The telescopic guide rod 22 is fixedly connected to the bottom surface of the screening box 11. A motor 23 is fixedly connected to the bottom surface of the mounting plate 21. Through the driving force of the drive shaft 12 and vibration, the output end of the motor 23 passes through the screening box 11 and extends to the outside. A screening frame 24 is fixedly connected to the upper surface of the mounting plate 21. A screening frame 25 is slidably connected to the screening frame 24 to perform screening operations on the capacitor. The screening frame 25 is fixed to the screening frame 24 by a pin 26.

[0032] A door 111 is rotatably connected to one side of the screening box 11, and a handle 112 is fixedly connected to one side of the door 111 for easy opening of the screening box 11 and removal of the screened capacitors.
