Abstract: A power tool includes a motor, a switch, a housing, a switching member and a holding member. The housing is a hollow body formed by a first housing part and a second housing part connected with the first housing part. The first housing part has a through hole. The switching member is connected to the switch and includes an operation part exposed outside through the through hole so as to be movable in a specified direction in response to a user's manual operation. The switching member is configured to turn the switch on and off by linearly moving in the specified direction. The holding member is supported by at least one of the first housing part and the second housing part within the housing and configured to hold the switching member between the holding member and the first housing part so as to be linearly movable in the specified direction.

Abstract: A work tool includes a spindle and a clamp shaft. The spindle is supported to be rotatable around a driving axis defining an up-down direction of the work tool. The clamp shaft includes a shaft part and a fixing part. The shaft part extends coaxially with the spindle. The fixing part is coupled to the shaft part on a lower side of the spindle. The clamp shaft is supported to be movable in the up-down direction relative to the spindle. The clamp shaft is configured to be biased upward and to fix the tool accessory to a lower end portion of the spindle by the fixing par. The fixing part is configured to be removable from the shaft part and to be integrally coupled to the shaft part only by moving upward relative to the shaft part.

Abstract: A work tool includes an an elongate outer housing, an elongate inner housing, a motor, a spindle, and a transmitting mechanism. The inner housing includes a first end part, a second end part, an extending part and an elastic connection part. The motor, the spindle and the transmitting mechanism are disposed in the first end part of the inner housing. The first end part is connected to the outer housing via a first elastic member. The second end part includes a power-source-related device configured to enable power supply from a power source to the motor. The elastic connection part includes second elastic members connecting the extending part and the second end part. The second elastic members are spaced apart from each other in a circumferential direction around the longitudinal direction.

Abstract: A power tool enabled to detect an inadvertent rotation at higher accuracy includes a first sensor that detects a first driving information corresponding to a kinetic movement state of the tool body when the tool body is rotated around a longitudinal axis of the tool bit in the event of a working operation of the power tool, a second sensor that detects a second driving information corresponding to an output torque of the tool bit driven by the motor, and a controller connected to the first sensor and the second sensor for controlling the power tool. The controller is configured to calculate holding information corresponding to a holding force of a user to hold the tool body based on the first driving information and the second driving information and control the driving of the power tool based on the holding information.
Abstract translation: 能够以更高精度检测无意旋转的电动工具包括第一传感器，当第一传感器检测到当工具主体围绕工具头的纵向轴线旋转时与工具主体的动态运动状态相对应的第一驱动信息， 电动工具的工作操作，第二传感器，其检测对应于由电动机驱动的工具头的输出转矩的第二驱动信息;以及控制器，连接到第一传感器和第二传感器，用于控制电动工具。 控制器被配置为基于第一驾驶信息和第二驾驶信息计算与用户握持力对应的保持信息，并且基于保持信息控制电动工具的驾驶。
