Steel column adjusting frame with perpendicularity detection function

The invention relates to the technical field of steel column adjusting frames, in particular to a steel column adjusting frame with a perpendicularity detection function, which comprises a base and a lower positioning frame, a support frame is mounted at the top of the base, a telescopic frame sleeves the top of the support frame, a chuck sleeves the outer side of the telescopic frame, and the lower positioning frame sleeves the chuck. A first connecting rod is connected to one side of the chuck through a groove, an upper positioning frame is connected to one side of the first connecting rod, and the lower positioning frame is arranged at the bottom of the upper positioning frame. A driving gear drives a connecting shaft to rotate through a first rack, a clamping rod is rotated into a groove of a fixing plate, then a screw rod pushes a limiting rod to move through a second connecting rod, the clamping rod is automatically limited in the fixing plate, and a steel column in a lower positioning frame is limited
