[0023] The following is a detailed description of the specific settings and functions of this embodiment. Through the settings between the lower pressure seat 3, the upper pressure seat 4 and the inner pressure plate 15, when two bare copper wires are docked, the ends of the two bare copper wires are placed in the discharge trough 14, and the ends are located in the inner pressure plate 15. By tilting the ends of the inner pressure plate 15, the bare copper wire can be restricted. Then the No. 1 hydraulic cylinder 8 is extended to make the mounting plate 5 contact with the upper pressure seat 4, and the bare copper wire is squeezed and fixed between the two inner pressure plates 15 for docking and fixing. A distance must be left between the end and the middle protrusion 16 to ensure that the copper wire can fill the inner pressure plate 15 when deformed, thereby ensuring the strength of the connection. In this way, the loss of bare copper wire can be reduced. At the same time, it is simple to use and improves processing efficiency. Through the setting of the outer protrusion 17, the outer side of the wrapped copper wire can be exposed to the outer protrusion 17 to determine the segmented position and ensure that the length of each coil of copper wire is relatively small.
