[0023] There are two movable plates 5, and the two movable plates 5 are respectively threadedly connected to the two sections of the outer thread of the screw 4, and the two movable plates 5 are respectively located in two movable cavities 2 reserved in the processing base 1. The side walls of the movable plates 5 are attached to and slidably connected to the inner walls of the movable cavities 2 to ensure sufficient movable space for the movable plates 5, so that the pipe can be closed and clamped by the plug 9 after the movement of the movable plates 5.

[0024] The two side walls of the movable plate 5 are fixedly connected with protrusions 6, and the two protrusions 6 move inside the slide groove 7, and the slide groove 7 is connected with the movable cavity 2, so as to ensure the stability of the movable plate 5 in moving when the screw rod 4 rotates.
