After the operator places the condenser between the two flexible clamps 87, the cylinder 84 is started, which can drive the connectors 83 and the synchronization rods 85 at both ends to move toward the center at the same time, thereby driving the sliding seat 86 to slide on the slide rail 1 81, thereby realizing the clamping and fixing of the condenser by using the flexible clamp 87.

[0047] In this embodiment, a hole-expanding assembly and a wire-winding mechanism (the hole-expanding assembly and the wire-winding mechanism are not shown in the figure) can also be provided above the rotating platform 5. The hole-expanding assembly can be used to expand the inner diameter of the condenser tube, so that one condenser tube can be inserted into the interior of another expanded condenser tube to achieve better welding between the two.

Generally, in current technology, the hole-expanding assembly and the wire-winding mechanism both have finished product structures, so the functions and structures of the hole-expanding assembly and the wire-winding mechanism will not be elaborated on in detail.
