[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] Example 1;

[0027] Please see Figures 1 to 4 To facilitate the positioning of slider 6, this utility model provides a technical solution: a puncture positioning device, which is mainly used in the scenario of positioning puncture needles. It includes a placement plate 1 and a positioning barrel 2. A limiting post 14 for fixing is inserted into the lower end of the placement plate 1. The limiting post 14 passes through one side of the placement plate 1 and is threaded to the inner wall of slider 6. A baffle 15 is bolted to the side of the placement plate 1. A fixing post 16 is inserted into the side of the baffle 15. A telescopic rod 3 for adjustment is threaded to the lower end of the placement plate 1. With the setting of the limiting post 14, slider 6 is limited, ensuring that slider 6 can be more conveniently limited after sliding to a suitable position in the slide groove 5, avoiding slider 6 from leaving the slide groove 5 or excessive displacement. With the setting of the baffle 15, one side of the slide groove 5 can be limited, preventing slider 6 from leaving the slide groove 5 during movement. With the setting of the fixing post 16, the baffle 15 can be further fixed, enhancing the connection strength of the baffle 15 on the placement plate 1.

[0028] Example 2;

[0029] Please see Figures 1 to 4To facilitate the fixing of the telescopic rod 3, a support rod 4 for limiting is sleeved on the outer surface of the telescopic rod 3. A threaded post 7 for fixing is inserted into the side of the support rod 4. The threaded post 7 passes through one side of the support rod 4 and is threaded to the inner wall of the telescopic rod 3. A fastening shell 12 for fixing is threaded to one end of the support rod 4. A positioning pin 13 for fixing is inserted into the lower end of the fastening shell 12. With the help of the threaded post 7, after the staff has adjusted the support rod 4, it can fasten the connection between the support rod 4 and the telescopic rod 3, preventing them from loosening or separating due to external forces during use, ensuring the stability of the height adjustment structure, and thus ensuring the reliability of the entire puncture positioning device during use. With the help of the fastening shell 12 and the positioning pin 13, it is easy for the staff to fix the device in a suitable position.

[0030] Example 3;

[0031] Please see Figures 1 to 4 The upper end of the placement plate 1 is provided with a positioning groove 5. The inner wall of the groove 5 is fitted with a positioning slider 6. One end of the slider 6 is fixedly connected to a limiting connecting plate 8. The outer surface of the connecting plate 8 is fitted with a positioning rotating plate 9. The upper end of the rotating plate 9 is inserted with a connecting shaft 10. The rotating shaft 10 passes through one side of the rotating plate 9 and is threaded to the inner wall of the connecting plate 8. The inner wall of the rotating plate 9 is fitted with the outer surface of the positioning barrel 2. One end of the rotating shaft 10 is threaded with a fastening nut 11. The outer surface of the nut 11 is provided with friction texture for anti-slip.

[0032] The connecting plate 8, as the intermediate component connecting the slider 6 and the rotating plate 9, transmits the positional changes caused by the movement of the slider 6 within the groove 5 to the rotating plate 9. It also provides a stable connection base for the rotating plate 9, ensuring its smooth rotation around the rotating shaft 10 and enabling corresponding positioning angle adjustments. The upper end of the rotating plate 9 is connected to the connecting plate 8 via the rotating shaft 10, allowing it to rotate around the shaft. This rotation adjusts the angle of the positioning barrel 2, which is engaged with its inner wall, allowing for flexible adjustment of the positioning barrel 2's planar angle to meet different puncture angle requirements. After adjustment, the nut 11 facilitates the fixation of the rotating shaft 10. When screwed onto one end of the rotating shaft 10, the nut 11 provides better tightening, preventing loosening due to vibration or other factors during use. This ensures a stable connection between the rotating plate 9 and the connecting plate 8, maintains the accuracy of the rotating plate 9's rotation angle, and prevents the positioning angle of the positioning barrel 2 from changing arbitrarily.

[0033] In this invention, the working steps of the device are as follows:

[0034] First, the device is fixed in the desired position using the fastening housing 12. According to the required height, the telescopic rod 3 is pulled to the appropriate position so that the placement plate 1 reaches the appropriate height. The threaded column 7 is threaded through one side of the support rod 4 and connected to the inner wall of the telescopic rod 3, thus fastening the connection between the support rod 4 and the telescopic rod 3. The slider 6 is pushed to move in the groove 5 opened at the upper end of the placement plate 1. The position change of the slider 6 is transmitted to the rotating plate 9 through the connecting plate 8 fixedly connected to one end of it. At the same time, the rotating plate 9 is adjusted to rotate around the rotating shaft 10, thereby driving the positioning barrel 2, which is engaged with its inner wall, to rotate. This allows for flexible adjustment of the positioning barrel 2 in terms of plane angle to meet different puncture angle requirements.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
