Abstract
A pressing tool having a drive unit, a piston-cylinder unit with a fork-like receiver and an actual clamping pincer. The clamping pincer has a T-shaped mounting which, with a retaining bolt and a retaining bolt receiver, is connected to a fork-like receiver. In the fork-like receiver, a roller holder with two rollers is located. The fork-like receiver is part of the piston-cylinder unit. On actuation of the pressing tool, the piston-cylinder unit is pulled back and thus the roller holder with the rollers is moved forward relative thereto in an axial direction towards the clamping pincer. Thus, the rollers roll on roll flanks of the clamping jaws of the clamping pincer. The clamping pincer is pressed together by the rollers pressing apart the clamping jaws at the rear. Thus, the rollers are supported on a bearing block with sliding bearing surfaces. In the region between contact surfaces of the rollers with the sliding bearing surfaces and the contact line of the two rollers, there is a dirt collection chamber.
