摘要： A control system is provided for use in a power tool. The control system includes: a rotational rate sensor having a resonating mass and a controller electrically connected to the rotational rate sensor. The rotational rate sensor detects lateral displacement of the resonating mass and generates a signal indicative of the detected lateral displacement, such that the lateral displacement is directly proportional to a rotational speed at which the power tool rotates about an axis of the rotary shaft. Based on the generated signal, the controller initiates a protective operation to avoid further undesirable rotation of the power tool. The controller may opt to reduce the torque applied to shaft to a non-zero value that enables the operator to regain control of the tool.

摘要： A mechanism (300) for connecting a chuck (390) to a spindle (320) is disclosed. The mechanism (300) includes an element (450) that secures the chuck (390) to the spindle (320), an element (450) that allows torque to be transferred from the spindle(320) to the chuck(390), and an element (382, 386) that ensures that the rotational axis of the chuck is aligned with the rotational axis (50) of the spindle (320). The connection mechanism (300) also includes a feature (350) that enables the connection end (312) of the tool accessory (310) to be inserted into the chuck (390) past portion of the connection mechanism (300). The portion of the tool accessory (310) that extends past the connection mechanism (300) represents a net shortening of the total length (figure 1) of the tool which is defined as the total length from the back of a tool (1) to the tip of the tightened tool accessory (310).
摘要翻译：公开了一种用于将卡盘（390）连接到主轴（320）的机构（300）。所述机构（300）包括将卡盘（390）固定到主轴（320）的元件（450），允许扭矩从主轴（320）传递到卡盘（390）的元件（450），以及确保卡盘的旋转轴线与主轴（320）的旋转轴线（50）对准的元件（382,386）。连接机构（300）还包括能够使工具附件（310）的连接端（312）经过连接机构（300）的部分插入到卡盘（390）中的特征（350）。延伸穿过连接机构（300）的工具附件（310）的部分表示工具的总长度（图1）的净缩短，其被定义为从工具（1）的后部到拧紧的工具附件（310）的尖端。
