The invention relates to a dial gauge stand for measuring the parallelism of a screw on a bedway. The dial gauge stand comprises a bridge plate and a gauge stand fixed together with the bridge plate through an inside hexagon cylindrical bolt, wherein the bridge plate and the gauge stand form an L shape; the gauge stand is provided with an upper fixing sleeve through a top bolt; an open slot is arranged inside the upper fixing sleeve; an L-shaped upper contact is fixed inside the open slot through a cylindrical pin; a concave pit is arranged on the vertical edge of the upper contact; a compression spring is arranged inside the concave pit; a lower fixing sleeve is arranged on the gauge stand; a lateral contact is arranged inside the lower fixing sleeve; the compression spring is arranged between the lateral contact and the lower fixing sleeve, and a pull pin for preventing the lateral contact from separating is arranged on the side surface of the lateral contact.. Compared with the prior art, the dial gauge st
