MOTOR-DRIVEN SCREWDRIVER |
摘要 |
A motor-driven screwdriver accessory is externally attached to a motor-driven screwdriver body. The body has a drive control circuit disposed in a screwdriver housing, a power supply cord connected to the drive control circuit and extended through a first power supply cord holding hole, and a securing annular member secured to the outer periphery of the power supply cord. The accessory has a housing having a second power supply cord holding hole sized to allow the securing annular member to be engagingly secured thereto. The first power supply cord holding hole has a size allowing formation of a clearance between the first power supply cord holding hole and the power supply cord in a state where the power supply cord securing annular member is secured to the second power supply cord holding hole, thereby enabling a signal line from the drive control circuit to be routed through the clearance. |

1. A motor-driven screwdriver comprising a motor-driven screwdriver body and a motor-driven screwdriver accessory to be externally attached to the motor-driven screwdriver body;
the motor-driven screwdriver body including: a screwdriver housing; a motor-driven screwdriver drive control circuit disposed in the screwdriver housing; a first power supply cord holding hole provided in a rear end surface of the screwdriver housing; a power supply cord connected to the motor-driven screwdriver drive control circuit and extended to an outside of the screwdriver housing through the first power supply cord holding hole; and a power supply cord securing annular member secured to an outer periphery of the power supply cord; the motor-driven screwdriver accessory including an accessory housing to be secured to a rear end portion of the screwdriver housing, the accessory housing having a second power supply cord holding hole of a size allowing passage of the power supply cord extending from the motor-driven screwdriver body and also enabling the power supply cord securing annular member to be engagingly secured to the second power supply cord holding hole; wherein the first power supply cord holding hole has a size allowing formation of a clearance between the first power supply cord holding hole and the power supply cord extended through the first power supply cord holding hole in a state where the power supply cord securing annular member is secured to the second power supply cord holding hole, thereby enabling a signal line for taking out a required signal from the motor-driven screwdriver drive control circuit to be routed through the clearance. |
