Patent attributes
A slip-resistant magnetic sheath includes a hollow sleeve that can be fit onto the screwdriver's shank. A magnetic part positioned at least on one end of the hollow sleeve, provides auxiliary attraction to improve the connection between the shank and the screw with a fastening rim and groove set correspondingly on the sleeve of the magnetic sheath and the shank. The groove allows the fastening rim to move within a pre-set distance so that the magnetic sheath can slide within certain distance and not fall off the shank. The invention installed on an electrical screwdriver can effectively address the slipping problem caused by shocking. The forceful magnetic attraction of the magnetic sheath can prevent the screws from slipping and therefore improve working efficiency.
