Among them, the first wire guide tube 3, the conveyor 7, and the second wire guide tube 6 are all technical features disclosed in the prior art. The conveyor 7 is mainly composed of a rotating shaft, a driving gear, a driven gear, and a servo motor. The second wire guide tube 6 is composed of a wire inlet and a conduit. Therefore, as well-known structural features, the present case does not introduce too much about the wire feeding principle, the using process, and the detailed structural composition of the cooperation between several groups of components.

[0020] Furthermore, referring to Figure 1 and Figure 2 As shown, it is worth noting that screws 8 are threadedly penetrated through the four corners of the mounting plate 4, and threaded fixing holes adapted to the screws 8 are provided on the bracket 1;

[0021] Through the arrangement of the screws 8 and the threaded fixing holes, when the mounting plate 4 is to be installed on the bracket 1, rotate the screws 8 so that the screws 8 are threadedly screwed into the threaded fixing holes. In this way, by using the threaded structure, the mounting plate 4 can be fixed on the bracket 1 to ensure the stability of the second wire guide tube 6 during the wire threading process.

[0022] Furthermore, referring to Figure 2 As shown, it is worth noting that a synchronous driving component is arranged among the four groups of screws 8;

[0023] The synchronous drive component includes four groups of rotating shafts 10 vertically arranged on the surface of the mounting plate 4 and rollers 11 tightly sleeved on the rod bodies of the rotating shafts 10.

One end of the screw 8 is fixed with a transmission gear 9 meshing with the belt body of the toothed belt 12;

[0024] Through the setting of the synchronous drive component, simply push and pull the toothed belt 12, so that the toothed belt 12 operates under the action of the four groups of rollers 11 and synchronously meshes with the transmission gears 9 on the four groups of screws 8.
