Abstract

The present invention provides an auxiliary magnetic sleeve for anti-slip screwdriver bit, in which the magnetic sleeve is a hollow sleeve enveloping an existing screwdriver bit in its bore and providing auxiliary attaching force with a magnetic member disposed at the other end so as to increase the tight attachment between the screwdriver bit and a screw. The present invention is characterized by the bore of the magnetic sleeve and the screwdriver bit as well as a fitting edge and a fitting groove disposed correspondingly, wherein the fitting groove allows the fitting edge to move within the predetermined distance such that the magnetic sleeve can be slid by the predetermined distance and securely confined on the screwdriver bit to attain the anti-slip object. When the magnetic sleeve is applied to an electric screwdriver, the issue that strong shock generated by electric screwdriver and screw is easy to come off can be significantly improved by the assembly of the magnetic sleeve, thereby achieving to prevent screw from falling off by using the magnetic sleeve to strongly attract screw and making the operation more smooth, efficient, practical and innovative.
