A meter installation electricity connection electric wire sorting device disclosed in the invention includes a base, at both side of that upper end of the base, a partition plate is fixedly connectedbetween the two sides of the base, a lead screw No. 1 is connected to one side of that partition plate, 3 slide grooves are arranged on one side of No. 1 screw rod and on that inner side of the base,by providing a movable sliding plate No. 1 and a movable sliding plate No. 2 on the base, you can adjust the distance between the two tweezers, as a plurality of No. 2 slide groove are arranged on that wire manage board, and a plurality of inlet barrels are uniformly connected to the No. 2 sliding groove, and a plurality of threading holes with different diameters are arranged in different inlet barrels, can satisfy the different diameter and size of the electric wire to pass through, a magnet is arrange on both sides of that wire inlet barrel, and two or three wire inlet barrel can be attracted to form a group through the magnet, so that it is more convenient for an operator to distinguish and connect the electric wires. The invention has simple and novel structure, is easy to operate, saves time and labor, and greatly improves the working and use efficiency of the wire inlet barrel installation and connection device.
