A swing link is fixed between the left and right low plates, and an symmetrical upper-left and an upper-right flexible plate are fixedly connected with the two ends of the left, right low plates and the swing link respectively. A fixed block is arranged between the upper-left and upper-right flexible plate, and a sensor connected by a hexagonal bolt is arranged at the bottom of the fixed block. A pendulum shaft is connected between the upper-left and upper-right flexible plate, around which a pulley is nested. Outer shield rings and bearings are arranged at both ends of the pendulum shaft, and are fixed by gaskets, spring cushions and nuts after penetrating the upper-left and upper-right flexible plates. A circuit board seat is arranged at the left-low board, and the circuit board is connected with the sensor by connectors. The utility model is accurate in force measurement, convenient in adjustment and is not influenced by environment, climate, friction lubrication and other factors, thereby solving the zero point drift caused by improper repair and maintenance which led to the inaccuracy of the measurement.
