[0047] The wire clamp consists of a first vertical plate 204, a second vertical plate 210, and an arc-shaped connecting section 209 at the upper end, which are parallel to each other. When the wire clamp is locked on the wire guide rod 201, the first vertical plate 204 and the second vertical plate 210 are tightly fitted to the two side walls of the wire guide rod 201, respectively. The length of the second vertical plate 210 is greater than the length of the first vertical plate 204. A wire guide hole 207 is provided at the lower end of the second vertical plate 210. The yarn can be guided by passing the wire through the wire guide hole 207.

[0048] The first vertical plate 204 has a first folded edge 205 at its lower end, and the second vertical plate 210 has a second folded edge 206 at its lower end. The first folded edge 205 and the second folded edge 206 form a V-shaped flare, and a wire hole 207 is provided on the second folded edge 206.

[0049] For easy clamping, the lower end of the first vertical plate 204 is provided with a first folded edge 205, and the lower end of the second vertical plate 210 is provided with a second folded edge 206. The first folded edge 205 and the second folded edge 206 form a V-shaped flare, which makes it easier for the wire clamp to be inserted into the wire guide 201 from above. The wire guide hole 207 is provided on the second folded edge 206.

[0050] Furthermore, for ease of clamping, an extension section is provided at the lower end of the first vertical plate 204, and a second folded edge 206 is provided at the lower end of the second vertical plate 210.

[0052] To ensure vertical clamping stability and prevent the wire clamp from detaching from the guide rod 201, an arc-shaped limiting edge 203 is provided on the upper part of the guide rod 201. The arc-shaped limiting edge 203 is wider than the guide rod 201, and the arc-shaped connecting section 209 cooperates with the arc-shaped limiting edge 203. The distance between the first vertical plate 204 and the second vertical plate 210 is smaller than the width of the guide rod 201, so that when the wire clamp is clamped on the guide rod 201, it can be interference-fitted with the guide rod 201, and the first vertical plate 204 and the second vertical plate 210 form a holding force on the guide rod 201.

[0053] To ensure stable lateral clamping and allow the wire clamp to be adjusted in the lateral direction of the guide bar 201, vertical limiting strips 202 are evenly arranged on one or both sides of the guide bar 201. The spacing of the limiting strips 202 is adapted to the width of the wire clamp. When the wire clamp is clamped between the limiting strips 202, it will be blocked by the limiting strips 202, thus preventing the wire clamp from moving laterally. The even arrangement of multiple limiting strips 202 can form a continuous clamping position. By clamping the wire clamp into different clamping positions, the lateral position adjustment of the guide clamp can be completed.

[0054] A metal ring 208 is provided at the wire hole 207.

[0055] To save costs, plastic can be used for one-piece molding. In order to allow the yarn to pass smoothly through the thread guide hole 207, a metal ring 208 can be set at the thread guide hole 207 to form a smooth guiding surface and prevent the yarn from getting stuck due to wear.
