[0024] The utility model is now further described in conjunction with the accompanying drawings and specific embodiments.

[0025] refer to Figure 1-4 The embodiment of the utility model discloses: a needle dial with an auxiliary unhooking piece dedicated to the needle dial, comprising a needle dial 1 and a sinker 2 arranged on the needle dial 1, wherein the sinker 2 comprises a sheet body 21, one end of the sheet body 21 is provided with a sheet throat 22 cooperating with a hook needle, the other end of the sheet body 21 and the needle dial 1 are provided with a swinging device for the sheet body 21 on the needle dial 1, and the back of the sheet body 21 is provided with a sheet heel 3 cooperating with a triangle.

[0026] Specifically, the swing fulcrum device is a support joint 25 extending outward from the end of the sheet body, and the support joint 25 is located at the other end of the sheet throat 22. The end of the support joint 25 is arranged in an arc shape, and the needle disk 2 is provided with a movable groove 4 for the support joint to penetrate. The support joint 25 is arranged in the movable groove 4, and an anti-slip protrusion 5 extends from one end of the entrance of the movable groove 4. Vertical vertical surfaces 26 are provided on two side surfaces of the support joint 25 so that the support joint 25 can avoid the anti-slip protrusion 5 and be stuck in the movable groove 4.

[0027] When the sinker 2 is to be installed, the support joint 25 is placed in a vertical plane 26 perpendicular to the movable groove 4, and then the support joint 25 is directly placed in the movable groove 4, and then the support joint 25 is rotated so that the spherical surface of the support joint 25 resists the inner wall of the movable groove 4, and the installation of the sinker 2 on the needle disk 1 is completed. The sinker 2 is directly installed on the needle disk 1, which is not only simple and fast to install, but also does not require a special annular ring and other parts for installation. It is not only simple to install, but also reduces the application of parts and saves installation costs. Moreover, after the support joint 25 is turned over, the arc surface forms a rotating hinge fulcrum, and the existence of the anti-slip protrusion 5 makes the opening of the movable groove 4 narrower, so that the support joint 25 is limited to move in the movable groove 4, and will not slip out of the movable groove 4, avoiding the sinker from jumping upward and hitting the needle plate or producing floating or skipped lines, thereby ensuring the quality of the fabric and improving production efficiency.

[0028] In order to improve the weaving precision, the thickness of the front end of the sheet body 21 at the sheet throat 22 is smaller than the thickness of the rear end.

[0029] In order to limit the downward swing amplitude of the sinker and prevent the sinker 2 from interfering with the needle disk 1 and affecting the swing, a top plate 27 is extended downward from the sheet body 21 to resist the needle disk 1. A swing channel is provided between the top plate 27 and the support joint 25. The swing channel is located at the contact position with the needle disk 1 and is provided with a first avoidance chamfer 23 to facilitate the swing of the sheet body 21. When the sinker swings downward and is driven to a predetermined position, the top plate 27 directly contacts the needle disk 1, so that it will not continue to swing, which is conducive to ensuring the knitting accuracy. The first avoidance angle 23 can prevent the sinker from interfering with the needle disk 1 when it rises, so that the sinker 2 can swing upward stably.

[0030] In order to allow the sinker to swing back downward better and prevent the needle disk 1 from interfering, the needle disk 1 is provided with a second avoidance chamfer 6 at the position of the movable groove 4 to facilitate the swing of the sheet body 21.
