[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model uses an inflatable ball, a first air pipe, a control box, a second air pipe, a pressurizing bag, a rubber pad, a lifting cylinder, a pressure plate, a pressure sensor, and a ring light in coordination. The inflatable ball is inflated, and the gas enters the control box from the first air pipe, and then enters the pressurizing bag from the second air pipe. The gas pressure in the control box increases, and the rubber pad is pushed to move along the lifting cylinder to change the distance the lifting tube extends. The pressure in the control box is judged by the scale line. When the pressure is too low, the lifting cylinder moves downward to make the pressure plate press the upper pressure sensor. When the pressure is too high, the lifting cylinder moves upward to make the rubber pad press the lower pressure sensor. The ring light is connected to the pressure sensor circuit to indicate the pressure situation, and can monitor the air pressure in the pressurizing device in real time, and can send out a light prompt when the pressure is too high or too low.

[0013] 2. The utility model also uses a threaded rod, a blocking block, a control box, a spring, a connecting piece, a sliding rod, and a pressurized bag. By connecting an air pumping device to the threaded rod, the air pumping device pushes the blocking block into the control box, so that the interior of the control box is connected to the air pumping device. After the air pumping device is disassembled, the spring pushes the connecting piece to move along the sliding rod, so that the blocking block blocks the interior of the threaded rod to prevent air leakage, thereby replenishing pressure for the pressurized bag.
