ELECTRIC SCREWDRIVER
Document Type and Number:
WIPO Patent Application WO/2015/060288
Kind Code:
A1
Abstract:
[Problem] To enable signal lines to be pulled out from an electric screwdriver with ease. [Solution] An electric screwdriver accessory (50) is externally attached to an electric screwdriver body (10). The electric screwdriver body is equipped with an electric screwdriver drive control circuit (22) that is disposed inside a screwdriver housing (12), a power cord (32) that is connected to the electric screwdriver drive control circuit and passes through a first power cord retention hole (28), and a power cord fixation annular member (34) that is fixed to the outer periphery of the power cord. The electric screwdriver accessory (50) is equipped with an accessory housing (58) that has a second power cord retention hole (72) having a size that enables the retention hole to engage with and fix the power cord fixation annular member. The size of the first power cord retention hole (28) is set such that a gap is formed with respect to the power cord (32) in a state in which the power cord fixation annular member (34) is fixed to the second power cord retention hole (72), thereby enabling signal lines (82) from the electric screwdriver drive control circuit (22) to be wired through this gap.
