[0015] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0016] Example 1: This embodiment provides a pipe cutting device that is easy to position, including: The first handle 1 has a blade portion 2 formed at one end; The second handle 3 is hinged to the first handle 1, and one end forms a knife holder 4 that is adapted to the blade part 2; The distance measuring mechanism 5 is installed on one side of the tool holder 4 and is used to measure the moving distance and provide feedback display when the tool holder 4 moves along the pipe 11.

[0017] As can be seen from this embodiment, the blade part 2 and the blade holder part 4 are driven to cooperate by the first handle 1 and the hinged second handle 3, which can conveniently cut the pipe 11. A distance measuring mechanism 5 is set on one side of the blade holder part 4 so that when the first handle 1 and the second handle 3 are moved along the pipe 11, the moving distance can be measured and displayed, which makes it easier to determine the cutting position. Cutting can be carried out when the cutting position is reached, which effectively improves the cutting efficiency.

[0018] Example 2: This embodiment provides a pipe cutting device that is easy to position. In addition to the technical solutions of the above embodiments, it also has the following technical features: the ranging mechanism 5 includes: The roller assembly 6 is connected to the side of the tool holder 4 and is used to measure the moving distance of the tool holder 4 and provide feedback. The display component 7 is mounted on the side of the tool holder 4, with one end hinged to the roller assembly 6 and the other end snapped to the roller assembly 6. It is used to receive feedback from the roller assembly 6 and calculate and display the measurement results. The roller assembly 6 and the display assembly 7 clamp the pipe 11.

[0019] As can be seen from this embodiment, by using the roller assembly 6 and the display assembly 7 to clamp the pipe 11, not only is slippage between the roller assembly 6 and the pipe 11 effectively reduced and the measurement accuracy improved, but the display assembly 7 also facilitates the display of the measurement data, making it easy for the user to understand, thus effectively improving the cutting accuracy and efficiency. Meanwhile, the hinge and snap-fit ​​connections at both ends effectively improve convenience, and the clamping connection between the roller assembly 6 and the physical assembly on the pipe 11 also improves stability when moving along the pipe 11 under force, and ensures cutting accuracy after moving into position.

[0020] Example 3: This embodiment provides a pipe cutting device that is easy to position. In addition to the technical solutions of the above embodiments, it also has the following technical features: the roller assembly 6 includes: The base 60 is connected to the side of the tool holder 4; Roller 61 is mounted on base 60, and has shafts 62 at both ends connected to the bearings of base 60; A circular grid disc 63 is coaxially mounted on a shaft 62 on one side of the roller 61; Sensor 64 is installed in the base 60 and is set correspondingly to the circular grid disk 63, and is used to detect the rotation of the circular grid disk 63 and generate a corresponding electrical signal. Among them, the circular grid disk 63 and the sensor 64 are usually referred to as encoders. Their specific structure and working principle are existing mature technologies, which are known to those skilled in the art from traditional encoders, and will not be described in detail here. Meanwhile, the base 60 and the tool holder 4 can be welded together, while the roller 61 and the shaft 62 adopt an integrated structure, and the circular grid plate 63 and the shaft 62 are fastened together with bolts.

[0021] As can be seen from this embodiment, the base 60 facilitates the mounting of the roller 61 on the side of the cutter holder 4, and the roller 61 is provided with shafts 62 at both ends. The bearing connection reduces the resistance to the rotation of the roller 61, thereby preventing the roller 61 from slipping when it comes into contact with the pipe 11. The use of the circular grid disk 63 and the sensor 64, i.e., the encoder, can effectively obtain the number of rotations of the roller 61 and the angle data of the last non-full rotation. The moving distance can be calculated by the circumference of the roller 61, thereby locating the cutting position and ensuring accuracy and efficiency.

[0022] Example 4: This embodiment provides a pipe cutting device that is easy to position. In addition to the technical solutions of the above embodiments, it also has the following technical features: the display component 7 includes: The housing 70 is hinged at one end to the base 60 and snap-fitted at the other end to the base 60; A microprocessor 71 is installed inside the housing 70 and is used to receive electrical signals from the sensor 64 and calculate the measurement results. The display screen 72 is mounted on the housing 70 and is used to display the measurement results calculated by the microprocessor 71; The specific structures of the microprocessor 71 and the display screen 72, as well as the method by which the microprocessor 71 receives the electrical signals from the sensor 64, are all existing mature technologies and will not be described in detail here.

[0023] As can be seen in this embodiment, the microprocessor 71 receives the electrical signal fed back by the sensor 64, which includes the number of rotations of the roller 61 and the angle data of the last non-full rotation. It then calculates the moving distance and displays the data on the display screen 72, thereby improving the accuracy and convenience of data reading.

[0024] Example 5: This embodiment provides a pipe cutting device that is easy to position. In addition to the technical solutions of the above embodiments, it also has the following technical features: The display component 7 further includes: A reset button 73 is mounted on the housing 70, and when pressed, it can send an electrical signal to reset the data on the display screen 72. Among them, the microprocessor 71 is capable of receiving an electrical signal to reset the data of the display screen 72; Meanwhile, the specific structure and working principle of the reset button 73 are existing mature technologies, and will not be elaborated here.

[0025] As can be seen from this embodiment, the reset button 73 facilitates the reset of the data displayed on the display screen 72, thereby improving the efficiency and accuracy of continuous multiple cuts and enhancing convenience.

[0026] Example 6: This embodiment provides a pipe cutting device that is easy to position. In addition to the technical solutions of the above embodiments, it also has the following technical features: The roller 61 has annular grooves 65 at both ends of the axial direction, and an annular protrusion 66 is formed between the two annular grooves 65. Among them, the annular groove 65 is fitted with an elastic washer 67; Meanwhile, the elastic washer 67 is made of rubber.

[0027] As can be seen from this embodiment, by opening annular grooves 65 at both ends of the roller 61 and installing elastic washers 67 made of rubber in the annular grooves 65, the friction between the roller 61 and the pipe 11 is effectively increased, further preventing slippage and improving measurement accuracy. Specifically, roller 61 moves and rolls along pipe 11, with its axis perpendicular to the axis of pipe 11. This means the contact area between roller 61 and pipe 11 is small, and the contact area is at the annular protrusion 66. Therefore, when calculating the movement distance of roller 61, the circumference of the annular protrusion 66 is used as the coefficient in the calculation formula. Roller 61, elastic washer 67, and circular grid disk are all coaxially arranged and fixed to each other, with no relative rotational deviation. In other words, the number of rotations of the circular grid disk is the same as the number of rotations of roller 61, and the number of rotations of elastic washer 67 along pipe 11 is the same as the number of rotations of roller 61 along pipe 11. Therefore, the accuracy of movement distance detection can be effectively improved, ensuring positioning accuracy.

[0028] Example 7: This embodiment provides a pipe cutting device that is easy to position. In addition to the technical solutions of the above embodiments, it also has the following technical features: A first arc-shaped surface 74 is provided on the side of the housing 70 near the base 60; The elastic washer 67 extends away from the annular protrusion 66 to the side away from the axis, and forms a second arc-shaped surface 68 on the surface of the elastic washer 67. Among them, friction-enhancing textures can also be formed on the second arc-shaped surface 68.

[0029] As can be seen from this embodiment, by setting the first arc-shaped surface 74 and the second arc-shaped surface 68 on the housing 70 and the elastic washer 67 respectively, and the friction-enhancing texture on the second arc-shaped surface 68, the fit between the roller 61 and the pipe 11 is improved, which can further improve the sliding friction resistance between the roller 61 and the pipe 11, thereby further reducing the possibility of slippage and improving the measurement accuracy.

[0030] Example 8: This embodiment provides a pipe cutting device that is easy to position. In addition to the technical solutions of the above embodiments, it also has the following technical features: A hook 8 is provided on one side of the base 60, and a slot 9 adapted to the hook 8 is provided on one side of the housing 70, and a hole 10 penetrating the inner wall of the slot 9 is provided on the inner wall of the slot 9. The hook 8 and the base 60 can be welded together.

[0031] As can be seen from this embodiment, by having the hook 8 extend into the slot 9 and engage with the hole 10, the ease of disassembly and assembly between the ranging mechanism 5 and the pipe 11 can be effectively improved, and the cutting efficiency can be increased. Furthermore, by placing the hook 8 on one side of the base 60 and the slot 9 and hole 10 on one side of the housing 70, the impact on the separation of the hook 8 and hole 10 when the housing 70 is flipped through the hinge connection is reduced.

[0032] The method of using this application is as follows: the pipe 11 is passed through the cutter head 4 along the roller 61 on the base 60, and then the housing 70 is flipped so that the hook 8 and the locking hole 10 cooperate to clamp the pipe 11. The blade 2 is then aligned with the cutting surface of the pipe 11. The reset button 73 is then pressed. Then, the pipe 11 is held in one hand and the first handle 1 and the second handle 3 are held in the other hand. The pipe 11 is pushed towards the cutter head 4 until the display screen 72 shows the pipe 11 of the required length. The pushing of the pipe 11 is then stopped. Finally, the other hand applies force to cut the pipe 11 through the blade 2 and the cutter head 4. If further cutting is needed, the pipe 11 can be pushed to move. The operation is convenient and can quickly locate the cutting position, which greatly improves the cutting efficiency.

[0033] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
