The invention refers to a nailing unit powered by a pressure driven medium, working only using a driving piston. The nailing unit consists of a piston-driven collection rod (8, 34) and another in relation to the drive (1), with the collection rod toward and from the nailed object in question's movable stop (2), which can, in part, be set up against the object to be nailed as well as presenting a co-operative anti-impact (23b) with the driving rod's arranged stop (35a) set up in order to limit the driving rod's motion in relation to the stop estimated in the direction of collection.<IMAGE> |
