Tensioning device, in particular a machine vice with a quick-tension means

A tensioning device, comprising:

• a base body;
• a stationary jaw connected to the base body;
• a movable jaw attached to the base body opposite the stationary jaw;
• a tension rod mounted to the base body and engaged to the movable jaw for adjusting the movable jaw;
• a compression rod having a longitudinal axis and defining a sleeve at least partly enveloping the tension rod, the tension rod defining a support bearing for the movable jaw by which support bearing the movable jaw is supported by the compression rod on the base body;
• the compression rod having catch surfaces into which counter surfaces of the movable jaw are engaged;
• the movable jaw being lockable at a plurality of distances from the stationary jaw with the compression rod;
• and
• the compression rod sleeve having a tensioning position in which the movable jaw is supported on the tension rod via the sleeve, and an adjusting position in which the movable jaw is displaceable relative to the base body, the sleeve being rotatably mounted about its longitudinal axis.
