Super capacitor power supply

The utility model relates to the technical field of capacitor power supplies, and discloses a super capacitor power supply, which comprises a power supply box, an inner cavity of the power supply box is provided with a mounting box, two sides of the upper surface of the power supply box are provided with mounting plates, and the middle position between the mounting plates is uniformly provided with first fixing plates. First threaded rods are connected to the upper surfaces of the first fixing plates in a screwed mode, first limiting plates are installed at the bottom ends of the first threaded rods through bearings, and limiting rods are evenly installed at the bottoms of the first limiting plates. The capacitor located in the middle can be limited through downward movement of the first limiting plate, when the damaged capacitor needs to be replaced, the first limiting plate or the second limiting plate at the corresponding position can be separated from the capacitor only by rotating the first threaded rod
