A dual-direction positioning device includes a main body, a first clamping structure, a second clamping structure, a first swing arm, a second swing arm, a coupling unit, and a first elastic element. The main body has a guiding trench portion. The first clamping structure and the second clamping structure are to and fro movably assembled to the guiding trench portion. The first swing arm is rotatably assembled on the first clamping structure and has a first engaging portion. The second swing arm is rotatably assembled on the second clamping structure and has a second engaging portion. The first engaging portion and the second engaging portion are rotatably assembled on the coupling unit and engaged with each other. The first elastic element has a first fixed end located between the first clamping structure and the second clamping structure and a first connecting end located on the first clamping structure. |

1. A dual-direction positioning device, for positioning a roll, the dual-direction positioning device comprising:
a main body, having a guiding trench portion; a first clamping structure, to and fro movably assembled to the guiding trench portion along a first moving direction; a second clamping structure, to and fro movably assembled to the guiding trench portion along a second moving direction, and the first moving direction being opposite to the second moving direction; a first swing arm, rotatably assembled on the first clamping structure, and the first swing arm having a first engaging portion; a second swing arm, rotatably assembled on the second clamping structure, and the second swing arm having a second engaging portion; a coupling unit, the first engaging portion and the second engaging portion being rotatably assembled on the coupling unit and engaged with each other within the coupling unit to have the first swing arm connecting to the second swing arm through the first engaging portion and the second engaging portion; and a first elastic element, having a first fixed end and a first connecting end, the first fixed end being located between the first clamping structure and the second clamping structure, and the first connecting end being located on the first clamping structure; wherein, when the first clamping structure moves along the first moving direction to drive the second clamping structure moves along the second moving direction by using the first swing arm and the second swing arm, the first elastic element generates an elastic recovery force to have the first clamping structure moves along the second moving direction and to have the second clamping structure moves along the first moving direction by using the first swing arm and the second swing arm so as to position the roll between the first clamping structure and the second clamping structure. |
