In addition, the terms "first", "second" and the like are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0042] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms "set", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0043] In the prior art, the trainer is generally sold in a complete set, each set having a plurality of trainers of different sizes, and each trainer has a fixed size. Because there are a plurality of trainers in each set, there is a problem of high manufacturing cost; and because a plurality of trainers are packaged and transported at the same time, there is a problem of high transportation cost; and because only one or a few sizes of trainers are used at a time of use, there is a problem of waste of use. When using the trainer, the trainer of the appropriate size can be inserted into the corresponding position of the human body, and the human body is clamped to train the muscles of the part; for example, the sphincter muscle can be trained.

[0044] Therefore, the trainer comprises an expansion member 100, an elastic member 300 and an adjusting assembly 200; the expansion member 100 comprises a first branch 110 and a second branch 120, the first branch 110 and the second branch 120 are arranged at an angle; the elastic member 300 is connected with the first branch 110 and the second branch 120 respectively, for moving the ends of the first branch 110 and the second branch 120 away from each other; the adjusting assembly 200 is connected with the first branch 110 and the second branch 120 respectively, for adjusting and locking the distance between the ends of the first branch 110 and the second branch 120.

[0045] Specifically, the first branch 110 and the second branch 120 are arranged at a distance from each other, and the distance can be adjusted and locked by the adjusting assembly 200, so that the overall size of the expansion member 100 is adjusted to a suitable size; wherein the locking means fixing the distance at a certain value. Further, the first branch 110 and the second branch 120 of the expansion member 100 are made of flexible material, and the first branch 110 and the second branch 120 are integrally formed; the outer surface of the expansion member 100 is used to contact the skin of the human body; in the embodiment, the material of the expansion member 100 is silica gel; of course, the expansion member 100 made of other flexible materials should also be within the protection scope of the embodiment.

[0046] The expansion member 100 includes the first branch 110 and the second branch 120 arranged at an angle, forming the basic shape of the training device; the adjusting assembly 200 can adjust the distance between the ends of the first branch 110 and the second branch 120, so as to adjust the overall size of the training device; the adjusting assembly 200 can lock the distance between the ends of the first branch 110 and the second branch 120, so that after the overall size of the training device is adjusted to be appropriate, the training device can be locked for normal use; the elastic member 300 is connected with the first branch 110 and the second branch 120 respectively, has elasticity, and when the adjusting assembly 200 applies force to the first branch 110 or the second branch 120 to reduce the distance between the ends of the first branch 110 and the second branch 120, the elastic member 300 is compressed and has elastic force; when the adjusting assembly 200 cancels the force applied to the first branch 110 or the second branch 120, the elastic member 300 drives the ends of the first branch 110 and the second branch 120 to be away from each other and reset; and the elastic member 300 can also play an expansion role in use.

[0047] The first branch 110 and the second branch 120 of the expansion member 100 form the basic shape of the training device, so that the training device has normal expansion performance; the adjusting assembly 200 can adjust and lock the distance between the ends of the first branch 110 and the second branch 120, so as to change the overall size of the training device. The training device can adjust the distance between the ends of the first branch 110 and the second branch 120 to the required distance as needed and be locked, and does not need to be sold in a complete set, so that a single training device can be used universally, the manufacturing cost and the transportation cost are reduced, the problem of waste in use is avoided, and the use convenience and the storage convenience are improved.

[0048] In the optional scheme of the embodiment of the utility model, the first end of the first branch 110 and the first end of the second branch 120 are connected at an angle.

[0049] Specifically, the first branch 110 and the second branch 120 are connected to form the expansion member 100 in a V shape.

[0050] The first end of the first branch 110 and the first end of the second branch 120 are connected, so that the expansion member 100 is an integral whole, facilitating production and processing, and preventing the first end of the first branch 110 and the first end of the second branch 120 from being misaligned and injuring the user during use.

[0051] In an optional solution of the embodiment of the utility model, the elastic member 300 comprises a first elastic part 310 and a second elastic part 320; the first elastic part 310 and the second elastic part 320 are connected at an angle, and the first elastic part 310 is connected with the first branch 110, and the second elastic part 320 is connected with the second branch 120. Of course, the elastic member 300 is linear, and the solution that the two ends are connected with the end of the first branch 110 and the end of the second branch 120 respectively should also be within the protection scope of the embodiment of the utility model.

[0052] Specifically, the first elastic part 310 and the second elastic part 320 are integrally formed, for example, the elastic member 300 with the first elastic part 310 and the second elastic part 320 is formed by bending an elastic sheet.

[0053] The first elastic part 310 is connected with the first branch 110, and the second elastic part 320 is connected with the second branch 120, so that when the first branch 110 or the second branch 120 is squeezed, the elastic member 300 will be elastically deformed, so that when the squeezing is cancelled, the first branch 110 and the second branch 120 can be reset. In addition, the first elastic part 310 is connected with the first branch 110, which also supports the first branch 110; similarly, the second elastic part 320 supports the second branch 120.

[0054] As an implementation manner, the elastic member 300 is embedded in the inside of the expansion member 100, and the first elastic part 310 extends into the first branch 110, and the second elastic part 320 extends into the second branch 120.

[0055] Specifically, in the embodiment, the elastic member 300 is a metal elastic sheet, and the metal elastic sheet is bent as a whole to be V-shaped, forming the first elastic part 310 and the second elastic part 320 connected at an angle; see Figure 1 , Figure 1The middle metal spring is indicated by a dashed line; the whole metal spring is embedded in the expansion member 100, the tip is located at the connection of the first branch 110 and the second branch 120, and the two ends extend into the first branch 110 and the second branch 120, respectively. The metal spring is made of a memory alloy. The metal spring has elasticity, and the two ends of the metal spring are away from each other to separate the ends of the first branch 110 and the second branch 120 and form a spacing; and the metal spring has strength and can be used to support the first branch 110 and the second branch 120. Of course, the elastic member 300 is provided as an elastic metal wire or other structure with elasticity, which should also be within the protection scope of the embodiments of the utility model. Further, referring to Figure 1 and Figure 2 The inner wall of the metal spring is provided with a reinforcing protrusion 350, which extends along the length direction of the metal spring and is located in the middle of the metal spring.

[0056] The elastic member 300 elastically deforms following the change of the spacing between the first branch 110 and the second branch 120, realizes the reset when the force of the adjusting assembly 200 on the first branch 110 and the second branch 120 is cancelled, and plays an expansion role in use. In addition, because the elastic member 300 is embedded in the inside of the expansion member 100, the expansion member 100 can protect the elastic member 300 and avoid the problem of falling off of the elastic member 300.

[0057] As another embodiment, the first elastic part 310 is connected with the surface opposite to the first branch 110 and the second branch 120, and the second elastic part 320 is connected with the surface opposite to the second branch 120 and the first branch 110.

[0058] In the optional scheme of the embodiments of the utility model, the end of the first elastic part 310 away from the second elastic part 320 extends in the direction away from the second branch 120 to form a first extension 330, and the end of the second elastic part 320 away from the first elastic part 310 extends in the direction away from the first branch 110 to form a second extension 340.

The first limiting part 111 and the second limiting part 121 facilitate the user to hold the training device, and play a limiting role when in use. Further, the first limiting part 111, the first branch 110, the second branch 120 and the second limiting part 121 are integrally formed, which facilitates manufacturing and strengthens the connection strength between adjacent two components.

[0060] The first extending part 330 and the second extending part 340 extend into the first limiting part 111 and the second limiting part 121 respectively, which strengthens the strength of the first limiting part 111 and the second limiting part 121, and realizes the deformation of the driving elastic piece 300 by extruding the first limiting part 111 and the second limiting part 121, so as to adjust the distance between the end of the first branch 110 and the end of the second branch 120. The elastic piece 300 makes the end of the first branch 110 and the end of the second branch 120 have a mutual moving away trend, so that the first branch 110 and the second branch 120 have an expansion function, and the elastic piece 300 can restore the original shape to reset the driving expansion piece 100 when the external force is removed.

[0061] In the optional scheme of the utility model embodiment, the bottom of the connection part of the first branch 110 and the second branch 120 has a thickening part 130, and the first branch 110, the second branch 120 and the thickening part 130 are integrally formed.

[0062] Specifically, the cross-sectional area of the thickening part 130 gradually increases from bottom to top in the direction shown in the figure, and is transitionally connected with the first branch 110 and the second branch 120. Figure 1 The thickening part 130 is made of the same material as the first branch 110. The first branch 110, the second branch 120 and the thickening part 130 can be integrally formed by injection molding process; for example, when injection molding is used, two molds are designed, and the metal spring piece is fixed in the appropriate position of the mold by using a small amount of silica gel, and then the mold is closed and injection molded.

[0063] The thickening part 130 is located at the bottom of the expansion piece 100, which increases the thickness of the bottom of the expansion piece 100, enhances the expansion force of the expansion piece 100, and ensures the expansion of the shape.

[0064] In the optional scheme of the embodiment of the utility model, the side wall of the thickening part 130 is provided with a groove, the groove is used for placing objects such as medicines, and the training device can push the objects such as medicines into the human body. When using, the medicine can be clamped into the groove, or the medicine is dissolved on the surface with water and then stuck in the groove, and then the training device is pushed into the user's body, and after a certain time, it can be taken out.

When using, the plug can be removed first, the liquid is injected into the channel, and then the plug is plugged into the channel; the training device is pushed into the user's body.

[0066] In the optional scheme of the embodiment of the utility model, the adjusting assembly 200 comprises a first adjusting piece arranged on the first branch 110 and a second adjusting piece arranged on the second branch 120; the first adjusting piece and the second adjusting piece are adjustably connected.

[0067] The first adjusting piece and the second adjusting piece are adjustably connected, so that the adjusting assembly 200 can adjust the distance between the end of the first branch 110 and the end of the second branch 120.

[0068] In the optional scheme of the embodiment of the utility model, the first adjusting piece is arranged as an adjusting strip 210, the adjusting strip 210 is connected to the end of the first branch 110, and the adjusting strip 210 is adjustably connected with the second adjusting piece.

[0069] Specifically, the adjusting strip 210 is rectangular, and one end is connected at an angle with the end of the first branch 110, and the end face of the other end is arc-shaped. The end of the adjusting strip 210 is arc-shaped, which avoids hurting the user and facilitates cooperation with the second adjusting piece. Preferably, the adjusting strip 210 is integrally formed with the first branch 110.

[0070] The different positions of the adjusting strip 210 are connected with the second adjusting piece, so as to adjust the distance between the end of the first branch 110 and the end of the second branch 120, and the adjustable range is increased.

[0071] In the optional scheme of the embodiment of the utility model, the adjusting strip 210 is provided with a plurality of first adjusting structures arranged at intervals along the length direction of the adjusting strip 210, the second adjusting piece is arranged as a second adjusting structure matched with the first adjusting structure, and the second adjusting structure is selectively detachably connected with the first adjusting structure.

[0072] Specifically, the second adjusting structure is clamped with the first adjusting structure. Further, each first adjusting structure or the vicinity of the first adjusting structure is provided with an identification element, which is used to identify the overall size of the trainer when the first adjusting structure is clamped with the second adjusting structure; the identification element can be provided as a scale.

[0073] The plurality of first adjusting structures are arranged at intervals along the length direction of the adjusting strip 210, so that different positions of the adjusting strip 210 can be connected with the second adjusting structure, facilitating operation.

[0074] As the first embodiment, refer to Figures 1 to 3 , the first adjusting structure is provided as an adjusting protrusion 230, and the second adjusting structure is provided as an adjusting hole 220.

[0075] By clamping the adjusting hole 220 with different adjusting protrusions 230, the spacing between the end of the first branch 110 and the end of the second branch 120 is adjusted and locked, and the overall size of the expansion piece 100 is adjusted and locked. Moreover, the clamping mode of the adjusting protrusion 230 with the adjusting hole 220 is simple in structure and easy to operate.

[0076] Further, the adjusting protrusion 230 has an inclined surface.

[0077] Specifically, the cross section of the adjusting protrusion 230 is a right triangle, in which the surface away from the adjusting strip 210 is the inclined surface, the surface adhering to the adjusting strip 210 is the first surface, and the surface perpendicular to the adjusting strip 210 is the second surface; when adjusting the size of the expansion piece 100, the adjusting strip 210 is pulled after being inserted into the adjusting hole 220, and the inclined surface of the adjusting block helps the adjusting block to pass through the first adjusting hole 220; when the pulling of the adjusting strip 210 is stopped, the second surface of the adjusting protrusion 230 corresponding to the position of the adjusting hole 220 abuts against the inner wall of the second branch 120, so as to lock the adjusting strip 210.

[0078] The inclined surface of the adjusting protrusion 230 helps the adjusting block to pass through the adjusting hole 220, and the second surface of the adjusting protrusion 230 realizes the locking of the adjusting strip 210.

[0079] As the second embodiment, refer to Figure 4 and Figure 5 On the basis of the above-mentioned first embodiment, the adjusting protrusion 230 is provided with two groups, and the two groups of adjusting protrusions 230 are respectively located on the left and right sides of the adjusting strip 210.

The two groups of adjusting protrusions 230 are respectively located on the left and right sides of the adjusting strip 210.

[0081] The plurality of adjusting protrusions 230 in the two groups are arranged one by one to enhance the locking strength; or, the plurality of adjusting protrusions 230 in the two groups are arranged staggeredly; for example, the adjusting protrusion 230 on the left side of the adjusting strip 210 is opposite to the gap between the two adjacent adjusting protrusions 230 on the right side of the adjusting strip 210, so that the size range of the expandable member 100 can be adjusted.
