A first inclined plane, two second inclined planes and two third inclined planes are arranged on a multi-inclined-plane tip of the five-inclined-plane needle tube, the first inclined plane has a first inclination angle of 9 degrees +/-2 degrees relative to a central axis, and the first rotation angle of the first inclined plane is 0 degree; the multi-slope tip is characterized in that the two second slopes serve as main cutting faces, extend from the base to the tip of the multi-slope tip and are symmetrically arranged, the two second slopes intersect at the tip to form a second ridge with a needle tip, and each second slope has a second inclination angle of 12 degrees +/-2 degrees and a second rotation angle of 45 degrees +/-5 degrees; the two third slopes are located in the middle of the multi-slope tip and are symmetrically arranged, each third slope intersects with the corresponding second slope to form a third ridge, and the third slopes are located on the outer sides of the second slopes. The third incl
