Abstract:
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, the first swing arm having a first engaging portion, and the first swing arm rotatable about the first engaging portion; a second swing arm, rotatably assembled on the second clamping structure, the second swing arm having a second engaging portion, and the second swing arm rotatable about the second engaging portion; a coupling unit, the first engaging portion and the second engaging portion being rotatably assembled and disposed on the coupling unit, the first engaging portion and the second engaging portion matingly engaged with each other 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 disposed on the first clamping structure; wherein, when the first clamping structure moves along the first moving direction to drive the second clamping structure, 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 make the first clamping structure move along the second moving direction and to make the second clamping structure move 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.
