Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to the attached drawings, the special gynecological medicine applicator comprises a main cylinder body 1, a piston assembly and an expansion assembly; a medicine outlet hole 101 is formed at the left end of the main cylinder body 1; the piston assembly comprises a piston plate 2 and a piston rod 201, the piston plate 2 is connected in the main cylinder body 1 in a sliding mode, and the inner end of the piston rod 201 is connected with the piston plate 2; the expansion assemblies are arranged in two groups, symmetrically arranged on the outer side of the main cylinder body 1, and each group comprises a stay bar, 4 and an expansion plate 6; the outer wall of the main cylinder body 1 is sleeved with a lantern ring 3 in a sliding way; the right end of the stay bar 4 is connected with the lantern ring 3 through a torsion spring, and the left end is connected with the inner side of the expansion plate 6; a plurality of grooves 7 are further formed in the outer wall of the main cylinder body 1 in the axial direction, and clamping blocks 9 are connected to the grooves 7 through springs 8.

Wherein, the outer end of the piston rod 201 is provided with an end plate 202 for easy push and pull.

Wherein, the left end of the main cylinder body 1 is processed with a hemispherical surface, and the piston plate 2 is correspondingly provided with a hemispherical convex block 10, which is convenient for discharging the liquid medicine.

Wherein, the fixture block 9 cross-section is right triangle, and the right-angle side on one side connects spring 8, and the hypotenuse is towards the right side, and when lantern ring 3 moved to the left like this, fixture block 9 received the effort and retracted earlier in recess 7, later popped out again and stops that lantern ring 3 slided to the right.

Wherein, four grooves 7 are uniformly arranged, and the interval is larger than the thickness of the lantern ring 3.

Wherein the torsion spring 5 makes the stay 4 have a tendency to rotate away from the main cylinder 1.
