Abstract (en)
[origin: CN111223692A] The invention relates to a mechanism (100) for controlling the closing and opening of a current cut-off device. Specifically, the mechanism comprises two springs. When the two springs are released from a compressed state, the two springs are respectively used for closing and opening wheel rotation. Therefore, the mechanism comprises setting the two springs by means of a setting rod in a setting period. The setting rod automatically disengages in the closing period through rotation of a closing wheel, and only utilizes the mechanical energy of the spring which is connected with the wheel.
