Tool for dismantling positioning pin of fretsaw guide wheel

The utility model discloses a tool for dismantling a positioning pin of a fretsaw guide wheel. The tool for dismantling the positioning pin of the fretsaw guide wheel comprises a support plate, a handle, a main screw rod and a vice screw rod. The middle of the handle is fixedly connected with the tail end of the main screw rod and forms the shape of T. The vice screw rod is fixedly connected at the front end of the main screw rod and coaxial with the main screw rod. Directions of threads on the main screw rod and the vice screw rod are opposite. A threaded hole is arranged in the middle of the support plate and matched with the threads of the main screw rod. The tool for dismantling the positioning pin of the fretsaw guide wheel has the advantages that the main screw rod is matched with the support plate in a threaded mode and the directions of the threads on the main screw rod and the vice screw rod are opposite. The vice screw rod is screwed into the positioning pin and then the support plate is rotated so that the support plate is contacted with an end face of the guide wheel. During the process of rotating the main screw rod, the threads of the positioning pin and the vice screw rod are tightly screwed so as to achieve that the positioning pin is rapidly dismantled without manual prying. Labor intensity is reduced, a coating of the guide wheel is protected from being scraped in prying and safety of operational staff is ensured.
