The connecting component 2 includes a rotating sleeve 4. The rotating sleeve 4 is movably installed at the top of the connecting head 1. A screw groove 5 is formed inside the connecting head 1. At the bottom of the rotating sleeve 4 and penetrating through the top of the connecting head 1, a clamping foot 6 is installed. A first sealing pad 7 is filled at the bottom of the clamping foot 6, and a first sealing ring 8 is filled at the top of the clamping foot 6. A sealing cylinder 9 is installed at the bottom of the rotating sleeve 4 and located inside the screw groove 5.

[0023] In this embodiment, the screw groove 5 is threadedly connected to the syringe mouth. The sealing cylinder 9 is inserted into the inside of the syringe mouth and is set to be mutually matched. It is fixed by connecting the screw groove 5 with the syringe mouth. The sealing cylinder 9 is located inside the syringe mouth for further clamping connection.

[0024] In this embodiment, the side view of the clamping foot 6 is in an "丄" shape. The clamping foot 6 penetrates through the top of the connecting head 1 and is set to be movably rotatable. Through the clamping foot 6, the rotating sleeve 4 is connected to the connecting head 1 and can rotate, and the rotating sleeve 4 remains stationary when the connecting head 1 is rotationally connected.

[0025] In this embodiment, the sealing cylinder 9 is fixedly installed with the rotating sleeve 4. The outer diameter of the sealing cylinder 9 is smaller than the inner diameter of the screw groove 5. The syringe mouth is sealed by the first sealing pad 7 and the first sealing ring 8.
