The invention relates to the technical field of underground drilling wireless transmission, in particular to a hydraulic pulse generator for drilling. Two vertically symmetrical fixing plates are fixedly connected to the two side faces of a barrel, each fixing plate is hollow, a rotating rod movably penetrates through the right side face of each fixing plate, a threaded sleeve is rotationally connected to the lower surface of each fixing plate through a bearing, and each rotating rod is in transmission connection with the corresponding threaded sleeve. A threaded shaft is in threaded connection with the interior of the threaded sleeve and movably connected with the motor in an abutting mode. The bottom end of the threaded shaft is fixedly connected with an anti-skid plate, and the end, away from the threaded shaft, of the anti-skid plate is fixedly connected with an anti-skid pad. In order to solve the problem that vibration can be generated when the motor works, a motor stabilizing device is arranged, an ant
