Anti-rotation device 70 stops: pivoting member 20 relative to clamping support element 10 maximum angle position location and therefore preliminary election inadvertently adjusted. Anti-rotation device 70 acts on baffle plate 50 at this, thus for adjusting angle preselection mechanism 40, need to be applied certain power effect or certain torque by unshowned user, in order to regulate the position of baffle plate 50 and therefore angle preselection mechanism 40 in order to preliminary election pivoting member 20 relative to the maximum angle position clamping support element 10.

As, shown in Fig. 7,14,17,21 and 22, anti-rotation device 70 is by polygon surface 52, described eight elongated holes 53 on the through hole 51 of the elastically deformable on baffle plate 50 and is designed by corresponding polygon surface 31 on the fulcrum post 30 of pivoting member 20. For the function of anti-rotation device 70, the fulcrum post 30 of pivoting member 20 is positioned in the through hole 51 of elastically deformable, sees Fig. 8. Polygon surface 31 on fulcrum post 30 and the polygon surface on the through hole 51 of elastically deformable 52 are therefore opposed, thus the two polygon surface 31,52 works as only locking face, and the position adjustment of angle preselection mechanism 40 only just can realize with certain power effect or certain moment. By eight elongated holes 53 it is achieved that, certain elastic material such deformable ground between eight elongated holes 53 and through hole 51 that has of baffle plate 50 designs so that the lobe of the only locking face on through hole 51 can relative to the lobe 32 radial and outward deformation (nachgeben) of the only locking face on fulcrum post 30. Alternatively it can be possible that by relative to the spring of through hole 51 radially location or above-mentioned easily and unexpectedly the adjusting of baffle plate 50 can be avoided relative to the ball-spring arrangement of through hole 51 radially location.

Particularly, as shown in Figure 16 and 17, the polygon surface 52 on the through hole 51 of elastically deformable is designed as the integrated ingredient of baffle plate 50. According to a kind of unshowned alternative embodiment it can be stated that anti-rotation device 70 as independent component by the material forming of elastically deformable, this material navigates in the breach of baffle plate 50. Baffle plate 50 thus can by making the material of less elastic deformation.

Fixing device 80 is for stoping moving axially or unclamping of angle preselection mechanism 40, and this angle preselection mechanism self comprises baffle plate 50, anti-rotation device 70 and display device 90.

Display device 90 is for showing for the pivoting member 20 angle relative to the corresponding preliminary election of the maximum angle position of clamping support element 10.

This semicircular dish 91 comprise at this front side 91a, rear side 91b, on seamed edge 91c, lower seamed edge 91d and through hole 92. Seamed edge 91c is provided with the first breach 93 of the form of the seamed edge of decline, in order to be not semicircular dish 91 but the first stop element 56 gear of baffle plate 50 comes on the prevention element 14 of clamping support element 10 on described, sees Fig. 4 and 18.

Lower seamed edge 91d is provided with the second breach 94, this second breach observation window of the maximum angles acted among three angles (that is 22.5 ��, 45 �� or 50 ��), described angle is used for the pivoting member 20 maximum angle position relative to clamping support element 10.

Through hole 92 has the polygon surface 95 including a number of equally spaced from each other and axially extended lobe 96, and this polygon surface is corresponding with the polygon surface 31 of fulcrum post 30. This same main composition of polygon surface 95 of through hole 92 stops locking face. Semicircular dish 91 display device 90 relatively rotating relative to fulcrum post 30 in other words can be stoped by the polygon surface 95 of through hole 92 and the polygon surface 31 of fulcrum post 30 because the only locking face of semi-circular disks 91 and fulcrum post 30 only locking face accordingly and lobe 32,96 opposing directed relative to each other rotate.

Fixing device 80 is designed by the holding element 97 positioned around through hole 92 on the rear side 91b of semi-circular disks 91. Holding element 97 is the form of four card locking bars 98 equally spaced from each other. Described card locking bar 98 comprises first end 98a and the second end 98b respectively. By described first end 98a, card locking bar 98 is fixed on the rear side 91b of semi-circular disks 91. The second end 98b of each card locking bar 98 points to along through hole 92 direction respectively. Holding element 97 has semi-circular disks 91 is maintained at the function on fulcrum post 30. For this, the second end 98b of each card locking bar 98 be respectively protruding into the annular ring of fulcrum post 30 around groove 33 in. Card locking bar 98 has certain elastic force for this, this elastic force radially press fulcrum post 30 groove 33 on and with this stop card locking bar 98 from groove 33 again out. Therefore, display device 90 moving axially from fulcrum post 30 is stoped by the mating reaction of card locking bar 98 and groove 33.

In a kind of alternative design, holding element 97 can also realize by the form of unshowned hole-cotter pin arrangement, the retaining ring of self-locking, clamping connector or the like.

Pivoting member 20 is pivotably fastened on the circular open 18 of clamping support element 10 by the first tightening member 22. The fulcrum post 30 of pivoting member 20 extends through the first elongated hole of the arc of clamping support element 10, and unshowned retaining element extends through the second elongated hole 17 of the arc clamping support element 10.

The through hole 51 of baffle plate 50 is positioned on fulcrum post 30, thus baffle plate 50 can expend rotation around fulcrum post 30 with certain power. Fixing device 80 is positioned on fulcrum post 30 and is positioned at (that is on it) above baffle plate 50 for fixed stop plate 50. For this, the through hole 51 of semi-circular disks 91 positions around fulcrum post 30. When baffle plate 50 in order to preliminary election pivoting member 20 is adjusted to three predetermined angle values (that is 22.5 ��, 45 �� or 50 ��) for the moment relative to the maximum angle position of clamping support element 10 by rotational stop plate 50, by semi-circular disks 91 through hole 92 and fulcrum post 30 and the polygon surface 95 relative to each other of holding element 97 in the groove 33 of fulcrum post 30, display device 90 keeps fixing. The breach 94 of display device 90 is used for exposing only selected angle value.

As shown in Figure 18, baffle plate 50 so rotates to be adjusted to angle value 50 �� so that the first stop element 56 is in backstop to the permission pivoting member maximum range of pivot relative to 50 �� of clamping support element 10 when stoping on element 14.

Figure 21 illustrates the second design of baffle plate 150, and this second design is roughly the same with the first design of baffle plate 50. But unlike that the first design part of baffle plate 50 is in that, the second design of baffle plate 150 comprises the groove 200 of arc, and the slot part ground of this arc extends around polygonal through hole 151. The groove 200 of arc comprises first end 200a and the second end 200b.

Figure 22 illustrates the second design of pivoting member 120, and this second design is substantially roughly the same with the first design of pivoting member 20. But it is different in that with the first design of pivoting member 20, the restriction element 220 of form of the lobe 222 extended with wedge shape that the second design of pivoting member 120 is included on first surface 121c. Wedge shape lobe 222 comprises the pin element 223 of cylindricality, and this pin element has first end 223a and the second end 223b. The lobe 222 that the first end 223a of pin element 223 extends with described wedge shape is connected. Pin element 223 is perpendicular to the 3rd surface 121e and extends and be parallel to fulcrum post 30 at this and extend. As shown in Figure 23 and 24, the second end 223b of pin element 223 with the confined state of pivoting member 120 and baffle plate 150 under guide in the groove 200 of the arc of baffle plate 150. Baffle plate 150 is limited by the pin element 223 limited guiding in the groove 200 of arc relative to moving pivotally of pivoting member 120, because pin element 223 only can move from the first end 200a of groove 200 to the second end 200b of groove 200. As described above, pivoting member 120 is connected with clamping support element 10. Therefore, by the pin element 223 limited guiding in the groove 200 of arc, baffle plate 50 is all limited relative to the pivoting action of pivoting member 120 and clamping support element 10. As figure 23 illustrates, baffle plate 150 so rotates according to the second design, make to be adjusted to angle value 50 ��, that is the first stop element 156 is in backstop to the permission pivoting member 120 maximum range of pivot relative to 50 �� of clamping support element 10 when stoping on element 14. According to the adjustment of the baffle plate 150 of the second design therefore corresponding in figure 18 according to the adjustment of the baffle plate 50 of the first design in Figure 23 and 24.

Figure 25 illustrates the 3rd design of baffle plate 350, and the 3rd design is roughly the same with the first design of baffle plate 50. Being different in that with the first design of baffle plate 50, the 3rd design of baffle plate 350 comprises the restriction element 362 of the form of pin, and this pin has first end 362a and the second end 362b. The first end 362a of the pin 362 being designed as restriction element is positioned on the rear side 350d of baffle plate 350. Pin 362 is perpendicular to the rear side 350d of baffle plate 350 with the second end 362b freely and is parallel to the extension of fulcrum post 30 ground at this.

The second end 362b of baffle plate 350 is used as backstop originally. Baffle plate 350 moving pivotally by the backstop on the second end 362b of pin 362 the first position 341 on the second surface 21d of pivoting member 20 and being limited by the backstop on the pin 362 second position 342 on the second surface 21d of pivoting member 20 relative to pivoting member 20. As described above, pivoting member 20 is connected with clamping support element 10. By restricting the baffle plate 350 pivoting action relative to pivoting member 20, therefore also limit stop plate 350 relative to the pivoting action of clamping support element 10. As figure 25 illustrates, baffle plate 350 so rotates according to the 3rd design, make to be adjusted to angle value 50 ��, that is the first stop element 356 is in backstop to the permission pivoting member 20 maximum range of pivot relative to 50 �� of clamping support element 10 when stoping on element 14. In fig. 25 according to the adjustment of the baffle plate 350 of the second design therefore corresponding in figure 18 according to the adjustment of the baffle plate 50 of the first design.
