The invention discloses a steering pipe column. The steering pipe column comprises an upper pipe column component (100), a lower pipe column component (200), a mounting bracket (300), cutting blocks (500) and an energy-absorption steel belt (600), wherein the mounting bracket (300) is fixedly connected with the upper pipe column component (100), and the mounting bracket (300) is fixedly connected with the lower pipe column component (200) or a vehicle main body through the cutting blocks (500); one end of the energy-absorption steel belt (600) is fixed relative to the lower pipe column component (200) or the vehicle main body, the other end of the energy-absorption steel belt (600) is bent to penetrate through a via hole (301) and a guide groove (302) in the mounting bracket (300). When the steering pipe column collides with a human body, and the cutting blocks are fractured due to impact energy, the upper pipe column component and the mounting bracket make crumple movement along the axis of the steering pipe column, relative to the lower pipe column component, so that the energy-absorption steel belt can be pulled straightly so as to perform plastic deformation and energy absorption. The steering pipe column disclosed by the invention is a crumple type energy-absorption steering pipe column, and has the advantages of being light in weight, being simple in structure, having a good energy-absorption effect, and being easy to quantize the energy-absorption capability.
