The invention discloses a hydraulic oil cylinder with a buffering function. The hydraulic oil cylinder comprises a cylinder barrel, a cylinder cover is fixedly connected to the top end of the cylinderbarrel, a piston rod is arranged in the cylinder barrel, the outer side of the bottom end of the piston rod is fixedly sleeved with a piston, a buffer column is arranged at the top end of the piston,the outer side of the piston rod is fixedly sleeved with a buffer column, the buffer column is fixedly sleeved with a first buffer sleeve, and a top guide block is arranged at the top end of the inner wall of the cylinder barrel. According to the invention, the first buffer sleeve and a first buffer groove are arranged to effectively reduce the propelling speed of the piston rod and the piston; asecond buffer sleeve and a second buffer groove are arranged to reduce the contraction speed of the piston rod; a pressing block and a buffer block are arranged to cooperate with the second buffer sleeve for buffering; the buf
