The improved special tool for repairing and scraping the bearing bush further comprises a handle sealing head, wherein an external thread is processed at the end part of the handle sealing head and is connected with the internal thread of the handle in a matched mode.

The improved special tool for repairing and scraping the bearing bush has two handles, namely a long handle and a short handle.

The improved special tool for repairing and scraping the bearing bush is characterized in that a tool bit of the scraper is of a triangular prism structure, the top end of a knife edge is arc-shaped, and each knife face close to the top of the knife edge is provided with a chip removal groove.

The improved special tool for repairing and scraping the bearing bush utilizes high-speed steel (HSS) with higher hardness and better wear resistance and heat resistance to replace T12A high-carbon steel as a manufacturing material of the scraper, and the service life of the scraper is prolonged. The knife edge is processed into an arc shape, so that the attaching surface of the scraper and the bearing bush is larger, and the working efficiency of the maintenance of the scraping bush is improved. The scrap discharge groove is formed in the position close to the cutter opening, black gold scraps can be effectively and timely discharged when the tile is scraped, and the phenomenon that the black gold scraps are accumulated at the cutter opening to influence the tile scraping effect is prevented. The processing of scraper bottom both sides has the external screw thread, and long handle and short handle both ends processing have the internal thread, and processing has a plurality of handle head in addition, can be respectively through the combination of long handle, short handle, handle head and scraper, and nimble change length is in order to satisfy the bush of different specification and dimension and repair and scrape the requirement, and long handle, short handle, handle head and scraper accessible threaded connection make up portable.

The utility model has the advantages that: its simple structure, long service life and can be respectively through the combination of long, short handle and triangle scraper, change length in a flexible way and repair the requirement of scraping in order to satisfy the axle bush to different specification and dimension, long handle, short handle, handle head and scraper accessible threaded connection make up, portable, the binding face of arc edge and axle bush is bigger, can effectively improve the work efficiency of scraping the tile and overhauing.
