Carrying device

The embodiment of the utility model provides a carrying device. The carrying device comprises a rack, a crystal frame, a transmission assembly and a driving assembly. The crystal frame is movably connected to the rack, the crystal frame comprises a bearing cavity, and the bearing cavity is used for bearing a crystal bar; the crystal frame is connected with the driving assembly through the transmission assembly, and the driving assembly drives the transmission assembly, so that the crystal frame is switched between a first state and a second state under the action of the transmission assembly; in the first state, the axis direction of the bearing cavity is the first direction, in the second state, the axis direction of the bearing cavity is the second direction, and the first direction intersects with the second direction. Therefore, taking, placing and transferring of the crystal bars can be completed at a time through the carrying device, the processing technology of the crystal bars is simplified, transferr
