The utility model relates to the technical field of blades, in particular to a high-abrasion-resistance chip breaking PCD blade which comprises a blade body, grooves are formed in the upper portion and the lower portion of the bottom of the blade body respectively, springs are installed in the grooves respectively, the height of the springs is larger than that of the grooves, and the diameter of the springs is matched with that of the grooves. According to the utility model, the defects in the prior art are overcome, the grooves, the springs, the heat conduction layer and the heat dissipation layer are arranged, the grooves are formed above and below the bottom of the blade, and the springs are arranged in the grooves, so that the springs can be compressed to move into the grooves when the blade is connected and mounted, and then when the blade is disassembled and assembled, the heat conduction layer and the heat dissipation layer are not damaged. Due to the fact that the spring recovers elasticity after bein
