It can realize automated operation through the cylinder and the synchronous belt assembly, reduce manual intervention, and improve the level of automated production.

[0022] In this embodiment, as shown in Figure 3As shown, an inlet port 31 and an outlet port 32 are provided on the left mold 3. A thin groove 33 is provided at the inlet port 31 to facilitate the entry and exit of wires. The thin groove 33 at the inlet port 31 helps to guide the copper wire into the winding shaft.

[0023] In this embodiment, as Figure 2 shown, the synchronous belt assembly 4 includes a motor 41 disposed above the workbench 1 and on one side of the bracket 2.
