The inside of the rounded corner frame 1 The six regions are all provided with capacitor bodies 4, each capacitor body 4 is separated by a partition 3, a plurality of short round rods 5 are connected to the front and rear sides of the rounded cover 2, a limiting frame 7 is connected to the front and rear sides of the rounded frame 1, a movable plate 6 is slidably connected to the limiting frame 7, the movable plate 6 is provided with a notch, the short round rods 5 fit into the notch of the movable plate 6, the movable plate 6 can clamp the short round rods 5, so that the rounded cover 2 is fixed, a first return spring 8 is sleeved on the limit frame 7, the two ends of the first return spring 8 are respectively connected to the limit frame 7 and the movable plate 6, the first return spring 8 can prevent the movable plate 6 from being easily The rounded cover 2 is easy to dislocate, so that the movable plate 6 clamps the short round rod 5. The bottom of the rounded cover 2 is connected with three round hole columns 14, and the top of the rounded cover 2 is connected with three hollow columns 15. The hollow column 15 is located directly above the round hole column 14. A large circular plate 19 is placed on the hollow column 15. The large circular plate 19 is used to seal the hollow column 15. The large circular plate 19 is provided with sliding grooves on both sides of the front and back of the large circular plate 19. The front and back sides of the top of the hollow column 15 are slidably connected with round head columns 20. The round head columns 20 fit in the sliding grooves of the large circular plate 19. The round head columns 20 are used to clamp the large circular plate 19. The round head design of the round head columns 20 can facilitate the large circular plate 19 squeezes and moves the round head column 20, and a third return spring 21 is provided on both sides of the front and rear of the top of the hollow column 15.

[0024] A plurality of capacitor bodies 4 can be placed in the rounded corner frame 1, and the partition 3 can separate the capacitor bodies 4 to prevent the capacitor bodies 4 from interfering with each other. When the rounded corner cover 2 needs to be covered, the movable plate 6 is pulled, and the first reset spring 8 is compressed. At this time, the rounded corner cover 2 is placed on the rounded corner frame 1, and then the movable plate 6 is released, and the first reset spring 8 is reset from the compressed state, thereby pushing the movable plate 6 to reset.

At this time, the gas can be discharged from the gap between the large circular plate 19 and the hollow column 15. When the air pressure decreases, the second return spring 18 is reset from the stretched state, thereby driving the large circular plate 19 to move downward and reset, and re-seal the rounded frame 1.

[0026] In order to fix the capacitor body 4 in the rounded frame 1, after placing the capacitor, rotate the notch plate 10 to drive the first pulley assembly 11 to rotate, thereby rotating the rear rotating plate 9. When the rear rotating plate 9 rotates, it can drive the second pulley assembly 12 to rotate, thereby rotating the front rotating plate 9. After adjusting to a suitable angle, the notch plate 10 can be stopped from rotating.
