DETAILED DESCRIPTION

[0036] The following description is only a preferred embodiment of the present application, the protection scope is not limited to the embodiment only, any technical solution falling within the concept of the present application should fall within the protection scope of the present application. Identical parts are denoted by identical reference numerals. It should be noted that the words “front”, “rear”, “left”, “right”, “upper” and “lower” used in the following description refer to the directions in the drawings, and the words “bottom” and “top”, “inner” and “outer” refer to the directions towards or away from the geometric center of a particular part. In the design of the present application, the moving direction of the needle assembly of the knitting process is from left to right.

[0037] As shown in Figures 1 to 8 Fig. 1, a high-efficiency stable flat knitting machine cam plate comprises a plurality of knitting systems and a needle assembly 7 used in conjunction with the knitting systems. The knitting systems comprise, from bottom to top, a selection zone 1, a position plate zone 2 and a knitting cam zone 3. The needle assembly 7 comprises, from bottom to top, a selection piece 71, a forked needle 72, a connecting long needle 73 and a knitting needle 74. The upper end of the connecting long needle 73 is connected to the knitting needle 74, and the lower end of the connecting long needle 73 is suspended. By pressing the long needle, the long needle can be rotated around the top end. The forked needle 72 is provided with a forked needle butt 75, and the connecting long needle 73 is provided with a long needle butt 76. The forked needle butt 75 moves in the position plate zone 2, and the long needle butt 76 moves in the knitting cam zone 3. When the forked needle butt 75 is pushed out by the position plate zone 2, the forked needle 72 will press the connecting long needle 73, causing the connecting long needle 73 to drive the long needle butt 76 to also deviate outward. After the long needle butt 76 deviates outward, it no longer contacts the knitting cam zone 3, i.e. no longer moves along the track in the knitting cam zone 3.

[0038] The selection piece 71 cooperates with the selection zone 1. The selection piece 71 and the selection zone 1 are existing designs, and no changes are made to the selection zone 1 and the selection piece 71 in the present application.
