[0026] Specifically, pulling the handle 3 drives the sliding cover 2 to rotate, and then the sliding cover 2 drives the limit block 7 to rotate, and the connecting column 8 drives the transmission rod 6 to rotate. At this time, the first ring 5 rotates under the drive of the transmission rod 6, and then the guide rail 11 slides with the rotation of the sliding cover 2. At the same time, the rotating block 10 rotates under the drive of the guide rail 11, and finally the sliding cover 2 is opened to the top of the housing 1, so that the operator can conveniently open or close the circuit breaker when needed, thereby preventing the electrical components inside the circuit breaker from being affected by the external environment.

[0027] Reference Figure 2 The fixing assembly includes a heat sink 22, the outer wall of the heat sink 22 is arranged inside the housing 1, and the rear outer wall of the heat sink 22 is fixedly connected to a fixing plate 13;

[0028] Specifically, the heat sink 22 discharges the heat generated by the circuit breaker during operation through its own holes, thereby ensuring that the temperature of the circuit breaker is normal during operation.

[0029] Reference Figure 2 and Figure 4 The outer wall of the rear side of the housing 1 is fixedly connected with a positioning plate 12, and a limiting column 14 is arranged inside the positioning plate 12; the upper and lower outer walls of the limiting column 14 are fixedly connected with a second ring 15, and the second ring 15 is fixedly connected with a connecting rod 16 inside; the right outer wall of the connecting rod 16 is fixedly connected with a third ring 17, and the third ring 17 is fixedly connected with a first rotating shaft 18 inside; the outer wall of the first rotating shaft 18 is fixedly connected with a transmission block 21, and the outer wall of the transmission block 21 is arranged on the right outer wall of the fixed plate 13; the outer wall of the positioning block 19 is fixedly connected to the left outer wall of the fixed plate 13, and the interior of the positioning block 19 is rotatably connected with a second rotating column 20; the outer wall of the second rotating column 20 is rotatably connected to the left inner part of the transmission block 21;

At this time, the first ring 5 rotates around the first rotating column 4 driven by the transmission rod 6, and then the guide rail 11 slides inside the rotating block 10 as the slide cover 2 rotates. At the same time, the rotating block 10 rotates around the second rotating shaft 23 driven by the guide rail 11. Finally, the slide cover 2 closes the housing 1, so that the operator can conveniently open or close the circuit breaker when needed.

When the heat sink 22 needs to be replaced or cleaned, the transmission block 21 is moved to rotate around the second rotating column 20, and then the transmission block 21 drives the first rotating shaft 18 to rotate around the limiting column 14. Then, the connecting rod 16 rotates around the second ring 15 driven by the third ring 17. At the same time, the second ring 15 rotates synchronously with the rotation of the connecting rod 16. Finally, the limiting column 14 falls off from the positioning plate 12, so that the maintenance personnel can quickly remove the heat sink 22 for cleaning, inspection or replacement.
