A limit strip 8 is provided, and a limit groove 3 is provided on the injection head 2. The sizes of the limit groove 3 and the limit strip 8 are adapted to each other. The number of the limit groove 3 and the limit strip 8 is four, which are arranged in a circle respectively. The limit strip 8 is located inside the limit groove 3. The fastener 6 cooperates with the thread 5 during the rotation process and can gradually move inward. Through its continuous movement, the fastening notch 7 can be contracted. The mounting tube 4 is fixed to the injection head 2 through the fastener 6, and then the sealing balloon 11 is placed in the rectum, and the push rod of the syringe 1 is pushed. The gas is injected into the inside of the sealing balloon 11 through the catheter 10. It can be expanded by gas injection.

When the limiting strip 8 is completely moved to the interior of the limiting groove 3, the pushing of the installation tube 4 is stopped, and the fastener 6 is rotated at this time. The fastener 6 cooperates with the thread 5 during the rotation process and can gradually move inward. Through its continuous movement, the fastening notch 7 can be contracted, and the installation tube 4 is fixed to the injection head 2 through the fastener 6, and then the sealing balloon 11 is placed in the rectum, and the push rod of the syringe 1 is pushed. The gas is injected into the interior of the sealing balloon 11 through the catheter 10, and it can be expanded by gas injection. When the patient cannot control it by himself, it can at least be expanded through the sealing balloon 11 to avoid overflow of the filled liquid.
