  • Publication number: 20090288525
    Abstract: A screw positioning sleeve assembly capable of quickly connecting a locking tool comprises an inner sleeve slideably received in an outer sleeve, and the moving distance of the outer sleeve varies with the depth of the locking groove, so that the inner sleeve can be engaged with an ordinary tool rod or a screwdriver to screw or unscrew a screw. When screwing or unscrewing, a magnet in the outer sleeve can attract the screw. During the screwing and unscrewing process, the positioning sleeve can move towards the screw to make the magnet keep attracting the screw, thus preventing the screw from screwing or unscrewing falling off. It is noted that the rod body of the tool rod or the screwdriver can connect with the screw positioning sleeve assembly without any additional preformed structure. Therefore, the scope of applicability of the screw positioning sleeve assembly is enlarged considerably.
