[0021] Specifically, in order to meet different thickness of the wire 9, the guide sleeve 1 with different caliber of the conical port 1-1 can be placed on the support 8, or different caliber of the guide sleeve 1 can be placed at the same time, when the stripped end of the wire 9 is tinned, first, the suction port 3-8 is connected to the suction device, the tinned end of the wire 9 is inserted vertically downward from the top opening of the guide cylinder 1, the wire 9 passes through the inside of the bottom sleeve 2 and enters the tin liquid 6, the wire 9 is taken out from above the guide sleeve 1, when the tinned end of the wire 9 enters the suction sleeve 3, the airflow can blow off the excess tin liquid on the wire 9, continue to take the wire 9 upward, when the tinned end of the wire 9 passes through the conical port 1-1 of the guide sleeve 1, the outer diameter of the tinned end of the wire 9 is rounded by the conical port 1-1, and the tinning process of the stripped end of the wire 9 is completed.
