Zusammenfassung:	The invention relates to a split fast-assembly slip directional moving type tube drawing bench. The pipe drawing bench mainly solves the problems that two slips of an existing pipe drawing bench clamp an oil pipe, the slips are easy to adhere and clamp on the oil pipe and cannot be separated when opened, and the carrying and mounting cost is high. The device is characterized in that the two hydraulic cylinders are connected with a linkage type hydraulic slip device; the linkage type hydraulic slip device comprises a hydraulic slip, an upper hydraulic slip base and a lower hydraulic slip base. The hydraulic slip base comprises a circular bottom plate and a cylindrical main body; a plurality of hydraulic slip telescopic rods are uniformly distributed and hermetically assembled on the outer circumference of the cylindrical main body; a hydraulic slip connecting ring is assembled on a clamping groove in the upper end of the hydraulic slip telescopic rod; a plurality of hydraulic slip connecting rods are arranged
