Abstract: The present utility model provides an operation table with a telescopic table board positioned with an eccentric rocker. The operation table includes a table board and support feet, the support feet being positioned at both ends of the table board along the length direction.

Abstract: A support device includes two beams secured on top of a base and two bolts rotatably received in the beams. Two slides are slidably engaged in the beams and engaged with the bolt and for allowing the bolt to move the slide along the beam when the bolt is rotated. Two seats are secured to the slides and two brackets are pivotally coupled to the seats for supporting a plate. One or both of the brackets include a fastener for engaging with either of the orifices and for securing the plate and the brackets to the seats at various angular positions.

Abstract: A gripping device including a fixture having a working surface and at least one hole. A stop rises above the working surface of the fixture. A threaded fastener is provided to screw into the at least one hole in the working surface of the fixture. A gripping member is provided such that a work piece can be held in a stationary fashion between the gripping member and another element such as a stop. The gripping member includes a conical bore and an elongated bore. The elongated bore is a through bore in that it extends through the entire thickness of the gripping member. The conical bore extends through only a portion of the thickness of the gripping member. The fastener extends through both the conical and elongated bores. The elongated bore is offset towards the gripping face of the gripping element thereby enabling the gripping member to travel to an from the work piece a greater distance than gripping members employing a centrally located circular through bore.

Abstract: A device (10) for centering and guiding strip material (12) into a punch press (16) which device (10) is adjustable to accept different widths of strip material (12) and which grasps the strip material (12) during the punching operation. The device (10) includes a pair of parallel guide members (24, 26) mounted to a pair of slide members (28, 30) which are coupled to move in opposite directions. The slide members (28, 30) are adjustable to vary the space between the guide members (24, 26) and are actuated by an actuating rod on the press (16) to close down the space between the guide members (24, 26) when the press (16) is down during the punching operation to grasp the strip material (12) between the guide members (24, 26).
