Motor-driven screwdriver operation information indicator and motor-driven screwdriver with operation information indicating function

摘要

A motor-driven screwdriver operation information indicator is retrofittable to a motor-driven screwdriver to indicate information related to an operation of the motor-driven screwdriver. An indicator housing of the operation information indicator is secured to a supporting and securing member configured to be secured to an outer peripheral surface of a screwdriver housing of the motor-driven screwdriver, thereby holding the indicator housing at a rear position of a rear end portion of the motor-driven screwdriver. An indication control circuit disposed in the indicator housing is connected to at least one of a motor-driven screwdriver drive control circuit and an external control circuit to receive a signal from the circuit connected thereto. The indication control circuit transmits a signal related to an operation of the motor-driven screwdriver on the basis of the received signal and indicates information related to the operation of the motor-driven screwdriver on an operation information indicating part.
