The invention discloses a quincuncial contact elastic pressure detection device which comprises a mounting sleeve, a connecting ring mounted at the front end of the mounting sleeve, spacer bars and measuring probe rods, wherein flanges are arranged on the circumference of the inner side of the connecting ring; a spacer bar is fixed to each flange; a measuring probe rod is hinged between every twoadjacent spacer bars; an elastic connecting device is arranged on the outer side surface of the rear end of each measuring probe rod; each elastic connecting device is correspondingly connected with amicro force measuring sensor; the micro force measuring sensors are fixed to the inner side of the mounting sleeve; a mounting plate and a driving device are fixed to the rear end of the mounting sleeve; a driving conical rod is arranged at the front end of the driving device; and when the driving conical rod stretches or retracts, the rear ends of the measuring probe rods are radially expanded or contracted and the front ends of the measuring probe rods are radially contracted or expanded. The measuring probe rods are elastically expanded to contact with contact fingers to perform measurement, and the measuring probe rods and the elastic connecting devices are used for carrying out conversion measurement, so that no external force impact interference exists in the measuring process, themeasuring efficiency is high, and measurement is accurate and reliable.
