ABSTRACT:
A wall hook includes an inserting head defining a rotational axis, and a levering handle. The inserting head has a front penetrating tip adapted for rotatably inserting into a wall surface of the wall and a rear fulcrum end rearwardly extended from the penetrating tip along the rotational axis. The levering handle has a transverse arm integrally and transversely extended from the fulcrum end of the inserting head to substantially prolong a torque distance along the transverse arm with respect to the rotational axis, and a controlling arm integrally extended from the transverse arm in such a manner that when the levering handle is rotated, the inserting head is driven to rotate for rotatably penetrating into the wall so as to minimize a torque required to directly apply at the inserting head.
