Support arrangement for supporting a workpiece

A support arrangement for supporting a workpiece at a processing device during processing of the workpiece, the support arrangement comprising:

• a fixating means adapted to be pivoted about an axis of a connecting means to arrange an abutment surface of the support arrangement in contact with one side of the workpiece when another opposite side of the workpiece abuts one or more fences of the processing device, the fixating means comprising a first excentre having a circumference with a varying distance perpendicular to the axis and a first pitch,
• a locking means adapted to lock the fixating means in a contact position where the abutment surface of the support arrangement abuts the one side of the workpiece when another opposite side of the workpiece abuts the one or more fences of the processing device, wherein the locking means comprises a second excentre with a second pitch different than the first pitch and which is adapted to be pivoted about the axis of the connecting means to a lock position wherein the fixating means is locked in the contact position and
• the connecting means is adapted to connect the support arrangement with the processing device and wherein the connecting means extends along the axis.
