When the pushing ring moves, it will drive the push plate to rotate, and the push plate can drive the sliding seat to slide on the sliding rod, and then drive the movable rod and the clamping plate to move. When the four clamping plates are all in close contact with the end of the tetrafluoroethylene tube, the purpose of clamping and fixing the tetrafluoroethylene tube can be achieved. At this time, the staff no longer rotates the rotating ring. In this way, the tetrafluoroethylene tube can be quickly clamped and fixed, avoiding the situation that the tetrafluoroethylene tube is not firmly clamped due to the use of elastic structures such as springs, thereby improving the stability of the tetrafluoroethylene tube and preventing the tetrafluoroethylene tube from shaking or displacing during the processing process, which affects the processing efficiency. At the same time, the clamping process only requires rotating the rotating ring, making the operation process simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS
