The working principle of the present invention is described as follows:
as shown in fig. 1 and 2, first, the second screw cap 1 and the scissors-shaped connecting rod 2 are inserted into the lumen of the PE tube, and since the second cylinder 3 is sleeved on the second threaded rod 8, the first cylinder 4 is screwed and moves close to the second screw cap 1, and at this time, under the pushing of the first cylinder 4, the second cylinder 3 also moves close to the second screw cap 1, so that the scissors-shaped connecting rod 2 becomes an open state and abuts against the inner tube wall of the PE tube; then, the position of the connector body 5 in the first through hole 29 of the vertical arm is adjusted, so that the cutter head 20 abuts against the outer pipe wall of the PE pipe, at this time, the handle 12 is rotated, the cutter head 20 makes a circular motion around the outer pipe wall of the PE pipe, and at the same time, the cutter head also makes a linear motion along the axis of the PE pipe in the direction away from the PE pipe, and the handle 12 stops rotating after the cutter head 20 exits from the outer pipe wall of the PE pipe, so that the scraping is completed. In the process that the cutter head 20 scrapes the outer wall of the PE pipe, when the pipe wall becomes thick, the cutter head 20 drives the first cylinder 19, the second cylinder 18 and the fixed block 16 to jump up along the radial direction of the PE pipe in the direction far away from the outer wall of the PE pipe, in the process, the upper bottom surface of the first cylinder 19 extrudes the spring 27, and the spring 27 contracts; when the pipe wall becomes thin, the contracted spring 27 gradually expands, the lower end of the spring 27 extrudes the upper bottom surface of the first cylinder 19, and the first cylinder 19 drives the cutter head 20, the second cylinder 18 and the fixed block 16 to fall back towards the outer pipe wall of the PE pipe along the radial direction of the PE pipe until the cutter head 20 abuts against the outer pipe wall of the PE pipe.
When the pipe wall thickness size of the PE pipe after scraping has the requirement, the pipe wall thickness after scraping is the same, only need to mention the fixed block 16, the fixed block 16 will drive the second cylinder 18, the first cylinder 19 and the tool bit 20 to move along the radial direction of the PE pipe to the direction far away from the pipe wall outside the PE pipe, the spring 27 contracts until the upper end of the tool bit 20 is abutted against the first side surface 22 of the horizontal arm of the tool rest body, at this moment, the fixed block 16 is rotated to make the first limiting block 15 abutted against the top surfaces of the two second limiting blocks 17, thereby locking the position of the tool bit 20, making the tool bit 20 not bounce along with the thickness change of the pipe wall any more, thus, the pipe wall thickness of the PE pipe after scraping can be guaranteed to be the same.
