Abstract
The utility model discloses precision flat tongs which comprise a base, a left jaw and a right jaw. A guide rail is arranged on the base, and a fixed end sliding block and a movable end sliding block are arranged on the guide rail in a sliding mode. A fixed end sliding base is connected to the fixed end sliding block, and a movable end sliding base is connected to the movable end sliding end. The precision flat tongs improve the stress bearing situation of a workpiece, and the workpiece is prevented from only bearing the horizontal force. Besides, under the joint effect of the inclined end face of a top block and an inclined right side face of a first boss, the workpiece further bears downward friction force to be attached to the base, and the workpiece further cannot warp up. In addition, due to the fact that the height of the clamping point is closer to the workpiece, clamping is more reliable.
