The invention relates to the technical field of medical instruments and discloses leg sleeve connecting equipment of air pressure wave therapeutic equipment. The leg sleeve connecting equipment comprises four air bags, wherein the four bags are as long as the thighs, a joint air pipe is mounted in the air bags and penetrates through the four air bags, a pressure device is connected with the left side of the joint air pipe, and a movable hole is formed in the top of the joint air pipe. According to the leg sleeve connecting equipment of the air pressure wave therapeutic equipment, one joint air pipe penetrates through all the air bags, during using, air inflation starts from the left side of the joint air pipe, pressure of the left side of a piston becomes large, the piston starts to move rightwards, when the piston passes through the position below the movable hole, a movable rod is pushed to move upwards, at the moment, a first air hole and a second air hole are tightly attached, meanwhile, an opening in the lower part of the second air hole is moved out of a base sleeve, an opening in the upper part of the first air hole is moved to the position above a mounting table, therefore, a left cavity of the joint air pipe is communicated with the air bags, air is poured into the air bags, and the piston is not pushed to move by airflow any longer due to the fact that a vent port for the airflow is found.
