作业工具
摘要：
本发明提供一种作业工具，在手柄能够相对于主体部移动的作业工具中，使作业工具的结构紧凑。锤钻(100)具有主体部(101)与手柄部(109)。主体部具有马达外壳(103)与齿轮外壳(105)。手柄部具有手柄前侧部分(161)与手柄后侧部分(162)。手柄前侧部分罩住马达外壳，能够相对于主体部在锤头(119)的轴线方向上移动。在马达外壳上设置有突起部(103a)，该突起部在锤头的轴线方向上贯穿手柄前侧部分。该突起部隔着垫圈(171)与螺钉(170)螺纹配合。该垫圈与螺钉配置于手柄前侧部分与手柄后侧部分之间，通过使该垫圈及螺钉与手柄前侧部分的凸缘部(161b)相抵接，来限定手柄部的后方位置。
摘要（英）：

A power tool includes a motor, a driving mechanism, a body housing, a handle, and a rear position defining member. The driving mechanism is driven by the motor and configured to drive a tool bit in a longitudinal direction. The body housing houses the motor and the driving mechanism. The handle is connected to the body housing so as to be allowed to move with respect to the body housing between a front position and a rear position in the longitudinal direction, while being biased by a biasing member in the longitudinal direction. The handle includes a handle base and a handle cover. The rear position defining member extends from the body housing to a position between the handle base and the handle cover in the longitudinal direction and is configured to define a rear position of the handle.
