The top of the rotating seat 4 is connected to the fixed seat 51, the connecting block 53 is embedded inside the fixed seat 51, the bottom of the connecting block 53 is connected to the positioning rod 52, the top of the connecting block 53 is connected to the control rod 55, and a fixing groove is opened on the surface of the mounting block 7, and the positioning rod 52 and the mounting block 7 are plug-in structures.

[0022] By adopting the above technical solution, after lifting the control rod 55 to insert the operating mechanism 6 into the rotating seat 4 through the mounting block 7, loosening the control rod 55 will allow the positioning rod 52 to engage with the positioning groove on the surface of the mounting block 7. The operating mechanism 6 and the mounting shell 8 are firmly connected and assembled, which can make the use of the device better.

[0023] Specifically, a spring 54 is sleeved on the surface of the control rod 55 inside the fixing seat 51 , and the side edge of the connecting block 53 is tightly fitted with the inner groove wall of the fixing seat 51 .

[0024] By adopting the above technical solution, the positioning rod 52 can be tightly plugged into the positioning groove on the surface of the mounting block 7 under the elastic force of the spring 54 on the connecting block 53, so that the connection between the operating mechanism 6 and the mounting shell 8 can be more firmly established.

[0025] When this embodiment is in use, lift the control rod 55 to insert the operating mechanism 6 into the rotating seat 4 through the mounting block 7, then release the control rod 55. Under the elastic force of the spring 54 on the connecting block 53, the positioning rod 52 can be tightly plugged into the positioning groove on the surface of the mounting block 7. The operating mechanism 6 and the mounting shell 8 are firmly connected and assembled to make the device more effective. The two cranks are rotated respectively to control the movement of the two vaginal dilator frames 1 to expand the vaginal opening, and then the operating mechanism 6 is rotated to drive the scraper ring 2 to rotate to scrape the wall. The airbag at the tail of the operating mechanism 6 can be pressed to clean out the foreign matter that has been cleaned. Example 2

[0026] The difference between this embodiment and embodiment 1 is that the control component 3 includes a positioning block 31, a screw 32 and a lifting plate 35, the screw 32 is embedded in the mounting shell 8, the positioning block 31 is sleeved on the surface of the screw 32 inside the mounting shell 8, and the side of the vaginal expansion frame 1 is connected to the lifting plate 35.

[0027] Specifically, a thread groove is provided inside the lifting plate 35 , and the thread directions of the surfaces at both ends of the screw rod 32 inside the mounting shell 8 are opposite.

[0028] By adopting the above technical solution, the rotating screw 32 can limit the rotation of the screw 32 under the action of the positioning block 31, and under the meshing connection between the screw 32 and the lifting plate 35, since the threads on the two end surfaces of the screw 32 are in opposite directions, the two lifting plates 35 can respectively drive the vaginal expansion frame 1 to move toward each other to expand the vaginal opening. The operation is simple and the device is more convenient to use.

[0029] Specifically, the side surface of the lifting plate 35 is connected to the limiting block 33 , and the side surface of the mounting shell 8 is provided with a limiting groove 34 .

[0030] By adopting the above technical solution, the limiting groove 34 limits the limiting block 33, so that the structural stability of the vaginal expansion frame 1 on one side of the lifting plate 35 is higher and the use effect is better.

[0031] When this embodiment is used, the rotating screw 32 can limit the rotation of the screw 32 under the action of the positioning block 31, and under the meshing connection between the screw 32 and the lifting plate 35, the limiting groove 34 limits the limiting block 33. Since the thread directions of the two end surfaces of the screw 32 are opposite, the two lifting plates 35 can respectively drive the vaginal expansion frame 1 to move toward each other to expand the vaginal opening. The operation is simple and the device is more convenient to use.

[0032] The structure and use principle of the vaginal dilator frame 1, scraper ring 2, rotating seat 4, operating mechanism 6, mounting block 7 and mounting shell 8 in the utility model have been disclosed in Chinese patent application No. 202210076516.9, which discloses a gynecological curettage device. Its working principle is to insert the operating mechanism 6 into the rotating seat 4 through the mounting block 7 and assemble it with the mounting shell 8, and rotate the two cranks respectively to control the movement of the two vaginal dilator frames 1 to expand the vaginal opening, and then rotate the operating mechanism 6 to drive the scraper ring 2 to rotate to scrape the wall, and press the airbag at the tail of the operating mechanism 6 to clean out the foreign matter that has been cleaned.

[0033] The working principle and use process of the utility model are as follows: when the utility model is used, after the control rod 55 is lifted to insert the operating mechanism 6 into the rotating seat 4 through the mounting block 7, the control rod 55 is loosened and the positioning rod 52 can be tightly plugged into the positioning groove on the surface of the mounting block 7 under the elastic force of the spring 54 on the connecting block 53. The operating mechanism 6 is firmly connected and assembled with the mounting shell 8, which can make the use effect of the gynecological and obstetrical curettage device better. The rotating screw rod 32 can limit the rotation of the screw rod 32 under the action of the positioning block 31, and under the meshing connection between the screw rod 32 and the lifting plate 35, the limiting groove 34 limits the limiting block 33. Because the thread directions of the surfaces at both ends of the screw rod 32 are opposite, the two lifting plates 35 can respectively drive the vaginal expansion frame 1 to move toward each other to expand the vaginal opening. The operation is simple and the device is more convenient to use. Then the operating mechanism 6 is rotated to drive the scraper ring 2 to rotate to scrape the wall, and the air bag at the tail of the operating mechanism 6 can be pressed to clean out the foreign matter that has been cleaned.
