One threaded hole for being used to be connected on testing stand；Each fixed column in 3 fixed columns with the word of falling T
The perpendicular direction build-in of type support plate plate face is in the uniformly distributed square hole of described three in the inverted T font support plate
In one square hole；There is the major thread hole of an accessible flexible connecting line respectively near two ends of each fixed column
With a minor thread hole for the screw association part that is connected；3 screw association parts are by clip-like body, screw and in institute
State screw rod end and carry and can be used for compressing and the packing ring of release relay inlet-outlet line composition；Have one at the top of the clip-like body
One hexagon socket head cap screw that may pass through in 3 hexagon socket head cap screws is arranged at a screw hole that can screw in the screw, bottom
The hole of body；The lower section of packing ring described in the clip-like body, i.e. institute are set in the one end of the fixed column with minor thread hole
The one end for stating each fixed column is coated with the screw association part, and the body of the hexagon socket head cap screw passes through the clip-like body bottom
The hole in portion is fastened in the minor thread hole in the fixed column.
The utility model has the advantages and positive effects of：Testing stand fixture realizes assembly parts modularization, simple in structure,
Process for machining and manufacturing requirement is low, easy to assemble and use, therefore reduces manufacture and the operation maintenance cost of testing stand, shortens
Install debug time is tested, improves the work efficiency of testing stand.

Embodiment
For that can further appreciate that the invention, features and effects of the utility model, the following examples are hereby given, and coordinates
Attached drawing describes in detail as follows：
As shown in Fig. 1-1,1-2,2-1,2-2,3-1,3-2,4-1,4-2,4-3：Inverted T font support plate 2 passes through both ends
Threaded hole 21,22 is fixed on Detecting data panel, and three identical square fixed columns 11,12,13 are (in Fig. 1-1,1-2 only
The structure diagram of fixed column 11 is given, other two are identical with this) it is respectively embedded into inverted T font support plate upper end three uniformly
In square hole 23,24,25；Screw association part 31 is made of clip-shaped piece 311, screw 312, packing ring 313, and screw association part 32 is by pressing from both sides
Shape part 321, screw 322, packing ring 323 form (structure diagram of screw association part 31 is only gived in Fig. 3-1,3-2, other
Two are identical with this), screw association part 33 is made of clip-shaped piece 331, screw 332, packing ring 333；Screw association part 31,32,33
In 311,321,331 lower end of clip-shaped piece respectively the taper end minor thread hole 112,122,132 with fixed column 11,12,13 by interior
Hex bolts 41,42,43 is fixed.Three inlet-outlet lines of relay are passed through into screw association part during testing stand detects relay
