[0010] The beneficial effects of the present invention are:

[0011] 1. The present invention provides a wire bundling mechanism. When installing the electric meter, one end of the wire is connected to the wiring board through the extrusion plate, the support roller, the moving roller and the guide roller in sequence. The wire that is too long is wound through the wire bundling roller. During the process, when the wire is pulled, the support roller rotates under the pull of the convex ridge and the wire. At this time, the support shaft drives the first pulley to rotate with the rotation of the support roller, and the fixed shaft drives the gear to rotate under the action of the second pulley and the belt. At this time, the gear drives the rack to slide to one side through meshing. At this time, the moving roller slides to one side of the guide port under the action of the rack and the gear. At this time, the distance between the moving roller and the guide roller will gradually increase during the sliding, and the wire will be pulled in an S shape under the action of the moving roller and the guide roller, so as to increase the tension of the wire, thereby facilitating the wiring of the electric meter and preventing the wire from being loosely installed due to the long length of the wire during the wiring process, so that the wire droops downward under the action of its own gravity, causing the wiring end of the wire to be dragged, and then causing the wire to fall off and affect the work of the electric meter;

[0012] 2. The dust removal mechanism of the present invention is provided. When the electric meter is installed, the electric meter is heat-dissipated by the fan. During the process, the wind blown by the fan will act on the blades. Since the blades are obliquely arranged on the outer wall of the second rotating rod, when the wind acts on the obliquely arranged blades, the blades will drive the second rotating rod to rotate under the action of the wind. At this time, the first push rod will rotate synchronously with the rotation of the second rotating rod. Since the first push rod and the second push rod are provided with a plurality of continuous protrusions on the opposite side, as the first push rod rotates, the second push rod will drive the push plate to move downward under the action of the protrusions, and the push plate will squeeze the airbag when moving downward. At this time, the gas inside the airbag will be transported to the inside of the exhaust pipe through the conduit after being squeezed. Since one end of the exhaust pipe is inclined toward the position of the terminal block, the airflow blown out of the exhaust pipe will act on the terminal block, so as to process the dust adhered to the wiring terminal of the wire, and prevent the dust from adhering to the wiring terminal of the wire so that the dust damages the wire, thereby affecting the operation of the electric meter.
