Abstract

The invention relates to a head-replaceable screwdriver. The head-replaceable screwdriver comprises a cylindrical shell, a cylindrical center support fixed to the interior of the shell, a plurality ofpropelling assemblies arranged in the shell and uniformly distributed around the center support, screwdriver heads with the same number as the propelling assemblies and a fixing tube connected to thebottom end of the shell and used for allowing the single screwdriver head to pass through. When the head-replaceable screwdriver provided by the invention is in use, a hand shank can be pressed downwards to push the propelling assemblies to drive the corresponding screwdriver head to move downwards to pass through the fixing tube, and then the screwdriver can be used. The different screwdriver heads can be replaced like a ball-point pen. Different types of screwdriver heads can be ingeniously replaced on the same screwdriver. Thus, the head-replaceable screwdriver is convenient to carry and has complete functions.
