ABSTRACT:
A mechanism is composed of a seat, an air or oil cylinder, a connection seat, and a guide rod for maintaining the linear motion of a mechanical arm which is fastened with the connection seat. The guide rod is provided with a slot extending along the direction of the longitudinal axis of the guide rod. Two opposite walls of the slot of the guide rod are provided respectively with a rail enabling the guide rod to move linearly in conjunction with a plurality of rollers engageable with the rails. The axial positions of the rollers can be adjusted to correct the deviated motion of the guide rod.
