Disclosed is a cantilever, including: a spar connected rotatably about a rear fixed axis to a fastening device for a vehicle; a tool lever connected rotatably about a front fixed axis to the spar; a deflecting triangle connected rotatably about a central fixed axis to the spar; a rear strut connected rotatably about a first strut pivot axis to the fastening device and rotatably about a second strut pivot axis to the deflecting triangle; a front strut connected rotatably about a third strut pivot axis to the deflecting triangle and rotatably about a fourth strut pivot axis to the tool lever. The rear and the central fixed axis span a first plane, the rear strut intersects the first plane, the central and the front fixed axis span a second plane, and the front strut intersects the second plane.
