In order to facilitate understanding of the starting sheet cathode according to the embodiment of the present invention, the following explains the working principle of the starting sheet cathode: when the novel self-locking device is in operation, the upper part of the poking rod 3.6 is poked to drive the self-locking pressing block 3.5 to be opened upwards, namely the lower end of the self-locking pressing block is separated from the conductive clamping piece 3.4 in the shell 3.1 by a certain distance, then the starting sheet 2 is inserted into a gap between the first shell 3.1 and the second shell 3.2 by a certain depth along the vertical direction, and the upper part of the poking rod is poked in the opposite direction, so that the poking rod drives the self-locking pressing block to move inwards to press the starting sheet on the conductive clamping piece 3.4 in the first shell 3.1. At this time, the gravity center of the self-locking pressing block 3.5 is positioned at the inner side of the self-rotation hinge point, and the self-locking pressing block 3.5 has a tendency of rotating and tilting towards the side of the starting sheet 2, so that a certain extrusion force is generated on the starting sheet 2 by the gravity of the self-locking pressing block 3.5, and self-locking is formed. After the starting sheet is fixed in the conductive clamp 3, a complete cathode for electrolysis and electrodeposition is formed, and finally, the transfer equipment hooks or grabs the conductive rod 1 to transfer the cathode into the electrolysis or electrodeposition tank, and the self-locking pressing block 3.5 forms self-locking on the starting sheet 2 in the transfer process, so that the tendency that the starting sheet 2 slips off the conductive clamp 3 is avoided. After the electrolysis or the electrodeposition is finished, the starting sheet 2 is changed into an electrolysis sheet or an electrodeposition sheet finished product is transported out, after the electrolysis sheet or the electrodeposition sheet finished product is transported to related equipment, the stirring rod 3.6 drives the self-locking pressing block 3.5 to leave the starting sheet 2 through the reverse operation, then the electrolysis or the electrodeposition product formed by the starting sheet 2 falls on subsequent output equipment, and the conductive rod 1 and the conductive clamp continuously clamp the new starting sheet to work.
