FASTENING MACHINE WITH REACTION RECEIVER

摘要

PROBLEM TO BE SOLVED: To easily detach a fastening machine from a nut after fastening is completed regarding a handy type nut fastening machine with a reaction receiver. SOLUTION: The fastening machine is provided with a fastening socket 4 and the reaction receiver 5 and constituted to rotationally drive the fastening socket 4 by reducing speed by a built-in motor 2 and reduction mechanism 3. The motor 2 is linked with a control part 7, and the control part 7 intercepts a current flowing to the motor 2 by a fastening completion signal from a detecting means 70 for detecting the fastening completion. After the lapse of a fixed time when the inertial rotation of the motor 2 is lowered to the ignorable extent to reversely rotate the motor 2 from the current interception, the motor 2 is reversely rotated only for an instant to release the support of the reaction receiver 5.
