Electric double-layer power capacitor

The utility model relates to the technical field of capacitors, in particular to a double-electric-layer power capacitor which comprises a base plate, a guide rod, a sliding sleeve, a reset spring, amovable rod, a movable clamp, a fixed clamp, a pull rod, a circuit board, a machine body foundation, a permanent magnet, a connecting rod and a metal iron sheet. The guide rod is fixedly installed onthe base plate and located in the middle of the interior of the installation groove, the outer surface of the guide rod is sleeved with the sliding sleeve, the sliding sleeve is connected with the guide rod in a sliding mode, and the outer surface of the guide rod is sleeved with the reset spring. According to the utility model, the purpose of enabling the double-electric-layer capacitor to have rapid mounting, fixing and dismounting capabilities on the circuit board is achieved, the previous mode of bonding and fixing by using hot melt adhesive is replaced, the stability of the double-electric-layer capacitor can be i
