[0019] 4. The high-stability intelligent power meter has a retracting mechanism. When the storage box needs to be picked up and carried, the inclined plate, mounting plate, rectangular plate, plug-in plate, slide plate, third spring, connecting rod, connecting strip and bolts are used together. When the force on the pulling plate is released, the fourth spring can drive the sliding plate to retract into the rotating plate through the force-bearing plate, so that when the power meter body is in use, the pulling plate and the fixing plate cannot limit the power meter body, which makes it more convenient for the staff to use the power meter body.
