Abstract

The invention discloses a movable-top sleeve special for a spanner for assembling and disassembling three-difference thread anti-theft screws, which is a tool for assembling and disassembling non-standard fastener screws. The movable-top sleeve comprises an outer sleeve hollow cylinder (11) and an inner sleeve solid cylinder (21) or an inner sleeve hollow cylinder (31) and the like, wherein an inner through hole wall (17) of the outer sleeve hollow cylinder is provided with a right hand thread (171) which is clockwise screwed on the inner through hole wall of the outer sleeve hollow cylinder and a left hand thread (172) which is counterclockwise screwed on the inner through hole wall of the outer sleeve hollow cylinder; and the peripheral wall (24) of the inner sleeve cylinder is provided with a right hand thread (241) which is clockwise screwed on the peripheral wall of the inner sleeve cylinder or a left hand thread (242) which is counterclockwise screwed on the peripheral wall of the inner sleeve cylinder. When the movable-top sleeve is matched with the three-difference thread anti-theft screws, adjustable spanners and the like, a large number of easily-stolen facilities such as power facilities and the like arranged outdoors can be fixedly assembled, changed or strengthened for use in an anti-theft mode, and the movable-top sleeve has obvious social benefit.
