Abstract: An unlocking device with a pause function comprises a first moving member having a first protruding portion, a second moving member having a second protruding portion, and a third moving member having a third end portion and a fourth end portion. The second moving member is disposed corresponding to the first moving member. The second protruding portion is disposed cooperated with the first protruding portion. The third end portion is connected to the second moving member. When the fourth end portion of the third moving member contacts a carry body, and a first end portion of a releasing member moves along a first direction towards the housing, the releasing member drives the first moving member to move in the first direction, so the second moving member holds the position of the releasing member by the second protruding portion and the first protruding portion.
Abstract: A portable charger includes a housing, a first plug-in assembly, and a charging assembly. The housing comprises an accommodating cavity and an avoidance recess formed in an outer surface. The first plug-in assembly includes a first plug rotatably connected to the housing and a locking element movably connected to the housing. The first plug is rotatable between a plug-in position where the first plug is protruding out of the outer surface of the housing and a storage position where the first plug is accommodated in the avoidance recess. The locking element is movable between a stop position limiting the rotation of the first plug at the storage position and an unlocking position avoiding from the first plug. The charging assembly includes a battery and a control board both arranged in the accommodating cavity. The control board is electrically connected to the first plug and the battery.
