Connection, the cylindrical sleeves inner ring are evenly distributed with several keys, and the link block outer ring is evenly distributed with several keyways, and is drilled at link block center
Through-hole, the link block are interference fitted by the key of link block keyway and cylindrical sleeves and are installed, uniformly distributed several on the link block
That axially gets through steps up block slot, described to step up block and step up block slot interference fit to connect.
Preferably, the cylindrical sleeves inner ring is evenly distributed with four keys, and the link block outer ring is evenly distributed with four link block keyways, and
Link block keyway and key are interference fitted.
Preferably, respectively have on the Bisector of angle two-by-two of the link block keyway of the link block one axially get through plus
Tight block slot, the number for stepping up block is identical with the number for stepping up block slot, and described step up block and step up block slot interference fit company
It connects.
Preferably, described to step up there are four block slots, it is described to step up there are four blocks.
Preferably, the contact surface that steps up for stepping up block is wavy surfaces.
Preferably, the through-hole diameter is greater than screw diameter.
Preferably, the knife bar, cutter head, cylindrical sleeves, link block and step up block and be all made of steel to be made.
The utility model has the advantages that the present invention proposes a kind of screwdriver that anti-screw is fallen, can screw installation and unload process
In effectively prevent screw to fall, solve prior art problem, structure is simple, and stability is good, have very strong practicability.
