ABSTRACT:
A power supply early warning device for pulling out a power plug is composed of a power supply, which is loosely connected with a handle, with the handle being installed with a locking hole. A long through-hole is installed at a side edge of the power socket, and a locking member is provided with a pushing plate, with an end of which being formed with a projection piece. the locking member is installed with a locking plate which can be locked or loosely connected into the long through-hole, and the pushing plate can be slidingly displaced on an outer wall of a rim of the long through-hole, allowing the projected piece to be locked into or released from the locking hole of the handle, so as to prevent from a deformation or a short-circuiting between the power plug and the socket by a dragging of external force, and to further enable a user to displace the power supply more safely, without damaging the entire power supply system.
