SPANNVORRICHTUNG ZUM FESTSPANNEN EINER SCHUTZHAUBE AM SPANNHALS EINER HANDWERKZEUGMASCHINE

摘要

A clamping device (10) for securing a protective hood (11) to the neck (12) of a hand machine-tool has a clamping strip (13) and a clamping lever (18) in the regions of its ends (16 and 17). The lever can be pivoted with one end (19) about an axis (20) in relation to the end (16) of the clamping strip (18) at that point. The lever (18) engages with a transmission member (21) which engages at a distance therefrom with the second end (17) of the clamping strip and, on being tightened, brings the ends of the strip together. The transmission member (21), the lever (18) and the clamping strip ends (16 and 17) are designed so that they form an articulated lever device which pulls the strip (13) together during tightening. At its ends the strip is subjected virtually only to tension. There are no undesirable bending moments at that point. The tension is distributed over a wide area. The lever (18) can be easily operated.
