In this embodiment, the discharge end 12 has a round bullet structure, so that the discharge end 12 has a streamline structure, and friction force when entering a human body is reduced. The discharge end 12 is of a petal configuration including a plurality of petals disposed adjacent one another. When the forming is finished, the petals are opened and are filled into the sanitary silver, after the forming is performed by heating, each petal part is gathered, and the adjacent petal parts are movably closed, so that the sanitary silver can be effectively prevented from being polluted before being used, and the sterility of the sanitary silver is improved.

The hand-held part 12 comprises an elastic component 14 arranged on the inner side of the hand-held part, the elastic component 14 forms a channel matched with the push rod 2, the elastic component 14 comprises a plurality of elastic pieces 16 arranged along the axial direction of the sleeve 1, and each elastic piece 16 is at least partially movably matched with the push rod 2. The elastic members 16 are provided in two or more, and are uniformly provided on the same circumferential surface. When push rod 2 gets into cavity 11 through the passageway, elastic component 14's setting can play axial support effect to push rod 2, makes push rod 2 steady, can not take place the circumference and rocks, and can prevent that the tampon from appearing the circumference and rocking when pushing in the body to avoid the silver body to push into the in-process and rock and arouse user's discomfort, improve the use experience.

In the present embodiment, as shown in fig. 4, the elastic member 16 is a spring plate 17. The elastic piece 17 comprises a fixed end 18 and a free end 19, and the elastic piece 17 is adjacently arranged along the inner side surface of the hand-held part 12. The free end 19 extends towards the tail of the sleeve 1, and the fixed end 19 is attached to the inner side surface of the holding part 12. As a preferred embodiment, the fixed ends 19 of all the spring plates 17 extend circumferentially and are connected to each other to form a ring structure, thereby improving the stability of the spring plates 17 and reducing the difficulty of the process.

The spring plate 17 is obliquely arranged relative to the central line gamma of the sleeve 1, and the free end 19 is gathered towards the central line gamma of the sleeve 1. That is, the channel is arranged in a variable diameter way, and the diameter of one end close to the cavity 11 is large, and the diameter of one end far away from the cavity 11 is small. As a preferred embodiment, the angle formed by the spring 17 and the central line of the sleeve 1 is 15-60 degrees. The push rod 1 can be of equal diameter, the diameter is gradually changed, the diameter of one end of the push rod 1 positioned in the sleeve 1 is large, the diameter of one end of the push rod 1 positioned outside the sleeve 1 is small, and the side surface of the push rod 2 is tightly adhered to the elastic sheet 17, so that certain friction force is generated in the pulling process of the push rod 2, a better positioning effect is achieved, a phenomenon that a user carelessly loosens hands in the using process is prevented, the push rod 2 axially slides is prevented, and the user can be prevented from causing uncomfortable feeling due to too large pushing force and pushing out a sanitary sliver in advance due to misoperation in the using process. For convenience of description, the push rod 2 in this embodiment adopts an equal diameter arrangement.

As a preferred embodiment, the elastic sheet 17 further includes a clasping structure 20 disposed at the free end 19, and the clasping structure 20 is movably abutted against the push rod 2. The clasping structure 20 may be any structure having a clasping effect, such as a claw head structure.

The other end of the push rod 2 is provided with a second horn-shaped structure 35, and the cross-sectional diameter of the second horn-shaped structure 35 is larger than that of the first horn-shaped structure 33 and larger than that of the channel formed by the ridge group 50. Thus, during assembly, the first horn 33 can pass through the hand-held portion 12, while the second horn 35 cannot pass through the hand-held portion 12, so as to achieve the connection of the push rod 2 with the sleeve 1 and the assembly effect at least partially in the sleeve 1.

In some embodiments, the hand-hold portion 12 includes an anti-slip layer 34 disposed on the surface, the anti-slip layer 34 is a silica gel convex structure or a silica gel coating surface with a hollow structure, and by disposing the anti-slip layer 34 made of silica gel, the roughness of the surface of the hand-hold portion 12 is improved, so as to prevent a user from slipping when using the hand-hold portion, and the hand-hold portion is not firmly held and falls, or the push rod 2 cannot be pushed due to slipping, so that the reliability of use is further improved. In some embodiments, the silicone convexity or hollows may be a flower-shaped or logo-shaped structure for improved aesthetics or logo.

The elastic sheet 17 in this embodiment is one of PE, PVC, PP, PET and silica gel, has a certain elasticity and toughness, and has better fracture and compression resistance capability, so as to prevent the elastic member from losing elasticity when not used for a long time, thereby ensuring long-term effective matching between the elastic member 14 and the push rod 2.
