ABSTRACT:
A manually operated tool of the type in which a grip is pivotally mounted in a housing displacing a push rod mounted in the housing in an axial direction and in a stepwise manner. The push rod extends through at least a pair of canting blocks arranged between bearings supporting the push rod. A spring resting on the housing acts on the portions of the canting block through which the push rod extends. The force applied by the spring on the canting blocks is directed against the direction of displacement of the push rod. An adjusting force periodically exerted by the grip acts on the outer portions of the canting blocks remote from the push rod. At least one braking block is provided for holding the push rod.
