Claim 3:
4. The electric switching apparatus according to claim 3, wherein the breaker body exits the drawer apparatus, and sequentially passes through the connected and clamped position, the connected but not clamped position, the trial position and the separation position;
in the connected and clamped position, the main shaft is located at the connected and clamped angle, the interlocking rod is located in the interlocking groove, the unlocking rod is located in the unlocking groove, the bifurcated first driving rod does not act with the first driving groove, and the bifurcated second driving rod does not act with the second driving groove;
moving from the connected and clamped position to the connected but not clamped position, the sliding plate moves towards the outer side of the drawer apparatus, an inner side end of the interlocking groove pushes the interlocking rod until the interlocking rod disengages from the interlocking groove, so that the main shaft rotates to the connected but not clamped angle, the unlocking rod is located in the unlocking groove, but the unlocking rod does not act with the unlocking groove, the bifurcated first driving rod does not act with the first driving groove, and the bifurcated second driving rod does not act with the second driving groove;
moving from the connected but not clamped position to the trial position, the sliding plate moves towards the outer side of the drawer apparatus, an inner side end of the unlocking groove pushes the unlocking rod, so that the main shaft rotates from the connected but not clamped angle to the trial angle, the bifurcated first driving rod enters the first driving groove, the bifurcated second driving rod enters the second driving groove, the inner side end of the unlocking groove pushes the unlocking rod until the unlocking rod disengages from the unlocking groove, an inner side end of the first driving groove continues to push the bifurcated first driving rod, and an inner side end of the second driving groove continues to push the bifurcated second driving rod, so that the main shaft rotates to the trial angle; and
moving from the trial position to the separation position, the sliding plate moves towards the outer side of the drawer apparatus, the inner side end of the first driving groove pushes the bifurcated first driving rod, and the inner side end of the second driving groove pushes the bifurcated second driving rod, so that the main shaft rotates to the separation angle, the bifurcated first driving rod is kept in the first driving groove, and the bifurcated second driving rod is kept in the second driving groove.
