On headgear, screw is tightened or unscrewed；Second, being directly connected with a handle on tool bit casing, hand is acted on handle to screw
Turned；Third, tool bit casing is connected by knife bar with handle, torque is increased, it is more laborsaving.
Further, the material of the handle is rubber or plastics, and the handle surfaces are provided with anti-skid design, increase people
Friction between hand and handle, people can preferably have an effect.
Compared with prior art, the beneficial effects of the utility model are：
Nested cutter head is big model cutter head nesting ting model segment design, and the cutter head of corresponding model and screw progress are mutually embedding
Close, conveniently turn, it is not necessary to select cutter head manually, reach a screwdriver and coordinate multiple model hex(agonal)screw purposes.Cutter head shape
Shape can arbitrarily change according to screw end model size, and therefore, it can be applied to the screw of various different models, so as to full
Foot is easy to carry and puies forward efficient demand.
