When movement joint both sides agent structure is subjected to displacement change in x direction, first support 4 is with agent structure in x direction
Upper movement, because the first montant 13 is arranged in the through hole of first support 4 so that first level bar 4-1 and the first montant 13 are in x side
To there is relative movement, when first support 4 produces change in displacement and moves in x direction because of movement joint both sides agent structure, the
One montant 13 then will not move, and the displacement monitoring component being therefore arranged on the first montant 13 and the second montant 14 then will not be drawn
Stretch or shorten, thus the inaccurate problem of monitoring result of displacement monitoring component can be avoided.In the same manner, when movement joint both sides body junction
When z direction is subjected to displacement change, first support 4 moves in a z-direction structure with agent structure, because the first montant 13 is arranged on
So that first level bar 4-1 and the first montant 13 occur relative movement, in a z-direction in first support in the through hole of one support 4
4 because movement joint both sides agent structure is when z direction produces change in displacement and moves, and the first montant 13 then will not move, and therefore sets
The displacement monitoring component being placed on the first montant 13 and the second montant 14 then will not be stretched or shorten, thus displacement can be avoided to supervise
Survey the inaccurate problem of monitoring result of component.
As shown in Figure 10, connecting shaft 8 therein includes metallic rod 16 and is arranged on the metal batten in described metallic rod 16
17；The end of described metallic rod 16 is provided with the installing hole 15 matching with described installation axle 8, so that described installation axle 8 is pacified
It is contained in described installing hole 15；The plane of described metal batten 17 and the diameter parallel of described metallic rod 16, and described bonding jumper
