Abstract: A pliers includes first and second pliers parts and an articulation that pivotably connects the pliers parts. The articulation is arranged on at least one of the pliers parts between its ends. First and second handle elements associated with the first and second pliers parts. The first pliers part is connected rotation-fast to the first handle element. The second pliers part is pivotably connected to the second handle element. A coupling element that is pivotably attached to the second handle element has a hinge point arranged on the second handle element spaced apart from the hinge point of the second pliers part on the second handle element. The coupling element is also pivotably attached to the first pliers part or to the first handle element. The hinge point of the coupling element is arranged on the first pliers part or on the first handle element spaced apart from the articulation that connects the pliers parts.

Abstract: A flush cutter, having a first gripper part, having a first blade part comprising a blade, a second gripper part, comprising a second blade part having a blade, a joint pivot-connecting the blade parts and having handle elements associated with the blade parts.

Abstract: A screwdriver tool has a driving body and a tool shank mounted in the driving body so it can rotate about its axis. A device for transmitting a torque from the driving body to the tool shank interrupts the torque transmission if a predefined limiting torque is exceeded. In its longitudinal area accommodated in the driving body, the tool shaft has a clutch section featuring a non-circular cross section. At least one spring element adjoins the clutch section radially on the outside. The spring element is mounted in the driving body in a non-rotatable manner with respect to the axis of the tool shank and in a radially deflectable manner against its spring force.

Abstract: The invention relates to an actuating tool for a fastener having an internal polygon arrangement, particularly a screw, with a tool head having an external polygon arrangement to fit into this internal polygon arrangement, wherein the tool head has a circumferential recess to receive a spring washer. It is provided that the width of the recess (17) is greater than the dimension of the spring washer (21) measured in the direction of the width, and the spring washer (21) is elastically supported at least in partial areas against the sidewalls (41, 43) of the recess (17).

Abstract: A mirror collimator has a larger parabolic mirror (11) and a smaller convexly shaped capture mirror (12) arranged at the concave side of the parabolic mirror and on its optical axis (27). A cut-out 15 is formed at the common focal point of the parabolic mirror (11) and of the capture mirror (12) and a photo-element (16) is arranged in the area of this cut-out (15). The capture mirror (12) is secured to the parabolic mirror (11) by at least one carrying device (17) extending alongside the cut-out (15).
