It is both provided with screening glass on the inside of the left collet and right collet, left collet is fixed with screening glass with right collet
Connection.
Four finger sleeve rings are provided on the outside of the left clamp arm, four finger sleeve rings are strip ring structure, the side of four finger sleeve rings
With the structure that links into an integrated entity on the outside of left clamp arm, thumb lantern ring is provided on the outside of right clamp arm, thumb lantern ring is circular ring structure, thumb
Link into an integrated entity structure on the outside of the side of finger sleeve ring and right clamp arm.
The mandril is round bar with pull rod, and the diameter of pull rod is less than the diameter of mandril.
It is provided with internal thread on the inside of the position-limiting tube, is provided on the outside of pull rod and the matched external screw thread of position-limiting tube
Structure.
The limit base is vertically set on the side of pull rod, and limit base is corresponding with right clamp arm, is set on the inside of limit base
It is equipped with and the matched internal thread structure of caging bolt.
The fixed block include with the matched round slide of pull rod, what the both sides of the round slide were structure as a whole
Rectangular plate body.
Technical scheme of the present invention has following good effect：The left collet of the present invention and the opening angle of right collet and clamping
Angle can limit, and be conveniently operated and can cause to damage to avoid the head to fetus；Screening glass with head be isolated further protect
Baby head is protected, thumb lantern ring has further facilitated medical staff with four finger sleeve rings and operated with.
