Mobile guide components and devices optimizing device for use at e.g. microscopes, has adjustable power-storing unit in connection with housing and pulley for producing changeable pre-stress and/or force in traction unit

摘要

The device has a housing (9) connected with a microscope/fine mechanical device and rotatably storing a pulley (12) at an axis (11). A traction unit (10) stands in direct or indirect connection with the components or devices of the microscope/fine mechanical device over a retainer and is wound up on the pulley. An adjustable power-storing unit (15) stands in connection with the housing and the pulley for producing a changeable pre-stress and/or force in the traction unit.
