The inner wall of the outer shell 23 is attached to the outer wall of the outer shell 23. The left and right ends of the top of the C-shaped ring 31 are fixedly connected to the fixing plate 32. The fixing plate 32 is slidably connected to the hexagonal bolt 33. The left end of the hexagonal bolt 33 is threadedly connected to the limiting plate 34. The grip structure 4 includes a fixing ring 41. The outer wall of the outer shell 21 is fixedly connected to the fixing ring 41. The left and right ends of the fixing ring 41 are fixedly connected to the handle 42. The top outer wall of the handle 42 is fixedly connected to the anti-slip sleeve 43. The front end of the transmission rod 28 is fixedly connected to the grinding roller 5 by the fixing bolt. The extension distance of the grinding roller 5 can be freely adjusted by the telescopic structure 2, which is convenient for removing rust from welded pipes of different lengths, improving applicability. When the outer shell is moved, the internal transmission rod can be moved synchronously. The position of the outer shell 23 can be locked by the fixing structure 3, thereby preventing the outer shell 23 from sliding during operation.

[0018] Furthermore, the inner walls of the left and right ends of the outer shell 21 are provided with sliding grooves 22. The left and right sides of the outer shell 23 are fixedly connected with sliding rods 24. The sliding rods 24 slide back and forth in the sliding grooves 22, pulling the outer shell 23 forward. The outer shell 23 drives the transmission rod 28 forward through the bearing 210. The outer shell 23 moves forward along the sliding grooves 22 through the sliding rods 24.

[0019] Furthermore, the left and right ends of the front end of the transmission rod 25 are provided with sliding grooves 26, and the left and right sides of the rear end of the transmission rod 28 are fixedly connected to sliding rods 29. The sliding rods 29 slide back and forth in the sliding grooves 26, and the transmission rod 28 moves forward along the sliding grooves 26 through the sliding rods 29.

[0020] Furthermore, a handle 35 is fixedly connected to the left side of the limiting plate 34. The handle 35 is a hexagonal handle with an anti-slip coating on its surface. The anti-slip coating prevents slippage when rotating the handle 35, and the hexagonal handle is easier to hold.

[0021] Furthermore, a circular hole is provided in the middle of the grip 35, and the diameter of the circular hole is larger than that of the hexagonal bolt 33. The circular hole in the middle of the grip 35 prevents motion interference.

[0022] Furthermore, the anti-slip sleeve 43 is made of rubber, and the surface of the anti-slip sleeve 43 is provided with uneven texture. The anti-slip sleeve 43 can increase the friction between the handle 42 and the palm, and the uneven texture can increase the contact area between the anti-slip sleeve 43 and the palm, making it easier to grip and improving the stability when gripping.

[0023] Furthermore, the fixing plate 32 at the right end has a hexagonal groove, and the hexagonal groove engages with the hexagonal nut at the right end of the hexagonal bolt 33. The hexagonal groove can limit the hexagonal bolt 33 and prevent it from rotating.

[0024] Working principle: When adjusting the extension distance of the grinding roller 5, pull the outer shell 23 forward. The outer shell 23, through the bearing 210, simultaneously drives the transmission rod 28 forward. The outer shell 23 moves forward along the slide groove 22 via the slide rod 24, and the transmission rod 28 moves forward along the slide groove 26 via the slide rod 29. The extension distance of the grinding roller 5 can be freely adjusted through the telescopic structure 2, facilitating rust removal for welded pipes of different lengths and improving applicability. Moving the outer shell also drives the internal transmission rod to move synchronously, making operation convenient and quick. Rotating the handle 35 causes the limiting plate 34 to rotate, moving the limiting plate 34 to the left, so that the limiting plate 34 no longer abuts against the outer wall of the fixed plate 32, thereby allowing C to move. The ring 31 no longer clamps the outer shell 23, allowing the outer shell 23 to slide and adjust its length. After moving to a suitable distance, the handle 35 is reversed, causing the handle 35 to rotate the limiting plate 34, which moves the limiting plate 34 to the right and abuts against the outer wall of the fixing plate 32. The fixing structure 3 locks the position of the outer shell 23, preventing it from sliding during operation. The operation is convenient and quick, and easy to use. The user holds the handle 42 with one hand and the motor 1 with the other to hold the device. The anti-slip sleeve 43 increases the friction between the handle 42 and the palm, and the uneven pattern increases the contact area between the anti-slip sleeve 43 and the palm, making it easier to hold and improving stability during gripping.
