ABSTRACT:
A releasing assembly includes a lever provided with a first engaging element, a seat having a hole defined in a bottom of the seat and a cutout defined in a periphery of the seat to communicate with the hole, a releasing head having a column formed on the releasing head to extend into the hole of the seat, a second engaging element formed on a side face of the column to engage with the first engaging element and a ring formed on a bottom of the releasing head for hanging an object and a power supplying device operably connected to the first distal end of the lever to provide a force to the lever to cause the lever to pivot. When the power supplying device is activated, disengagement between the first engaging element and the second engaging element releases the releasing head.
