[0044] The present invention provides an anti-theft protection mechanism. After the main body of the power audit instrument is clamped and fixed, the protection driving screw is rotated. The rotation of the protection driving screw drives two groups of protection driving sliders to move toward each other. The opposite movement of the protection driving sliders drives the shielding protective parts to move toward each other. The opposite movement of the shielding protective parts realizes the protection of the main body of the power audit instrument, prevents electricity thieves from destroying the main body of the power audit instrument through strong magnetism, ensures the stable operation of the main body of the power audit instrument, and further ensures the stable operation of the power system. When the two groups of shielding protective parts are in contact, the first protective part and the second protective part are fixed by the protection lock, preventing outsiders from opening the shielding protective parts privately.

[0045] The present invention provides an anti-theft protection mechanism. When the inspector opens the main body of the meter box, the door of the main body of the meter box no longer squeezes the cleaning drive rod, and the cleaning drive rod moves forward under the action of the cleaning connection spring. The cleaning drive rod moves forward and drives the first cleaning member to move forward. The first cleaning member moves forward to clean the observation window. At the same time, the first cleaning member moves forward and drives a group of cleaning connection magnetic blocks in the front to move forward. The cleaning connection magnetic blocks move forward and no longer attract a group of cleaning connection magnetic blocks in the rear. At this time, the second cleaning member moves backward under the action of the cleaning connection spring, and the second cleaning member cleans the observation window. During the operation of the main body of the power inspection instrument, when the observation window is damaged by human beings, the anti-theft trigger member rotates under the action of the anti-theft trigger spring. The rotation of the anti-theft trigger member no longer squeezes the anti-theft trigger button. The anti-theft trigger button controls the anti-theft buzzer to turn on, and the anti-theft buzzer makes a sound, thereby warning the electricity thief. BRIEF DESCRIPTION OF THE DRAWINGS
