Lead wire stretcher

The invention relates to a lead wire stretcher which is used for adjusting the distance between two lead wires. The lead wire stretcher comprises a sleeve, two clamping mechanisms and at least one brake mechanism, wherein the sleeve is of a structure with two open ends; each clamping mechanism comprises a screw rod and a clamping part fixed on the screw rod, the two screw rods are respectively screwed to the two end parts of the sleeve, and the clamping parts can clamp the lead wires; and the brake mechanism is arranged on the screw rods and is used for fastening the lead wires. According to the lead wire stretcher provided by the invention, when the two screw rods are screwed into the sleeve, the distance between the two lead wires is reduced, when the two screw rods are screwed out of the sleeve, the distance between the two lead wires is increased, in addition, when the distance between the two lead wires meets the set requirement, the lead wires are fastened through the brake mechanism, the lead wire stre
