[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 A directional yarn guide mechanism of a garment fabric flat knitting machine comprises a connecting plate 1 and a pulley 2 arranged on the surface thereof, wherein a storage groove is arranged in the connecting plate 1, and two moving blocks 3 are slidably connected to the inner side wall of the storage groove, which are used to drive the support block 4 to move, and a guide rod 11 is arranged between the two moving blocks 3, which is used to keep the moving block 3 moving linearly, and the two ends of the guide rod 11 slide through the two moving blocks 3 and are fixedly connected to the inner side wall of the storage groove;

[0023] In this embodiment, a bidirectional screw 7 is provided in the storage groove, which is used to drive the moving block 3 to move. One end of the bidirectional screw 7 passes through the two moving blocks 3 and the connecting plate 1 in sequence and is fixedly connected with a movable disk 10, which is used to facilitate the user to rotate the bidirectional screw 7. The bidirectional screw 7 and the connecting plate 1 are rotatably connected, and the bidirectional screw 7 and the moving block 3 are threadedly connected. A clamping rod 12 is inserted at a side of the movable disk 10 away from the connecting plate 1 and close to the edge, which is used to cooperate with the clamping hole to prevent the movable disk 10 from loosening. The clamping rod 12 and the movable disk 10 are threadedly connected. A plurality of clamping holes corresponding to the clamping rod 12 are distributed in an annular shape on the outer wall of the connecting plate 1. A handle 13 is fixedly connected to the outer wall of the movable disk 10, which is used to facilitate the user to hold and rotate the movable disk 10;

[0024] In this embodiment, a support block 4 is fixedly connected to the outer wall of the moving block 3 for supporting the card block 5. An opening corresponding to the support block 4 is provided on the surface of the connecting plate 1. One end of the support block 4 slides through the opening. A card block 5 is fixedly connected to the side of the support block 4 close to the pulley 2 for cooperating with the card slot to lock and unlock the position of the support column 6. A through hole is provided in the pulley 2. A support column 6 is inserted in the through hole for supporting the pulley 2. The support column 6 and the through hole are rotatably connected. Both ends of the support column 6 respectively pass through the through holes. Both ends of the support column 6 are provided with card slots corresponding to the card block 5. The end of the card block 5 away from the support block 4 slides and extends into the card slot.

[0025] In this embodiment, a bearing 8 is fixedly sleeved on the pillar 6 to reduce the resistance of the pulley 2 during rotation and improve the smoothness of rotation. The outer wall of the bearing 8 is fixedly connected to the inner wall of the through hole. Two retaining rings 9 are fixedly sleeved on the pillar 6 to prevent debris from entering the through hole. The two retaining rings 9 are respectively located on both sides of the pulley 2.

[0026] In this embodiment, first manually rotate the movable disk 10 to drive the bidirectional screw 7 to rotate, and the bidirectional screw 7 drives the two movable blocks 3 to move in relative or opposite directions through the action of threaded engagement (controlled by the direction in which the user rotates the movable disk 10). When the two movable blocks 3 move in opposite directions, the movable block 3 drives the support block 4 to move, and the support block 4 drives the card block 5 to move, so that the card block 5 is disengaged from the card slot, and the position of the pillar 6 can be unlocked. At this time, the pulley 2 can be removed, and when the two movable blocks 3 move in relative directions, the movable block 3 drives the support block 4 to move, and the support block 4 drives the card block 5 to be inserted into the card slot, so that the position of the pillar 6 can be locked. At the same time, the card rod 12 is screwed into the card hole to prevent the movable disk 10 from loosening.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
