It is relatively fixed more firm.
In a transformable embodiment, push rod 12 is two, and interval is symmetricly set on the two of the second ontology 21
End.Pull rod 22 is one, and is threaded through the middle part of the second ontology 21 and the first noumenon 11, so that fixed by fixing piece 24
When the relative position of the first noumenon 11 and the second ontology 21, the first noumenon 11 and the position of the second ontology 21 will not shift.
In an application example, as shown in Figure 1-3, the course of work of the limiting device of the utility model includes:
It is by bolt 3 and mounting hole 23 that the first noumenon 11 and external device (ED) 100 is fixed first, limiting device is installed
To the restraining position of external device (ED) 100.At this point, the first noumenon 11 and the second ontology 21 are fit-state.Judge current second
The contact surface 212 of body 21 and external device (ED) 100 to whether there is gap between limiting component 101, adjusted if there is gap
Position of second ontology 21 relative to the first noumenon 11, to eliminate gap.Specifically, first by the spiral shell of pull rod 22 and the second ontology 21
Line junction is unscrewed, so that pull rod 22 is stretched out with respect to the second ontology 21, and then guarantees pull rod 22 is connect with the first noumenon 11 one
End has certain activity surplus.Then rotating push-rod 12 keep the other end of push rod 12 mobile to the joint face of the second ontology 21,
The second ontology 21 can be pushed mobile to the direction far from the first noumenon 11 after with the contact of the joint face 211 of the second ontology 21, directly
Contact surface 212 to the second ontology 21 is contacted with to limiting component 101, so that gap disappears, treats limiting component to realize
101 accurate limiting.
When do not need to treat limiting component 101 limited when, first by the threaded connection place of push rod 12 and the first noumenon 11
Unscrew, so that the other end of push rod 12 is not contacted with the joint face 211 of the second ontology 21, even if the other end of push rod 12 and second
Certain gap is reserved between ontology 21, then rotating tension bar 22 so that the other end of pull rod 22 by with the second ontology 21
The threaded connection of junction drives the second ontology 21 to close to the movement of 11 direction of the first noumenon.
