[0030] The working principle of the embodiment is as follows:

[0031] (1) As shown in Figure 6 , when the conductive plug 11 of the plug is inserted into the socket, the top rod 7 is pressed to trigger the limit micro switch 6 to open, the overcurrent relay does not act due to no overcurrent, the electric leakage protector does not work due to no power supply, the power supply and the motor 5 are connected in forward direction, and the motor 5 starts to work. The motor 5 drives the eccentric wheel shaft 10 to rotate through the driving mechanism, the eccentric wheel shaft 10 drives the eccentric pressure wheel 3 to rotate, the outer circle movement track of the eccentric pressure wheel 3 gradually increases when the eccentric pressure wheel 3 rotates, so that the conductive plug 11 is gradually pressed against the conductive sheet 4, and the working target of connecting the circuit is achieved.

[0032] (2) As shown in Figure 7 , when the eccentric pressure wheel 3 continues to rotate and the motor reaches the set locked-rotor current, the current is over, the overcurrent relay loses power, the first contact LG-K1 of the overcurrent relay is switched to the closed state, the electric leakage relay is powered, the JD-K1 and JD-K2 controlled by the electric leakage relay are switched to the open state, the JD-K3 attracts to keep the power supply state of the electric leakage relay, the motor stops working due to the disconnection of the motor and the power supply caused by the disconnection of JD-K2, and the conductive sheet 4 and the conductive plug 11 remain in the pressed state.

[0033] (3) As shown in Figure 8 , when the conductive sheet 4 and the conductive plug 11 are not needed to be connected, FK is pressed, the fixed ends of FK-K1, FK-K2 and FK-K3 are connected to the second moving ends, the overcurrent relay and the electric leakage relay lose power, the motor 5 is reversely connected with the power supply through FK-K1 and FK-K2, the motor 5 drives the eccentric wheel shaft 10 to reversely rotate through the driving mechanism, and then drives the eccentric pressure wheel 3 to reversely rotate, the outer circle movement track of the eccentric pressure wheel 3 gradually decreases, the conductive plug 11 is gradually released from the conductive sheet 4, and the electric leakage relay returns to the initial state due to the disconnection of FK-K3. After the conductive plug 11 is pulled out, the conductive plug 11 and the conductive sheet 4 are disconnected, the limit micro switch 6 is reset, the reverse button switch FK is pressed and closed, and the whole device returns to the initial state.
