Operating principle
The pincer grip is a double actuator grip. The pincer grip is opened and closed via a clamping lever.
The prestressed spring holds the specimen grip open for specimen insertion. If the specimen grip is closed, the prestressed spring generates the required gripping force.
The gripping force is increased proportionally by the pincer principle as the tensile force increases. This ensures automatic retightening for specimens prone to shrinkage.
