PCB card transfer subrack

The invention relates to the technical field of PCB card processing, in particular to a PCB card transfer subrack, which comprises a transfer mechanism comprising a side plate and a beam part arranged on the side plate. According to the PCB card transfer subrack, the power part is started to drive the telescopic part to extend, the telescopic part drives the distance between the first transfer parts to be widened, so that the PCB card transfer subrack can transfer PCB cards of different models and thicknesses, the telescopic part extends and drives the second transfer part to contract at the same time, the second transfer part is folded, the space occupied by the second transfer part is reduced, and the space occupied by the second transfer part is reduced. When a PCB card with a small thickness needs to be transferred, the distance between the telescopic parts is narrowed similarly, meanwhile, the telescopic parts pull the second transfer parts to extend, and the distance between the second transfer parts is
