PURPOSE: A device for transforming handrails is provided to prevent a piston rod from sliding from the handrail by having a concave curved surface corresponding to the outer surface of the handrail where the end of the piston rod is formed in a pipe shape. CONSTITUTION: A device for transforming handrails comprises a handrail fixing unit (100), a stress applying unit (200), and a driving pressure supply unit (300). The handrail fixing unit is fixed to the handrail. The stress applying unit applies driving pressure to a piston rod vertically closed to the handrail and transforms the handrail. The driving pressure supply unit supplies the driving pressure to the stress applying unit. |
