Claim:
1. A holding clamp having two clamping jaws ( 10 , 11 ), which oppose one another in a mirror image with respect to a base plate ( 1 ), and which are rotatable in dependence on one another and on axial pins ( 3 , 4 ) arranged spaced apart from one another on the base plate ( 1 ), wherein the clamping jaws ( 10 , 11 ) are connected to axial sleeves ( 5 , 6 ), which are mounted so they are rotatable on the axial pins ( 3 , 4 ), and a synchronization mechanism for transmitting a pivot movement from one to the other clamping jaw ( 10 , 11 ) is formed from at least one toothed gearing element, wherein the gearing element is formed by a toothed rack ( 25 ), which carries a toothed part ( 28 ) on each of its two opposing ends, which has a gear teeth engagement in each case with a partial set of gear teeth ( 7 , 8 ) in each case on an outer circumference of the axial sleeve ( 5 , 6 ) of the clamping jaw ( 10 , 11 ), wherein the toothed rack ( 25 ) is pre-tensioned by a spring element, which pre-tensions the clamping jaws ( 10 , 11 ) in a closed position, and an actuation of the clamping jaws ( 10 , 11 ) is performed by an object to be clamped itself, wherein a displacement of the toothed rack ( 25 ) is delimited by stop ribs ( 29 , 30 ) on a bottom side of the base plate ( 1 ).
