A PE pipe clamping device according to claim 8, characterized in that: A telescopic rod (9) is fixedly arranged at the top of the slot (10), and the bottom end of the telescopic rod (9) is fixedly connected to the movable rod (2). A second rubber pad (625) is fixedly arranged at the bottom of the arc block (624), and a first rubber pad (44) is fixedly arranged inside the positioning block (43). The size of the first rotating shaft (42) is smaller than the size of the threaded end of the tensioning screw (41), and the size of the first rotating shaft (42) is the same as that of the positioning block (43).

10. The method for using the PE pipe clamping device according to claim 9, characterized in that: The following steps are involved: Step 1: Adjust the depth of the movable rod inserted into the fixed rod, and by tightening the tension screw, the fixed rod and the movable rod can be fixed under the action of the first rubber pad, so as to facilitate the adjustment of the height of the ring; Step 2: Insert the PE tube between the two ferrules, tighten the adjusting screw, the adjusting screw drives the arc block to move downward, the arc block drives the second rubber pad to move downward, and then the PE tube is supported and fixed; Step 3: When the PE pipe is fixed, the first electric push rod is started to extend, and the first electric push rod drives the block to move downward, and the block enters the square hole. The first pressure sensing sheet senses the pressure to control the extension of the first electric push rod, and the block is stuck in the square hole to fix the nut; Step 4: When the PE pipe is against and fixed, start the second electric push rod to extend, and the second electric push rod drives the limit cover to move. The limit cover is set on the end of the PE pipe. The second pressure sensing sheet senses the pressure to control the extension of the second electric push rod. The limit cover is against the end of the PE pipe to limit and fix the PE pipe in the horizontal direction.
