[0042] As Figures 7-8As shown, the moving assembly 16 comprises a fixed seat 161, a moving seat 162 and a driving cylinder 163. The fixed seat 161 is connected with the three-dimensional moving module 13 on one side, and a first track 1611 is arranged on the other side of the fixed seat 161. The moving seat 162 is in sliding connection with the first track 1611.

When the cold riveting head 173 is pressed against the riveting part by the three-dimensional moving module 13, the end of the hot air gun 3 is higher than the end of the cold riveting head 173 due to the movement of the moving seat 162 driven by the driving cylinder 163. Therefore, when the cold riveting head 173 presses the riveting part, the end of the hot air gun 3 is away from the PCB, thereby reducing the influence of the end of the hot air gun 3 on the components on the PCB when the end of the hot air gun 3 is cooled.
