Device also includes at least three groups micro- change connection components, micro- change connection component be arranged on two corresponding pressing plates it
Between, micro- change connection component includes support frame and fixed support, and support frame is fixedly connected with one of pressing plate and the vertical pressing plate
Set, support frame end connection displacement transducer, fixed support is fixedly mounted on another pressing plate and the parallel pressing plate is set
Put, fixed support outer end is provided with clamping section, clamping section is hatch frame, and hatch frame includes and displacement transducer shape phase
Fixing bolt is installed in corresponding duct and the fixed part provided with fixing hole, fixing hole.
The technical scheme that the utility model is further limited is：
The contact of aforementioned displacements sensor can carry out elastic telescopic.
Foregoing support frame is rigid L-type structure, and the short side of support frame is fixedly connected with one in two corresponding pressing plates,
And the parallel pressing plate, vertical pressing plate in long side of support frame.
The beneficial effects of the utility model are：
The device of the utility model design is corresponding two-by-two to set provided with six pressing plates, and at least one is set between each two
Individual micro- change connection component, for the rock deformation amount on direction where measuring two block pressur plate, micro- change connection component includes one
