Abstract:
An apparatus for receiving and positioning an object, the apparatus comprising: a base plate (1) with a support surface thereon (3) and a stop located on one side of the support surface (3), the stop limiting displacement of the object when positioned said support surface (3); a clamping device mounted on said base plate having a slide (6) with a clamping plate (10) for exerting a force on the object, the clamping plate (10) facing the stop and being mounted to be linearly drawn back together with the slide (6) relative to the stop against an initial tension; the clamping device further comprising a lever (12) pivotably connected at a first end to the base plate (1) by an axle that extends parallel to the support surface (3) and the stop, on a second end the lever comprises a downwardly facing, oblique thrust surface (15) which is in sliding contact with an upwardly projecting, sliding extension (11) of the slide (6), so that pressing down the lever (12) on its second end pivots the lever around the axle, the oblique thrust surface (15) sliding on the sliding extension (11) and causing the slide (6) and the clamping plate (10) to slide parallel to support surface away from the stop and thereby releasing the object.
