摘要： A liner for a power tool holder has a wall which defines an interior and an exterior periphery. The interior periphery is sized to receive a tool shaft and the exterior periphery is sized to fit within a tool holder. The liner protects the tool shafts from marring, nicking or the like while being frictionally held by the tool holder.

摘要： A resecting tool contains a rotatable chuck inside a base for engaging the drive shaft of a motor. The chuck extends into a tubular casing that has an outer actuator sleeve. The sleeve is limited to rotation relative to the casing and is used to move a pair of locking elements or balls in separate helical slots in the casing. Each ball is seated in a collar that abuts a collet receiver inside the casing. During implement changeover, the collar abuts the collet receiver and acts as a brake to prevent accidental actuation of the chuck of the tool. The collet receiver is spring-biased into contact with a first collet which closely receives a tool implement within the resecting tool. The sleeve is used to manipulate the collet to clamp onto and unclamp the tool implement. A collet coupling is located on the front end of the casing and has a collet nut on its forward end. The collet nut houses a second collet with a serpentine cut for engaging and retaining a guide sleeve for supporting the tool implement. Both collets are designed to engage and lock onto tool implements and guide sleeves at variable distances along their axial lengths.
摘要翻译：切割工具在基座内包含可旋转卡盘，用于接合马达的驱动轴。卡盘延伸到具有外致动器套筒的管状外壳中。套筒被限制为相对于壳体的旋转，并且用于将一对锁定元件或球移动到壳体中的分开的螺旋槽中。每个球都坐在一个与套管内的夹头接收器相邻的轴环上。在工具切换期间，套环与夹头接收器邻接，并用作制动器，以防止意外致动工具的卡盘。夹头接收器被弹簧偏置成与第一夹头接触，第一夹头紧密地接收在切割工具内的工具。套筒用于操纵夹头以夹紧和松开工具。夹头联接器位于壳体的前端，并在其前端具有夹头螺母。夹头螺母装有一个具有蛇形切割的第二夹头，用于接合和保持用于支撑工具的导向套筒。两个夹头均设计成沿着其轴向长度可变距离地接合和锁定工具和导向套筒。

摘要： A plunger type rotary chuck assembly includes a main seat in which bearings are mounted for rotatably supporting a main shaft. An inner periphery of an axial hole of the main seat includes a number of fluid passages A number of piston chambers are provided around and communicated with the axial hole of the main seat. Piston rods are mounted in the piston chambers and coupled to discs that urge clutches or a follower ring to move a spring chuck. The spring chuck includes an outer inclined surface that may disengage from or engage with an inner inclined surface of the main shaft or of the follower ring, thereby allowing the spring chuck to release or hold a work piece to be processed.
