Two groups of positioning columns 24 are symmetrically fixedly installed at the bottom of the top cover 5, and the number of the two groups of positioning columns 24 is three. The six positioning columns 24 are respectively movably installed inside the six positioning holes 23. Fixed seats 7 are fixedly installed at both ends of the top of the top cover 5, and fixing holes 8 are symmetrically opened at the top of the fixed seats 7. Adjusting and fixing assemblies 9 are fixedly installed on both sides of the protection frame 1, and the top of the adjusting and fixing assemblies 9 is connected to the fixed seats 7;

[0021] The adjusting and fixing component 9 includes a support base 10, and the support base 10 is fixedly installed at the outer bottom end of the protective frame 1. A sleeve 11 is fixedly installed at the top of the support base 10, and an annular plate 12 is fixedly installed at the top of the sleeve 11. A circular movable block 13 is slidably installed inside the sleeve 11. Four positioning sliders 21 are evenly and fixedly installed on the outer side of the circular movable block 13. Four positioning chutes 22 are evenly penetrated through the inner wall of the sleeve 11, and the four positioning sliders 21 are respectively slidably penetrated and installed inside the four positioning chutes 22. A positioning bearing 14 is fixedly penetrated and installed inside the circular movable block 13. A movable rod 15 is rotatably installed inside the positioning bearing 14, and the bottom of the movable rod 15 extends to the bottom of the circular movable block 13. The top of the movable rod 15 penetrates through the annular plate 12 and extends above the sleeve 11. A positioning spring 16 is fixedly installed between the circular movable block 13 and the annular plate 12, and the positioning spring 16 is sleeved on the outer side of the movable rod 15. A connecting sleeve 17 is fixedly installed above the annular plate 12 and on the outer side of the movable rod 15. A handle 18 is fixedly installed on the outer side of the connecting sleeve 17. A movable frame 19 is fixedly installed at the top of the movable rod 15. Two fixing rods 20 are symmetrically and fixedly installed at the bottom end of the movable frame 19 away from the movable rod 15, and the bottom of the fixing rods 20 extends into the fixing holes 8.

[0022] During use, through the interaction of the protective frame 1, the capacitor body 2, the top cover 5, the fixed seat 7, the fixed holes 8 and the adjusting and fixing component 9, the composite capacitor can be better protected during use, avoiding damage caused by pressure, improving its service life, and thus facilitating better practicality. And through the interaction of the positioning sliders 21 and the positioning chutes 22, when the circular movable block 13 moves, better stability can be achieved, thus ensuring that the adjusting and fixing component 9 can move stably.

[0023] Working principle: During operation, first pull the handle 18 upward, driving the connecting sleeve 17 to move upward. The connecting sleeve 17 drives the movable rod 15 to move upward. Under the action of the positioning bearing 14, the movable rod 15 drives the circular movable block 13 to move upward. The circular movable block 13 drives the positioning slider 21 to slide inside the positioning chute 22, which can ensure better stability when the circular movable block 13 moves. At the same time, the upward movement of the circular movable block 13 squeezes the positioning spring 16, causing the positioning spring 16 to undergo elastic deformation. At the same time, the movable rod 15 drives the movable frame 19 to move upward, and the movable frame 19 drives the fixed rod 20 to move upward. The upward movement of the fixed rod 20 disengages from the fixing hole 8, releasing the fixation of the fixed seat 7. Then, drive the connecting sleeve 17 to rotate through the handle 18. The connecting sleeve 17 drives the movable rod 15 to rotate, the movable rod 15 drives the movable frame 19 to rotate, and the movable frame 19 drives the fixed rod 20 to move. After the movable frame 19 rotates 180 degrees, the movable frame 19 and the fixed rod 20 remove the occlusion of the top of the top cover 5. Then release the handle 18, and then the top cover 5 can be removed from the top of the protection frame 1. After the top cover 5 is removed, place the capacitor body 2 inside the protection frame 1, and then place the top cover 5 on the top of the protection frame 1 again, and make the positioning post 24 at the bottom of the top cover 5 insert into the positioning hole 23 at the top of the protection frame 1. Then pull the handle 18 upward again, causing the movable frame 19 to move upward. The movable frame 19 drives the fixed rod 20 to move upward. After the fixed rod 20 moves above the fixed seat 7, drive the connecting sleeve 17 to rotate in the reverse direction through the handle 18, so that the fixed rod 20 moves back above the fixing hole 8. Then slowly release the handle 18. Under the action of gravity and the rebounding force of the positioning spring 16, the circular movable block 13 is pushed downward. The circular movable block 13 drives the movable rod 15 to move downward through the positioning bearing 14. The movable rod 15 drives the movable frame 19 to move downward, and the movable frame 19 drives the fixed rod 20 to move downward into the fixing hole 8, fixing the fixed seat 7 again, so that the top cover 5 is fixed on the top of the protection frame 1. Then during use, a protection is formed outside the capacitor body 2 through the protection frame 1 and the top cover 5. At the same time, under the action of the strip-shaped heat dissipation openings 4, while protecting the capacitor body 2, it will not affect its heat dissipation. In this way, during the use of the composite capacitor, it is convenient to obtain better protection, avoid being damaged by pressure, improve its service life, and thus facilitate achieving better practicality.
