Two locking posts are provided on its bottom surface, which are fixed into the positioning holes 2. Several screw holes are evenly spaced on its upper surface, and circuit board clamping bolts 10 are installed in the screw holes. The sponge pad 9 is installed on the side of the circuit board locking block 8 without holes. Two slide rails 11 are installed parallel to each other in the center of the upper surface of the base plate 1, and each slide rail 11 is equipped with two sliders 12. Slider fixing screws 13 are installed on the side of the sliders 12. The slider connecting frame 14 is bridge-shaped, with both ends installed on the upper surfaces of the sliders 12 on the two slide rails 11. A positioning screw seat 15 is installed in the center of the outward-facing side of the slider connecting frame 14. The rotating clamping plate 16 is U-shaped, with a screw fixedly installed in the center of its bottom. The screw passes through the slider connecting frame 14 and the positioning screw seat 15 and is then locked in place with a fastening nut 17. Several screw holes are opened on the upper side of the rotating clamping plate 16, and clamping plate screws 18 are installed in the screw holes. The constant-temperature soldering station 3 has a touch screen on its front side, which can control the start and stop of the pointed soldering iron 5, the knife-shaped soldering iron 6, and the hot air blower 7, and display their real-time operating temperature.
