In the normal state of the PLC controller of the operation cabinet 200, the sliding block 103 is squeezed by the elastic member 101d, and the sliding block 103 is also sucked by the suction electromagnetic lock 102, so that the sliding block 103 is fixed. At this time, the sliding block 103 blocks the operation hole 102a-1, and the first operating handle 102b is located below the sliding block 103 to avoid accidental touch. When the manual dial block 103a is dialed to make the sliding block 103 slide toward the side away from the suction electromagnetic lock 102, when the side surface of the sliding block 103 contacts the inner side surface of the sliding member 101, the inclined block 104a falls into the limiting inclined groove 103c. At this time, the sliding block 10 3 is in the limit state, and the electromagnetic relay 105 is under the control state of the PLC controller. When the sliding block 103 needs to be released from the limit, the electromagnetic relay 105 is energized to generate magnetism so that the metal limit block 104b of the limit member 104 is adsorbed by the suction force of the electromagnetic relay 105, so that the limit member 104 slides upward and the inclined block 104a is separated from the limit inclined groove 103c. When a problem occurs in the PLC controller, in order to make the limit member 104 and the sliding block 103 contact from the limit state, the limit state can also be released by pushing the manual operation handle 104c upward, so that the operator can quickly switch to manual operation.
