Abstract: A machine tool includes a receptacle extended from a stand, a working spindle rotatably attached to the receptacle and having a chuck device for grasping and releasing a tool member from the working spindle, a follower slidably attached onto the working spindle for actuating the chuck device to selectively grasp or release the tool member, a lever arm having one end pivotally attached to the receptacle with an axle, an actuator attached to the lever arm for actuating the follower to operate the chuck device to grasp and to release the tool member, and a driving device includes a piston for moving the lever arm and the actuator to actuate and move the chuck device to release the tool member.

Abstract: A machine tool includes a lever arm extended from a column, a working spindle and a guiding member attached to the lever arm and having an upper guiding surface and a lower recess formed by an anchoring surface, the guiding surface is located farther away from the column as compared with the anchoring surface of the guiding member, a tool cartridge is attached to the lever arm for supplying tool elements to the working spindle, and includes a seat having a cam surface, a guiding roller attached to the seat for engaging with the guiding surface of the guiding member and for selectively separating the tool cartridge from the working spindle and the guiding member.

Abstract: A fastening device includes a mounting sheet which is adapted to have a lower major wall surface thereof secured to and overlying a platform of a vehicle. A plurality of fastening members are disposed on the upper major wall surface. Each fastening member includes a connecting portion secured on an upper major wall surface of the mounting sheet, and an anchoring portion which includes a proximate end hinged on the connecting portion and a distal end disposed opposite to the proximate end so as to be turnable to be normal to the upper major wall surface. As such, a rope is adapted to pass through the anchoring portions of selected ones of the fastening members to tense the rope for tightening any shape and size of goods on the mounting sheet.
