Portable verification device for electronic scale

The utility model relates to a portable verification device for an electronic scale, and belongs to the field of physical detection. The portable verification device for the electronic scale comprises a portable integrated verification instrument, an adjustment base and a force-transmitting frame (not used if a pulling-type sensor is used). A force-giving mechanism is composed of worms, a worm gear and a bolt, wherein the bolt is embedded into the worm gear. The integrated verification instrument for the electronic scale is composed of a high-precision weighing sensor, a display device, the force-giving mechanism and a shell. The verification device is installed above or under a sensor under verification. The sensor under verification is verified through hand-cranking to give force and displaying the force-giving value, namely, weight. During verification process of going up and going down, the required force can be given easily at any point of the measuring range and can be maintained. Meanwhile, the total s
