The measuring head or the go-no-go gauge is fixed on the floating hole 21, and when measuring, if the measuring head has a position deviation relative to the detected surface of the product, the floating column 2 will generate an offset load force when the measuring head contacts the detected surface, so as to achieve the effect of correcting the position of the measuring head and ensure that the measuring result is not influenced by position error.
