[0015] The following is only the preferred embodiment of the present utility model, and the protection scope is not limited to this embodiment. All technical solutions falling within the idea of the present utility model shall belong to the protection scope of the present utility model. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom" and "top", "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0016] As Figure 1 and Figure 3 shown, a low-cost and high-efficiency needle plate includes a substrate 1 and a plurality of inlays 2. The plurality of inlays 2 are located on one side of the substrate 1 and are fixedly connected to the substrate 1 by clamping. The plurality of inlays 2 are parallel and equidistantly arranged. The interval between two adjacent inlays 2 is a needle groove 15, and the needle groove 15 is used to fix the knitting needles.

[0017] The side of the insert piece 2 away from the substrate 1 is the front side. On the front side of the insert piece 2, there are three pressing grooves. From top to bottom, the three pressing grooves are the first pressing groove 3, the second pressing groove 4, and the third pressing groove 5 respectively. On the front side of the insert piece 2, there are also three fixing strips. The three fixing strips are arranged horizontally and are respectively abutted in the three pressing grooves. In order to prevent separation between the pressing grooves and the fixing strips, both the pressing grooves and the fixing strips are set to be similar to the dovetail shape.

[0018] To enhance the stability of the insert piece 2, the first pressing groove 3 is arranged at the uppermost part of the front side of the insert panel, the second pressing groove 4 is arranged below the first pressing groove 3 and is adjacent to the first pressing groove 3. The third pressing groove 5 is arranged at a position slightly lower than the middle of the front side of the insert piece 2. There is a relatively large interval between the third pressing groove 5 and the second pressing groove 4. In this design, the vertical distance between the upper edge of the third pressing groove 5 and the lower edge of the second pressing groove 4 is 75 mm.

[0019] A toothed piece 7 is provided at the top of the substrate 1. A positioning groove 12 is provided on the substrate 1. A positioning rod 13 is inserted into the positioning groove 12. A positioning hole 14 is opened on the toothed piece 7. The positioning rod 13 is inserted into the positioning hole 14 to fix the position of the toothed piece 7.

[0020] The toothed piece 7 includes a head 8, a tail 9, and a stabilizing portion 10. At one end of the tail 9 of the toothed piece 7 away from the head 8, there is a hook portion 11, and one end of the hook portion 11 is bent upward. A cushion portion is provided on the side of the upper end of the insert piece 2 away from the first pressing groove 3. There is a height difference between the rear side edge of the cushion portion and the rear side edge of the insert piece 2, that is, the position of the rearmost side of the cushion portion is more forward than the position of the rearmost side of the insert piece 2. The width of the hook portion 11 is smaller than the width of the tail 9. When the insert piece 2 is fixedly connected to the substrate 1, there is a gap between the rear side of the cushion portion and the substrate 1, and the width of this gap is the same as the width of the hook portion 11. Therefore, when the toothed piece 7 is fixed on the substrate 1 and then the insert piece 2 is fixed on the substrate 1, at this time, the cushion portion of the insert piece 2 can press on the position of the hook portion 11 of the toothed piece 7, so that the hook portion 11 of the toothed piece 7 cannot shake, increasing the stability of the toothed piece 7.

[0021] The head 8 and the tail 9 of the toothed piece 7 are of conventional structures. During installation, the tail 9 is snap-fitted into the needle groove 15 on the front side of the substrate 1. There is an interval between the stabilizing portion 10 and the tail 9. The toothed piece 7 is clamped on the top of the substrate 1 through this interval, so that the stabilizing portion 10 abuts against the rear side wall of the substrate 1. The stabilizing portion 10 of the toothed piece 7 is in the shape of a bent rod. In this application, the upper end of the stabilizing portion 10 is an inclined rod with a slope similar to the rear side of the head 8, and the lower end of the stabilizing portion 10 is a straight rod vertically downward. After being fixed to the substrate 1, the straight rod at the lower end of the stabilizing portion 10 will abut against the rear side wall of the substrate 1, increasing the stability of the toothed piece 7.

[0022] A sinker 6 is also provided on the substrate 1. A rotation hole is formed in the sinker 6, and the sinker 6 is rotatably connected to the positioning rod 13 through the rotation hole. The positioning rod 13 can fix the position of the sinker 6, and the sinker 6 can rotate around the positioning rod 13.

[0023] In this design, the length of the substrate 1 is 165 mm - 170 mm, and the length of the insert 2 is 152 mm - 157 mm. Specifically, the substrate 1 is 168 mm long, and the insert 2 is 155 mm long, with an error range of 1 mm. The commonly used substrate 1 in the prior art is 211 mm long, and the insert 2 is 198 mm long, with an error range of 1 mm. Compared with the existing substrate 1 and insert 2, the specifications adopted in this application are shortened by about 40 mm, which can greatly reduce the cost of raw materials and does not affect normal knitting. Since both the insert 2 and the substrate 1 are shortened, the time required for needle exit during the knitting process is also shortened, which can improve the efficiency of needle exit.

[0024] In the specific embodiments described above, the technical problems solved, technical solutions, and beneficial effects of the present utility model have been further described in detail. It should be understood that the above description is only for the specific embodiments of the present utility model and is not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
