The lower extreme and the screw hole of support are connected, so the support is fixed on the base, and the gag lever post can reciprocate along the slide opening, but the gag lever post receives the thrust of spring and will hug the slide bar, when grabbing the handle with the hand and making the slide bar lateral shifting, the gag lever post will insert main spacing hole or vice spacing hole. When the measuring column is used for measuring the cross hole of the automobile steering arm, the limiting rod is in a state of being inserted into the main limiting hole, after measurement is completed, the shifting block is lifted upwards by a hand, the shifting block, the limiting rod and the stop lever move upwards together, then the limiting rod breaks away from the main limiting hole, then the sliding rod transversely moves away from the cross hole of the automobile steering arm, then the limiting rod is inserted into the auxiliary limiting hole, finally the quick clamp is opened, and the automobile steering arm after detection is taken away. Because the stop lever inserts in the retaining groove, shifting block, gag lever post can only reciprocate, can not circumferential direction rotation, can guarantee like this that the gag lever post inserts main spacing hole or vice spacing hole smoothly. The left limiting block and the right limiting block can limit the limit positions of the sliding rod in transverse movement, and when the sliding rod is located at the two limit positions respectively, the limiting rod can be just inserted into the main limiting hole or the auxiliary limiting hole smoothly.
