Furthermore, it is a plurality of the both sides inside of shrink board all rotates and is connected with a plurality of pivots, and is a plurality of equal fixedly connected with gyro wheel in the pivot.

Furthermore, a plurality of the rollers are connected with the inserting plate in a rolling manner.

Furthermore, a return spring is fixedly connected between the contraction plate and the inserting plate.

Furthermore, the one end fixedly connected with splint of shrink board, one side of splint, shrink board and picture peg is the first protection of fixedly connected with pad and the second protection pad respectively.

Furthermore, the middle of the rear side of the shell is connected with a conical pipe through a bolt.

The utility model has the advantages that:

the utility model discloses a casing that sets up, the knob, the spout, splint, two-way threaded rod, first protection is filled up, the shrink board, the second protection is filled up, the picture peg, the connecting plate, the conical tube, the gyro wheel, reset spring, the apparatus further comprises a rotating shaft, can adjust the interval between clamp splice and the casing, under reset spring's effect, the clamp splice can press from both sides the lower extreme of digital display inclinometer tightly, rotating knob regulation rotation knob drives two-way threaded rod and rotates again, adjust the distance between the connecting plate, make the plane that the lower square picture peg and shrink board constitute press from both sides the digital display inclinometer tightly, thereby fix the digital display inclinometer on this device, be connected this device with calibrating device through the conical tube can.
