The slider 92 which is arranged to move linearly cooperates with the baffle 93, the locking piece 94 and the micro switch 95 respectively, so that the dual power supply of the dual power supply switching switch is cut off and the padlock is locked, which plays a role in electricity safety protection. At the same time, the slider 92 which moves linearly drives the baffle 93 to rotate in an articulated manner, so that the baffle 93 does not need to be additionally set with a reset structure, the structure is simplified, the action relationship is simple and reliable, and the reliability of the padlock function is improved. The baffle 93 is rotatably set, and occupies less space.

[0047] The micro switch 95 is used to switch the manual mode and the automatic mode of the dual power switch, and can be used in a variety of ways. For example, the micro switch 95 is used to control the activation and deactivation of the transmission mechanism 6. The micro switch 95 is connected in series in the power supply circuit of the transmission mechanism 6, or the micro switch 95 is connected to the control circuit of the transmission mechanism 6, and is only used to feedback the activation or deactivation signal, and the control circuit controls the activation or deactivation of the transmission mechanism 6 according to the feedback signal. The micro switch 95 can be a normally closed micro switch or a normally open micro switch. In this embodiment, the slider 92 triggers the micro switch 95 to switch the state, which means that the slider 92 presses the trigger rod of the micro switch 95 or avoids the trigger rod of the micro switch 95, so that the micro switch 95 is switched to a closed or open state; for example, when the slider 92 moves linearly to the automatic position, the slider 92 can press the trigger rod of the micro switch 95 to switch the micro switch 95, or avoid the trigger rod of the micro switch 95 to switch the micro switch 95, so that the transmission mechanism 6 is activated, which belongs to the protection scope of this application.
