Roller shutter with dual operation modes

A roller shutter with dual operation modes, comprising a door frame, a roller shutter body, a driving motor, a connecting device, a rotating shaft and a connecting rod,

• wherein the roller shutter body is slidably configured on the door frame, and the driving motor is configured on the door frame;
• the rotating shaft is rotatably configured at an upper end of the door frame;
• the rotating shaft is connected with an output end of the driving motor through the connecting device;
• wherein the connecting device comprises a first connector and a second connector, the first connector is connected with the output end of the driving motor, the second connector is connected with the rotating shaft;
• the rotating shaft is movably configured on the door frame along a center axis direction, the first connector is selectively engaged or disengaged with the second connector, so that the first connector and the second connector are mutually fixed circumferentially or separated axially;
• a first end of the connecting rod is connected with the second connector so as to connect with the rotating shaft, and the first end of the connecting rod is slidable along a direction perpendicular to a central shaft of the rotating shaft, a second end of the connecting rod is connected with an upper end of the roller shutter body;
• when the connecting device is in a connected state that the first connector and the second connector are mutually fixed circumferentially, the output end of the driving motor is connected with the rotating shaft circumferentially, the driving motor is configured to drive the first connector and then drive the second connector so as to drive the connecting rod to retract or extend the roller shutter body;
• when the connecting device is in a separated state that the first connector and the second connector are separated axially, the output end of the driving motor is separated from the rotating shaft, the rotating shaft is manually operated to drive the second connector and then drive the connecting rod to retract or extend the roller shutter body.
