The invention relates to the field of train compartment connecting devices, and discloses an automatic telescopic shear fork device which comprises a bottom plate assembly, a spring bolt assembly, a driving assembly and a shear fork assembly. The spring bolt assembly comprises a spring bolt and a spring bolt gear motor. The spring bolt is used for locking the through passage folding shed; the driving assembly comprises a driving motor, a screw rod and a sliding seat; an output shaft of the driving motor is in transmission connection with the lead screw, the lead screw is in threaded connection with a sliding seat, and the rotary motion of the lead screw is converted into linear motion of the sliding seat in the length direction of the lead screw; the sliding seat is further connected with a scissor fork assembly, and the scissor fork assembly is driven by the sliding seat to stretch out or retract. The shear fork assembly stretches out or retracts back to drive the through channel folding shed to stretch out or retract back. All the assemblies are installed through the bottom plate assembly, the shear fork driving assembly provides power and achieves limiting at the same time, so that the through channel folding shed is driven to stretch out and draw back to a certain position, and the position of the through channel folding shed is fixed through the spring bolt assembly to achieve locking.
