Workpiece clamping device with coupling body between clamping body and threaded spindle

A workpiece clamping device, comprising:

• a first base body and a second base body that are each configured to be arranged on a support,
• a first clamping body movably supported on the first base body in a clamping direction and a second clamping body movably supported on the second base body in the clamping direction,
• a threaded spindle extending in clamping direction along a spindle longitudinal axis and comprising a first thread section for the first clamping body and a second thread section for the second clamping body,
• wherein the first clamping body has a first coupling body and the second clamping body has a second coupling body, the first coupling body and the second coupling body movable between a coupling position and a decoupling position, the first coupling body has a first counter thread portion on an end assigned to the threaded spindle that is in engagement with the first thread section in the coupling position and is disengaged from the first thread section in the decoupling position and the second coupling body has a second counter thread portion on an end assigned to the threaded spindle that is in engagement with the second thread section in the coupling position and is disengaged from the second thread section in the decoupling position and wherein the first clamping body remains movably supported on the first base body in the clamping direction and the first clamping body is slidable with respect to the first base body and the second clamping body remains movably supported on the second base body in the clamping direction and the second clamping body is slidable with respect to the second base body, independent whether the first coupling body or the second coupling body is in the coupling position or in the decoupling position.
