Claim 2:
3. The electric switching apparatus according to claim 2, wherein the breaker body enters the drawer apparatus, and sequentially passes through the separation position, the trial position, the connected but not clamped position and the connected and clamped position;
in the separation position, the main shaft is located at the separation angle, the bifurcated first driving rod is located in the first driving groove, the bifurcated second driving rod is located in the second driving groove, the unlocking rod does not act with the unlocking groove, and the interlocking rod does not act with the interlocking groove;
moving from the separation position to the trial position, the sliding plate moves towards the inner side of the drawer apparatus, an outer side end of the first driving groove pushes the bifurcated first driving rod, an outer side end of the second driving groove pushes the bifurcated second driving rod, so that the main shaft rotates to the trial angle, the unlocking rod does not act with the unlocking groove, and the interlocking rod does not act with the interlocking groove;
moving from the trial position to the connected but not clamped position, the sliding plate moves towards the inner side of the drawer apparatus, the outer side end of the first driving groove pushes the bifurcated first driving rod until the bifurcated first driving rod disengages from the first driving groove, the outer side end of the second driving groove pushes the bifurcated second driving rod until the bifurcated second driving rod disengages from the second driving groove, so that the main shaft rotates to the connected but not clamped angle, the unlocking rod enters the unlocking groove, but the unlocking rod does not act with the unlocking groove, and the interlocking rod does not act with the interlocking groove; and
moving from the connected but not clamped position to the connected and clamped position, the sliding plate moves towards the inner side of the drawer apparatus, an outer side end of the unlocking groove pushes the unlocking rod to enable the main shaft to rotate to the connected and clamped angle, and the interlocking rod enters the interlocking groove, but the interlocking rod does not act with the interlocking groove.
