Whether it is screwing or unscrewing, the anti-clamp can prevent the screws from being accidentally lost. Since the safety tube is a slender stainless steel tube, for small places that cannot be reached by human hands, the screw can automatically enter the screw cavity when the screw is unloaded, and can be easily removed under the action of anti-clamp. Since the screw is installed in the screw cavity, the screw can be accurately positioned on the target, and the screw cavity is a metal tube, which can prevent the screw from tipping before entering the target, and is always in line with the screwdriver rod, so that the screw is easily screwed in. Since the screw is installed in the screw cavity, the human finger does not need to touch the screw, so it will not happen that the screw is tipped before entering the target and hurts the finger like when using an ordinary screwdriver. Due to the anti-clamping effect, the screwdriver can carry the screw and nail it into the target in any direction, and the screw will not slide down due to the action of gravity.
How to use the multi-function screwdriver: When screwing, install the screw in the screw cavity, hold the safety tube (or simple handle) with one hand to push the screw tip on the target, and use the other hand to turn the screwdriver handle. When unloading the screw, hold the safety cylinder with one hand to push the screwdriver against the wire, and use the other hand to turn the screwdriver handle.
