  • Patent number: 5954314
    Abstract: A spring vice (1) compression springs (31), comprising a spindle drive with a threaded spindle and two tensioning claws (2, 17) of an approximately fork-shaped design, wherein the tensioning claws (2, 17) can be moved toward each other by actuating the threaded spindle. To make it possible to apply strong tensioning forces for tensioning compression coil springs and to guarantee a simple exchangeability of the tensioning claws (2, 17) at the same time, the two tensioning claws (2, 17) are provided with a mounting cylinder (3, 16), which forms a kind of bayonet catch together with the spindle drive. This bayonet catch is optimally suitable for absorbing strong tensioning forces and permits a simple replacement of tensioning claws (2, 17) without problems.
