step two: when a push rod (41) on the pushing mechanism (4) is pushed by a cam (34), a slide rod (43) on the side wall of the push rod (41) can slide in the first inner groove (21), a slide block (44) on the slide rod (43) can slide in the second inner groove (22), a moving rod (45) fixed at the end part of the push rod (41) can drive a fixing head (46) to move together, so that the fixing head (46) can be abutted against the surface of a clamping head (63), the clamping head (63) can drive a baffle (62) to move synchronously, the baffle (62) can extrude a first spring (61) when moving, the first spring (61) is compressed in the third inner groove (23), after the fixing head (46) slides through the clamping head (63), under the action of the first spring (61), the first spring (61) can push the baffle (62), and the baffle (62) can move to drive the clamping head (63) integrally formed with the baffle (62) to move, the clamping joint (63) can be clamped at the other side of the fixing head (46) so as to limit the fixing head (46), in the moving process of the push rod (41), the push rod (41) can drive the push rod (52) on the reset mechanism (5) to move, and the push rod (52) can push the push plate (51) to move towards the direction far away from the protective shell (2);
step three: when the pushing mechanism (4) is driven by the transmission mechanism (3), the push rod (41) on the pushing mechanism (4) moves, and the push rod (41) moves synchronously through the power-off mechanism (8) arranged at the bottom of the push rod in the moving process, so that the contact head (82) on the side wall of the conducting strip (81) on the power-off mechanism (8) moves away from the inside of the contact groove (75) on the energized copper sheet (71) on the energizing mechanism (7), and is powered off, and the conducting wire (74) cannot form a closed loop through the conducting strip (81) and the conducting wire (74) connected with the conducting strip (81), thereby achieving the function of power-off protection and having high safety performance;
step four: when the power needs to be switched on, the push plate (51) made of the insulating material is pushed by hand, the push plate (51) can drive the push rod (52) to move, the push rod (52) can drive the push rod (41) to move synchronously when moving, and in the process of resetting the push rod (41), the moving rod (45) fixed on the push rod (41) can drive the fixed head (46) to move towards the initial position, so that the fixed head (46) can abut against the surface of the clamping head (63), the clamping head (63) drives the baffle plate (62) to move synchronously, the baffle plate (62) can extrude the first spring (61) when moving, when the fixed head (46) slides through the clamping head (63), under the action of a spring, the clamping joint (63) is clamped at the other side of the fixed head (46), thereby limiting the fixed head (46) at one side of the clamping head (63), and at the moment, the fixed head (46) and the clamping head (63) are mutually abutted; in the moving process of the push rod (41), a contact head (82) of the side wall of a conducting strip (81) arranged below the push rod (41) is firstly contacted with the clamping groove under the action of a second spring (84), after the push rod (41) continuously moves, the conducting strip (81) rotates around a rotating pin (83), and when the clamping head (63) and the fixing head (46) are clamped, the conducting strip (81) rotates to be parallel to the electrified copper sheet (71), so that the electrified mechanism (7) is stably conveyed.
