Abstract

The invention relates to a screw extractor, and belongs to the technical field of mechanical assembly. The screw extractor comprises a screw extractor body. The top of the screw extractor body is connected with an extension rod through a connector. A square clamping block is arranged on the top of the extension rod. The top of the square clamping block is connected with a connecting handle. The connecting handle is provided with a clamping opening corresponding to the square clamping block. A screw extraction vessel is arranged on one side of an inner cavity of the connecting handle. One side of the screw extraction vessel is connected with a vessel cover through a movable rotating shaft. A handle is further arranged on one side of the vessel cover. A reverse thread is further arranged on the screw extractor body. A drill bit is arranged at the bottom of the screw extractor body. A detached screw or a screw needing to be installed can be stored through the screw extraction vessel. When the screw is needed or placed, the vessel cover can be pulled open directly through the handle. Meanwhile, a detachable structure is adopted in the connecting handle and the square clamping block, corresponding screw extractors can be conveniently selected for screws of different types, replacing is convenient, the structure is simple, and practicability is high.

Description

technical field [0001] The invention relates to a screw extractor, which belongs to the technical field of mechanical assembly. Background technique [0002] Screws are widely used components for manual removal of broken hexagon head bolts, studs, and hexagon socket screws in machines and equipment. The thread of the extractor is left-hand helical. Standard twist drill, drill a small hole in the center of the bolt section, then insert the extractor into the small hole, then clamp the square head of the extractor with a tap wrench or adjustable wrench, and turn it counterclockwise hard to remove the broken part. The bolts in the machine and equipment are taken out and nailed into the object, which solves the problem that once the screw breaks, it is difficult to take out, which brings great obstacles to replacement and maintenance. The existing screw taker is laborious and troublesome to use. The user often takes a lot of screws during use, which is very inconvenient. Theref...
