Auxiliary installation device of steel structure surface type strain gauge

The utility model discloses an auxiliary installation device of a steel structure surface type strain gauge. The auxiliary installation device comprises an adsorption piece, a connecting rod and a clamp assembly. The clip assembly comprises a first jacking piece and a shell; the adsorption part is adsorbed on the surface of a steel structure, a shell is arranged on the connecting rod, an iron seat of the strain gauge extends into the shell and is fixed in the shell, the shell is buckled on the surface of the steel structure, the bottom surface of the iron seat is glued after a rough mounting position is adjusted, and the bottom surface of the iron seat is placed on the surface of the steel structure; the iron base is tightly jacked on a to-be-installed face through the first jacking piece, the device is taken down after glue is dried, the defects caused by manual pressing are avoided, the shell and the adsorption piece can rotate relatively in the axial direction of the connecting rod so that the angle can be
