連結装置。 A drafting machine in which a bracket fixed to the upper end of a vertical rail is connected to a horizontal carriage that can freely run on a horizontal rail, and a drafting head that engages with the vertical rail is formed to be movable vertically and horizontally. A drawing machine in which a horizontal support shaft is provided on one side of a carriage and a bracket, and a groove-shaped open bearing is provided on the other, and the horizontal carriage and the bracket of the vertical rail can be freely engaged and detached, and the open bearing is provided. Pivotally attach the lever to the side of the horizontal carriage or bracket,
The distal end surface of the lever and the groove wall facing the distal end surface of the open bearing make pressure contact with the support shaft fitted into the open bearing, and the pivot position of the lever is located closer to the open bearing than the support shaft. The lever is displaced in the direction of the opening, and the distance between the rotation locus of the tip end face and the groove wall decreases from the pressure contact position toward the opening, and one side of the lever is attached with a spring or the like. It is characterized by being configured so that it can be pressed in the direction of the center of rotation by the biasing means, and a dead center can be set between the pressing position and the release position on the support shaft, so that it can be biased in both the pressing and releasing directions. Vertical rail connection device for drafting machines.
