[0025] In order to make the technical means, creative characteristics, purposes and effects realized by the utility model easy to understand, the utility model is further described below in combination with specific embodiments, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative labor all belong to the protection scope of the utility model. In the following embodiments, the experimental methods are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0026] Example 1

[0027] This application includes a cutting device that can be used for handheld cutting, the cutting device comprising, as follows: Figure 4 The grip portion 2 shown is curved, making it easy for the user to hold. Its curved contour is similar to the curvature of the palm, improving the user's grip experience and stability. One end of the grip portion 2 is connected to a positioning portion 28, on which a cutting disc 211 is movably connected. The positioning portion 28 and the cutting disc 211 are connected via a […]. Figure 5 The adjustment assembly shown changes the position of the cutting disc 211 on the positioning part 28, allowing the cutting disc 211 to move along the axial direction of the positioning part 28. The adjustment assembly includes a lead screw 29 rotatably connected to the positioning part 28, a sliding block 210 threaded onto the lead screw 29, and the cutting disc 211 rotatably connected to the sliding block 210. A first motor for providing power to the cutting disc 211 is connected to the sliding block 210, and the drive shaft of the first motor is collinear with the axis of the cutting disc 211. During radial rotation of the lead screw 29 relative to its axis, it drives the sliding block 210 to move along its axis, thereby changing the cutting depth of the cutting disc 211 on the target pipe. This allows the pipe to be completely cut without the operator needing to move the device.

[0028] Example 2

[0029] Based on Embodiment 1, this device can switch between handheld and fixed cutting modes. The other end of the grip 2 is connected to a fixing component, which is used to mount the device onto a fixed structure, such as... Figure 1 The device includes a centrally hollowed-out limiting ring 12. A fixing component is connected to the limiting ring 12 and moves along the radial direction of the limiting ring 12, allowing the cutting device to move circumferentially with the axis of the limiting ring 12 as a reference and insert the pipe to be cut into the limiting ring 12, so that its axis is collinear with the axis of the limiting ring 12. The cutting device can cut the outer wall of the pipe during the movement and achieve circumferential cutting of the outer wall of the pipe as it moves, ensuring the accuracy of the cutting position.

[0030] The fixing component is as follows Figure 3The device includes a fixing part 21 connected to the other end of the gripping part 2. A clamping part 23 is movably connected to the fixing part 21. The fixing part 21 and the clamping part 23 are respectively connected to both ends of the limiting ring 12. The cooperation between the fixing part 21 and the clamping part 23 allows the cutting device to move radially along the limiting ring 12. A threaded rod 24 and an optical axis 25 are respectively connected to both ends of the clamping part 23. Both the threaded rod 24 and the optical axis 25 are slidably connected to the fixing part 21. A nut 27 is threaded onto the threaded rod 24. The nut 27 is located on the end face of the fixing part 21 away from the clamping part 23 and is used to adjust the distance between the clamping part 23 and the fixing part 21.

[0031] Furthermore, to reduce the friction between the fixing component and the limiting ring 12, a movable wheel 22 is rotatably connected to the fixing part 21. The outer ring of the movable wheel 22 is slidably connected to the limiting ring 12. A self-locking motor for controlling the rotation of the movable wheel 22 is connected to the movable wheel 22. The self-locking motor is connected to the fixing part 21, and its connecting shaft is connected to the movable wheel 22 and collinear with the axis of the movable wheel 22. The self-locking motor can switch the state of rotation or locking of the movable wheel 22 and control the rotation direction of the movable wheel 22, so that the movable wheel 22 can rotate around its own axis to drive the cutting device to move along the contour of the limiting ring 12. One or more ball bearings 26 are provided on the clamping part 23. The ball bearings 26 are sleeved on the clamping part 23 and connected to the limiting ring 12. The rotation of the ball bearings 26 further reduces the friction between the device and the limiting ring 12.

[0032] Furthermore, to ensure the secure connection between the fixing component and the limiting ring 12, limiting grooves 14 are symmetrically provided at both ends of the limiting ring 12. The moving wheel 22 and the ball 26 are slidably connected to the corresponding limiting grooves 14. The limiting grooves 14 are used to restrict the movement of the connected moving wheel 22 or the ball 26, so that they can only move in the radial direction of the limiting groove 14, thereby avoiding the possibility of the fixing component rotating in the radial direction on the limiting ring 12.

[0033] Example 3

[0034] Based on Embodiment 2, the limiting ring 12 is connected with the following: Figure 2The connecting rod 13 shown has one or more connections to the bottom end of the limiting ring 12. One end of the connecting rod 13 is connected to the limiting ring 12, and the other end is connected to the base 1 for supporting the entire device. The diameter of the connecting rod 13 is less than or equal to the minimum distance between the clamping part 23 and the fixing part 21 to ensure that the cutting device can move around the connecting rod 13 on the limiting ring 12. Multiple telescopic rods 11 are connected to the end face of the base 1 that contacts the ground. The telescopic rods 11 are used to change the distance between the limiting ring 12 and the ground, ensuring that the axis of the limiting ring 12 is collinear with the axis of the target pipe, thus ensuring the cutting effect of the device. The telescopic rods 11 are symmetrically arranged at both ends of the base 1 to ensure the stability of the device on the ground.
