[0012] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0013] (1) The bottom of the machine body is provided with an opening structure. The opening structure can absorb the circular waste pieces cut out by the cooperation between the movable belt and the magnetic suction block, and the circular waste pieces can be quickly removed by pulling the hole opener backwards to prevent the waste pieces from getting stuck inside the hole opener after being cut, affecting the secondary use. It takes a certain amount of time to clean up the waste pieces. The hole opener is provided with a limit block inside. The limit block cooperates with the magnetic suction block to absorb the iron waste pieces knocked out, preventing the iron waste pieces from falling into the pipe during the drilling process and affecting the use of the pipe. After magnetic suction, The user only needs to push the hole opener forward to drive the gear to control the movement through the toothed plate to eject the waste sheet from the discharge chute, so that it can be quickly reused without worrying about the problem of card. The sliding bar on the top of the hole opener is provided with a push-back block, which allows the user to control the hole opener to press down to open the hole more stably without loosening. The outer wall of the hole opener is also provided with a grinding circle. Burrs will be generated at the opening of the pipe after cutting.

The V-shaped clamp can better fit the outer wall of the pipe. The support structure can also be quickly disassembled through the cooperation between the fixed rod and the movable rod. After cutting, the user can rotate the threaded barrel to separate the fixed rod, and then rotate the movable rod to rotate the clamp and the base to open, so that the main board can be quickly removed from the pipe, which speeds up the user's work efficiency.

[0015] (3) An auxiliary structure is also provided on the main board. The auxiliary structure is used to fix the auxiliary support structure when drilling holes, so as to ensure the balance of the supports on both sides of the hole opener and avoid that only one side is clamped and fixed while the other side lacks support force during cutting, which causes the user to press the hole opener hard to produce a tilt deviation, resulting in problems such as change in the hole opening position, tilt, and displacement. The auxiliary structure can freely control the up and down distance through the slider, and the two auxiliary arms can be opened in a herringbone shape to form a stable triangular support force. The arc plate at the bottom of the auxiliary arm can be rotated and stored. After opening, it can also fit the outer walls of pipes of various sizes. When not in use, it can also be controlled to reverse through the rotating seat to reduce the occupied area to form a folding storage function. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] A horizontal plate is provided on the top of the fixed rod 605 and the movable rod 607, a threaded rod 604 passes through the top of the horizontal plate, a rotary handle 601 is provided on the top of the threaded rod 604, a holder 602 is rotatably provided at the bottom of the threaded rod 604, and a V-shaped anti-slip groove is provided at the bottom of the holder 602 and the top of the base 603.

[0036] The auxiliary structure 2 includes a slide rail 201 , the back of which is fixedly connected to the front of the main board 4 , a rotating seat 203 is slidably provided on one side of the slide rail 201 , and a slider 202 is rotatably provided on one side of the rotating seat 203 .

[0037] A fixing screw penetrates the top of one side of the slider 202 , and auxiliary arms 204 are rotatably provided at the front and rear sides of the bottom of the slider 202 , and an arc plate 205 is rotatably provided at the bottom of the auxiliary arm 204 .

[0038] The working principle and use process of the present invention are as follows: when in use, the user first places the base 603 at the bottom of the pipe to be cut, and then rotates the base 602 to the top of the pipe with the rotating connection with the movable rod 607 as the center of the circle. After the displacement, the split fixing rod 605 will form a closed state. At this time, the threaded sleeve 606 can be rotated to close the fixing rod 605 together through the threaded sleeve 606, and then the threaded rod 604 is rotated. The threaded rod 604 drives the base 602 to move downward along the movable rod 607 and the fixing rod 605 to clamp and fix the pipe. After the base 602 and the base 603 are set, the slider 202 on the other side of the slide rail 201 is loosened, and the fixing screw is loosened when loosened. After loosening, The two auxiliary arms 204 are rotated and opened in a herringbone shape with the rotating connection with the slider 202 as the center. After the auxiliary arms 204 are opened, the arc plate 205 at the bottom will flip open, and finally the rotating seat 203 is slid downward. The rotating seat 203 drives the slider 202 and the auxiliary arms 204 to move downward until the arc plate 205 is close to the outer wall of the pipe, and then the fixing screws are re-tightened to allow the auxiliary structure 2 and the supporting structure 6 to form two stable supporting forces on the left and right. Then the user can start the body 1 to control the hole opener 301 to rotate at high speed, and then hold the handle 5 to move the body 1 downward to cut the position where the hole needs to be opened. The body 1 drives the hole opener 301 to rotate at high speed to cut the pipe, and the downward cutting is performed during cutting. The force will be transmitted to the repulsive block and then act on the hole opener 301 to ensure the stability of the hole opener 301 during operation. The cut waste pieces will squeeze the limit block 308, and the limit block 308 will rotate upward to allow the waste pieces to enter the inside of the hole opener 301. After entering, the waste pieces will be adsorbed by the magnetic block 313. In addition to adsorbing the waste pieces, the magnetic block 313 can also reduce the falling of burrs and debris and prevent them from entering the pipeline. After cutting, the user can continue to move the hole opener 301 downward for a distance and use the grinding circle 302 provided on the outside of the hole opener 301 to grind the cutting port. Finally, when cleaning the waste pieces, the user closes the body 1 and manually pushes the hole opener 301 downward. The hole opener 301 with The movable tooth plate 307 moves downward along the slide bar 303 and compresses the spring 306. As the tooth plate 307 moves to mesh with the gear 310, the tooth plate 307 will drive the gear 310 to rotate, and the gear 310 will drive the movable belt 309 to move. The surface of the movable belt 309 is provided with a rubber pad to increase the friction with the surface of the waste sheet. At this time, the moving movable belt 309 can drive the waste sheet to move to one side, so that the waste sheet is discharged outward from the discharge chute 305. As long as the tooth plate 307 touches the gear 310, the waste sheet will move. The initial movement of the waste sheet will make room for the tooth plate 307 so that the tooth plate 307 that continues to move downward will not contact the waste sheet. After the waste sheet is discharged, the user can quickly disassemble the device and continue to use it at other punching locations.
