A lifting rod assembly with a coolant supply and pressurizing device includes a pipe with an inner passage. The inner passage includes an open input end, an open output end, and an input section and an output section sequentially arranged from the open input end toward the open output end. The output section is in communication with the output end. In the inner passage is movably disposed a slider which is provided with a plurality of pressure flutes, each of the pressure flutes has a diameter smaller than the diameter of the input section, and both ends of the slider are provided with a plurality of buffers, a band saw of a band saw machine is allowed to insert in the output end of the lifting rod assembly, and the slider is abutted against the band saw. |
