[0018] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] like Figure 1 , 2 As shown in Figure 5, an automatic sampling device for changing multiple sampling rods includes a housing 1 with an opening for the sampling rods 15 to enter and exit. A rotatable turntable 3 is located inside the housing 1, and its rotation is controlled by a turntable 3 rotation drive device connected to a main controller 2. Specifically, a gear ring 4 is provided along the outer edge of the turntable 3. Since a control device for opening or closing the opening needs to be installed inside the housing 1, the space at that location may be occupied. Therefore, in this technology, the gear ring 4 is preferably located at the end of the turntable 3, ensuring sufficient space for the turntable 3 rotation drive device. The turntable 3 rotation drive device includes a turntable drive motor 5 connected to the main controller 2. The output end of the turntable drive motor 5 has a drive gear 6 that meshes with the gear ring 4. The turntable drive motor 5 is fixed inside the housing 1, thereby stably outputting rotational power and ensuring the rotation control accuracy of the turntable 3.

[0020] Since the turntable 3 needs to rotate within the housing 1, and the gear ring 4 is located at the end of the turntable 3, a support structure cannot be provided at the end of the turntable 3. This technology provides a support shaft 7 inside the housing 1, inserted into the axis of one end of the turntable 3. The support shaft 7 is inserted from the end of the turntable 3 where the gear ring 4 is located. The other end of the turntable 3 is provided with a positioning support frame 8 fitted onto the outside of the turntable 3, and the positioning support frame 8 is fixed inside the housing 1. The front end of the turntable 3 is provided with a locking structure for locking the positioning support frame 8, preventing the positioning support frame 8 from moving axially along the turntable 3. Preferably, this technology provides an annular step at the front end of the turntable 3, so that the positioning support frame 8 is locked within the annular step, thereby restricting the axial freedom of the turntable 3, allowing the turntable 3 to only rotate within the housing 1.

[0021] The turntable 3 has several uniformly distributed cavities 9 parallel to the rotation axis of the turntable 3. The cavity 9 is an elongated cavity 9. Most of the structure of the sampling rod 15 is inserted into the cavity 9. The opening of the cavity 9 faces the opening of the shell.

[0022] like Figure 3As shown, the cavity 9 is equipped with a sampling feed device for controlling the movement of the sampling rod 15 along the cavity 9 and a sampling rotation device for controlling the rotation of the sampling rod 15. The sampling feed device includes a sampling feed motor 10, and the output end of the sampling feed motor 10 is provided with a sampling feed screw 11. The sampling feed screw 11 is provided with a sampling feed screw sleeve 12. The sampling feed screw sleeve 12 is a single-opening sampling feed screw sleeve 12. The inner hole of the sampling feed screw sleeve 12 is a threaded hole, and the threaded hole is threadedly matched with the feed screw. The outer end (non-opening side) of the sampling feed screw sleeve 12 is fixedly connected to the sampling rotation device. Both the sampling feed device and the sampling rotation device are connected to the main controller 2.

[0023] The sampling rotation device includes a sampling rotation motor 13. The output end of the sampling rotation motor 13 is provided with a sampling rod mounting body 14 for fixing the end of the sampling rod 15. The outer end of the sampling rod mounting body 14 is provided with a hole for the sampling rod 15 to be inserted. The sampling rod mounting body 14 and the sampling rod 15 are interference-fitted.

[0024] Since both the sampling feed device and the sampling rotation device need to rotate with the turntable 3, this technology adopts two methods. One method is that the turntable 3 rotates less than one revolution. For example, if the turntable 3 has four cavities 9, then the turntable 3 rotates only three-quarters of a revolution in each rotation cycle, and then returns to the origin and rotates three-quarters of a revolution in the opposite direction, repeating this process. This way, the wire will not be twisted. The other method is to set a conductive ring at the root of the turntable 3 to realize the rotation of the wire.

[0025] The turntable 3 is equipped with a rotation positioning device, which is connected to the main controller 2. The rotation positioning device controls the rotation drive of the turntable 3, ensuring that the opening of the cavity 9 aligns with the opening of the housing after each rotation of the turntable 3. The rotation positioning device includes a positioning contact 16 and a receiving contact 17. The positioning contact 16 is located on one side of the turntable 3 and corresponds one-to-one with the cavity 9. The receiving contact is fixed inside the housing 1. When the positioning contact 16 rotates with the turntable 3, it will touch the receiving contact. The receiving contact 17 is connected to the main controller 2.

[0026] For sampling sites that require an opening, such as gynecological vaginal sampling, this technology provides an expander at the opening of the housing 1. The expander includes an expander fixing part 18 that is fixedly connected to the housing 1 and an expander rotating part that is rotatably connected to the housing 1. The housing 1 is provided with an expander control device that controls the rotation of the expander rotating part, and the expander control device is connected to the main controller 2.

[0027] The expander rotating part has an expansion nozzle 19 and a rotation control body 20 on both sides of the rotation center. The expansion nozzle 19 is located outside the housing 1 and matches the expander fixing part 18. The rotation control body 20 is located inside the housing 1. The expander control device pushes the rotation control body 20 to rotate the expander rotating part. The rotation control body 20 is equipped with a spring that exerts a counter-force against the expander control device. The expander control device includes an expander opening motor 21. The output end of the expander opening motor 21 is equipped with an expander opening screw 22. The expansion opening screw 22 rotates and drives the expander opening screw sleeve 23 to feed, thereby pushing the rotation control body 20 to move towards the housing opening, so that the expander rotating part opens the housing opening due to rotation. When the expander opening motor 21 rotates in the opposite direction, the expander opening screw 22 drives the expander opening screw sleeve 23 to move in the opposite direction. The rotation control body 20 moves in the opposite direction due to the spring force, and the expander rotating part rotates in the opposite direction, thereby closing the housing opening.

[0028] To clearly visualize the sampling location, this technology incorporates a camera 24 positioned inside the housing 1, facing the housing opening, to capture video images of the sampling rod 15 in the feeding direction, thereby achieving precise positioning for deep sampling. Specifically, as... Figure 4 As shown, the support shaft 7 passes through the turntable 3. The support shaft 7 is a hollow tubular structure. A camera device 24 is provided at the shaft hole on the support shaft 7 facing the opening of the housing. A camera feed device is provided inside the support shaft 7 to control the movement of the camera device 24 along the inner hole of the support shaft 7. Specifically, the camera feed device includes a camera feed motor 28 disposed inside the support shaft 7. The output end of the camera feed motor 28 is provided with a camera feed screw 29 and a camera feed screw sleeve 30. The camera feed screw sleeve 30 is fitted onto the camera feed screw 29, and the outer end of the camera feed screw sleeve 30 is fixedly connected to the camera device 24.

[0029] A camera swing device is provided between the camera device 24 and the camera feed device. The camera swing device includes a swing motor 25, and an eccentric shaft 26 is provided at the output end of the swing motor 25. The camera device 24 is provided with a strip cavity 27 for the eccentric shaft 26 to swing horizontally. When the vertical position of the camera device 24 needs to be adjusted, the swing motor 25 rotates, driving the eccentric shaft 26 to rotate. The eccentric shaft 26 moves horizontally within the strip cavity 27. Since the camera device 24 is set in a vertical strip cavity 27, the camera device 24 moves vertically within the vertical strip cavity 27, thereby realizing the vertical movement of the camera device 24.

[0030] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
