Abstract
The invention relates to a screwing device (1) with two tools (2, 3) for producing or releasing a screw connection between two fastening elements (10, 11). For a simple and compact structure of the screwing device (1), the invention provides that the tools (2, 3) are during the operation of the screwing device (1) connected to one another for rotation about common rotation axes (D1, D2).
Claims10
A screwing device comprising
- at least two tools, each having a receptacle for a screwable fastening element,
- wherein during operation of the screwing device each receptacle is arranged with mutually aligned axes of rotation and spaced apart along the mutually aligned axes of rotation,
- wherein the at least two tools are connected to one another during the operation of the screwing device for rotation about the mutually aligned axes of rotation, further comprising a gear which rotatably connects the at least two tools to one another,
- wherein the gear is a toothed gear, wherein a respective gear wheel of the gear is associated with each of the at least two tools.
1 more element
A screwing device comprising at least two tools, each having a receptacle for a screwable fastening element,
- wherein during operation of the screwing device each receptacle is arranged with mutually aligned axes of rotation and spaced apart along the mutually aligned axes of rotation,
- wherein the at least two tools are connected to one another during the operation of the screwing device for rotation about the mutually aligned axes of rotation, further comprising a gear which rotatably connects the at least two tools to one another,
- wherein the gear comprises a drive gear wheel and an driven gear wheel which are motion-coupled with one another, wherein the drive gear wheel is rotatably mounted on one of the at least two tools and the driven gear wheel is attached to another one of the at least two tools.
A screwing device comprising
- at least two tools, each having a receptacle for a screwable fastening element, wherein during operation of the screwing device each receptacle is arranged with mutually aligned axes of rotation and spaced apart along the mutually aligned axes of rotation,
- wherein the at least two tools are connected to one another during the operation of the screwing device for rotation about the mutually aligned axes of rotation, wherein the screwing device further comprises at least two connecting elements, which are each connectable to one of the receptacles and which, when attached on the receptacle, are held so as to be prevented from rotating about the mutually aligned axes of rotation relative to a base body of the respective tool.
