Variable-pitch clamping type pallet fork device

The invention discloses a variable-pitch clamping type pallet fork device. The device comprises a base plate, a telescopic driving mechanism, a variable-pitch driving mechanism and two symmetrically-arranged telescopic fork mechanisms, wherein the telescopic driving mechanism, the variable-pitch driving mechanism and the two symmetrically-arranged telescopic fork mechanisms are arranged on the base plate; the variable-pitch driving mechanism is used for simultaneously driving the two telescopic fork mechanisms to relatively move left and right on the base plate so that goods can be clamped between the two telescopic fork mechanisms; and the telescopic driving mechanism is used for simultaneously driving the two telescopic fork mechanisms to extend forwards and then retract or continuously extend backwards after retracting on the base plate so as to drive the clamped goods to be transferred forwards and backwards. The device has the advantages of being simple and compact in structure, convenient and fast to ma
