钩编机用针件是钩编机的核心成圈元件，主要为弹簧针。其特点是针杆末端具有弯曲的针钩，无活动针舌，依靠压板或纱线张力控制针口的开启与闭合。该针件通过精准的垂直往复运动，配合导纱、沉降等机件，完成垫纱、勾纱、成圈及脱圈过程，专用于高效编织弹性饰带、绳索、网格等狭幅或特殊立体结构的织物，是窄幅织带领域的关键执行部件。

Crochet Machine Needle Parts are core loop-forming elements of crochet machines, primarily spring needles. Characterized by a curved hook at the needle tip and no movable latch, they rely on a presser foot or yarn tension to control the opening and closing of the hook. Through precise vertical reciprocating motion and coordination with yarn guiding and sinking elements, these needles complete yarn laying, hooking, loop formation, and knock-over. They are specifically used for efficiently knitting elastic trims, cords, meshes, and other narrow or special three-dimensional fabrics, serving as key execution components in the narrow fabric weaving sector.
