A balloon pressure pump comprising a cavity (1) having a distal end and a proximal end a push rod (2) having a distal end and a proximal end, and provided with an external thread and inserted into the cavity a handle (3) fixedly connected with the proximal end of the push rod (2) a locking member (4) having a distal end and a proximal end and arranged on the proximal end of the push rod (2) and used to lock same the distal end of the locking member (4) is fixedly connected with the proximal end of the cavity (1). The handle (3) is internally provided with a sleeve (5) to accommodate the push rod (2) said sleeve (5) is fixedly connected with the proximal end of the locking member (4). The proximal end of the push rod (2) includes a spring (11) which is enclosed within the sleeve. The simple structure of the pump simplifies operations such as pressure application, pressure relief, negative pressure evacuation and the like, and is greatly convenient for a user.
