AI Technical Summary
Technical Problem
Traditional wire breakage extractors are prone to wire slippage or over-drilling during use, and require additional tools for center marking, making operation inconvenient.
Method used
Design a broken wire extractor with a multi-tapered spiral groove and a gradually changing pitch cutting cone. Combined with a pointed structure, it is used to screw into the broken wire and mark the center, avoiding wire slippage and over-drilling. It is suitable for narrow spaces.
Benefits of technology
It improves the success rate of broken wire removal, simplifies the operation process, reduces reliance on additional tools, and is particularly suitable for disassembly in confined spaces.

Abstract
The utility model provides a broken wire extractor which comprises a connecting rod, one end of the connecting rod is provided with a broken wire extracting conical head, the other end of the connecting rod is cut to form a connecting seat, the surface of the broken wire extracting conical head is provided with a plurality of spiral grooves with different tapers in the length direction of the broken wire extracting conical head, the spiral directions of the spiral grooves are the same, and the connecting seat is connected with the connecting rod. And the distances between every two adjacent spiral grooves are the same. According to the broken wire extractor provided by the utility model, a plurality of spiral grooves with different tapers are formed in the surface of the broken wire extracting conical head along the length direction of the broken wire extracting conical head, so that the phenomenon of wire slipping or excessive drilling between the broken wire extracting conical head and a hole punched in a broken wire can be effectively avoided, and the success rate of extracting the broken wire is greatly improved; the tip is arranged, so that the broken screw extractor can be used for being matched with a hammer head to make a center mark in the middle of the broken section of the broken screw during use, a user does not need to find a tool for making the center mark, and great convenience is brought to the user.
