A parallel fence includes a fence body, a front guide, a rear guide, and a positioning device. The fence body is adapted to be placed on a worktable. The front guide and the rear guide are disposed on the front end and the rear ends of the fence body. In a first operational position, the front and rear guides are fixed in position relative to the front and rear guides. In a second operational position, the front and rear guides are prevented from being removed from the front and rear rails in a first direction upwardly away from a surface of the worktable, but the front and rear guides are permitted to move in a second direction along the length of the front and rear rails. In a third operational position, the front and rear guides are permitted to be removed from the front and rear rails in the first direction.
