Simultaneously, the rotating shaft E54 where the swing rod 52 is positioned drives three gears N97 to synchronously rotate by a certain amplitude, the three gears N97 respectively drive three gears K94 and three gears J93 on the rotating shaft H117 to synchronously rotate by a certain amplitude through corresponding gears M96 and L95, and the three gears J93 respectively drive corresponding jackets E79 to move upwards through corresponding gears I91 and racks C90. Two sets of transmission connection are formed between the swing rod 52 and the outer sleeve E79, so that when the transmission connection between the swing rod 52 and the outer sleeve E79 is damaged and fails through the telescopic rod C75, the outer sleeve E79 can drive the copper contact A84 and the copper contact B88 to complete instant electric connection through the transmission connection between the gear N97 and the outer sleeve E79.

Thus, the first detection of the internal structure of the invention is completed, and if the copper contact A84 and the copper contact B88 are found to be not effectively propped against each other, the internal structure is damaged or is wrongly installed, and the damaged structure is replaced and reinstalled.

Then, the second and third tests were performed sequentially.

During the second detection, the rack B70 is pressed down firstly, the rack B70 drives the three gears H68 on the rotating shaft F69 to synchronously rotate by a certain amplitude, the three gears H68 respectively drive the outer sleeve C60 and the inner rod B64 of the corresponding telescopic rod B55 to separate from the limiting rod B53 on the corresponding swinging rod 52 through the corresponding rack A67, the swinging rod 52B swings back and resets under the action of the corresponding counterweight 72, and the swinging rod 52 drives the copper contact A84 to separate from the copper contact B88 instantaneously through a series of transmission. Then, the rack D111 corresponding to the second telescopic rod D100 is pressed down, so that the related inner rod E108 releases the limit on the limit rod D99, and the limit rod D99 abuts against the uppermost inner rod E108 under the action of the spring a16, thereby completing the second detection.

After the second detection is finished, the third detection is started, the rack B70 is pressed down firstly, the rack B70 synchronously rotates by a certain amplitude through driving the three gears H68 on the rotating shaft F69, the three gears H68 respectively drive the outer sleeve C60 and the inner rod B64 of the corresponding telescopic rod B55 to separate from the limiting rod B53 on the corresponding swinging rod 52 through the corresponding rack A67, the swinging rod 52B swings back and resets under the action of the corresponding counterweight 72, and the swinging rod 52 drives the copper contact A84 to separate from the copper contact B88 instantaneously through a series of transmission. Then, the rack D111 corresponding to the second telescopic rod D100 is pressed down, so that the related inner rod E108 releases the limit of the limit rod D99, and the limit rod D99 abuts against the uppermost inner rod E108 under the action of the spring a16, thereby completing the third detection.

After the third detection is finished, the rack B70 is pressed down firstly, the rack B70 drives the three gears H68 on the rotating shaft F69 to synchronously rotate by a certain amplitude, the three gears H68 respectively drive the outer sleeve C60 and the inner rod B64 of the corresponding telescopic rod B55 to separate from the limiting rod B53 on the corresponding swinging rod 52 through the corresponding rack A67, the swinging rod 52B swings back and returns under the action of the corresponding counterweight 72, and the swinging rod 52 drives the copper contact A84 to separate from the copper contact B88 instantaneously through a series of transmission.

Then, the crank 2 is continuously rocked to rotate 270 degrees, the crank 2 drives the limiting rod D99 to sequentially pass through the inner rods E108 of the three telescopic rods D100 through a series of transmission and is limited by the inner rod E108 at the lowest end, and the spring A16 is in a full-up force state. The driving lever A42 is shifted, the driving lever A42 drives the telescopic rod A116 to swing to the limit position, the telescopic rod A116 passes through the rotating shaft C34 in the middle of the crank D35 and drives the crank D35 to swing by a certain amplitude, the crank D35 drives the crank C33 to swing synchronously by a certain amplitude through the rotating shaft C34, the crank C33 drives the two gears C31 to swing synchronously, the gear C31 corresponding to the gear ring A26 is separated from the corresponding gear B30, and the gear C31 corresponding to the gear ring B27 is meshed with the corresponding gear B30.

When each copper contact A84 and each copper contact B88 are respectively communicated with corresponding electrodes and the circuit of the invention is required to be communicated, the lowest toothed bar D111 is pressed down, the toothed bar D111 drives the inner rod E108 of the corresponding telescopic rod D100 to be separated from the limiting rod D99, the moving seat A8 drives the three deflector rods B51 to swing 360 degrees through a series of transmission under the reset action of the spring A16, and each swing rod 52 drives the copper contact A84 to be instantaneously electrically connected with the copper contact B88 through a series of transmission.

When the spring A16 breaks in the process of electrically connecting the copper contact A84 and the copper contact B88, the moving seat A8 does not drive the deflector rod B51 to move through a series of transmission, at the moment, the spring B20 pulls the sliding seat 17 to move upwards, the sliding seat 17 drives the swinging rod 52 to swing rapidly through the pull rod 74 and the three springs G73, the swinging rod 52 drives the copper contact A84 and the copper contact B88 to normally complete the electrical connection through a series of transmission, the electrical connection time of the copper contact A84 and the copper contact B88 is prevented from being prolonged or not completed when the spring A16 fails, and further the problem that the occurrence time of an arc generated between the copper contact A84 and the copper contact B88 is prolonged and the burnout of the invention is avoided because the distance between the copper contact A84 and the copper contact B88 is reduced in the process that the copper contact A84 and the copper contact cannot normally complete the electrical connection. In summary, the beneficial effects of the invention are as follows: according to the invention, after the crank 2 is manually rocked to fully force the spring A16 once, the mounted structure is continuously detected three times through the cooperation of the limiting rod D99 and the three telescopic rods D100, the force is not required to be detected once, and the detection efficiency of the mounted internal structure is improved.

According to the invention, when the force storage spring A16 fails, the swing rod 52 can quickly drive the copper contact A84 and the copper contact B88 to be switched on under the action of the spring B20 and the spring G73, so that the switching-on time of the circuit breaker when the force storage spring A16 fails is shortened, the occurrence time of electric arcs generated during switching-on is shortened, and the circuit breaker is prevented from burning out due to the fact that the electric arcs are generated for a long time due to low switching-on speed when the force storage spring A16 fails.

The transmission connection between the swing rod 52 and the outer sleeve E79 in the invention adopts a double-safety structure, so that the transmission connection between the swing rod 52 and the outer sleeve E79 can still ensure the smooth closing and opening of the circuit breaker when the hinge fails.
