Abstract

The invention is a changeable screwdriver in revolving type. A revolving wheel with a plurality of screwdriver heads is contained in a containing trough of a screwdriver main portion, and a screwdriver sleeve and a guide tube which are interlinked with each other are set in the front and the back separately. The guide tube is used for containing a handle with a pulling rod. The pulling rod can push the screwdriver head in the revolving wheel to the screwdriver sleeve for use. A pivot piece is protruding and set in the side of the containing trough of the screwdriver main portion for pivoting a bearing base. The bearing base can be used for containing the revolving wheel, and is pivoted and fabricated by a positioning element. By above-mentioned structures, the revolving wheel can be fabricated in the screwdriver main portion by using the bearing base, and the bearing base can be put outward by the pivot piece as the rotating shaft for changing the screwdriver head or the revolving wheel in convenience. When using the screwdriver, the pivot piece is used for being against the hand of a user to support the operation to achieve the effect of increasing multiple benefits substantially.
