Abstract: A clamp slide for use in a linear guide includes a slide body, two piston units disposed in the slide body, two elastic members stopped against the piston units, and two fluid pressure cylinders pushing the piston units to move toward a direction against restoring forces exerted by the elastic members. Further, a moveable member is disposed in each of the piston units and pushed by an inclined plane of a lateral cover to push a braking member, such that a rail is clamped by the left and right braking members. The lateral cover can be assembled in different ways according to actual needs for enabling the inclined plane to perform opposite tilt direction. As such, the clamp slide of the present invention has the effects of simplifying structure and reducing cost.
