[0041] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0042] Example 1:

[0043] like Figure 1-6 As shown, the utility model provides a mechanism for convenient replacement of the needle 61, the mechanism comprising: a column assembly 4, a flipping mechanism 5, a prefabricated needle 6 detachably arranged on the flipping mechanism 5 and a slide base 2; a mounting position is provided on the column assembly 4; one end of the flipping mechanism 5 is rotatably arranged with respect to the mounting position of the column assembly 4, so that the flipping mechanism 5 can flip at a preset angle relative to the mounting position; the prefabricated needle 6 is connected to the prefabricated liquid through an infusion pipe 54; a slide 3 is provided on the slide base 2, and the position of the slide 3 is opposite to the needle head 61 of the prefabricated needle 6; wherein, the prefabricated needle 6 is configured to flip synchronously with the flipping mechanism 5, and when flipping to the starting point, the needle head 61 of the prefabricated needle 6 is opposite to the slide 3, and when flipping to the end point, the prefabricated needle 6 is away from the slide 3.

[0044] Specifically, the present invention provides a mechanism for conveniently replacing a needle 61, aiming to improve the efficiency and safety of needle 61 replacement in a laboratory or medical setting. The mechanism consists of several key components: a column assembly 4, including a column 41, which serves as the foundation of the entire mechanism and is provided with a precise mounting position; a flip mechanism 5, one end of which is connected to the mounting position of the column assembly 4, allowing it to be flipped at a precisely controlled preset angle; and a prefabricated needle 6, which is connected to a prefabricated liquid via an infusion tube 54 to ensure the continuity of the liquid supply during the replacement process. Furthermore, the prefabricated needle 6 and the flip mechanism 5 are detachable for quick replacement, as well as a slide base 2, on which a precisely positioned slide 3 is provided to ensure that the needle 61 of the prefabricated needle 6 is aligned with the slide 3. The entire mechanism design allows the preformed needle 6 to rotate synchronously with the turning mechanism 5. When turning to the starting point, the needle tip 61 of the preformed needle 6 can be precisely aligned with the glass slide 3, facilitating experimental or therapeutic operations. When turning to the end point, the preformed needle 6 is away from the glass slide 3, ensuring operator safety and facilitating the replacement or maintenance of the needle tip 61. This design not only improves operational convenience but also significantly reduces the risk of cross-infection, making it a very practical innovation in the laboratory and medical fields.

[0045] Regarding the installation method of the preformed needle 6, this embodiment also proposes an implementation method in which the flip mechanism 5 also includes a connecting plate, one end of which is fixedly connected to the flip plate 51. The flip plate 51 is provided with a connecting hole, and the preformed needle 6 is detachably mounted in the connecting hole. Furthermore, the preformed needle 6 is mounted in the connecting hole via a joint 52. The outer wall of the joint 52 is provided with an external thread. The joint 52 is inserted into the connecting hole and is restrained by a nut 53. When the preformed needle 6 needs to be replaced, it is only necessary to apply force to unplug the old preformed needle 6 plugged into the joint 52.

[0046] The specific flipping of the flip mechanism 5 and the column assembly 4 comprises a flip plate 51, which is provided with a mounting hole for passing the infusion pipe 54 through the flip plate 51. A pair of holes for the rotating shaft 42 are also provided on a pair of opposing outer walls of the flip plate 51. The column mounting position is provided with a mounting slot, and a pair of rotating shafts 42 are formed on the opposing inner walls of the slot. The flip plate 51 is mounted in the mounting slot, and the pair of holes for the rotating shaft 42 of the flip plate 51 are rotatably connected by a pair of rotating shafts 42 on the corresponding sides. This allows the flip plate 51 to rotate relative to the rotating shaft 42 when it is pushed by an external force.

[0047] In order to enable the flip plate 51 to be automatically fixed in the initial position and the end position, this embodiment further proposes an implementation method, wherein the mechanism further includes: a first sub-connector 55, the first sub-connector 55 being located on a side of the connecting plate close to the column, the column being provided with a first female connector 44, the first female connector 44 being located in the direction when the flip plate 51 drives the mounting plate to move clockwise toward the column, and facing the displacement path of the first sub-connector 55; the mechanism further includes: a second sub-connector 56, the second sub-connector 56 being located on a side of the connecting plate away from the column; the column being provided with a second female connector 43, the second female connector 43 being located in the direction when the flip plate 51 drives the mounting plate to move counterclockwise toward the column, and facing the displacement path of the second sub-connector 56. In the first aspect, the first sub-connector 55, the second sub-connector 56, the first female connector 44, and the second female connector 43 are all magnetic components.

[0048] In the above embodiment, a mechanism for automatically securing the flip plate 51 is described in detail to ensure stability and accuracy in both its initial and final positions. The key components of this mechanism include two sub-connectors and two female connectors, which work together to automatically position and secure the flip plate 51. The first sub-connector 55 is mounted on the side of the connecting plate closest to the column, while the corresponding first female connector 44 on the column is located in the path of the flip plate 51 as it rotates clockwise toward the column, ensuring accurate alignment and magnetic securement. Similarly, the second sub-connector 56 is located on the side of the connecting plate away from the column, while the second female connector 43 on the column is located in the path of the flip plate 51 as it rotates counterclockwise toward the column, securing the other end. This design not only improves the accuracy of the flip plate 51's positioning but also, through the use of magnetic elements, simplifies the securing and release process, reduces mechanical wear, and extends the life of the mechanism. Furthermore, the magnetic connector configuration provides fast response and high reliability, making the entire mechanism smoother and safer during operation. Through this innovative connection method, the mechanism of this embodiment can be widely used in various application scenarios that require precise control of the position of the flip plate 51, such as automation equipment, precision instruments, etc., which significantly improves the convenience of operation and the stability of the equipment.
