Abstract

The invention discloses a high-strength screw extractor. The high-strength screw extractor comprises a large head and a handle which is integrally connected with the rear end of the high-strength screw extractor, cutting edges are formed on the large head, and threads are formed on the surface of the large head. The high-strength screw extractor has the advantages that the threads are formed on the large head portion where the screw extractor acts on a screw so that more fastness are achieved when the high-strength screw extractor is connected with the screw, the connecting strength of the screw extractor is improved, meanwhile the acting force during striking can be reduced, the damage to the high-strength screw extractor can be reduced, the service life is prolonged, and more convenience and reliability during usage can be obtained.

Description

technical field [0001] The invention relates to a screw extractor. Background technique [0002] Screws are widely used parts. They are nailed into objects. Once they break, they are difficult to remove, which brings great obstacles to replacement and maintenance. The use of the existing screw extractor is laborious and cumbersome to use, and the screw extractor itself is easily damaged due to the need to strike the screw extractor vigorously during use. Contents of the invention [0003] Purpose of the invention: In view of the above problems, the purpose of the invention is to provide a high-strength screw extractor, which is labor-saving, convenient and not easily damaged. [0004] Technical solution: a high-strength screw extractor, including a handle with a large head and a rear end connected into one body, a cutting edge is provided on the large head, and threads are provided on the surface of the large head. [0005] The threads are reverse threads. [0006] The ...
