Description

Fixing device for fixing a placement body to a placement surface of a placement device Technical Field The present invention relates to a fixing device for fixing a placement body at a placement surface of a placement device. Background Fixing devices for fixing a placement body at a placement surface of a placement device are known from the prior art in different configurations. In the case of these fastening devices, the fastening device is fastened at the placement surface of the placement device and the clamping element of the fastening device is arranged above the placement body and is screwed on continuously by means of a tool until the placement body to be clamped is clamped at the placement surface by the fastening device. Depending on the accessibility of the position of the clamping element of the fastening device, which is to clamp the placement body, the tool for tightening the clamping element has difficulty reaching the clamping element and the tightening of the clamping element by the tool proves inconvenient. When the clamping element has been fixed at the fixing device, the arrangement of the fixing device at the placement surface can prove difficult if the geometry of the placement body to be fixed makes accessibility of the placement surface difficult. Disclosure of Invention An object of an embodiment of the invention is to propose a fixation device for a fixation means for fixing a placement body at a placement face of a placement device, in which the arrangement of placement bodies at the placement face and the fixation of placement bodies by the fixation device is improved. The object is achieved by a fastening device for fastening a placement body at a placement surface of a placement device, having at least one base which can be fastened indirectly or directly at the placement surface of the placement device, having at least one housing which encloses the base or which is fastened at the base, having at least one clamping element which is arranged outside the housing on a side of the housing facing away from the base and is movable relative to the housing, and having at least one adjusting unit which comprises at least one adjusting element, at which the clamping element is rotationally fixed relative to the adjusting element and is fixed in a position-fixed manner, and which comprises at least one adjusting drive by means of which the adjusting element and the clamping element fastened thereto can be transferred from a release position into a pre-clamping position by means of a rotation about a rotation axis extending transversely to the placement surface, in which the adjusting element and the clamping element are twisted about the release position relative to the rotation axis and are fastened against further rotation about the rotation axis, and in which the adjusting element and the clamping element are movable in a translational direction relative to the clamping element from the pre-clamping position in a translation direction parallel to the rotation axis of the housing by means of the pre-clamping position into the clamping position. By the fastening device comprising an adjusting unit in which the adjusting element and the adjusting drive co-act in such a way that the adjusting element and the clamping element fastened thereto can be transferred from a release position by rotation about a rotation axis extending transversely to the placement surface into a pre-clamping position, from which the clamping element can already be preassembled at the fastening device and by the adjusting drive transferred from the release position into a pre-clamping position, in which the clamping element releases the placement of the placement body at the placement surface without collision, and in which the clamping element is positioned above the placement body for clamping and fixing. By means of the adjustment drive of the clamping element, the placement body can be transferred from the pre-clamping position into the clamping position by a translational movement in the direction of the housing parallel to the axis of rotation, and the placement body can be clamped in a simple manner. By adjusting the setting of the drive, it is not absolutely necessary that the clamping element is directly accessible by the tool. The adjustment drive can be arranged at a position of the fastening device which is always collision-free and accessible in a simple manner by a tool or an operator. In the clamping position, the distance between the clamping element and the placement surface is reduced relative to the pre-clamping position, which means that the clamping element is moved by its arrangement in the pre-clamping position in the direction of the placement surface in order to reach the clamping position. In the case of an embodiment of the fastening device, it has proven to be advantageous if the displacement of the adjusting element from the release position into the pre-clamping position, in addition
