The adjustment structure 6 is provided on the upper surface of the body 1. An auxiliary structure 7 is provided on the inner wall of the connecting frame 3.

[0031] In the embodiments of this utility model, please refer to Figure 2 and Figure 3The adjusting structure 6 includes a limiting block 604, which is fixedly connected to the body 1. A connecting shaft 610 is rotatably connected to the inner wall of the limiting block 604. A knob 611 is slidably connected to one end of the connecting shaft 610. Several insert rods 614 are fixedly connected to the side of the knob 611 near the limiting block 604, and these insert rods 614 are adapted to the limiting block 604. A scroll 615 is fixedly connected to the arc surface of the connecting shaft 610, and a connecting belt 602 is fixedly connected to the arc surface of the scroll 615. A fixing block 601 is fixedly connected to the end away from the scroll 615. The fixing block 601 is fixedly connected to the connecting frame 3. Fixing plates 606 are fixedly connected to both sides of the body 1. Connecting plates 608 are fixedly connected to both sides of the connecting frame 3. A spring 607 is provided between the fixing plate 606 and the connecting plate 608. The two ends of the spring 607 are fixedly connected to the fixing plate 606 and the connecting plate 608 respectively. A connector 605 is fixedly connected to the end of the connecting frame 3 closest to the body 1. The connector 605 is slidably connected to the body 1. When different types of steel pipes need to be cut, the knob 611 is pulled to move it. The knob 611 moves the insertion rod 614, which then separates from the limit block 604. The knob 611 slides on the arc surface of the connecting shaft 610. Then, the connecting frame 3 is pulled to move it, which moves the connecting piece 605. The connecting piece 605 slides on the inner wall of the machine body 1. The fixing block 601 moves the connecting belt 602, which in turn moves the winding shaft 615. The winding shaft 615 then rotates the connecting shaft 610, which in turn rotates the knob 611. Finally, the connecting frame 3 moves the connecting plate 608, which then moves the connecting plate 608. The spring 607 is stretched, and then the steel pipe is placed into the connecting frame 3 and the machine body 1. Then the connecting frame 3 is released and the spring 607 is contracted, which causes the connecting frame 3 and the machine body 1 to clamp the steel pipe. Then the knob 611 is turned to drive the connecting shaft 610 to rotate. The connecting shaft 610 drives the winding shaft 615 to rotate. The winding shaft 615 drives the connecting belt 602 to retract. Then the insertion rod 614 is aligned with the appropriate limiting block 604. Then the knob 611 is pushed to drive the insertion rod 614 to insert into the limiting block 604 for fixation. The fixing plate 606 is fixedly connected to the sliding rod 603 on the side near the connecting plate 608. The sliding rod 603 is slidably connected to the connecting plate 608. The spring 607 is sleeved on the arc surface of the sliding rod 603. The slide bar 603 can limit the spring 607, preventing deformation during use and improving its service life. Several positioning rods 613 are fixedly connected to the arc surface of the connecting shaft 610 near the knob 611, and these positioning rods 613 are slidably connected to the knob 611. The positioning rods 613 can limit the knob 611, preventing rotation during use. Coil springs 609 are fitted onto the arc surfaces at both ends of the connecting shaft 610, and the two ends of the coil springs 609 are fixedly connected to the limiting block 604 and the coil shaft 615, respectively.When the connecting belt 602 is stretched, the reel 615 drives the winding mechanism to rewind. Then, the rebound force of the coil spring 609 drives the connecting belt 602 to rewind as well. The knob 611 has several slots 612 evenly distributed on its arc-shaped surface. The slots 612 increase the friction between the hand and the knob 611, preventing slippage when pulling or rotating it.

[0032] In the embodiments of this utility model, please refer to Figure 1 and Figure 4 The auxiliary structure 7 includes two connecting blocks 71, both of which are fixedly connected to the connecting frame 3. The inner wall of the connecting frame 3 has a connecting groove 72. A rotating shaft 73 is rotatably connected to the inner wall of each connecting block 71. A roller 74 is fixedly connected to the arc surface of the rotating shaft 73 and is positioned inside the connecting groove 72. When clamping and cutting the pipe, the pipe is placed between the two rollers 74. The connecting frame 3 then moves the connecting blocks 71, which in turn moves the rotating shaft 73. The rotating shaft 73 then moves the rollers 74, which clamp the steel pipe. As the steel pipe rotates, the rollers 74 drive the rotating shaft 73 to rotate within the inner wall of the connecting blocks 71. The arc surface of the rollers 74 has several auxiliary grooves 75, evenly distributed on the rollers 74. The auxiliary grooves 75 increase the friction between the rollers 74 and the steel pipe, preventing slippage and wear of the rollers 74 during clamping and fixing.

[0033] The working principle of the portable electric stainless steel pipe cutting device provided by this utility model is as follows: When it is necessary to cut steel pipes of different models, pull the knob 611 to move it. The knob 611 drives the insertion rod 614 to move. Then the insertion rod 614 separates from the limiting block 604. The knob 611 slides on the arc surface of the connecting shaft 610. Then pull the connecting frame 3 to move it. The connecting frame 3 drives the connecting piece 605 to move. The connecting piece 605 slides on the inner wall of the machine body 1. The fixing block 601 drives the connecting belt 602 to move. The connecting belt 602 drives the winding shaft 615 to rotate. The winding shaft 615 drives the connecting shaft 610 to rotate. The connecting shaft 610 drives the knob 611 to rotate. Then the connecting frame 3 drives the connecting plate 608 to move. The connecting plate 608 drives the spring 607 to stretch. Then the steel pipe is placed into the connecting frame 3 and the machine body 1. Then the connecting frame 3 is released and the spring 607 retracts. The connecting frame 3 and the body 1 clamp the steel pipe. Then, the knob 611 is turned to drive the connecting shaft 610 to rotate. The connecting shaft 610 drives the winding shaft 615 to rotate. The winding shaft 615 drives the connecting belt 602 to retract. Then, the insertion rod 614 is aligned with the appropriate limiting block 604. Then, the knob 611 is pushed to drive the insertion rod 614 to insert into the limiting block 604 for fixation. The slide rod 603 can limit the spring 607 to prevent the spring 607 from deforming during use and improve the service life of the spring 607. The positioning rod 613 can limit the knob 611 to prevent the knob 611 from rotating during use. When the connecting belt 602 is stretched, the winding shaft 615 drives the winding shaft 615 to rewind. Then, the rebound force of the coil spring 609 drives the connecting belt 602 to rewind. The slot 612 can increase the friction between the hand and the knob 611 to prevent slippage when pulling and turning the knob 611.

[0034] When clamping and cutting the pipe, the pipe is placed between two rollers 74. Then, the connecting frame 3 drives the connecting block 71 to move, the connecting block 71 drives the rotating shaft 73 to move, the rotating shaft 73 drives the rollers 74 to move, and then the rollers 74 clamp the steel. When the steel pipe is rotated, the rollers 74 drive the rotating shaft 73 to rotate on the inner wall of the connecting block 71. The auxiliary groove 75 can increase the friction between the rollers 74 and the steel pipe, and prevent the rollers 74 from slipping when clamping and fixing the steel pipe, which would cause the rollers 74 to wear.
