Hand-held power tool

Hand-held power tool and a display on a hand-held power tool

A method for the pressing of a press fitting, with a tube inserted into the press fitting, by way of a pressing tool, wherein the press fitting has an encircling bead in which an O-sealing ring is placed, wherein the tube ends within the press fitting and a first pressing is carried out within the bead, wherein, furthermore, a further pressing is carried out on the tube-insert side of the press fitting at a distance from the bead, the further pressing leading to press fitting and tube obtaining a conicity which prevents them being pulled off and runs in the same direction. Furthermore, the invention relates to a pressing tool suitable for carrying out the method. In order to further improve a method of the type under discussion, in particular for simplifying the handling over the course of the pressing operation, and in order to improve a pressing tool of the type under discussion, in particular in terms of handling while maintaining the functional reliability of the press connection winch is to be produced, it is proposed, in terms of the method, that the head is widened axially over the course of the pressing operation by being acted upon radially from the outside. In terms of the object, it is provided that the first pressing geometry, which is assigned to the bead, leaves the bead space at least in one direction for the axial widening of the bead.

A locking bolt for mounting a tool in a hydraulic press, it being possible for the locking bolt to move in a bolt receptacle between a locking position and a release position, with a securing element, which is located in the bolt receptacle and secures the locking position by positive engagement in the locking bolt, the locking bolt also having a securing portion, and the locking bolt being secured against movement into the release position when the securing element is located in the securing portion. The locking bolt has a longitudinal groove, in that the securing portion is formed with a securing depth in any event corresponding to a groove depth of the longitudinal groove and in that the securing portion is formed such that it is adjacent to the longitudinal groove in the circumferential direction, with a direct transition from a groove base into the securing position.
