A slider is provided between the needle head and the needle body. The slider is slidably arranged between the needle head and the needle body. The top edge of the slider is in contact connection with the needle head. A first needle foot is provided on the slider, and a second needle foot is provided on the needle body.

[0007] By adopting the above technical solutions, the first needle foot and the second needle foot are respectively installed in the corresponding tracks of the triangular base. The top edge of the slider abuts against the bottom surface of the needle head to keep the needle head stable. When the loop needs to be shed after knitting, the slider moves downward under the drive of the triangular base. At the same time, since the needle head loses the support of the slider, the needle head tilts backward, and the loop can be unhooked from the needle head. Since there is no need to set a needle opener, the structure is simplified and loop shedding is facilitated.

[0008] In a preferred example of the utility model, it can be further configured as: the needle head includes a hook head and a needle body, and the hook head is provided on the needle body.

[0032] The present utility model will be further described in detail below with reference to the accompanying drawings. Embodiment

[0033] Referring to Figure 1 , a circular weft knitting machine disclosed by the present utility model includes an upper needle disc and a lower cylinder, including an upper disc 2, a needle cylinder 3 disposed below the upper disc 2, a yarn feeding mechanism, and a knitting needle assembly 1. The knitting needle assembly 1 is disposed around the needle cylinder 3, and the knitting needle assembly 1 is disposed facing away from the needle cylinder 3.

[0034] Reference Figures 1-4 As shown in Figures 1-4 , the knitting needle assembly 1 includes a needle head 11 and a needle shank 12. The opening side of the needle head 11 is rotatably connected to the needle shank 12 through a rotating shaft. A slider 13 is provided between the needle head 11 and the needle shank 12. The slider 13 is slidably arranged between the needle head 11 and the needle shank 12. A region for the slider 13 to slide up and down is provided between the needle head 11 and the needle shank 12. The top edge of the slider 13 is in contact connection with the needle head 11. A first stitch foot 14 is provided on the slider 13, and a second stitch foot 15 is provided on the needle shank 12.

[0035] The first stitch foot 14 and the second stitch foot 15 are respectively installed in the corresponding tracks of the cam holder. The top edge of the slider 13 abuts against the bottom surface of the needle head 11 to keep the needle head 11 stable. When it is necessary to cast off the loop during knitting, the slider 13 moves downward under the drive of the cam holder. At the same time, since the needle head 11 loses the support of the slider 13, the needle head 11 tilts backward, and the loop can be unhooked from the needle head 11.

[0036] The needle head 11 includes a hook head 111 and a needle body 112. The hook head 111 is arranged on the needle body 112. The needle body 112 is arranged in a right triangle structure. The two acute angle vertices of the needle body 112 are respectively connected to the tail of the hook head 111 and the top end of the needle bar 121. The needle body 112 is arranged in a triangular structure, which can enhance the overall structural stability of the needle body 112.

[0037] A needle bar 121 is provided on the needle shank 12. The needle bar 121 is located on the side of the needle shank 12 facing the opening of the needle head 11. The side of the needle body 112 facing the opening of the needle head 11 is rotatably connected to the top end of the needle bar 121. A limiting member 123 for restricting the needle head 11 from flipping to the front side of the needle shank 12 is provided on the needle bar 121. The needle bar 121 includes two rod pieces 122. The limiting member 123 is a sealing edge provided at the top ends of the two rod pieces 122. The sealing edge closes and connects the top ends of the two rod pieces 122. The connection part at the top ends of the two rod pieces 122 is in a bevel shape and fits with the bevel of the needle body 112. The first stitch foot 14 includes two foot pieces, and the needle bar 121 is located between the two foot pieces.

[0038] Since there is a region for the slider 13 to move up and down between the needle shank 12 and the needle head 11, the needle shank 12 and the needle head 11 are connected through the needle bar 121. And since the two rod pieces 122 are closed at the top ends, the needle body 112 is restricted in a certain activity region, preventing the needle head 11 from flipping over the needle shank 12.

[0039] The top of the slider 13 is arranged on a first slope surface. The first slope surface is inclined downward from the back of the knitting needle to the front of the knitting needle. The bottom edge of the needle head 11 is arranged as a second slope surface that fits with the first slope surface.

[0040] The first slope surface and the second slope surface can increase the contact surface between the slider 13 and the needle head 11, and enhance the stability of the support of the slider 13 on the needle head 11.

[0041] A limiting rod 16 is provided on the side of the needle body 12 facing away from the opening side of the needle tip 11, and the limiting rod 16 extends to the back of the needle tip 11.

[0042] When the slider 13 moves downward, the needle tip 11 flips backward, and the coil is further unhooked from the needle tip 11 due to the block of the limiting rod 16.

[0043] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
