[0022] Please see Figure 3 To quickly fix the pusher triangle 9 onto the return guide block 7, the mounting mechanism 8 includes a mounting shell 81. The rear end of the mounting shell 81 is fixedly connected to both sides of the front end of the return guide block 7. Limiting grooves 82 are provided on both sides of the inner wall of the mounting shell 81. Insertion posts 83 are provided on the inner wall of the mounting shell 81. A connecting plate 84 is fixedly connected to the upper end of the insertion post 83. A storage groove 85 is embedded and connected to both sides of the lower end of the insertion post 83. A second spring 86 is fixedly connected to one side of the inner wall of the storage groove 85. A displacement block 87 is fixedly connected to one end of the second spring 86. A limiting block 88 is fixedly connected to the other end of the displacement block 87. An end cap 89 is bolted to the lower end of the insertion post 83. The inner walls of the mounting shell 81 are embedded and connected to the outer walls of the limiting grooves 82. The inner wall of the mounting shell 81 is inserted into the outer wall of the insertion post 83. The lower end of the connecting plate 84 is fixedly connected to the upper end of the insertion post 83, and the front end of the connecting plate 84 is fixedly connected to the top of the rear end of the pusher triangle 9.

[0023] To quickly and reliably fix the pusher triangle 9 onto the return guide block 7, the rear end of the mounting shell 81 is firmly connected to the front sides of the return guide block 7 by welding or bolting, ensuring the stability of the overall structure. A pair of limiting grooves 82 are symmetrically arranged on both sides of the inner wall of the mounting shell 81 to guide and constrain the movement trajectory of the internal limiting blocks 88. A vertical insertion post 83 is installed at the center of the inner wall of the mounting shell 81. A connecting plate 84 is fixedly connected to the upper end of the insertion post 83 by welding. The connecting plate 84 not only serves a connecting function but also enhances the overall structural integrity. Embedded storage grooves 85 are provided on both sides of the lower end of the insertion post 83. A second spring 86 is fixedly installed on one side of the inner wall of the storage groove 85, and the other end of the second spring 86 is fixedly connected to a movable displacement block 87. The displacement block 87 is located within the spring 86. Under the action, it can achieve elastic displacement. Its other end is further fixed to a limiting block 88. The limiting block 88 cooperates with the limiting groove 82 on the inner wall of the mounting shell 81 to achieve accurate positioning and reliable locking of the insert 83. The lower end of the insert 83 is also connected to an end cap 89 by a thread. The end cap 89 is set to facilitate disassembly and maintenance and prevent internal components from falling off accidentally. The inner walls of the mounting shell 81 and the outer walls of the limiting groove 82 are embedded to ensure the accuracy and tightness of the fit. At the same time, the inner wall of the mounting shell 81 and the outer wall of the insert 83 are connected by a plug-in method, which facilitates assembly and ensures smooth relative movement. The lower end of the connecting plate 84 is fixed to the upper end of the insert 83, and the front end of the connecting plate 84 is also fixed to the rear end top of the push pin triangle 9 by welding, thereby realizing the quick installation and fixation of the push pin triangle 9.

[0024] Working principle: First, by pulling the pull plate 67, the slide rod 65 moves the movable block 64 within the movable groove 63, and the spring 66 is compressed, thereby releasing the clamping force on the center guard 5, facilitating the quick installation or removal of the center guard 5. After the center guard 5 is in place, the pull plate 67 is released, and the rebound force of the spring 66 pushes the movable block 64 back to its original position, achieving a stable clamping of the center guard 5. Next, the pusher triangle 9 is assembled with the insert post 83 through the connecting plate 84. When the insert post 83 is inserted into the inner wall of the mounting shell 81, the limiting block 88 is elastically displaced along the receiving groove 85 under the action of the spring 86 until the limiting block 88 and the limiting groove 82 are fully engaged, completing the fixation of the pusher triangle 9. The end cap 89 not only facilitates subsequent maintenance but also effectively prevents internal components from loosening or falling off, ensuring the stability of equipment operation. The entire installation process is simple to operate and has a compact structure, which can significantly improve assembly efficiency and reduce error rate, thereby improving weaving accuracy and the smoothness of equipment operation.

[0025] Then, through the cooperation of the connecting mechanism 6 and the installation mechanism 8, the problem of difficulty in ensuring the accuracy of the triangular template during the assembly process of traditional flat knitting machines can be effectively solved. The inclined surface 62 in the connecting mechanism 6 can guide the central guard 5 to be positioned quickly, while the sliding cooperation between the movable groove 63 and the movable block 64 ensures the uniform distribution of clamping force and avoids loosening or displacement caused by uneven force. At the same time, the precise cooperation between the limiting groove 82 and the limiting block 88 in the installation mechanism 8 further improves the installation accuracy of the push pin triangle 9, making the entire template more stable during operation and reducing the occurrence of jamming. In addition, the elastic setting of the second spring 86 not only enhances the locking effect of the limiting block 88, but also provides convenience for subsequent disassembly and maintenance, thereby achieving the unity of lightweight and high maintainability of the equipment. The above is the working process of the entire device, and the contents not described in detail in this specification are all existing technologies known to those skilled in the art.

[0026] 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.
