Claim 0:
1. An electric switching apparatus, characterized in comprising:
a drawer apparatus, and a breaker body enters or exits the drawer apparatus;
an electric connection apparatus, being installed on the drawer apparatus, the electric connection apparatus includes a clamping mechanism, and the electric connection apparatus connects a busbar of the breaker body and an external circuit;
a driving mechanism, driving the breaker body to move, so that the busbar of the breaker body enters or leaves an area of the electric connection apparatus; and
a locking mechanism driven by the driving mechanism that drives the clamping mechanism of the electric connection apparatus, so that the electric connection apparatus clamps or loosens the busbar of the breaker body;
wherein the driving mechanism drives the breaker body to move, a relative position of the breaker body and the drawer apparatus includes:
a separation position, in which the breaker body is separated from the electric connection apparatus, and the breaker body cannot be switched on;
a trial position, in which the breaker body is separated from the electric connection apparatus, and the breaker body can be switched on;
a connected but not clamped position, in which the breaker body is in touch with the electric connection apparatus, the electric connection apparatus does not clamp the busbar, and the breaker body cannot be switched on; and
a connected and clamped position, in which the breaker body is in touch with the electric connection apparatus, the electric connection apparatus clamps the busbar, and the breaker body can be switched on;

wherein the driving mechanism is installed on the drawer apparatus, and the driving mechanism comprises:
a driving shaft, one end of the driving shaft is connected to a handle, and the handle is rotated to drive the driving shaft to rotate:
a sliding plate, installed on the driving shaft, a rotation of the driving shaft is converted into a sliding of the sliding plate, the driving shaft drives the sliding plate to move, and the sliding plate moves towards an inner side or an outer side of the drawer apparatus to drive the breaker body to enter or exit the drawer apparatus;
a main shaft, installed on the drawer apparatus, the main shaft matches with the sliding plate, when the sliding plate moves to the separation position, the trial position, the connected but not clamped position and the connected and clamped position, the main shaft correspondingly rotates to a separation angle, a trial angle, a connected but not clamped angle and a connected and clamped angle; and
a supporting plate, installed on the drawer apparatus, the supporting plate drives the breaker body to move and matches with the main shaft, when the main shaft rotates to the separation angle, the trial angle, the connected but not clamped angle and the connected and clamped angle, the supporting plate drives the breaker body to the separation position, the trial position, the connected but not clamped position and the connected and clamped position.
