AI Technical Summary
The existing tongue needles have a relatively large needle body thickness, which results in insufficient rigidity of the insert, making it easy for the needle to collide, the hook to break, or the needle to flip and come off the loop.
The design incorporates a spring-loaded tab, which enhances the strength of the hook and the tab by installing a spring and a boss at the front end of the needle bar. The design of the recessed and protruding parts further enhances the rigidity of the insert, and the snap-fit structure of the connecting components ensures stable movement.
The strength of the tongue needle and the rigidity of the insert have been improved, reducing the occurrence of broken hooks and missed needles during needle flipping, thus improving the quality of needle flipping.
