s2: at the moment, a worker needs to rotate the side block (20) at the bottom, so that the side block (20) drives the threaded rod (19) to rotate, the threaded rod (19) drives the movable block (22) to slide in the inner cavity of the transverse groove (21) through the threaded connection of the movable block (22), the movable block (22) further drives the push rod (17) to move, the push rod (17) pushes the clamping block (14) to move, and the installation of the switch shell (4) is reinforced through the movement of the clamping block (14);
s3: then, the worker moves the two support plates (9) to the top and the bottom of the side plate (11), then rotates the bolt (10), enables the bolt (10) to be in threaded connection with an inner cavity of the threaded groove (12), fixes the support plates (9) and the side plate (11), further fixes the inner shell (24), and at the moment, the connecting rod (8) on the left side of the inner shell (24) is located at the bottom of the shifting piece (6);
s4: when the current in the switch shell (4) is too large, and a circuit is short, the shifting piece (6) can be separated under the action of the release (5) to move downwards, and at the moment, the connecting rod (8) on the pulley (7) can be pushed to drive the left rack (25) to move by the connecting rod (8), the right rack (25) is driven by the gear (28) to move upwards, and the right rack (25) drives the bottom power-on block (32) to be contacted with the top power-on block (32) through the vertical rod (31);
s5: at the moment, the colored lamp (13) on the right side of the cabinet body (1) is turned on to remind a user that a circuit on the inner wall of the cabinet body (1) has a short circuit or other faults and needs to be overhauled or other maintenance procedures;
s6: through the radial setting that is greater than the left side radius of air hose (33) right side for when the cabinet body (1) flows with the shell air, because atmospheric pressure changes, under the effect of pressure, the steam of outside air can suitably reduce, further makes the inside radiating effect of the cabinet body (1) better.
