Description

Technical Field

[0001] The present invention relates to a fixing device for fixing a placement body to the placement surface of a placement device. Background Technology

[0002] Fixing devices for securing a placement object to the placement surface of a placement device are known in the prior art in various structural forms. In these fixing devices, the fixing device is fixed to the placement surface of the placement device, and the clamping element of the fixing device is arranged above the placement object and is continuously tightened by means of a tool until the placement object to be clamped is clamped to the placement surface by the fixing device.

[0003] Based on the accessibility of the clamping element of the fixing device that should clamp the object, the tool used to tighten the clamping element is difficult to reach the clamping element, and the clamping element is inconvenient to tighten by the tool.

[0004] When the clamping element is fixed at the fixing device, if the geometry of the object to be fixed makes the accessibility of the placement surface difficult, then the arrangement of the fixing device at the placement surface can be proven to be difficult. Summary of the Invention

[0005] An embodiment of the present invention aims to provide a fixing device for fixing a placement body to a placement surface of a placement device, wherein the arrangement of the placement body on the placement surface and the fixing of the placement body by the fixing device are improved.

[0006] This objective is achieved by a fixing device for securing a placement body to the placement surface of a placement device, comprising at least one base which can be indirectly or directly fixed to the placement surface of the placement device, at least one housing surrounding or fixed to the base, at least one clamping element disposed outside the housing on the side of the housing opposite to the base and movable relative to the housing, and at least one adjusting unit comprising at least one adjusting element, the clamping element being torsionally and positionally fixed relative to the adjusting element, and comprising at least one adjusting actuator, wherein the adjusting element and the clamping element fixed thereto can be transferred from a release position to a pre-clamping position by rotation about a rotation axis extending transversely to the placement surface, in which the adjusting element and the clamping element are torsionally and fixed about the rotation axis relative to the release position to prevent further rotation about the rotation axis, and the adjusting element and the clamping element can be transferred from the pre-clamping position to a clamping position by translational movement in a direction parallel to the rotation axis in the housing by the adjusting actuator, in which the distance between the clamping element and the placement surface is reduced relative to the pre-clamping position.

[0007] By including an adjustment unit in the fixing device, in which the adjustment element and the adjustment drive work together such that the adjustment element and the clamping element fixed therein can be moved from the release position to the pre-clamping position by rotation about a rotation axis extending transversely to the placement surface, the clamping element may have been pre-assembled at the fixing device and moved from the release position to the pre-clamping position by the adjustment drive, in which the clamping element releases the placement of the body at the placement surface without impact, and in which the clamping element is positioned above the placement body for clamping and fixing the placement body.

[0008] The object can be easily clamped by the adjustment drive of the clamping element, which moves it from the pre-clamping position to the clamping position through a translational movement parallel to the axis of rotation in the direction of the housing.

[0009] By adjusting the actuator settings, which is not strictly necessary, the clamping element can be directly accessed by the tool. The actuator can be positioned in a location on the fixed equipment that is always free from impact and easily accessible to the tool or operator.

[0010] 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 in the direction of the placement surface by its arrangement in the pre-clamping position in order to reach the clamping position.

[0011] In the case of a fixed device, it has proven advantageous when the transfer of the adjusting element from the release position to the pre-clamping position includes translational movement in the direction parallel to the rotation axis in addition to rotation about the rotation axis, and / or when the clamping element is arranged flush with the placement body in the direction parallel to the rotation axis in the pre-clamping position.

[0012] When the adjustment element is transferred from the release position to the pre-clamping position, in addition to rotation about the axis of rotation, it includes translational movement in the direction parallel to the axis of rotation in the housing, the distance between the adjustment element and the placement surface can be reduced in the case of transferring the adjustment element from the release position to the pre-clamping position.

[0013] When the clamping element is arranged flush with the object in the pre-clamping position in a direction parallel to the axis of rotation, the transfer from the pre-clamping position to the clamping position can only be achieved through a translational motion extending parallel to the axis of rotation. This results in a simplified kinematic process in the transfer from the pre-clamping position to the clamping position.

[0014] To facilitate the simple guidance and retention of the adjusting element during transitions from the release position to the pre-clamping position and from the pre-clamping position to the clamping position, it has proven advantageous when the housing includes a housing cavity in which the adjusting element is at least partially arranged, and the adjusting element rests planarly against an inner surface portion of the housing that is rotationally symmetrical about the rotation axis, wherein the adjusting element is rotatable about the rotation axis and movable relative to the housing parallel to the rotation axis.

[0015] In one improved embodiment of the last mentioned form, the fixing device may be configured such that it includes at least one guide unit comprising at least one grooved receiving portion in an inner surface section of the housing, at least one guide groove formed by a recess in an outer surface section of the adjusting element, and at least one guide bolt engaged in the receiving portion and the guide groove.

[0016] By providing a guide unit, the transfer from the release position to the pre-clamp position and from the pre-clamp position to the clamp position can be provided mechanically and simply through structural characteristics and shape as a kinematic process.

[0017] The guide unit can be constructed arbitrarily in principle, as long as it is intended for the kinematic process of moving from the release position to the pre-clamping position and from the pre-clamping position to the clamping position. This can be easily ensured in such a way that, when the guide groove includes a first guide section, it extends transversely or obliquely to the axis of rotation, particularly parallel to the axis of rotation in the direction of the clamping element, and its intended adjustment element moves from the release position to the pre-clamping position; and when the guide groove includes a second guide section, the first guide section passes into the second guide section and extends parallel or obliquely to the axis of rotation, preventing further rotation about the axis of rotation, and its intended adjustment element moves from the pre-clamping position to the clamping position.

[0018] The first guide section of the guide groove may include a beak-shaped extended cross section. This cross section extends substantially parallel to the placement surface on a boundary extending in the direction of the placement surface and extends in the direction of the clamping element on the side of the first guide section opposite to the placement surface. By extending the second guide section parallel or inclined to the axis of rotation, further torsion of the clamping element about the axis of rotation is prevented by the second guide section, and only movement parallel to the axis of rotation is allowed. Thus, the transfer from the release position to the pre-clamping position and from the pre-clamping position is mechanically and simply guided.

[0019] To connect the adjusting actuator indirectly to the clamping element in a simple manner, it has proven advantageous when the adjusting unit includes at least one rod-shaped or bar-shaped transmission element, which is at least partially arranged in the housing, is torsionally connected to the adjusting element, and has a transmission region including an externally threaded section that operates about a rotation axis. This externally threaded section is arranged on the side of the transmission element opposite to the clamping element, and through it, the adjusting element is movable at least parallel to the rotation axis during operation of the adjusting actuator for transition from the release position to the pre-clamping position and / or from the pre-clamping position to the clamping position.

[0020] By connecting the transmission element to the adjustment element in a torsion-resistant manner and connecting it to the adjustment driver via the transmission area, the adjustment element of the adjustment unit can be connected to the adjustment driver in a simple manner.

[0021] The transmission element, with its transmission area including the external thread section, works in conjunction with the adjusting drive. This at least makes it possible for the transmission element to move parallel to the axis of rotation.

[0022] In an improved embodiment mentioned last, the transmission element, during the transfer of the adjusting element and the clamping element fixed thereto from the release position to the pre-clamping position, can be moved not only parallel to the rotation axis but also rotate about the rotation axis via the adjusting drive. Upon reaching the pre-clamping position, further rotational movement of the adjusting element and the transmission element, which is torsionally connected to the adjusting element, is then prevented by the guide unit. Thus, the adjusting element, during the transfer from the pre-clamping position to the clamping position, is fixed to prevent further torsion and performs only a translational movement in the direction of the placement surface, parallel to the rotation axis.

[0023] The adjusting drive can be constructed arbitrarily in principle, as long as it functions in conjunction with the transmission area of ​​the transmission element for adjusting the adjusting element. The fixed device can be operated in a simple manner when the adjusting drive includes at least one worm gear transmission having at least one rod-shaped worm element rotatably driven about a worm axis extending transversely or obliquely to the axis of rotation, the worm element including an externally threaded section in the transmission area, and having at least one worm wheel whose externally threaded section engages with the externally threaded section of the worm element, and particularly with the internally threaded section engaging with the externally threaded section of the transmission element of the adjusting unit; and / or when the adjusting drive includes at least one actuating element including a receiving portion, the actuating element being externally actuated and the worm element rotatable about the worm axis during operation via the actuating element.

[0024] By incorporating a worm gear drive into the adjustment actuator, the operating element can be easily positioned at any location on the fixed device, allowing for external manipulation via tools and / or by an operator. Thus, accessibility of the clamping element is not required during transitions from the release position to the pre-clamping position and from the pre-clamping position to the clamping position.

[0025] To ensure the relative motion of the transmission element with respect to the worm gear drive and thereby perform the previously described kinematic process, it has proven advantageous when the worm gear drive, especially the worm element and worm wheel, and / or when the actuating element is arranged in a housing and fixed to prevent translational movements parallel to and transverse to the axis of rotation.

[0026] This ensures that, during the operation of the worm gear drive, the transmission element moves relative to the housing within the housing, while the worm gear drive and the operating element are fixed in approximately a fixed position.

[0027] The following implementations of the fixed equipment are possible, in which the transmission element and the regulating element constitute a common one-piece component, or in which the transmission element and the regulating element comprise two separate or separable components that are torsionally connected to each other about the axis of rotation.

[0028] When the transmission element and the adjusting element constitute a single, one-piece component, the construction of the fixing device can reduce the number of components. In this case, the transmission area is constructed on the side facing the placement surface of the adjusting element. When the transmission element and the adjusting element comprise two separate or separable components, additional functions of the fixing device can be achieved. When the transmission element and the adjusting element comprise two separate or separable components, it has proven advantageous that the adjusting unit includes at least one anti-torsion device by which the transmission element is fixed against torsion about the axis of rotation.

[0029] The anti-torsion device ensures that the transmission element is moved almost parallel to the axis of rotation and fixed to prevent rotational movement when driven by the adjusting driver.

[0030] The anti-torsion device can be installed at any location on the fixed equipment. In one embodiment, the anti-torsion device includes at least one continuous gap in the adjusting element extending transversely to the axis of rotation, at least one single-sided open gap extending transversely to the axis of rotation, at least one continuous hole in the transmission element extending transversely to the axis of rotation, and at least one pin-shaped plug element that passes transversely to the axis of rotation through at least one gap in the adjusting element and at least one hole in the transmission element, and the plug element particularly includes a cross-section that is constructed corresponding to, and particularly complementary to, the cross-section of at least one gap in the adjusting element, and extends transversely to the axis of rotation of the hole in the transmission element.

[0031] Thus, the transmission element and the adjustment element can be connected to each other in a simple manner. In the case where the transmission element is torsionalally fixed at the adjustment element, it is first positioned such that it is flush with at least one continuous gap and one continuous hole in the transverse direction of rotation. In this case, the plug element is then inserted not only through at least one gap but also through the continuous holes in the transmission element.

[0032] A one-sided open gap extending transversely to the axis of rotation is also accessible from the direction of the cavity and / or opening.

[0033] In one embodiment of the fixed device, a pin-shaped plug element extends fully through the clamping element and the transmission element in a plane transverse to the axis of rotation in an engaged arrangement.

[0034] By making the pin-shaped embolic element include a cross-section configured to correspond to, and in particular complement to, at least one gap of the adjusting element, the relative movement of the embolic element within the gap of the adjusting element is prevented or at least severely restricted. The pin-shaped embolic element may include a rounded, in particular circular or polygonal, in particular 4, 6 or 8-sided cross-section.

[0035] As previously described, the anti-torsion device can be located at any position on the fixed device. In a supplementary or alternative embodiment, the anti-torsion device includes at least one groove extending parallel to the axis of rotation in the housing, particularly in the lower housing member, arranged about the side opposite to the adjusting element with respect to the adjusting actuator, and the anti-torsion device includes at least one pin-shaped plug element that can be detachably or indetachably fixed or secured to the free end of the transmission element opposite to the adjusting element, extending laterally beyond the transmission element and engaging at least one end into at least one of the at least one groove.

[0036] The slot is positioned relative to the adjusting actuator on the side of the housing facing the base. The same applies to the plug element, which is positioned on the side of the transmission element facing the base. The plug element may have a cross-section transverse to the axis of rotation, corresponding to, and particularly complementary to, the cross-sectional configuration of the slot. Through the engagement of the plug element into the slot, the transmission element is held against rotation about the axis of rotation, but is released for movement parallel to the axis of rotation.

[0037] It is possible for an embodiment in which two slots are provided in the housing, which are positioned opposite each other about the axis of rotation, wherein the plug element extends transversely to the axis of rotation on both sides beyond the transmission element and engages at each end into one of the slots.

[0038] The fixing device may include at least one stop within the housing, which, in the case of reaching the clamping position, restricts the movement of the clamping element parallel to the axis of rotation in the direction of the placement surface, wherein, in the clamping position, the adjusting element, the transmission element, and / or the clamping element abuts against at least one of the at least one stop. Furthermore, the fixing device may include at least one tensioning element that acts between the transmission element and the adjusting element and tensions the clamping element fixed to the adjusting element in the direction of the housing parallel to the axis of rotation.

[0039] When the fixing device includes at least one stop, the stop can restrict the transfer from the pre-clamped position to the clamped position. When a tensioning element is provided between the adjusting element and the transmission element, such that the clamping element fixed at the adjusting element is tensioned parallel to the axis of rotation in the direction of the housing, the force acting on the object to be clamped acts less rigidly. In this case, it becomes possible to slightly move the object by overcoming the tensioning force of the tensioning element.

[0040] To allow relative movement parallel to the axis of rotation between the adjusting element and the transmission element, which are fixed to each other against torsion, it has proven advantageous when the continuous bore in the transmission element transverse to the axis of rotation includes an elongated bore extending parallel to the axis of rotation, through which the transmission element, parallel to the axis of rotation, is positioned between a first stop and a second stop relative to a pin-shaped plug element. In the first stop position, the adjusting element has a first distance relative to the placement surface via a tensioning element, and in the second stop position, the adjusting element has a second distance relative to the placement surface greater than the first distance via movement against the tensioning force of the tensioning element.

[0041] The fixing device can be compactly constructed such that when the adjusting element of the adjusting unit includes a cavity that is accessible at least from the base direction via an opening, a rod-shaped or bar-shaped transmission element is at least partially arranged in the cavity of the adjusting element.

[0042] In this case, the rod-shaped or bar-shaped transmission element can be arranged at least partially within the regulating element.

[0043] In one improved embodiment mentioned last, it is advantageous that when the adjusting element includes at least one connecting section arranged on the side of the adjusting element opposite to the clamping element, it includes an opening to the cavity of the adjusting element and has an inner diameter about the axis of rotation smaller than the inner diameter of the cavity, in particular, wherein the connecting section of the adjusting element includes a transverse gap continuous to the axis of rotation at least on one side, and particularly on both sides about the axis of rotation, an anti-torsion device.

[0044] Finally, it is advantageous when the adjusting unit includes at least one support element arranged in the cavity of the adjusting unit, the support element being fixed at the end of the transmission element opposite to the adjusting drive and having an outer diameter corresponding to, and particularly complementary to, the inner diameter of the cavity, transverse to the axis of rotation, and when the tensioning element of the adjusting unit is arranged in the cavity of the adjusting element, passing through the transmission element parallel to the axis of rotation, and abutting against not only the connecting section of the adjusting element but also at the support element.

[0045] Viewed transversely to the axis of rotation, the tensioning element has a diameter larger than that of the connecting section including the opening of the adjusting element. Thus, the tensioning element is in contact support not only at the connecting section of the adjusting element but also at the support element fixed to the transmission element. In the case of relative movement between the adjusting element and the transmission element, the distance between the connecting section and the support element is reduced, thereby compressing the tensioning element. In this case of relative movement, the pin-shaped plug element moves from a first stop position in the elongated hole to a second stop position. Attached Figure Description

Detailed Implementation

[0048] These figures show two embodiments of a fixing device, generally indicated by reference numeral 2, for securing the object to the placement surface 4 of the placement device. Each fixing device 2 includes a base 6, which is indirectly or directly fixed to the placement surface 4 of the placement device.

[0049] Furthermore, the fixing device 2 includes a housing 8, which is fixed to the base 6. In the embodiment of the fixing device 2 shown in the figures, the housing 8 includes a lower housing member 10 fixed to the base 6 and an upper housing member 12 fixed to the lower housing member 10.

[0050] In addition, the fixing device 2 includes a clamping element 14, which is arranged outside the housing 8 on the side of the housing 8 opposite to the base 6 and is movable relative to the housing 8.

[0051] Furthermore, the fixing device 2 includes an adjustment unit 16, which includes an adjustment element 18, a clamping element 14 being torsionally and positionally fixed relative to the adjustment element 18 at the adjustment element, and includes at least one adjustment actuator 20, through which the adjustment element 18 and the clamping element 14 fixed thereat can be released from a position ( Figure 1 The adjusting element 18 and the clamping element 14 are moved to a pre-clamping position (Fig. 2) by rotation about a rotation axis 22 extending transversely to the placement surface 4. In this pre-clamping position, the adjusting element 18 and the clamping element 14 are twisted relative to the rotation axis 22 about the release position and fixed to prevent further rotation about the rotation axis 22. The adjusting element 18 and the clamping element 14 are moved from the pre-clamping position by the adjusting actuator. Figure 2 It can be transferred to the clamping position by translational movement in the direction of the housing 8 parallel to the rotation axis 22. Figure 3 In the clamping position, the distance between the clamping element 14 and the placement surface 4 is reduced relative to the pre-clamping position.

[0052] In the embodiment of the fixed device 2 shown in the figure, the housing 8 includes a housing cavity 24 in which an adjustment element 18 is arranged at least partially, and the adjustment element 18 is planarly attached to an inner surface portion of the housing 8 that is rotationally symmetrical about the rotation axis 22 on an outer surface portion of the housing 8, wherein the adjustment element 18 is rotatable about the rotation axis 22 and movable relative to the housing 8 parallel to the rotation axis 22.

[0053] To move the adjusting element 18 and the clamping element 14 fixed thereon from the released position to the clamped position, a guide unit 26 is formed in the housing 8 and at the adjusting element 18. The guide unit includes a groove-shaped receiving portion 28 in the inner surface section of the housing 8, a groove 30 in the outer surface section of the adjusting element 18, and a guide bolt 32 that engages with the receiving portion 28 and the guide groove 30 including the groove.

[0054] In the embodiment shown in the figure, the guide groove 30 including the receiving portion 28 is formed by a first guide section 34 that extends transversely to the rotation axis 22 and extends in the direction of the clamping element 14 in particular parallel to the rotation axis 22, and whose predetermined adjustment element 18 is transferred from the release position to the pre-clamping position.

[0055] Furthermore, the guide groove 30, which is formed by the groove, includes a second guide section 36 into which the first guide section 34 passes and extends parallel to or inclined to the axis of rotation 22, preventing further rotation about the axis of rotation 22 and the transfer of its predetermined adjustment element 18 from the pre-clamping position to the clamping position.

[0056] exist Figures 1 to 5 The image shows an embodiment of the fixing device 2, in which the adjusting unit 16 includes a rod-shaped or bar-shaped transmission element 38. The transmission element 38 is at least partially disposed within the housing 8. The transmission element 38 and the adjusting element 18 are torsionally connected to each other via an anti-torsion device 40.

[0057] The anti-torsion device 40 includes at least one groove 74 extending parallel to the axis of rotation in the housing 8, particularly in the lower housing member 10, the groove being arranged on the side opposite to the adjusting element 18 with respect to the adjusting actuator 20, and the anti-torsion device includes at least one pin-shaped plug element 46 which can be detachably or indetachably fixed or secured to the free end of the transmission element 38 opposite to the adjusting element 18, extending transversely to the side of the axis of rotation 22 beyond the transmission element 38 and engaging at least one end in at least one of the grooves 74.

[0058] According to Figures 1 to 5In the case of the first embodiment of the fixing device, the slot 74 is arranged on the side of the housing 8 facing the base 6 relative to the adjustment drive 20. The same applies to the plug element 46, which is arranged on the side of the transmission element 38 facing the base 6.

[0059] The plug element 46, transverse to the axis of rotation 22, includes a cross-section corresponding to, and particularly complementary to, the cross-sectional configuration of the groove 74. Through the engagement of the plug element 46 into the groove 74, the transmission element 38 is held against rotation about the axis of rotation 22, but is released for movement parallel to the axis of rotation 22.

[0060] exist Figures 1 to 5 In the embodiment that can be seen, two slots 74 are provided in the housing 8, which are arranged opposite to each other about the axis of rotation 22, wherein the plug element 46 extends beyond the transmission element 38 on both sides transverse to the axis of rotation 22 and engages at each end into one of the slots 74.

[0061] Furthermore, the transmission element 38 includes a transmission region 58 on its side facing away from the support element 56, which includes an externally threaded section. The transmission region 58 can be controlled by the adjustment actuator 20, thereby allowing the transmission element 38 to rotate not only about the rotation axis 22 but also to translate parallel to the rotation axis 22 in the direction of the placement surface 4 in order to move from the release position to the pre-clamping position while the adjustment actuator 20 is in operation. Upon reaching the pre-clamping position, the transmission element 38 can be moved in the direction of the placement surface 4 by a pure translational movement parallel to the rotation axis 22 via the adjustment actuator 20. This results in the transmission element 38 being torsionally connected to the clamping element 14, and the clamping element 14 being fixed in the pre-clamping position by the guide unit 26 to prevent further torsion about the rotation axis 22.

[0062] In the case of the embodiments shown in the accompanying drawings, especially in Figures 1 to 3 as well as Figure 5 As is evident from the following, the adjusting drive 20 includes a worm gear transmission 60, which includes at least one rod-shaped worm element 62, which is rotatably driven about a worm axis 64 extending transversely or obliquely to the rotation axis 22 and includes an externally threaded section in the transmission region 66 and has at least one worm wheel 68, the externally threaded section of which is engaged with the externally threaded section of the worm element 62, and the internally threaded section of which is engaged with the externally threaded section of the transmission element 36 of the adjusting unit 16.

[0063] In addition, the adjustment drive 20 includes an actuating element 72 including a housing 70, which is externally operable and the worm element 62 is rotatable about the worm axis 64 in the case of actuation.

[0064] Figure 6 A detailed view of a second embodiment of the fixing device 2 is shown, in which the adjusting unit 16 includes a rod-shaped or bar-shaped transmission element 38. The transmission element 38 is at least partially disposed within the housing 8. The transmission element 38 and the adjusting element 18 are torsionally connected to each other via an anti-torsion device 40.

[0065] The anti-torsion device 40 includes a continuous gap 42 extending transversely to the rotation axis 22 in the adjusting element 18, a one-sided open gap 43 in the adjusting element 18, a continuous hole 44 extending transversely to the rotation axis 22 in the transmission element 38, and a pin-shaped plug element 46 that passes through both the gap 42 and the hole 44.

[0066] In the embodiment of the fixing device 2 shown in the accompanying drawings, the anti-torsion device 40 is arranged in the connecting section 48 of the adjusting element 18. An opening 50 is provided in the connecting section 48, through which the cavity 52 of the adjusting element 18 can be accessed from the outside. A tensioning element 54 is arranged in the cavity 52, one side of which is located at the connecting section 48 of the adjusting element 18. A support element 56 of the adjusting unit 16 is provided on the side opposite to the connecting section 48, and is fixed at the transmission element 38 to the side opposite to the adjusting drive 20.

[0067] The hole 44 in the transmission element 38 includes an elongated hole in which the pin-shaped plug element 46 is correspondingly arranged in a first stop position in the embodiment shown in the figures. In the first stop position, the adjusting element 18 has a first distance relative to the placement surface 4 via the tensioning element 54. The adjusting element 18 can be moved away from the placement surface 4 in a direction parallel to the axis of rotation 22 by overcoming the tensioning force until the pin-shaped plug element 46 can be arranged in a second stop position (not shown in the figures), in which the adjusting element 18 has a second distance greater than the first distance.

[0068] The working principle of fixed equipment 2 is briefly explained below: In the case of manipulating the control element 72, for example by means of a tool or manually, the worm element 62 is rotated about a worm axis 64 extending transversely to the rotation axis 22. The worm wheel 68 is driven to rotate about the rotation axis 22 via the external threaded section of the transmission region 66 of the worm element 62. The transmission element 38, with its external threaded section in the transmission region 58 arranged in the internal threaded section of the worm wheel 68, rotates about the rotation axis 22 in this case. Here, the transmission element 38 is torsionally connected to the adjusting element 18, which is thus also rotated about the rotation axis 22 according to… Figure 1 The release position is rotated. As it rotates about the axis of rotation 22, the clamping element 14 rotates relative to the housing 8, thereby moving the guide bolt 32 along the first guide section 34 of the guide unit 26.

[0069] As of reaching the point Figure 1 At the pre-clamped position, the guide bolt 32 reaches the second guide section 36 of the guide unit 26, which secures the adjusting element 18 and the transmission element 38, which is torsionally connected to the adjusting element 18, to prevent further twisting about the rotation axis 22. From reaching the pre-clamped position... Figure 2 From the pre-clamping position, the transmission element 38 can only move parallel to the rotation axis 22 during further operation of the adjustment driver 20, thereby reducing the distance of the clamping element 14 relative to the placement surface 4. Upon reaching the position according to... Figure 3 In the clamping position, the clamping element 14, the adjusting element 18 and / or the transmission element 38 abut against the stop of the housing 8, which restricts further movement in the direction parallel to the rotation axis 22 on the placement surface 4.

[0070] In order to slightly loosen the clamping element 14 to allow for movement and orientation of the placement body, the adjusting element 18 can be moved in the direction away from the placement surface 4 against the working tension of the tensioning element 54, wherein the pin-shaped plug element 46 is moved relative to the transmission element 38 within the elongated hole 44.
