Compared with the prior art, the utility model has the advantages of:

(1) The utility model is suitable for a displacement detection equipment of various not unidimensional, equidimensional not, because displacement detection equipment arranges the box body in, can select the box body according to displacement detection equipment's size, according to the distance of the movable body of a vice and the fixed body of a vice among the size adjustment bench vice of box body to nimble adjustment clamping part all reaches sliding fit with the box body of different models. The box body structure of cuboid can only can its length direction of bench vice remove with bench vice control box body, and can not take place the displacement change in other directions to guarantee the measuring accuracy, eliminate the displacement error in other directions. The base passes through elevating system and connects the percentage table, and the height-adjustable of percentage table is applicable to the box body of unidimensional not.

(2) Through the weight of adjustment liquid jar, can change the traction force to the box body, because there is frictional force in each device, the pulling force that the box body received and its displacement nonlinear relation, so the utility model discloses replace the weight with the liquid jar, can satisfy intermediate distance displacement and non-equidistance displacement measurement demand in the experiment.

(3) The probe level of percentage table sets up, and is parallel with clamping part length direction, nevertheless does not extrude with the contact of box body outer wall under initial condition, and like this, when the box body took place the displacement, the distance that its removed can be got off by the accurate record of percentage table, and the displacement detection equipment that is located the box body also works and takes notes the displacement, and we only need compare two displacements, can confirm whether there is the error displacement detection equipment.

(3) Additionally, the utility model discloses the accessible adjustment box body the position, erect put, put transversely, rotate operations such as 90 for three-dimensional displacement detection equipment's error detection, and data accuracy is high, and the reliability is high.
