Abstract: The present invention discloses a deburring brush, comprising a pressing plate, jacking posts, copper sleeves, gaskets, guide posts, springs and bristle units. When the bristle units need replacement, it only needs to place the deburring brush on the ground and then press down edges of the front side of a top plate, so that all the bristle units will fall off against the suction force of strong magnets under the action of each jacking post. According to the present invention, it avoids being time consuming and labor intensive due to removing the bristle units one by one by using a screw driver or other similar devices while replacing the bristle units, and at the same time the replacing speed of bristles is greatly increased.
