The utility model relates to the technical field of hydraulic power tongs, in particular to a novel hydraulic power tong braking mechanism which comprises a hydraulic cylinder body 1, a plurality of sets of brake block grooves 5 are formed in the inner wall of the hydraulic cylinder body 1, brake blocks 6 are movably connected in the brake block grooves 5 in an inserted mode, and push-pull springs 8 are fixed to the ends, stretching into the brake block grooves 5, of the brake blocks 6. A push-pull rod 12 is fixed to the other end of the push-pull spring 8, a pressing plate 11 is fixed to the other end of the push-pull rod 12, a button 3 is fixed to the other end of the pressing plate 11 and movably inserted into a button hole 2, and the button hole 2 is formed in the outer wall of the hydraulic cylinder body 1. The novel hydraulic power caliper has the beneficial effects that when the novel hydraulic power caliper needs to be braked, an upper set of buttons and a lower set of buttons are pressed down at the
