For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0032] Please refer to the instruction manual Figure 1 To Attachment Figure 7 As shown, the utility model is a sinker driving device of a flat knitting machine, including a track for driving the sinker to move up and down, the track is composed of a lower eyebrow strip 1, an upper eyebrow strip 2, a limiting triangle plate 31 and an anti-hanging triangle 4, the upper eyebrow strip 2 and the limiting triangle 3 are fixedly connected to the eyebrow plate base 5, when the machine head moves laterally, the lower eyebrow strip 1, the upper eyebrow strip 2, the limiting triangle plate 31 and the anti-hanging triangle 4 push the sinker to move to clamp the coil and remove the coil.

[0033] A slideway 51 is provided on the eyebrow board base 5, and a plurality of lower eyebrow strips 1 move back and forth along the direction of the slideway 51. As a preferred embodiment, the number of lower eyebrow strips 1 is two, the anti-hanging eye triangle 4 is located in the middle of the up and down moving track of the sinker, and the two lower eyebrow strips 1 are respectively located on both sides of the anti-hanging eye triangle 4, and each lower eyebrow strip 1 corresponds to two slideways 51. A roller 2 11 is installed on the lower eyebrow strip 1, and the lower eyebrow strip 1 is slidably connected to the eyebrow board base 5 via the roller 2 11. The two slideways 52 ensure the stability of the lower eyebrow strip 1 during movement.

[0034] The anti-lifting triangle 4 is slidably connected to the limiting triangle plate 31. Specifically, a slideway four 52 is provided on the limiting triangle plate 31 for facilitating the sliding of the anti-lifting triangle 4. The anti-lifting triangle 4 moves back and forth along the direction of the slideway four 52. The limiting triangle plate 31 is integrally formed with a limiting triangle 3. The limiting triangle 3 and the anti-lifting triangle 4 are arranged corresponding to each other. The push plate 6 is linked with the anti-lifting triangle 4 to slide. A slideway five 53 for horizontal sliding of the limiting triangle plate 31 is provided on the eyebrow plate bottom plate 5. When the limiting triangle plate 31 slides horizontally, the anti-lifting triangle 4 is linked to move horizontally together. When the machine head moves laterally, the combination needle on the machine tool pushes the limiting triangle plate to a suitable position to clamp the coil and de-wire. In a preferred embodiment, the limiting triangle 3 is located in the middle of the upper and lower moving tracks of the sinker. There are two limiting triangles 3, and the two limiting triangles 3 are arranged in a mirror image so as to better cooperate with the anti-lifting triangle 4.
