The power-off trigger button 902 is pressed down by the gravity of the maintenance tool in the tool placement slot 802, so that the vacancy warning light 901 used in conjunction with the power-off trigger button 902 is always in the off state. After the maintenance tool inside the corresponding tool placement slot 802 is taken out, the corresponding power-off trigger button 902 that loses the gravity pressure inside the tool placement slot 802 will reset and start itself, causing the corresponding vacancy warning light 901 to emit a vacancy light prompt.
