Abstract (en)

The present disclosure provides a tensioning device for tensioning a wire (10). The tensioning device includes:a frame body (100); a slider (300) slidably mounted onto the frame body (100); a roller (400) rotatably mounted onto the slider (300) and configured to tension the wire (10) thereon; and a spring (600) compressed between the slider (300) and the frame body (100). The spring (600) pushes the slider (300) to move in a direction to tension the wire (10) to increase a tension force on the wire (10) when the tension force on the wire (10) is less than a predetermined minimum tension force; the slider (300) will move in a direction to loosen the wire (10) against the pushing of the spring (600) to reduce the tension force on the wire (10) when the tension force on the wire (10) is greater than a predetermined maximum tension force. Therefore, the tension force on the wire (10) can be controlled within a reasonable range, effectively avoiding the problem that the wire (10) cannot be transported result from the wire (10) slipping on the roller (400) due to a too small tension force or the wire (10) being pulled to be broken due to an excessive tension force, thereby ensuring a normal transportation of the wire (10).
