[0030] In order to save manpower and improve efficiency, as an embodiment of the utility model, as shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 The yarn nozzle structure of the utility model for the flat knitting machine includes a yarn nozzle body 1, a connecting shaft 2, a support frame 3 and a bolt 31, the connecting column 11 is installed on the outer wall of the upper end of the yarn nozzle body 1, the fitting column 13 is installed on one side of the outer wall of the upper end of the connecting column 11, the clamping groove 12 in circular array is formed on one side of the outer wall of the connecting column 11, the connecting shaft 2 is arranged on the upper end of the connecting column 11, the limiting ring 23 is welded on one side of the outer wall of the connecting shaft 2, the first spring 25 is arranged on the outer wall of the lower end of the limiting ring 23, the connecting cover 24 is arranged on the outer wall of the lower end of the first spring 25, the support frame 3 in circular array is welded on the lower end of the outer wall of the connecting shaft 2, and the bolt 31 is movably installed in the support frame 3.

[0031] In use, the design of the connecting column 11 and the fitting column 13 facilitates the precise docking of the yarn nozzle body 1 with the connecting shaft 2, and the circular array of the clamping grooves 12 provides a stable fixing point for the plug 31, ensuring the stability of the yarn nozzle body 1 after subsequent fixation. The first spring 25 maintains the use position of the connecting cover 24, so that the connecting cover 24 can limit the use position of the plug 31, keeping the plug 31 stable inside the clamping groove 12 and ensuring the stability of the connection of the connecting column 11 with the lower end of the connecting shaft 2. The yarn nozzle body 1 is provided with brushes on both sides of the inner wall.

[0032] In order to adjust the use angle, for example, as shown in Figure 1 , a damping bearing 21 is installed on the outer wall of the connecting shaft 2, and a connecting piece 22 is rotatably installed on the outer wall of the damping bearing 21.

[0033] In use, the damping bearing 21 allows the yarn nozzle body 1 to be rotated or inclined as needed to adapt to different knitting requirements and yarn types. This design improves the flexibility and applicability of the yarn nozzle body 1, enabling the flat knitting machine to knit a wider variety of knitted fabrics. The connecting piece 22 can be connected to an external mounting position, keeping the use position of the overall structure relatively stable.

[0034] In order to achieve precise insertion, for example, as shown in Figure 3 , a fitting groove 26 is formed on one side of the lower end of the outer wall of the connecting shaft 2, and the size of the fitting column 13 is smaller than the size of the inner wall of the fitting groove 26, with the fitting column 13 located inside the fitting groove 26.

[0035] In use, it ensures the close connection between the yarn nozzle body 1 and the connecting shaft 2. This design not only improves the stability of the structure of the yarn nozzle body 1, but also helps to reduce the shaking and displacement of the yarn nozzle body 1 during knitting, thereby improving the knitting precision and quality. The fitting groove 26 and the fitting column 13 can limit the position of the clamping groove 12 and the plug 31, facilitating the alignment of the positions of the clamping groove 12 and the plug 31.

[0036] In order to maintain the use position, for example, as shown in Figure 2 , the connecting cover 24 is elastically connected between the first spring 25 and the limiting ring 23, and the support frame 3 is located inside the connecting cover 24.

[0037] In use, the elastic force of the first spring 25 can limit the use position of the connecting cover 24. When the connecting cover 24 is manually pressed by the worker, the connecting cover 24 comes into contact with the inclined surface of the wedge block 34 and pushes the wedge block 34 and the plug 31 to move horizontally inside the support frame 3 until the wedge block 34 enters the inside of the connecting cover 24 and the plug 31 enters the inside of the clamping groove 12. The connecting cover 24 blocks the wedge block 34, ensuring the stable position of the plug 31 inside the clamping groove 12 and the stable fixation of the use position of the yarn nozzle body 1.

[0038] In order to connect firmly, the size of the plug-in 31 is smaller than the size of the card slot 12, and one end of the plug-in 31 is located inside the card slot 12. Figure 4

[0039] In use, the plug-in 31 can be easily inserted into the card slot 12 and fixed, which simplifies the installation and disassembly process of the yarn nozzle body 1 and improves work efficiency. At the same time, one end of the plug-in 31 is located inside the card slot 12, which ensures the stability and reliability of the yarn nozzle body 1.

[0040] In order to maintain the use position, the size of the plug-in 31 is smaller than the size of the card slot 12, and one end of the plug-in 31 is located inside the card slot 12. Figure 4

[0041] In use, the second spring 33 gives the plug-in 31 an additional fixing and buffering effect. This design not only enhances the stability of the yarn nozzle body 1, but also helps to reduce the risk of loosening and falling of the plug-in 31 during knitting. At the same time, the design of the limiting plate 32 also facilitates the limitation of the moving track of the plug-in 31, so that when the plug-in 31 is expanded by the elastic force of the second spring 33, the wedge block 34 corresponds to the position of the connecting cover 24.

[0042] In order to link movement, the size of the plug-in 31 is smaller than the size of the card slot 12, and one end of the plug-in 31 is located inside the card slot 12. Figure 4

[0043] In use, the wedge block 34 can be pushed by the movement of the connecting cover 24 until the wedge block 34 enters the connecting cover 24, so that the plug-in 31 can be easily slid and fixed in place when inserted into the card slot 12, which simplifies the installation process of the yarn nozzle body 1 and improves work efficiency. At the same time, the contact between the wedge block 34 and the inner wall of the connecting cover 24 also ensures the tight connection and stability of the yarn nozzle body 1.

[0044] In use, the yarn nozzle body 1 is initially connected with the lower end of the connecting shaft 2 through the connecting column 11 thereon. Ensure that the embedded column 13 is accurately inserted into the embedded groove 26 at the lower end of the connecting shaft 2 to achieve initial tight connection.

[0045] ​​​The connecting cover 24 is manually pressed to move downward. The inner wall of the connecting cover 24 will be in contact with the inclined surface of the wedge block 34 and push the wedge block 34 and the plug 31 to move horizontally inside the support frame 3. With the continuous movement of the connecting cover 24, the wedge block 34 will be completely pushed into the connecting cover 24, and at the same time, the plug 31 is also pushed into the clamping groove 12 on the connecting column 11. When the plug 31 is completely in the clamping groove 12, the connecting cover 24 will block the wedge block 34, ensuring that the plug 31 is stable inside the clamping groove 12. At this time, the elastic force of the first spring 25 will keep the position of the connecting cover 24, thereby keeping the plug 31 stable;
