To achieve these goals, the technical scheme that the utility model adopts is: the anti-error suction cover of a kind of magnetic screw driver, comprise insulation body, and described insulation body has the through hole that mates setting with the knife bar of magnetic screw driver.
Based on above-mentioned, in described through hole, be provided with annular friction band.
Based on above-mentioned, the shape of cross section of described insulation body is C shape.
A kind of magnetic screw driver, comprises magnetic screw driver and insulation body, and described insulation body has the through hole that mates setting with the knife bar of magnetic screw driver, and the knife bar of described magnetic screw driver is through described through hole setting.
Based on above-mentioned, in described through hole, be provided with annular friction band, described annular friction strap is on described knife bar.
Based on above-mentioned, the shape of cross section of described insulation body is C shape, and described insulation body is arranged on described knife bar.
Based on above-mentioned, on the knife bar of described magnetic screw driver, have and mate the cannelure arranging with described through hole.
The relative prior art of the utility model has substantive distinguishing features and progress, specifically, the utility model is sheathed on insulation body on magnetic screw driver knife bar, make power worker using knife bar when magnetic screw driver due on magnetic force attracted to charged iron and steel parts, insulation body is just by knife bar and charged isolated the coming of iron and steel parts, avoid magnetic screw driver charged, and prevented that multiple charged iron and steel parts are by accidents such as magnetic screw driver are short-circuited.The anti-error suction of this magnetic screw driver cover and the magnetic screw driver with this anti-error suction cover can effectively prevent that magnetic screw driver from adsorbing nearly charged iron structure by mistake, eliminated the potential safety hazard such as electric shock or short circuit.
