Anti-overheating safe-to-use disconnecting switch for electric power construction

The invention belongs to the technical field of disconnecting switches, particularly relates to an anti-overheating safe-to-use disconnecting switch for electric power construction. Aiming at the problems that when an existing disconnecting switch is used, if the temperature is too high, a device cannot be well protected, a constructor cannot be effectively reminded, and the use efficiency is greatly reduced, the disconnecting switch comprises a switch frame body, the bottom of the switch frame body is slidably provided with a mounting device, the bottom of the switch frame body is rotatably provided with an adjusting device, the top of the switch frame body is fixedly provided with a top plate, the top of the top plate is slidably provided with a transverse plate, and the left side of the transverse plate is fixedly provided with a first contact switch; and the top of the top plate is fixedly provided with a second contact switch, and the right side of the transverse plate is fixedly provided with a first se
