ABSTRACT:
A portable screwdriver has a tip cartridge movably mounted inside the portable screwdriver. The tip cartridge can protrude from and be stored in the portable screwdriver and has multiple clamps formed, which hold the tips that can be individually detached from the tip cartridge and mounted on the portable screwdriver. Thus, the portable screwdriver is compact and facilitates carrying. Moreover, the portable screwdriver stores the associated tips inside and effectively prevents the tips from being lost.
