The invention relates to a hollow tube-drawing machine and designs the machine according to the hydraulic principle to solve the problems such that the existing tube-drawing equipment is heavy, short in stroke and low in recovery rate. The hollow tube-drawing machine mainly comprises a top disc 1, a small cover plate 2, a sealing gasket 3, an outer hoop 4, a tertiary cylinder block 4, a tertiary cylinder block base 14, a secondary cylinder block 6, a secondary cylinder block base 15, a primary cylinder block outer ring 7, a primary cylinder block inner ring 8, a jacket 9, a lining 10, a sealing ring 11, a primary cylinder block base 12, a cavity 13, a main base 17, an oil transfer channel 16, oil transfer holes 19, and a quick connector 18. The hollow tube-drawing machine is light and speedy, convenient to move and simple to operate, allows valuable tubular objects to be recovered efficiently, easily and safely, allows labor to be less intensive for workers and helps improve labor efficiency.
