It is worth mentioning that the adjusting part 22 is configured to allow the pivot end 221 of the adjusting part 22 to rotate around a fixed rotating shaft 23 relative to the housing 10, so that the swing track of the conducting end 222 of the adjusting part 22 is controllable. For example, in a specific example of the circuit breaker 200 of the present invention, a middle portion of the fixed rotating shaft 23 is disposed at the pivot end 221 of the adjusting portion 22, and both end portions of the fixed rotating shaft 23 are rotatably mounted to the second housing 12 and the carrying case 13, respectively, so that when the pivot end 221 of the adjusting portion 22 is driven, the pivot end 221 of the adjusting portion 22 can rotate around the fixed rotating shaft 23 relative to the housing 10, thereby controlling a swing track of the conducting end 222 of the adjusting portion 22.

In a specific example of the circuit breaker 200 of the present invention, the cross-section of at least one section of the pivot shaft 33 is non-circular, such as triangular, quadrilateral, oval, etc., and accordingly, the shape and size of the holding hole 313 of the handle 31 are the same as the shape and size of the section of the pivot shaft 33, so that when the section of the pivot shaft 33 is installed in the holding hole 313 of the handle 31, the pivot shaft 33 and the handle 31 are prevented from relative rotation, so that the fourth gear 44 can drive the installation end 311 of the handle 31 to rotate relative to the housing 10 through the pivot shaft 33. Preferably, the pivot shaft 33 is a cylinder with a triangular cross-section.

Further, the first gear 41 has a first large wheel 411 and a first small wheel 412 held at a side of the first large wheel 411, and the first large wheel 411 and the first small wheel 412 of the first gear 41 are all gears, wherein the first gear 41 is rotatably mounted to the first accommodation space 14 of the housing 10 in such a manner that the first large wheel 411 faces the bearing case 13 and the first small wheel 412 faces the first housing 11, and the first large wheel 411 of the first gear 41 is engaged with the rotor of the driving motor 45. The second gear 42 has a second large wheel 421 and a second small wheel 422 held at a side of the second large wheel 421, and the second large wheel 421 and the second small wheel 422 of the second gear 42 are all gears, wherein the second gear 42 is rotatably mounted to the second receiving space 15 of the housing 10 in such a manner that the second large wheel 421 faces the first housing 11 and the second small wheel 422 faces the carrying case 13, and the second large wheel 421 of the second gear 42 is engaged with the first small wheel 412 of the first gear 41.

For example, the third large wheel 431 of the third gear 43 being a full gear means that the third large wheel 431 is provided with gear teeth on the periphery, the third small wheel 432 of the third gear 43 being a half gear means that one half of the periphery of the third small wheel 432 is provided with gear teeth, and the fourth gear 44 being a partial gear means that one quarter of the periphery of the fourth gear 44 is provided with gear teeth.

It is understood that when the teeth of the fourth gear 44 are engaged with the teeth of the third small wheel 432 of the third gear 43, the third gear 43 can drive the fourth gear 44 to synchronously rotate relative to the housing 10 after the third gear 43 is driven to rotate relative to the housing 10. Accordingly, if the teeth of the fourth gear 44 are not engaged with the teeth of the third small wheel 432 of the third gear 43, even if the third gear 43 is driven to rotate relative to the housing 10, the third gear 43 cannot drive the fourth gear 44 to rotate, and the rotation of the fourth gear 44 does not affect the third gear 43. In other words, if the teeth of the fourth gear 44 are not engaged with the teeth of the third small wheel 432 of the third gear 43, the third gear 43 and the fourth gear 44 are independent from each other.

Fig. 14 shows a positional relationship among the manual switching mechanism 30, the automatic switching mechanism 40, and the measurement mechanism 50 when the electricity control mechanism 20 of the circuit breaker 200 is in the off state. The teeth of the fourth gear 44 face the side of the third small wheel 432 of the third gear 43 where the teeth are not provided, the operating member 433 of the third gear 43 is located at the side of the first end 462 of the toggle lever 46, the first positioner 55 and the second sensor 52 correspond to each other to allow the second sensor 52 to sense the first positioner 55, and the second positioner 56 and the third sensor 53 correspond to each other to allow the third sensor 53 to sense the second positioner 56.

When the rotor of the driving motor 45 rotates to provide a driving force, on one hand, the driving motor 45 drives the first gear 41 to rotate, the first gear 41 drives the second gear 42 to rotate, the second gear 42 drives the third gear 43 to rotate, the third gear 43 makes the operating element 433 contact with the first end 462 of the shift lever 46 during the rotation process to drive the first end 462 of the shift lever 46, at this time, the shift lever 46 further transmits the driving force transmitted by the third gear 43 to the adjusting portion 22 through the driving element 24 to allow the adjusting portion 22 to be released, so that the pivot end 221 of the adjusting portion 22 rotates relative to the housing 10 under the action of the torsion spring of the adjusting portion 22, so as to further drive the mounting end 311 of the handle 31 to rotate relative to the housing 10 and drive the operating end 312 of the handle 31 to swing downward, while the mounting end 311 of the handle 31 rotates to drive the fourth gear 44 to rotate through the pivot shaft 33; on the other hand, the first positioner 55 and the second sensor 52 correspond to each other to allow the second sensor 52 to sense the first positioner 55, and the second positioner 56 and the third sensor 53 correspond to each other to allow the third sensor 53 to sense the second positioner 56.

When the handle 31 is pulled up, the fourth gear 44 is rotated, because the teeth of the fourth gear 44 correspond to the portion of the third small wheel 432 of the third gear 43, on which no teeth are provided, and therefore, the fourth gear 44 is prevented from contacting the third gear 43 when the fourth gear 44 is rotated by the handle 31. In addition, when the handle 31 is pulled up, the handle 31 drives the lever 46 to rotate relative to the housing 10 through the adjusting portion 22 and the driving portion 24.

As shown in fig. 23 to 28, a circuit breaker according to another preferred embodiment of the present invention is disclosed and described in the following description, wherein the circuit breaker includes a housing 10A, an electric control mechanism 20A, a manual switching mechanism 30A and an automatic switching mechanism 40A.

The housing 10A includes a first housing 11A, a second housing 12A and a carrying case 13A, and the housing 10A has a first accommodating space 14A, a second accommodating space 15A, an operation passage 16A, a first wiring passage 17A and a second wiring passage 18A. The carrying case 13A has a first side portion 131A and a second side portion 132A corresponding to the first side portion 131A, wherein the first outer case 11A is mounted to the carrying case 13A, and the first outer case 11A is located at the first side portion 131A of the carrying case 13A to form the first receiving space 14A between the first outer case 11A and the carrying case 13A, and correspondingly, the second outer case 12A is mounted to the carrying case 13A, and the second outer case 12A is located at the second side portion 132A of the carrying case 13A to form the second receiving space 15A between the second outer case 12A and the carrying case 13A. The operation passage 16A, the first wiring passage 17A and the second wiring passage 18A communicate with the second accommodation space 15A, respectively.

The electric control mechanism 20A is mounted in the second accommodating space 15A of the housing 10A, wherein the electric control mechanism 20A has an on state and an off state, and the electric control mechanism 20A is operable to switch between the on state and the off state. The circuit breaker allows one electric wire electrically connected to a power supply to be electrically connected to the electric control mechanism 20A after extending to the second accommodation space 15A through the first wiring passage 17A of the housing 10A, and allows one electric wire electrically connected to a consumer to be electrically connected to the electric control mechanism 20A after extending to the second accommodation space 15A through the second wiring passage 18A of the housing 10A. The circuit breaker allows the current supplied from the power source to be transmitted to the electric device through the electric control mechanism 20A when the electric control mechanism 20A is switched from the off state to the on state, and prevents the current supplied from the power source from being transmitted to the electric device through the electric control mechanism 20A when the electric control mechanism 20A is switched from the on state to the off state. And when the electric control mechanism 20A is in the on state and the circuit is abnormal, the electric control mechanism 20A can be automatically switched from the on state to the off state to prevent the current provided by the power supply from being continuously transmitted to the electric equipment through the electric control mechanism 20A, so that the electric safety can be effectively ensured.

It is noted that the structure and principle of the electric control mechanism 20A of the present invention are consistent with those of the electric control mechanism of the circuit breaker (air switch) of the prior art. Specifically, the electric control mechanism 20A includes a control section 21A and an adjusting section 22A, wherein the control section 21A is mounted in the second accommodating space 15A of the housing 10A, and electric wires electrically connected to a power source are electrically connected to the control section 21A after extending to the second accommodating space 15A via the first wiring passage 17A of the housing 10A, and electric wires electrically connected to a consumer are electrically connected to the control section 21A after extending to the second accommodating space 15A via the second wiring passage 18A of the housing 10A, wherein the adjusting section 22A has a pivot end 221A and a conducting end 222A corresponding to the pivot end 221A, the pivot end 221A of the adjusting section 22A is rotatably mounted in the second accommodating space 15A of the housing 10A, and the conducting end 222A of the adjusting section 22A extends to the control section 21A, when the adjusting portion 22A is driven to rotate the pivot end 221A relative to the housing 10A, the conducting end 222A of the adjusting portion 22A swings relative to the housing 10A to change the relative position relationship between the conducting end 222A of the adjusting portion 22A and the power control portion 21A, so as to switch the state of the power control mechanism 20A.

It is worth mentioning that the adjusting part 22A is configured to allow the pivot end 221A of the adjusting part 22A to rotate around a fixed rotating shaft 23A relative to the housing 10A, so that the swing track of the conducting end 222A of the adjusting part 22A is controllable. For example, in a specific example of the circuit breaker of the present invention, a middle portion of the fixed rotating shaft 23A is disposed at the pivot end 221A of the adjusting portion 22A, and both end portions of the fixed rotating shaft 23A are rotatably mounted to the second housing 12A and the carrying case 13A, respectively, so that when the pivot end 221A of the adjusting portion 22A is driven, the pivot end 221A of the adjusting portion 22A can rotate around the fixed rotating shaft 23A relative to the housing 10A, thereby controlling a swing track of the conducting end 222A of the adjusting portion 22A.

The manual switching mechanism 30A is installed between the second housing 12A and the carrying housing 13A of the housing 10A, and the adjusting portion 22A of the electricity control mechanism 20A is drivingly connected to the manual switching mechanism 30A to allow the electricity control mechanism 20A to be controlled to be switched between the on state and the off state by manually operating the manual switching mechanism 30A.

Specifically, the manual switching mechanism 30A includes a handle 31A and a driving arm 32A. The handle 31A has a mounting end 311A and an operating end 312A corresponding to the mounting end 311A, wherein the mounting end 311A of the handle 31A is rotatably mounted to the second accommodating space 15A of the housing 10A, and the operating end 312A of the handle 31A extends from the second accommodating space 15A of the housing 10A to the outside of the housing 10A through the operating passage 16A of the housing 10A. Both ends of the driving arm 32A extend to be connected to the mounting end 311A of the handle 31A and the pivot end 221A of the adjusting portion 22A, respectively. Preferably, the drive arm 32A is "V" shaped.

Outside the housing 10A, the circuit breaker allows the operating end 312A of the handle 31A to be operated to swing up and down, the up-and-down swing of the handle 31A drives the mounting end 311A of the handle 31A to rotate relative to the housing 10A, and further drives the pivot end 221A of the adjusting portion 22A to rotate relative to the housing 10A through the driving arm 32A, and drives the conducting end 222A of the adjusting portion 22A to swing relative to the housing 10A, so as to switch the state of the power control mechanism 20A.

Further, the manual switching mechanism 30A includes a pivot shaft 33A, wherein two ends of the pivot shaft 33A extend to the second housing 12A and the carrying housing 13A of the housing 10A, respectively, and the mounting end 311A of the handle 31A is disposed on the pivot shaft 33A, so that when the operating end 312A of the handle 31A is driven to swing up and down relative to the housing 10A, the mounting end 311A of the handle 31A can rotate relative to the housing 10A. Preferably, in this preferred example of the circuit breaker of the present invention, a middle portion of the pivot end 33A is fixedly mounted to the mounting end 311A of the handle 31A, and both ends of the pivot shaft 33A are rotatably mounted to the second housing 12A and the carrier housing 13A of the housing 10A, respectively, so that the mounting end 311A of the handle 31A is rotatably mounted to the housing 10A through the pivot shaft 33A. Alternatively, in other examples of the circuit breaker of the present invention, a middle portion of the pivot shaft 33A is rotatably mounted to the mounting end 311A of the handle 31A, and both ends of the pivot shaft 33A are fixedly mounted to the second housing 12A and the carrying case 13A of the housing 10A, respectively.

The automatic switching mechanism 40A is mounted to the housing 10A, and the adjusting portion 22A of the electric control mechanism 20A is drivingly connected to the automatic switching mechanism 40A to allow the automatic switching mechanism 40A to automatically control the electric control mechanism 20A to switch between the on state and the off state.

Specifically, the automatic switching mechanism 40A includes a first gear 41A, a second gear 42A, a third gear 43A, a fourth gear 44A, and a driving motor 45A. The driving motor 45A, the first gear 41A, the second gear 42A, the third gear 43A, and the fourth gear 44A are respectively mounted to the first accommodation space 14A of the housing 10A, wherein the first gear 41A is rotatably mounted to the housing 10A and is drivably connected to the drive motor 45A, wherein the second gear 42A is rotatably mounted to the housing 10A and is drivably connected to the first gear 41A, wherein the third gear 43A is rotatably mounted to the housing 10A and is drivably connected to the second gear 42A, wherein the fourth gear 44A is rotatably mounted to the housing 10A and is drivably connected to the third gear 43A, wherein the mounting end 311A of the handle 31A is drivably connected to the fourth gear 44A. Preferably, the first gear 41A, the second gear 42A, the third gear 43A and the fourth gear 44A are arranged to rotate around a fixed shaft, respectively, so that the relative positions of the first gear 41A, the second gear 42A, the third gear 43A and the fourth gear 44A can be prevented from being changed. When the rotor of the driving motor 45A rotates to provide a driving force, the driving force can be transmitted to the handle 31A through the first gear 41A, the second gear 42A, the third gear 43A and the fourth gear 44A in sequence to drive the mounting end 311A of the handle 31A to rotate relative to the housing 10A.

Preferably, the bearing shell 13A has a rotating shaft through hole 133A penetrating through the first side portion 131A and the second side portion 132A of the bearing shell 13A to communicate the first accommodating space 14A and the second accommodating space 15A of the housing 10A, wherein the rotating shaft 33A is mounted on the fourth gear 44A after extending from the second accommodating space 15A of the housing 10A to the first accommodating space 14A through the rotating shaft through hole 133A of the bearing shell 13A, so that when the fourth gear 44A is driven to rotate relative to the housing 10A, the fourth gear 44A drives the mounting end 311A of the handle 31A to rotate relative to the housing 10A through the rotating shaft 33A. It can be understood that when the fourth gear 44A drives the mounting end 311A of the handle 31A to rotate relative to the housing 10A through the pivot shaft 33A, the operating end 312A of the handle 31A is driven to swing up and down relative to the housing 10A.

Preferably, when the fourth gear 44A is injection molded, one end of the pivot shaft 33A is wrapped inside the fourth gear 44A such that a free end of the pivot shaft 33A extends from one side of the fourth gear 44A in a direction away from the fourth gear 44A, wherein the handle 31A has a retaining hole 313A formed at the mounting end 311A of the handle 31A, and the retaining hole 313A of the handle 31A corresponds to the rotation shaft through hole 133A of the carrying case 13A to allow the free end of the pivot shaft 33A to extend to the retaining hole 313A of the handle 31A after passing through the rotation shaft through hole 133A of the carrying case 13A. More preferably, the holding hole 313A of the handle 31A is a through hole such that the free end of the pivot shaft 33A extends to and is rotatably mounted to the second housing 12A of the housing 10A after passing through the holding hole 313A of the handle 31A.

In a specific example of the circuit breaker of the present invention, the cross-section of at least one section of the pivot shaft 33A is non-circular, such as triangular, quadrilateral, oval, etc., and accordingly, the shape and size of the holding hole 313A of the handle 31A are consistent with the shape and size of the section of the pivot shaft 33A, so that the section of the pivot shaft 33A is installed in the holding hole 313A of the handle 31A, the pivot shaft 33A and the handle 31A are prevented from relative rotation, so that the fourth gear 44A can drive the mounting end 311A of the handle 31A to rotate relative to the housing 10A through the pivot shaft 33A. Preferably, the pivot shaft 33A is a cylinder having a triangular sectional shape.

Further, the first gear 41A has a first large wheel 411A and a first small wheel 412A held at a side of the first large wheel 411A, and the first large wheel 411A and the first small wheel 412A of the first gear 41A are each an all-gear, wherein the first gear 41A is rotatably mounted to the first accommodation space 14A of the housing 10A with the first large wheel 411A facing the bearing case 13A and the first small wheel 412A facing the first housing 11A, and the first large wheel 411A of the first gear 41A is engaged with the rotor of the drive motor 45A. The second gear 42A has a second large wheel 421A and a second small wheel 422A held at the side of the second large wheel 421A, and the second large wheel 421A and the second small wheel 422A of the second gear 42A are both full gears, wherein the second gear 42A is rotatably mounted to the second accommodation space 15A of the housing 10A in such a manner that the second large wheel 421A faces the first outer case 11A and the second small wheel 422A faces the carrying case 13A, and the second large wheel 421A of the second gear 42A engages with the first small wheel 412A of the first gear 41A. The third gear 43A has a third large wheel 431A and a third small wheel 432A held at a side of the third large wheel 431A, and the third large wheel 431A is a full gear, and the third small wheel 432A is a half gear, wherein the third gear 43A is rotatably mounted to the first accommodation space 14A of the housing 10A in such a manner that the third large wheel 431A faces the carrying case 13A and the third small wheel 432A faces the first housing 11A, and the third large wheel 431A of the third gear 43A is engaged with the second small wheel 422A of the second gear 42A. The fourth gear 44A is a partial gear, i.e. only a small part of the teeth of the circumference of the fourth gear 44A, and the fourth gear 44A can engage with the third small wheel 432A of the third gear 43A.

It is worth mentioning that the full gear that the circuit breaker defined all is provided with the teeth of a cogwheel at the periphery of a gear, and half gear is that the peripheral half of a gear is provided with the teeth of a cogwheel, and local gear is that the peripheral quarter of a gear is provided with the teeth of a cogwheel. For example, the third large wheel 431A of the third gear 43A is a full gear, which means that the periphery of the third large wheel 431A is provided with gear teeth, the third small wheel 432A of the third gear 43A is a half gear, which means that the periphery of the third small wheel 432A is partially provided with gear teeth, a gear end 441A of the fourth gear 44A is a partial gear, the gear end 441A is a quarter of the periphery of the fourth gear 44A is provided with gear teeth, and the gear end 441A is used for being meshed with the third small wheel 432A.

It is understood that when the teeth of the fourth gear 44A are engaged with the teeth of the third small wheel 432A of the third gear 43A, the third gear 43A can drive the fourth gear 44A to synchronously rotate relative to the housing 10A after the third gear 43A is driven to rotate relative to the housing 10A. Accordingly, if the teeth of the fourth gear 44A are not engaged with the teeth of the third small wheel 432A of the third gear 43A, even if the third gear 43A is driven to rotate relative to the housing 10A, the third gear 43A cannot drive the fourth gear 44A to rotate, and the rotation of the fourth gear 44A does not affect the third gear 43A. In other words, the third gear 43A and the fourth gear 44A are independent from each other if the teeth of the fourth gear 44A are not engaged with the teeth of the third small wheel 432A of the third gear 43A.

Further, the bearing housing 13A has a sliding groove 134A penetrating the first side 131A and the second side 132A of the bearing housing 13A to communicate the first accommodating space 14A and the second accommodating space 15A. The automatic switching mechanism 40A further includes a lever 46A, wherein the lever 46A has a lever middle portion 461A and a first end portion 462A and a second end portion 463A extending from the lever middle portion 461A to opposite sides, respectively, wherein the lever middle portion 461A of the lever 46A is rotatably mounted to the carrier case 13A of the housing 10A, wherein the first end portion 462A of the lever 46A extends to an upper portion of the third small wheel 432A of the third gear 43A and can be driven by the third small wheel 432A, wherein the second end portion 463A of the lever 46A extends from the first accommodating space 14A of the housing 10A to the second accommodating space 15A via the sliding groove 134A of the carrier case 13A and is drivably connected to the adjusting portion 22A such that the adjusting portion 22A can drive the lever 46A through the second end portion 463A of the lever 46A A makes a rotation relative to the carrying case 13A of the housing 10A. Preferably, the shift lever middle portion 461A of the shift lever 46A is rotatably mounted to the bearing shell 13A by a fixed shaft, such that the swing locus of the first end 462A and the second end 463A of the shift lever 46A is controllable.

The electric control mechanism 20A further includes a driving member 24A, wherein the driving member 24A is held in the second receiving space 15A of the housing 10A and is drivably connected to the adjusting portion 22A, and the driving member 24A has a mounting groove 241A, the mounting groove 241A of the driving member 24A corresponds to the sliding groove 134A of the carrying case 13A to allow the second end 463A of the shift lever 46A to be mounted to the mounting groove 241A of the driving member 24A after passing through the sliding groove 134A of the carrying case 13A, such that the adjusting portion 22A drives the second end 463A of the shift lever 46A through the driving member 24A to rotate the shift lever 46A relative to the housing 10A.

After the lever middle portion 461A of the lever 46A is rotatably mounted to the carrying case 13A, there is a distance between the first end 462A of the lever 46A and the surface of the carrying case 13A, and the distance is greater than the sum of the thickness dimensions of the third large wheel 431A and the third small wheel 432A of the third gear 43A, so as to avoid the contact between the first end 462A of the lever 46A and the third small wheel 432A of the third gear 43A. Preferably, the third gear 43A has an operating member 433A, wherein the operating member 433A protrudes from the third small wheel 432A, and the operating member 433A can contact with the first end 462A of the shift lever 46A to drive the first end 462A of the shift lever 46A. Preferably, the operating member 433A of the third gear 43A and one of the gear teeth of the third small wheel 432A are of an integral structure.

It should be noted that the operating element 433A has a stopping end 4331A, the stopping end 4331A extends to any one of the teeth of the third small wheel 432A, and when the third small wheel 432A rotates in the housing 10A, the first end 462A just acts on the stopping end 4331A, so the shift lever 46A cannot further drive the adjusting portion 22A, and the conducting end 222A of the adjusting portion 22A cannot change relative to the position of the control portion 21A, and therefore the state of the control mechanism 20A cannot be switched.

The circuit breaker further includes a measuring mechanism 50A, wherein the measuring mechanism 50A includes a first sensor 51A, a second sensor 52A, a third sensor 53A, a fourth sensor 54A, a first locator 55A, a second locator 56A, and a circuit board 57A. The first sensor 51A and the second sensor 52A are attached to the circuit board 57A adjacent to each other, the third sensor 53A and the fourth sensor 54A are attached to the circuit board 57A adjacent to each other, the first positioner 55A is provided on the second large wheel 421A of the second gear 42A and faces the first housing 11A, and the second positioner 56A is provided on the fourth gear 44A and faces the first housing 11A. The circuit board 57A is mounted to the first receiving space 14A of the housing 10A, and the surface of the carrying case 13A defining the first receiving space 14A is located on one side of the circuit board 57A, and the main body portions of the second gear 42A, the third gear 43A, the fourth gear 44A and the lever 46A are all located on the other side of the circuit board 57A, wherein the first sensor 51A and the second sensor 52A are hidden under the second large wheel 421A of the second gear 42A in such a manner as to face the second large wheel 421A of the second gear 42A, so that the first sensor 51A and the second sensor 52A can sense the first positioner 55A corresponding to the first positioner 55A, respectively, and accordingly, the third sensor 53A and the fourth sensor 54A are hidden under the fourth positioner 55A in such a manner as to face the fourth gear 44A A lower portion of the gear 44A so that the third sensor 53A and the fourth sensor 54A can sense the second positioner 56A corresponding to the second positioner 56A, respectively. Preferably, the first sensor 51A, the second sensor 52A, the third sensor 53A and the fourth sensor 54A may be photoelectric sensors, and the first positioner 55A and the second positioner 56A may be metal blocks, so that the first sensor 51A and the second sensor 52A can measure the rotation angle of the second gear 42A by sensing the position of the first positioner 55A, and the third sensor 53A and the fourth sensor 54A can measure the rotation angle of the fourth gear 44A by sensing the position of the second positioner 56A.

The measuring mechanism 50A further includes a processor 58A, wherein the processor 58A is attached to the circuit board 57A such that the first sensor 51A, the second sensor 52A, the third sensor 53A, and the fourth sensor 54A are connected to the processor 58A through the circuit of the circuit board 57A, so that the processor 58A can receive sensing signals from the first sensor 51A, the second sensor 52A, the third sensor 53A, and the fourth sensor 54A. The driving motor 45A of the automatic switching mechanism 40A is controllably connected to the processor 58A to control the operating state of the driving motor 45A by the processor 58A. For example, the processor 58A can control the rotation amplitude and the rotation direction of the drive motor 45A, and thus can control the rotation angles and the rotation directions of the first gear 41A, the second gear 42A, the third gear 43A, and the fourth gear 44A.

Fig. 23 shows a positional relationship among the manual switching mechanism 30A, the automatic switching mechanism 40A, and the measurement mechanism 50A when the electric control mechanism 20A of the circuit breaker is in the off state. The gear end 441A of the fourth gear 44A faces a side of the third small wheel 432A of the third gear 43A where no gear teeth are provided, the operating member 433A of the third gear 43A is located at a side of the first end 462A of the shift lever 46A, the first positioner 55A and the first sensor 51A correspond to each other to allow the first sensor 51A to sense the first positioner 55A, and the second positioner 56A and the third sensor 53A correspond to each other to allow the third sensor 53A to sense the second positioner 56A.

Fig. 24 shows a process in which the circuit breaker controls the electric control mechanism 20A to switch from the off state to the on state in an automatic mode, and fig. 25 shows a positional relationship of the manual switching mechanism 30A, the automatic switching mechanism 40A, and the measuring mechanism 50A when the circuit breaker is in the on state. When the rotor of the driving motor 45A rotates to provide the driving force, on the one hand, the driving motor 45A drives the first gear 41A to rotate, the first gear 41A drives the second gear 42A to rotate, the second gear 42A drives the third gear 43A to rotate, and the third gear 43A drives the fourth gear 44A to rotate.

It should be noted that in the present embodiment, the second gear 42A drives the third gear 43A to rotate, and the number of rotations of the second gear 43A in the housing 10A is two. Due to the gear arrangement of the second gear 42A, the third gear 43A and the fourth gear 44A, only after the second gear 42A completes the two-turn rotation process of the housing 10A, the fourth gear 44A drives the mounting end 311A of the handle 31A to rotate through the pivot shaft 33A to drive the operating end 312A of the handle 31A to swing upwards, at this time, the handle 31A drives the pivot end 221A of the adjusting portion 22A to rotate relative to the housing 10A through the driving arm 32A, and drives the conducting end 22A of the adjusting portion 22A to swing relative to the housing 10A to switch the state of the electric control mechanism 20A from the off state to the on state; on the other hand, the adjusting part 22A of the electric control mechanism 20A drives the shift lever 46A to synchronously rotate through the driving part 24A, so as to change the relative positional relationship between the first end 462A of the shift lever 46A and the third gear 43A; in yet another aspect, the first locator 55A and the first sensor 51A correspond to each other to allow the first sensor 51A to sense the first locator 55A, and the second locator 56A and the fourth sensor 54A correspond to each other to allow the fourth sensor 54A to sense the second locator 56A. It is understood that the processor 58A can control the operating state of the driving motor 45A according to the sensing signals of the first sensor 51A and the fourth sensor 54A after sensing the first positioner 55A.

It should be noted that when the circuit breaker is in the on state, the first end 462A keeps a certain preset distance from a sliding surface of the operating member 433A, and then the handle 31A drives the fourth gear 44A to rotate, so that the gear end 441A does not touch the third gear 43A.

Fig. 26 shows a positional relationship among the manual switching mechanism 30A, the automatic switching mechanism 40A, and the measurement mechanism 50A when the circuit breaker controls the electric control mechanism 20A to switch from the on state to the off state in the automatic mode. When the rotor of the driving motor 45A rotates to provide a driving force, on one hand, the driving motor 45A drives the first gear 41A to rotate, the first gear 41A drives the second gear 42A to rotate, the second gear 42A drives the third gear 43A to rotate, the third gear 43A enables the operating member 433A to contact with the first end 462A of the shift lever 46A during the rotation process to drive the first end 462A of the shift lever 46A, at this time, the shift lever 46A further transmits the driving force transmitted by the third gear 43A to the adjusting portion 22A through the driving member 24A to allow the adjusting portion 22A to be released, so that the pivot end 221A of the adjusting portion 22A rotates relative to the housing 10A under the action of the torsion spring of the adjusting portion 22A to further drive the mounting end 311A of the handle 31A to rotate relative to the housing 10A And the operating end 312A of the handle 31A is driven to swing downwards, while the mounting end 311A of the handle 31A drives the fourth gear 44A to rotate through the pivot shaft 33A when rotating; on the other hand, the first positioner 55A and the second sensor 52A correspond to each other to allow the second sensor 52A to sense the first positioner 55A, and the second positioner 56A and the third sensor 53A correspond to each other to allow the third sensor 53A to sense the second positioner 56A.

Fig. 27 shows a process in which the circuit breaker controls the switching of the electricity control mechanism 20A from the off state to the on state in a manual mode, and fig. 28 shows a positional relationship of the manual switching mechanism 30A, the automatic switching mechanism 40A, and the measuring mechanism 50A when the circuit breaker is in the on state. However, in this embodiment, when the breaker is in the off state and the relative position of the handle 31A to the housing 10A is changed, the first end 461A acts on the stop end 4331A, so the third gear 43A is not driven by the fourth gear 44A due to the force of the lever 46A, and the state of the lever 46A cannot be controlled by arbitrarily adjusting the change of the handle 31A.

In this embodiment, when the circuit breaker is in the off state, before the position of the second gear 42A in the housing 10A is changed, the second gear 42A rotates, that is, the first positioner 55A starts to correspond to the second sensor 52A, and after the rotation, the first positioner 55A is used for the first sensor 51A. When the second gear 42A rotates, the third gear 43A is driven to rotate, and the stop end 4331A cannot act on the first end 462A. When the circuit breaker is in the open state, the operating member 433A acts on the first end 462A, so that the handle 31A drives the fourth pulley 44A to rotate arbitrarily, the change of the shift lever 46A cannot be changed, and the shift lever 46A is kept in a stationary state by the operating member 433A. In order to adjust the circuit breaker from the off state to the on state, the second turning wheel 42A needs to be turned from the position corresponding to the second sensor 52A to the position corresponding to the first sensor 51A, so that the operating element 433A does not act on the first end 462A, and the lever 46A is still operated.

At this time, when the handle 31A is pulled up, the fourth gear 44A is rotated, because the teeth of the fourth gear 44A correspond to the portion of the third small wheel 432A of the third gear 43A where no teeth are provided, and therefore, when the fourth gear 44A is rotated by the handle 31A, the fourth gear 44A is prevented from contacting with the third gear 43A. In addition, when the handle 31A is pulled up, the handle 31A drives the lever 46A to rotate relative to the housing 10A through the adjusting portion 22A and the driving member 24A.
