。[Claims for Utility Model Registration] 1. A second rolling element that is integrated with the first rolling element, wherein first and second moving bodies that move in opposite directions are arranged in contact with the first rolling element. arranging third and fourth moving bodies that move in opposite directions in contact with the
Workpiece attachment members are attached to the tips of the first, second, third, and fourth moving bodies, arranged at equal intervals, and a driving body is connected to one of the moving bodies, so that the driving body operates. Accordingly, the movement of one of the driving bodies causes transmission to the other moving bodies via the first and second rolling bodies, and opens and closes the pitches while maintaining the same pitch of each moving body. A pitch opening/closing mechanism characterized in that the driving body is provided with a mechanism for varying the stroke of the driving body. 2 The first rolling element is a pinion having a certain number of teeth, the first and second moving bodies are racks,
The second moving body integrated with the first rolling element is a pinion having three times the number of teeth, and the third and fourth moving bodies are similarly two racks, each rack being parallel to each other. It constitutes a part of a moving plate, one end of the plate is bent at right angles and arranged at equal intervals, the driving body is a cylinder, and as the cylinder moves, the rack of one plate is bent. The pitch opening/closing mechanism according to claim 1, wherein the pitch opening/closing mechanism is such that the movement is transmitted to other plate members via the pinion, and the pitch is opened/closed while maintaining an even pitch.
