Example two
A working method of a novel needle selecting and discharging structure comprises the following steps:
s100, the bottom plate 1 moves towards a first direction.
In S100, the first direction coincides with the direction in which the first stitch pushing cam 3 faces the second stitch lifting cam 52.
And S200, lifting all the needle selection stitches by the second needle lifting cam 52 according to the first direction.
And S300, the selector 2 presses down the stitch which does not need to pass through the selection of the No. 1 pre-selection track 8 in the first direction.

Specifically, the second raising cam 52, the selector 2, and the first pushing cam 3 in steps S200, S300, and S400 move synchronously with the bottom plate 1 in step S100. The second needle lifting cam 52, the needle selector 2 and the first needle pushing cam 3 act according to specific requirements, the first needle lifting cam 51 is always kept in an operating state, and the second needle pushing cam 4 is in a non-operating state. Generally, in the front of step S100, the three steps S200, S300 and S400 are started from first to last in sequence; in the middle stage of the step S100, the three steps S200, S300, and S400 are performed synchronously, and in the later stage of the step S100, the three steps S200, S300, and S400 are sequentially performed from the beginning to the end.
Similarly, the first raising cam 51, the selector 2, and the second pushing cam 4 in steps S700, S800, and S900 move synchronously with the bottom plate 1 in step S600. The first needle lifting cam 51, the needle selector 2 and the second needle pushing cam 4 act according to specific requirements, while the second needle lifting cam 52 is always in an operating state, and the first needle pushing cam 3 is in a non-operating state.
