[0029] Reference Figure 1-7 , when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that:

[0030] The inner side of the energy storage handle 2 corresponds to the column 3 and the primary force handle 4 is provided with a matching storage groove, the middle part of the outer ring surface of the primary force handle 4 is provided with an anti-slip sleeve 8, the end of the secondary force handle 7 located outside the primary force handle 4 is provided with a holding protrusion 9, the holding protrusion 9 is arc-shaped, the end of the secondary force handle 7 located inside the primary force handle 4 is provided with a magnetic suction block 10, and the magnetic suction block 10 is provided inside the primary force handle 4. A matching adsorption sheet 11 is provided; the arrangement of the storage groove is convenient for the primary force handle to be held when the circuit breaker is not operated. The handle 4 and the secondary boosting handle 7 are stored, and the anti-slip cover 8 is provided, which makes it convenient for personnel to firmly hold the primary boosting handle 4 to avoid hand slippage when the personnel store energy. The holding protrusion 9 is provided, which not only makes it convenient for personnel to pull the secondary boosting handle 7 out from the inside of the primary boosting handle 4, but also has a blocking effect on the personnel's hands to a certain extent to prevent the personnel's hands from slipping off the boosting handle when applying force. The magnetic block 10 and the adsorption sheet 11 are provided, which makes it convenient for the secondary boosting handle 7 to be stored in the primary boosting handle 4.

[0031] The inner side of the end of the primary force-adding handle 4 is provided with a matching positioning groove 12 corresponding to the squeezing bead 6, and the positioning groove 12 is a smooth surface. The end of the primary and secondary fusion circuit breaker body 1 is provided with a matching mounting frame 13 corresponding to the energy storage handle 2, and the lower side of the mounting frame 13 is provided with a matching protective cover 14, and the protective cover 14 cover body is a transparent cover body, and the protective cover 14 and the mounting frame 13 are connected by a lock. A traction rope is provided between the lower side of the protective cover 14 and the mounting frame 13; the setting of the positioning groove 12 makes it easy for the squeezing bead 6 to position the primary force-adding handle 4 and a certain The fixing degree is high, that is, when the personnel unfold the primary booster handle 4, the position of the primary booster handle 4 can be fixed by the cooperation between the squeezing bead 6 and the positioning groove 12 to prevent it from rotating at will. The setting of the mounting frame 13 and the protective cover 14 can protect the opening handle, the energy storage handle 2 and the pointer at the end of the circuit breaker, thereby delaying the damage of the handle, the pointer and other parts.

In this process, the personnel can rotate the primary force-adding handle 4, so that the primary force-adding handle 4 is unfolded from the storage slot of the energy storage handle 2. At this time, the personnel can hold the primary force-adding handle 4 to drive the energy storage handle 2 to shake, thereby amplifying the torque applied to the energy storage handle 2 by extending the force arm, that is, the personnel can operate the energy storage handle 2 more easily and labor-savingly, and at the same time the personnel can pull out the secondary force-adding handle 7, and then further The force arm is further extended, that is, the degree of labor saving is further improved, so that the personnel can drive the energy storage handle 2 with less effort, thereby effectively reducing the personnel's manpower input and reducing the soreness of the personnel's hands. At the same time, since the one-time force-adding handle 4 can be rotated, the personnel can adjust the angle of the one-time force-adding handle 4 as appropriate according to their own operating conditions, so that the hand is more comfortable when applying force. Therefore, with the mutual cooperation of various components, this scheme, compared with the traditional scheme, can not only effectively reduce the personnel's manpower input when in use, but also allow the personnel to shake the energy storage handle 2 more comfortably, thereby effectively avoiding the soreness caused by excessive force and discomfort in the hands during operation, that is, it is conducive to the personnel operating the circuit breaker on the column.

[0033] It should be further explained that the arrangement of the storage groove facilitates the storage of the primary force handle 4 and the secondary force handle 7 when the circuit breaker is not in operation. The arrangement of the anti-slip sleeve 8 facilitates the personnel to firmly hold the primary force handle 4 to prevent the personnel from slipping when storing energy. The arrangement of the holding protrusion 9 not only facilitates the personnel to pull the secondary force handle 7 out of the primary force handle 4, but also has a blocking effect on the personnel's hands to a certain extent to prevent the personnel's hands from slipping off the force handle when applying force. The arrangement of the magnetic block 10 and the adsorption sheet 11 facilitates the storage of the secondary force handle 7 into the primary force handle 4; Positioning groove The setting of 12 makes it easy to squeeze the bead 6 to position and fix the primary force handle 4 to a certain extent, that is, when a person unfolds the primary force handle 4, the position of the primary force handle 4 can be controlled by the cooperation between the squeezing bead 6 and the positioning groove 12 to prevent it from rotating at will. The setting of the mounting frame 13 and the protective cover 14 can protect the opening handle, the energy storage handle 2 and the pointer at the end of the circuit breaker, thereby delaying the damage of the handle, the pointer and other components. At the same time, the setting of the traction rope ensures that after the person removes the protective cover 14, the protective cover 14 will not fall directly to the ground, thereby facilitating the person to reset the protective cover 14 after the operation.
