The feeding plates 5 each have a neck 5 and the neck 5 Ο 1 is intended to be placed on the cross bar 3 2 下 of the pushing member 3 2 to make the feeding plate 50 and the linkage mechanism 3 The pusher 3 2 is connected. Each of the tops of the yarn feeding plates 50 is provided with an elastic member 53 which can pull the yarn feeding plate 5 Q to swing upward and reset. The yarn feeding rods 5 1 / 7 are not fixed to the yarn feeding plates 5 , so that the yarn feeding rods 5 1 are connected to the yarn feeding plates 50 to drive the yarn feeding rods 5 1 by the yarn feeding plates 5 Q. . ▲ ^ The sliding members 52 are slidably sleeved on the yarn feeding rods 5, and the first convex portion 5 2 1 and the second convex portion are respectively disposed on the front side and the rear side of the special sliding member 5 2 . 5 2 2, the first convex portion 5 21 and the second convex portion 5 2 2 respectively correspond to the lower end of the push-down member 3 2 and the through hole 3 ! 1 of the pull-up member 3 i, so as to facilitate the riding with the push-down member 3 2 The piece 5 2 is downward (four), and the slider 5 2 is pulled upward by the pull-up member 3 1 . 1362438 Although the selected pin of the needle selector 8 is placed on the convex portion 1 1 3 of the first link 1 1 1 of the color selection plate 1 according to the set time, the first link 1 1 end of the first link 1 1 That is, the first hook portion 1 1 4 of the first link 1 1 1 is lowered by a predetermined height, and the first hook portion i 2 4 and the first hook portion 1 of the second link 2 are lowered. A gap is formed between the two, so that the second hook portion 1 1 ^ is then released, the first hook portion 114, and the second portion 16 of the lower end of the second link 112 can be pushed by the elastic member i 5 The slab 2 touches the back-segment distance. Since the elastic member 5 pushes the pusher plate 12 toward the color selection plate, the 'pushing portion i 2 i of the push plate i 2 is moved to the predetermined position' and can be pushed by the first plurality of levers 6 to make the push Gauze! 2 moving downward, and the top sill portion 1 16 of the second connecting rod 1 1 2 falls on the groove 1 2 2 IV, and the yarn plate 1 2 can link the feeding plate 50 and the feeding rod 5 1The yarn will be hooked to the yarn feeder, and the colored yarn will be woven and weaved. The amount of the pusher plate 12 and the yarn feeding plate 50: „= can be reset upward. The needle selection of the needle selector 8 is set. When the good timing is pressed against the first:!, i 1 3 of the other board 1 1 , the top-side portion 116 of the other-selective color-pushing/retracting is retracted, so that the pushing portion 121 is moved to the predetermined position. However, H can move the other push plate 12 downward, and the other 2 === the yarn feeding plate 50 to which it is connected and the yarn feeding = ▼ to " yarn yarn on the yarn mouth, so that the other yarn can be colored The line is lowered to the bottom of the push-up member 132. The top end of the pusher member 3 is connected to the lower end of the pusher member 3 2 to move the pull-up member 31 downward. When the push-down member 3==, the first convex portion 5 2 1 of the sliding member=2 of the previous yarn feeding rod 5 is pushed forward, so that the sliding member 52 moves downward, The yarn feeding portion 5 1 1 at the front end of the second yarn feeding yarn Ϊ 5 1 is used to cut the hooked back = i to return the yarn feeding rod 5 1 and the sliding member 5 2 Action. When the 1 ^ 2 is moved upwards, the perforation 3 1 1 of the pull-up member 3 1; the second convex portion 5 2 2 of the slider 5 2 of the upper sliding sleeve is inserted, so that the slider 5 2 and the upper portion Pulling member 2 The second convex portion 522 on the rear side of the sliding member 52 can move the 1 to open the arboring 22 to facilitate the other feeding rod 5 to bring the colored yarn to the yarn feeding port. The present invention is mainly used in the first pressing bar 6, the first-rolling member 61, 71, the rolling member is a rolling element such as a pivoting roller, and the rolling member 6^, 7H i is =Lin or 7 2 pivoted in the first a pressing rod 6, a - knife region ά 6 2 7 (four) moving on the upper edge of the first 6 Wi is higher than the first rod rolling member so that the rolling members 6 !, 71 contact the top surface of the tooth, 1, the second Road 9 2. (4) Wheels on the 9th brother of a track 9 The gear plate 9 is set on the base 1 mast 7 square, the bottom of the gear plate 9 1 - the road 9 2, the first deacon gi, flute - 込9 above the first pressure bar 6, the second pressure bar 7 -2 respectively, the second command road 9 2 can follow the rotation of the gear plate 9 to perform f ^, the first command line 9 i, the second command line 9 2 respectively push the rolling elements 6 1 and 7 1 of the 1st - 11362438 rod 7 (as shown in the fourth figure) In order to utilize the control of the first pressing rod 6, the second pressing rod 7, and the needle selector 8, the knitting needle can be used as a yarn feeding operation for the colored yarn, so that the knitted fabric has a different color pattern effect. The invention is provided with rolling elements 6 1 , 7 1 at the upper ends of the first pressing rod 6 and the second pressing rod 7 of the color changing head, and the rolling elements 6 1 , 7 1 can be used for rolling contact with the first rail 9 1 The second rail 9 2, because the first pressing rod 6 and the second pressing rod 7 are operated by the rolling contact between the first lane 9 1 and the second lane 9 2 , the first pressing rod 6 The second pressing rod 7 is less likely to be worn between the first support rail 9 1 and the second rail 9 2 , so that the damage rate of the components is reduced, the service life is increased, and the replacement is not necessary, and the use is convenient. The above is only the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Therefore, the equivalents of the present invention and the equivalents of the drawings are all included in the present invention. Within the scope of protection, it is given to Chen Ming.
