The clamp/stand unit has a spring to generate a clamping force. A leaf spring (3) has three parallel rod-shaped support rods (4-6), which are stationary or adjustable, and are at relative distances. The supports extend along a path, which is parallel to the leaf spring surface, from one longitudinal edge (7) of the spring at right angles in the same direction. One support is fastened to each end of the spring, with the third one in the centre. Two of the supports may be rigidly connected, and be in contact with the third one via the spring. The central spring may carry a hinged retainer arm (12). |
