Referring to fig. 2-3, a first hole 6 and a second hole 7 are respectively formed in the first adsorption plate 302 and the second adsorption plate 303, a connection hole 5 is formed in the shell cap 301, the piston 304 is slidably connected to the first hole 6 and the second hole 7 through the connection hole 5, a bar-shaped block 305 is movably clamped in the connection hole 5, and when the pressure inside the shell cap 301 is gradually increased, the piston 304 is gradually moved in the direction away from the capacitor 1 body under the action of the pressure, so that the capacitor 1 is made.

Referring to fig. 4-5, the upper surface of the bottom plate 2 is provided with a connecting groove 9, the side surface of the bottom plate 2 is fixedly provided with a fixing block 10, the inside of the fixing plate 4 is provided with a through hole 8, the inside of the fixing block 10 is slidably connected with a pull rod 11, the outer surface of the pull rod 11 is movably sleeved with a spring 12, and one end of the pull rod 11 is movably inserted into the inner side wall of the connecting groove 9 through the through hole 8.

The working principle is as follows: before the capacitor 1 device is used, firstly, the bottom plate 2 is fixedly sleeved on the outer surface of the capacitor 1, then the shell cap 301 is sleeved at the top end of the capacitor 1 body, and at the moment, two groups of fixing plates 4 fixedly installed on the lower surface of the shell cap 301 are movably inserted into the connecting grooves 9 formed in the bottom plate 2, so that the shell cap 301 is installed at the top end of the capacitor 1 body through the fixing plates 4.

Further, pulling bottom plate 2 one side installation's fixed block 10 internally mounted's pull rod 11, make the top of pull rod 11 and the inside wall phase separation of spread groove 9, spring 12 is in compression state this moment, when fixed plate 4 joint is in the inside of spread groove 9, the inside through-hole 8 of seting up of fixed plate 4 is relative with pull rod 11, release pull rod 11 this moment, make pull rod 11 peg graft at the inside wall of spread groove 9 through the inside through-hole 8 of fixed plate 4 under spring 12's spring action, make shell cap 301 fixed mounting in the upper end of condenser 1 body.
