Do further explain below in conjunction with the accompanying drawing specific embodiments of the invention.
Fig. 1 is the sheath body 33 of single hole sheath of the present invention and the structural representation of sheath pin 32;
Fig. 2 is sheath medicated cap 31 and the structural representation of sheath body 33 of the single hole sheath of Fig. 1;
Fig. 3 is the structural representation of sheath pin 32 of the single hole sheath of Fig. 1;
Fig. 4 is the structural representation of sheath medicated cap 31 of the single hole sheath of Fig. 1.
The specific embodiment
Be provided with sheath pin 32 in the cylindrical shell cavity 16, sheath pin 32 comprises screw rod 3, and the upper end of screw rod 3 is fixed with seal washer 2, and the upper fixed of seal washer 2 has sealing ring 1, and the upper surface of sealing ring 1 is fixed with sheath pin cap 13; The lower end of screw rod 3 is fixed with conical spiral head 4; The internal diameter of the diameter of spiral head 4 and cylindrical shell 6 is identical, and (perhaps the diameter of spiral head 4 is littler than the internal diameter of cylindrical shell 6; Difference between the internal diameter of the diameter of spiral head 4 and cylindrical shell 6 is in 1mm), spiral head 4 is provided with screw thread.
This single hole sheath that has the sheath pin when unused state, with lock tube 5 and cylindrical shell 6 through being threaded screw rod 3 independent placements.
During the actual use of this single hole sheath, divide following steps;
