The structure is simple and the control is convenient, and no precise control device is required to realize equal feeding.

[0050] The soldering strip is a strip with a thickness of 0.1 to 0.25 mm, so the soldering strip is prone to bending after being stressed along the length direction. The soldering strip bending is prevented by setting a soldering strip discharge trough 251, a soldering strip moving groove 231 and a soldering strip positioning groove 211. In order to further ensure continuous and reliable feeding, a first feeding rod 215 is provided at one end of the soldering strip positioning seat 21, and a first feeding groove 216 is provided on the first feeding rod 215.

Similarly, the third feeding trough 237 and the fourth feeding trough 253 avoid the formation of a cross section between the welding strip moving seat 23 and the welding strip discharge seat 25, thereby avoiding the welding strip from bending at the cross section.
