In one embodiment, annex is not connected directly with drive mechanism 8, or is not connected with fixing device 1 also,
In the embodiment, fixing device 1 can produce interlocking with holding meanss 4, wherein, in order to clamp, simply make drive mechanism
8 enter predetermined, the position state that can fix.
The position state that is predetermined, can fixing can be fixed in a different manner.For using important for fixing device 1
, the installation of fixing device 1, i.e. annex rapidly and easyly and thus can be realized in the case of without instrument as far as possible
With remove.Although therefore it is required that drive mechanism 8 automatically can not depart from from the fixed position, in order to be taken from holding meanss 4
Lower fixing device 1 remain able to less it is bothersome in the case of leave the fixed position.Most advantageously, drive mechanism 8 can
Easy manipulation by using the hand of operator, i.e. in the case of without instrument and leave the fixed position.
The locking system 16 of fixing device 1 is shown in Fig. 6 and Fig. 3 to 5, the locking system ensures predetermined, energy
Fixed position state.Locking system 16 has on operating element 2 can swingingly supported hook-shaped section 17.Hook-shaped section 17 leads to
The spring 18 as optional pretension element is crossed by pretension, so that the hook-shaped section is as shown in Figure 6 by crowded upwards.Work as drive
From position state shown in Fig. 3, (in this state, the second clamping jaw 6 is in such position to motivation structure 8：Fixing device 1 can in the position
To be hooked in holding meanss 4) to position state shown in Fig. 4 (predetermined, the position state that can fix) motion, wherein, the second clamping jaw 6
Clamped position is reached, then hook-shaped section 17 is scarfed in the lug boss 19 in fixing device 1.Therefore, drive mechanism 8 is fixed on
Predetermined, the position state that can fix and automatically it can not depart from from the position state that is predetermined, can fixing.
In operation, in order to unclamp locking system 16 it is required that being for example pressed downward hook-shaped section 17 by finger by hand,
So as to cancel interlocking with lug boss 19, thus drive mechanism 8 can move from predetermined, the position state that can fix.
It should consider to avoid being accidentally unlocked in terms of the positioning of locking system 16.Illustrated embodiment is proposed for example away from fixing device for this
The lower area of 1 user.As the safeguard measure for avoiding being accidentally unlocked, the governor motion being discussed below can be arranged so as to：
So that operator can only so touch lockable mechanism：The risk minimization of accidental manipulation.
The fixed predetermined, possibility that is replacement or adding of position state that can fix by using drive mechanism elbow
Rod principle is realized.By being correspondingly adapted to drive mechanism 8, the element of toggle link, i.e. the first section 10 and the second section 11 are constituted,
Drive mechanism 8 crosses the dead-centre motion of toggle link component to so-called mistake dead point when being moved into predetermined, the position state that can fix
Position state.In order to unclamp the fixation, it is necessary to which the dead point for making drive mechanism 8 cross drive mechanism 8 with the power consumption increased with hand is transported
It is dynamic to leave predetermined, the position state that fix, to cancel clamping of the fixing device 1 in holding meanss 4.
Alternatively or in addition to, being provided using the gravity of annex ensures the predetermined, position that can fix of drive mechanism 8
Another possibility of state.The such configuration of shown fixing device 1 so that drive mechanism 8 has the manipulation being connected with the first section 10
Element 2, the operating element has the interface for fixing fitting, is herein permanent opening 3.Therefore, it can by annex and with
The drive mechanism 8 of the annex connection carries out same type motion.In embodiment as shown here, not only the first section 10 and
And as drive mechanism 8 the operating element 2 with fixed interface housing, carry out so as to annex rotation around axle 12 respectively
Motion, with clamping and fixing device 1, wherein, when annex is moved downward, the first section 10 is also transported downwards in shown orientation
It is dynamic.Rotational motion is substituted, translational motion or aggregate motion are also possible.
Fixing device 1 it is predetermined meet as defined in orient, being used for of drive mechanism 8 reaches the predetermined, energy
The motion (as shown in the figure) of fixed position state is the motion and driving machine supported to lower swing in the orientation by annex gravity
It is same type that being used for of the operating element 2 of structure 8, which reaches the motion of position state that is predetermined, can fixing, i.e., downward rotation
Motion.Thus, predetermined, the position state that can fix is ensured by the gravity of annex.Drive mechanism 8 is from the predetermined, energy
The motion that fixed position state is left can be realized by overcoming annex gravity and lifting annex herein.
It is described herein be used to ensureing that drive mechanism 8 to be in predetermined, the position state that can fix possibility be can
Combination.
In operation, after the locking system 16 that exists when necessary is unlocked, drive mechanism 8 is by applying motoricity and root
It is swung up herein against based on the confining force for crossing dead point position state or against annex gravity according to situation, it is first from there through this motion
The second clamping jaw 6 is first set to be left from clamped position, fixing device 1 can be left from holding meanss 4 in same motion, rather than such as
Traditionally need two different motions, the i.e. release of fixing bolt and the taking-up of fixing device 1.
In order to which fixing device 1 is placed in holding meanss 4, first generally in the extension side perpendicular to holding meanss 4
Fixing device 1 is disposed into the plane of movement of (longitudinal direction of track), is suspended on herein in holding meanss 4.Then will be solid
Determine device 1 to clip in holding meanss 4 by the motion of operating element 2, wherein, operating element 2 is in order to fixing device 1 is placed in
Moved in holding meanss 4 in the plane of movement.Therefore, in order to fixing device 1 is disposed and holding meanss 4 are clamped in
On, the motion accordingly merged in the same direction is also feasible.
Fig. 7 shows the exploded view of governor motion 9.Following possibilities are produced by governor motion 9：Make to be clamped in holding meanss
Fixing device 1 on 4 is unclamped so far forth, thus for example can along the mobile fixture 1 of holding meanss 4, wherein, it is fixed
Device 1 is also fixedly held in holding meanss 4 by clamping jaw 5,6.It is possible thereby to can not be taken in fixing device 1 from holding meanss 4
Non-dangerously mobile fixture 1 in the case of lower.
Optional governor motion 9 be connected with the first section 10 of drive mechanism 8 and be connected with operating element 2 (see Fig. 8 a,
8b)。
Governor motion 9 has pin 20, and the pin swingingly can be connected by two camber members 21 with the first section 10.
Connection between the section 10 of pin 20 and first alternatively can be realized otherwise, for example, pass through plate or other suitable companies
Connection device.Pin 20 has central axis 22.On the end opposed with the first section 10, the nothing of 20 and first cylindricality block of pin 23
Do not connect axially moveably in relative rotation and on the direction of central axis 22.Governor motion 9 also has the second cylindricality
Block 24, the second cylindricality block is not connected without relative rotation and axially moveably with regulating element 7.Second cylindricality block 24
With hole, pin 20 is so inserted into the hole so that the pin can be axially moved simultaneously relative to the second cylindricality block 24
And can reverse.That is, the pin 20 being connected with the first section 10 and the regulation being connected by the second cylindricality block 24 with housing 2
Element 7 thus can axially in relation to each other be moved on the direction of the central axis 22 of pin 20 and can reversed.
First cylindricality block 23 and the second cylindricality block 24 have one respectively on end toward each other and favour central shaft
The end face of line 22.By the inclination of end face, as figures 8 a and 8 b show, produced when regulating element 7 is reversed pin 20 relative to
The axial movement of regulating element 7.
A kind of situation is shown in Fig. 8 a, in the situation, fixing device 1 works as described above.First cylindricality block
23 and second cylindricality block 24 so reverse relative to each other so that by the first cylindricality block 23 and the second cylindricality block 24 end face it is corresponding
Inclination causes the first cylindricality block 23 and the second cylindricality block 24 at utmost to leave move each other in the axial direction.Because the second cylindricality
Block 24 is connected with housing 2, thus the first cylindricality block 23 by it is described leave motion moved down herein together with pin 20.By
This, when drive mechanism 8 is in predetermined, the position state that can fix, the first section 10 is to lower swing and the second section 11
Move down, thus the second clamping jaw 6 is so swung so that the point of force application 15 on the second clamping jaw 6 is as far as possible towards the first clamping jaw 5
Motion, that is to say, that produce the maximum clamping force that can be realized.
A kind of situation is shown in figure 8b, in the situation, the second clamping jaw 6 is applied to the clamping force quilt in holding meanss 4
Cancel or reduce.This is represented by the gap between the second clamping jaw 6 and holding meanss 4 in principle.First cylindricality block 23 and
Two cylindricality blocks 24 are so rotated relative to one another by regulating element 7 so that two end faces against each other so that pin 20 is as far as possible
Move up.Therefore, the first section 10 can be swung up, and the power that thus the second section 11 is applied on the second clamping jaw 6 is taken
