Claims

[Scope of utility model registration request]

An upper rail with elongated holes in the left and right horizontal directions is fixed near both ends of the front and rear frame rods of a pedestal equipped with leg plates of an appropriate height in a symmetrical position, and a pair of casters are provided on the front and rear lower surfaces, respectively. A lower rail is fixed to the front and rear ends of each of the left and right base plates, facing downwardly from the upper rail and having an elongated hole parallel to the elongated hole, and the upper rail and the lower A roller at the other end of a cross link having one end pivotally supported by the rail is fitted into each of the elongated holes located above and below, and each leg of a pair of left and right arms is attached to a long shaft on which the front and rear opposing rollers are pivotally supported. The inner ends of these arms are pivotally supported by a crank pin at one end of the operating shaft which is pivotally supported approximately in the middle of the cutting pedestal by loosely fitting the ends thereof, and the operating shaft is rotated in the same direction by a movement of the pedal to one side. A device for launching and moving an article, characterized in that the angle formed by the cross link is changed by rotating the article intermittently in the direction of the arrow.
