Benefits of technology

The disclosed thread repair tool has been designed to fit different screw diameters by adjusting the distance between the repair blade and the rollers. This makes it easier to repair threads on screws with different diameters, as compared to previous devices which required multiple dies. This invention improves the efficiency and adaptability of thread repairs.

Problems solved by technology

For repairing threads with different designs, the conventional tool would need plenty of said dies, being inconvenient to both carry and use.

Abstract

A thread repair tool for repairing damaged threads on a screw is disclosed. The thread repair tool includes a tool body and plural rollers. The tool body has at least one surface provided with a thread repair blade that has a tooth pitch identical to a thread pitch of the threads to be repaired. The rollers are separated from the tool body by a gap. The thread repair tool further includes an adjusting means for adjusting the gap so as to hold the screw between the tool body and the rollers.

Description

BACKGROUND OF THE INVENTION[0001]1. Technical Field[0002]The present invention relates to thread repair devices, and more particularly to a tool for repairing damaged male threads.[0003]2. Description of Related Art[0004]Thread repair tools are designed for repairing screw threads with thread cutting molds having corresponding screw diameters. One conventional thread repair tool, as disclosed in Japan Patent Publication No. 2006-326731A, is composed of two die halves that only fit threads of a certain thread pitch, screw diameter and screw type. For repairing threads with different designs, the conventional tool would need plenty of said dies, being inconvenient to both carry and use.SUMMARY OF THE INVENTION[0005]The primary objective of the present invention is to provide a thread repair tool that is capable of dealing with screws of various diameters, without using different dies.[0006]According to the present invention, a thread repair tool used for repairing a set of damaged thr...
