ABSTRACT:
A torsion spring positioning device of a cylindrical lock includes a spindle outer casing through which a spindle extends and the spindle outer casing has two protrusions extending radially inward from an inner periphery thereof. The spindle has two slots defined in a periphery thereof and two stops extending radially outward from the periphery thereof so that two legs of the torsion spring respectively abut an end of the corresponding stop and an end of the corresponding protrusion. A washer is mounted to the spindle and has two notches defined in an outer periphery thereof so as to respectively receive the protrusions. A C-shaped clamping member is mounted to the spindle and has two stubs extending radially inward from an inner periphery thereof so as to be received in the slots.
