ABSTRACT:
A fixing device for fixing a workpiece defining a hole, includes a fixing shaft, a sliding bar, and a sliding block. The fixing shaft is configured to be inserted in the hole of the workpiece and defines a groove therein along an axial direction thereof. The sliding bar is mounted to the fixing shaft and movable in the groove along the axial direction. The sliding block is mounted to the fixing shaft and movable in the groove along a radial direction of the fixing shaft. When the sliding bar moves forward along the axial direction, the sliding block is moved toward the sliding bar along the radial direction. When the sliding bar moves backward along the axial direction, the sliding block is driven to move away from the sliding bar along the axial direction to urge against a wall bounding the hole of the workpiece to fix the workpiece.
