A photosensitive resin model loading device is provided. The device includes a basic unit, a tensile loading unit, a pressure loading unit and a calibrating unit. The basic unit includes a pedestal, a frame and a supporting bar. The frame includes a top cross beam and two vertical arms. The two vertical arms are vertically fixed to the pedestal. The top cross beam is fixedly and horizontally connected to the two vertical arms. The supporting bar is horizontally disposed between the two vertical arms. The tensile loading unit is disposed between the supporting bar and the pedestal in a detachable manner, and includes a connector, a tensile loading base, a tensile screw and a tensile force sensor. The pressure loading unit is disposed between the supporting bar and the top cross beam in a detachable manner, and includes a pressure loading base, a pressurizing screw, a pressurizing force sensor and a limiting plate. The calibrating unit is disposed on the basic unit and is used for measuring levelness and perpendicularity changes of the basic unit.
