Hydraulically-driven telescopic pallet fork

The utility model relates to a hydraulically-driven telescopic pallet fork which comprises a pallet fork body, at least one oil cavity is machined in the front end of the pallet fork body, corresponding cylinder rods are movably installed in the oil cavities through corresponding pistons respectively, and cylinder rod guide sleeves are installed at the front ends of the oil cavities respectively in a sealed mode. Two hydraulic oil ways are machined at the rear end of the fork body, one hydraulic oil way is connected with the rod end of the oil cavity, and the other hydraulic oil way is connected with the rodless end of the oil cavity. The front end of the pallet fork body is sleeved with a pallet fork sleeve, and the front end of the pallet fork sleeve is fixedly connected to the front endof the cylinder rod. On the basis that the weight and the out-of-load distance of the whole pallet fork are not excessively increased, the advantages of being light in structure and convenient to stretch and retract can be e
