The novel knuckle bearing of the hydraulic impact hammer comprises a hydraulic impact hammer body, a hammer core is arranged in the upper end of the hydraulic impact hammer body, a piston rod is arranged in the hammer core and penetrates through the interior of a mounting plate, and a drilling seat is mounted on the side wall of the lower end of the mounting plate. A piston rod is installed on the lower end of the mounting plate, the piston rod penetrates through the interior of the drilling seat, supporting seats are symmetrically installed on the side wall of the lower end of the mounting plate, a knuckle bearing is installed between the supporting seats, the piston rod is slidably connected to the interior of the knuckle bearing, and a sealing piece is connected to the lower end of the knuckle bearing. The joint bearing is additionally arranged at the joint of the hammer core and the piston rod, so that the piston rod can vertically fall and cannot deviate, and the piston rod is in sliding connection with
