Claim 1:
2. A measuring principle of the miniature combined multi-axis force sensor structure according to claim 1, wherein eight strain gauges are stuck on the horizontal main beams and the vertical main beams to form two Wheatstone bridges, four strain gauges are stuck on an upper surface and a lower surface of the horizontal main beams to form a bridge circuit sensitive to an upper and lower resistance FZ, four strain gauges are stuck on a side surface of the vertical main beams to form a bridge circuit sensitive to a torsional torque MZ, when force/torque acts on the cross beam, the sensor deforms, and a resistance value of the strain gauge at corresponding position changes, causing an output voltage of a corresponding bridge to change, and a value of the force/torque can be obtained by measuring a variation of the voltage.
