[0029] Working principle: when a capacitor pin soldering device is used, in the initial state, first, two groups of rotating arms 1 are fixed on the upper surface of the base 101, and the rotating shaft 103 set at the top of the rotating arm 1 is connected to the tension knob 104 set at the top of the rotating arm 1, and the inner end of the rotating shaft 103 is connected with a clamping block 105, so as to control the rotation of the fixing mechanism 2 and the clamping mechanism 3 to weld the capacitor on the circuit board, and two groups of supporting plates 206 and threaded shafts 208 are slidably connected to the inner side of the fixed frame 201 clamped and fixed between the two clamping blocks 105, so as to fix circuit boards of different sizes, and a movable groove 304 is opened on the back plate 301 set at the bottom of the fixed frame 201, and the top plate 306, the top rod 307 and the clamping plate 308 slidably connected to the movable groove 304 are supported by the spring 305, so as to clamp the circuit board and the capacitor on the circuit board;
