As further improvement of the utility model, on the base of locating piece both sides, be equipped with clamp device; Clamp device is measured piece fixedly, improves detection speed;

As further improvement of the utility model, the two ends adjacent with the vertical guide rail seat with the horizontal guide rail seat respectively at the right angle track base are equipped with a latch, are equipped with lock-screw on every latch; After having detected,, avoid breaking the dial gauge gauge head by lock-screw lockable horizontal guide rail seat and vertical guide rail seat;

As further improvement of the utility model, on base, also be provided with the slide vertical with locating piece, positioning seat A is loaded in the slide by guideway; Be convenient to adjust the position of positioning seat A;

As further improvement of the utility model, described measurement pin and register pin are taper pin; Be convenient to locating piece and workpiece are carried out accurate in locating, improve accuracy of detection;

In sum, the utlity model has the high and high advantage of detection efficiency of measuring accuracy, satisfied the needs that use the production scene.
