It should be noted that the parts not described in detail in this application are all prior art.

[0026] The clamping mechanism 4 has a clamping state and a loosening state. In the loosening state, the piston rod of the cylinder 42 retracts, and a guide space for the copper strip to pass through is provided between the upper pressure plate 45 and the lower pressure plate 44, so that the copper strip can pass between the upper pressure plate 45 and the lower pressure plate 44.
