Multifunctional mechanical measurement tapping device

A multifunctional mechanical measurement tapping device comprises a base. The lower surface of the base is a plane. A fixed column perpendicular to the lower surface is fixed to the upper surface of the base. A bearing is installed outside the fixed column. A measurement instrument is installed on the bearing and fixed to the outer portion of the bearing and the fixed column is sleeved with the measurement instrument. The measurement instrument comprises a horizontal measurement instrument and a perpendicularity measurement instrument, wherein the instrument end face of the horizontal measurement instrument and the instrument end face of the perpendicularity measurement instrument are perpendicularly arranged. A screw tap installation groove is formed in the center of the lower surface of the base. At least two chutes arranged at intervals and communicated with the screw tap installation groove are formed in the side of the screw tap installation groove. Screw tap chucks are installed at the inner ends of the chutes. Screw taps are jacked and fixed through the inner ends of the screw tap chucks. Locating end faces attached to the screw tap chucks respectively are arranged at the inner ends of the screw taps. The outer ends of the screw tap chucks are connected with springs. The outer ends of the springs are connected with clamping nuts. The clamping nuts are in threaded connection with the interior of the chutes. A rotary handle is installed at the top of the fixed column.
