The utility model discloses a kind of wire guiding devices of hosiery machine, belong to the technical field of socks processing, including the fixed component for fixing spindle, further including the moving assembly for driving yarn spindle reciprocating motion up and down, further including the adjusting component for adjusting yarn tension;The fixed component includes center tube, the center tube is inserted in yarn spindle middle and with yarn spindle sliding fit;The utility model is rotated by setting rotary disc, simple structure, it is convenient and practical, yarn spindle can be driven to rotate with center tube when external force is pulled, realize stable wire supply, and by setting adjusting component, the friction between the abutting block and rotary disc can be adjusted, so as to realize the adjustment to silk thread tension, and avoid damage to silk thread, and by setting moving assembly, yarn spindle can be driven to move up and down when wire supply, so that wire outlet position is always horizontal with wire guide ring, avoid silk thread up and down swing, simultaneously reduce the friction between silk thread and wire guide ring.

This utility model belongs to the field of trolley technology, and specifically relates to a trolley that facilitates straight-line travel. It includes a balance scooter and a trolley body, connected by a connecting frame. The connecting frame is detachably connected to the trolley body and rotatably connected to the balance scooter. The balance scooter has a positioning groove, and the connecting frame has a positioning element and an elastic element. The elastic element drives the positioning element to engage with the positioning groove, fixing the balance scooter and the connecting frame relatively, thus allowing the trolley to maintain straight-line travel or maintain a certain angle of rotation. Under external force, the positioning element can move relative to the positioning groove, allowing the balance scooter and the connecting frame to rotate relative to each other, thus enabling the trolley to turn flexibly. The purpose of this utility model is to provide a user-friendly trolley that facilitates straight-line travel.
