Abstract:
1. A reinforced apparatus for a lever handle of a door lock, comprising: a housing provided with a recess formed thereon and at least one protruding portion disposed at a predetermined position of the housing; and a rotary member including a first side plate, a second side plate and a coiled spring disposed between the first side plate and the second side plate, the first side plate having an axial internal ring which is formed with a radially, inward extending projection and at least one axially extending protrusion, the coiled spring having a leg for abutting against the at least one protruding portion of the housing; wherein the housing is provided with a predetermined bending member; when the rotary member and the coiled spring are disposed within the recess, the bending member is adapted to be bent for a predetermined angle, so that a distance (R′) defined from the predetermined bending member to an axis of the housing is smaller than a distance (r) defined from an outer edge of the second side plate to an axis of the second side plate, thereby keeping the rotary member positioned within the recess and operated by an external force.
