Abstract
A connection device for an apparatus includes a first rotation shaft, a second rotation shaft, a synchronization bulk, and a guide bulk. The first rotation shaft includes a first synchronization section set with a first groove; the second rotation shaft is in parallel with the first rotation shaft and includes a second synchronization section set with a second groove. The synchronization bulk includes a first end, a second end disposed opposite the first end, and a position limitation section, with the first end being disposed within the first groove and capable of sliding within the first groove, the second end being disposed within the second groove and capable of sliding within the second groove; the guide bulk being set with a first containing groove, a second containing groove, and a guide groove containing groove.
Claims9
A connection device, comprising:
- a guide bulk;
- a first rotation shaft rotatably received in the guide bulk;
- a second rotation shaft rotatably received in the guide bulk;
- a synchronization bulk movably received in the guide bulk and slidably clamped between the first rotation shaft and the second rotation shaft to cause the first rotation shaft and the second rotation shaft to rotate synchronously, wherein
- the first rotation shaft includes a first synchronization section set with a first groove;
- the second rotation shaft is disposed in parallel with the first rotation shaft and includes a second synchronization section set with a second groove;
- the synchronization bulk includes a first end, a second end disposed opposite the first end, and a position limitation section that connects the first end and the second end, with the first end being disposed within the first groove and capable of sliding within the first groove, and the second end being disposed within the second groove and capable of sliding within the second groove;
- the guide bulk being set with a first containing groove configured to contain the first synchronization section, a second containing groove configured to contain the second synchronization section, and a guide groove located between the first containing groove and the second containing groove and configured to contain the position limitation section so as to limit a movement direction of the position limitation section;
- and
- when the first rotation shaft and the second rotation shaft rotate, the first end of the synchronization bulk slides within the first groove, the second end of the synchronization bulk slides within the second groove, and the position limitation section slides within the guide groove, to cause the first rotation shaft and the second rotation shaft to rotate synchronously,
- wherein a length of the guide bulk in an axial direction of the first rotation shaft is equal to a length of the first groove and to a length of the second groove in the axial direction, respectively.
