[0016] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0017] Reference Figure 1 , Figure 2 As shown, a new type of knitting needle mechanism for a computer flat knitting machine includes a knitting needle 1, a long stitch 2, and a spring stitch selection pin 3. In this embodiment, the knitting needle 1, the long stitch 2, and the spring stitch selection pin 3 are sequentially inserted into the needle groove of the needle plate from top to bottom, and the lower part of the knitting needle 1 is connected with the upper part of the long stitch 2. The spring stitch selection pin 3 is relatively arranged at the lower outer part of the long stitch 2. The mountain plate is driven by the machine head to slide along the needle plate, so that the spring stitch selection pin 3 slides up and down along the needle groove under the linkage of the mountain plate, so as to press the long stitch 2 into the needle groove.

[0018] In this embodiment, the mountain plate is provided with a weaving unit, a sheet pressing unit, a needle selector, and a needle selection unit. These structures are all existing structures, and this embodiment will not be repeated here.

[0019] Specifically, the upper part of the spring needle selection pin 3 has a spring needle piece 31 extending downward, the lower part of the spring needle piece 31 is in contact with the needle plate, the lower part of the spring needle selection pin 3 has a space-avoiding portion 32 bent toward the needle plate, and the outer lower part of the spring needle selection pin 3 is provided with a lower needle selection piece butt 33, the inner upper end of the spring needle selection pin 3 has a spring front piece butt 34, and the outer upper end of the spring needle selection pin 3 has a spring rear piece butt 35.

[0020] Among them, the lower needle selecting heel 33 of the spring needle selecting foot 3 cooperates with the needle selecting unit of the mountain plate, the front needle selecting heel 34 abuts against the outer side of the long needle foot 2, and the rear needle selecting heel 35 of the spring cooperates with the pressing plate unit of the mountain plate.

[0021] A reinforcing heel 21 is arranged on the upper outer side of the long needle foot 2 to increase the upper strength of the long needle foot 2 and avoid deformation of the upper part of the long needle foot 2.

[0022] Furthermore, a rear heel 24 of the long needle foot is arranged in the middle of the outer side of the long needle foot 2 for cooperating with the knitting unit of the mountain plate, and the lower end of the long needle foot 2 has an elastic end 23 that abuts against the needle plate.

[0023] During specific operation, the machine head drives the mountain plate to move along the needle plate, so that the needle selecting unit of the mountain plate pushes the spring needle selecting foot 3 to rise to the H position, A position or B position of the pressing plate unit, thereby pressing the rear heel 35 of the spring of the spring needle selecting foot 3 through the pressing plate unit, pressing the heel 35 of the needle selecting foot into the needle groove, and using the front heel 34 of the spring of the spring needle selecting foot 3 to press the long needle foot 2, so that the heel of the long needle foot 2 sinks into the needle groove and does not move along the needle moving track of the knitting unit. When the pressing plate unit no longer presses the spring needle selecting foot 3, the spring needle selecting foot 3 resets under the elastic action of the spring needle piece 31, so that the rear heel 35 of the spring of the spring needle selecting foot 35 exposes from the needle groove. Similarly, the long needle foot 2 resets under the elastic action of the elastic end 23, so that the rear heel of the long needle foot 2 exposes from the needle groove and moves along the needle moving track of the knitting unit to enable the knitting needle to perform knitting work.

[0024] In this embodiment, a number of limiting grooves are arranged on the upper part and the clearance part 32 of the spring needle selecting foot 3, so as to cooperate with the steel strip on the needle plate by using the limiting grooves, which not only restricts the spring needle selecting foot from running out of the needle groove, but also ensures the stability of the lifting of the spring needle selecting foot.

[0025] Certainly, the above embodiments are only used to illustrate the technical concept and characteristics of the present invention, and the purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly. It cannot be used to limit the protection scope of the present invention. All modifications made according to the spirit of the main technical solution of the present invention should be covered within the protection scope of the present invention.
