The invention relates to the technical field of construction machinery, and discloses a pressure-regulating type perfusion plugging machine. The pressure-regulating type perfusion plugging machine comprises a gearbox, a gear set, a hand-held motor, a cam rotating disc, a connecting rod, a movable pull rod, a piston rod, a piston copper sleeve, a material cylinder, a check-back device, a pressure gauge, a conveying pipe, a metal pipe, an avocado head, a bidirectional switch, a material receiving bottle, a fixing seat, an adjusting device, a limiting device, a supporting leg and a movable leg, wherein the gear set is movably installed inside the gearbox. According to the pressure-regulating type perfusion plugging machine, through the arrangement of the adjusting device, the effective movable distance of the piston rod in the piston copper sleeve is changed, so that the size of slurry discharged from the piston rod during one time of reciprocation is changed, the slurry discharging pressure is further changed,
