The invention discloses a steering pipe column telescopic structure and a steering pipe column assembly adopting the steering pipe column telescopic structure. The steering pipe column telescopic structure comprises an upper mounting bracket fixed to a vehicle body, and a pipe column bracket fixed to a steering pipe column, wherein the middle section of the upper mounting bracket protrudes, and the left section and the right section of the upper mounting bracket are flat and straight; the pipe column bracket is in a U shape, and support lugs respectively stretch out from the left side and the right side of the pipe column bracket; the left section and the right section of the upper mounting bracket are respectively fixed to the support lugs through a shearing block; a slide groove hole is formed in the middle section of the upper mounting bracket, and a slide groove bolt penetrates through the slide groove hole and is fixed in a threaded hole correspondingly formed in the U-shaped bottom of the pipe column bracket. After the steering pipe column confronts a collision, the shearing blocks are fractured, and the steering pipe column drops down with the pipe column bracket; however, because the slide groove bolt makes a sliding limit effect in the slide groove hole, the steering pipe column cannot thoroughly drop down.
