In the initial state, there is a gap between the first soft pad 13, the second soft pad 14 and the storage plate 1. By pushing the two moving parts, the two pressure blocks 12 are respectively located directly above the edges of the long sides of the PCB board. At this time, the inverted T-shaped slider 11 and the inverted T-shaped slide column 5 move with the moving parts, and then the paddle 7 is driven to drive the two pressure plates 3 to move inward through the inverted T-shaped slide column 5, so that the two pressure plates 3 are respectively located directly above the edges of the short sides of the PCB board. When the moving part and the pressure plate 3 are adjusted, the electric push rod 19 is started, and the push rod of the electric push rod 19 drives the moving part to move downward through the support plate and the inverted T-shaped slider 11, so that the moving part drives the pressure plate 3 to move downward through the inverted T-shaped slide column 5 and the fixed plate 6, and at the same time drives the pressure block 12 on the moving part to move downward. When the second soft pad 14 at the bottom of the pressure block 12 and the first soft pad 13 at the bottom of the pressure plate 3 fix the PCB board, the electric push rod 19 stops operating, thereby achieving the fixation of the PCB board. If it is necessary to adjust the welding angle of the PCB board, the storage plate 1 can be rotated by the support column 18. When the angle is determined, the clamping column 27 can be clamped in a positioning hole 25 on the rotating plate 24 and the positioning groove 26 of the base 22 to achieve the locking of the support column 18 and the storage plate 1.
