The invention relates to a general porous spacing space relative location degree measuring tool and belongs to the machinery manufacturing technology field. The measuring tool comprises a frame body formed through fixed connection of frame strips, wherein the frame body corresponding to the position of each to-be-detected hole is fixed with a rectangular rail frame, two pairs of opposite edges ofeach rectangular rail frame are respectively composed of vertically-staggered edge rails, the edge rails and adjustment bolts form moving pairs, the rectangular rail frame is internally equipped witha positioning moving block, four edges of the positioning moving block respectively have thread holes in thread connection with the adjustment bolts on the adjacent edge rails, the middle of a positioning surface of the positioning moving block is provided with an outer-big inner-small positioning conical hole, the positioning conical hole is inserted with a positioning pin, and the positioning pin is composed of a conical handle matched with the positioning conical hole and positioning bosses which are arranged at a big-end central portion of the conical handle and an excircle and are matchedwith an inner diameter of the to-be-detected hole. The measuring tool is advantaged in that the porous space relative position measuring tool has certain universality and use flexibility, examinationefficiency is improved, management cost is saved, and multi-variety matching and series product production demands can be better satisfied.
