Claims

[Scope of utility model registration request]

A bit that fits into the tightening screw, a bit guide that surrounds the bit and reciprocates on the bit rotation axis, and aligns and holds the tightening screw diagonally upward from below the bit guide on the bit rotation axis. A stand-type chute consisting of a chute that separates the tightening screws one by one near the bit rotation axis of the chute, a separation claw that separates the tightening screws one by one near the bit rotation axis, and a catch that holds the screws separated by the separation claw on the bit rotation axis. In a headed screw holding device for a screw tightening machine, the catch can be opened and closed left and right with respect to the screw alignment surface of the chute so as not to interfere with the reciprocating movement of the bit guide, and the A stand-type screw tightener, characterized in that it has an inclined surface connected to the inclined surface of the chute, and further has a trapezoidal hole arranged at the intersection of the inclined surface and the axis of rotation of the bit, and serves as a holding part for the screw. Machine head screw retainer.
