[0021] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] Reference Figures 1-6 As shown, this utility model provides a technical solution: a grooving cutter that is easy to install, including a handle 1, a mounting groove 2 on one side of the handle 1, a connecting block 3 slidably connected inside the mounting groove 2, a sealing block 4 fixed to the other end of the connecting block 3, a mounting rod 5 fixed to the other end of the sealing block 4, a cutter head 6 fixed to the other end of the mounting rod 5, a first sliding hole 7 penetrating into the mounting groove 2 on the other end of the handle 1, a control rod 8 slidably connected inside the first sliding hole 7, three locking blocks 9 fixed to one end of the control rod 8, the locking blocks 9 being circumferentially distributed around the axis of the control rod 8, and the end of the handle 1 away from the sealing block 4 having a... The connecting block 3 is provided with three first guide grooves 10 that are slidably connected to the card block 9. The connecting block 3 is provided with three second guide grooves 11 of the same specifications as the first guide grooves 10 at the end away from the sealing block 4. The connecting block 3 is provided with a second sliding hole 14 that communicates with the second guide grooves 11 at the end away from the sealing block 4. The inner diameter of the second sliding hole 14 is the same as that of the first sliding hole 7. A rotating chamber 12 is provided at one end of the second sliding hole 14. The height of the rotating chamber 12 is greater than the height of the card block 9. Three card slots 13 that cooperate with the card block 9 are provided at the top of the rotating chamber 12. A control block 15 is fixed at the end of the control rod 8 away from the card block 9.

[0023] The other end of the handle 1 is equipped with a limiting mechanism for limiting the control lever 8. The limiting mechanism includes two mounting blocks 18 fixed to one end of the handle 1. Three sliding rods 19 are slidably connected to both sides of the mounting blocks 18. One end of the sliding rod 19 is fixed with a limiting block 20, and the other end of the sliding rod 19 is fixed with a limiting bar 22. An arc-shaped groove 21 is opened on the side of the limiting block 20 near the control lever 8. By installing the connecting block 3 into the inside of the mounting groove 2, and then controlling the control block 15, the control lever 8 drives the locking block 9 to move inside the first sliding hole 7 and the first guide groove 10, and then enters the second sliding hole 14 and the second guide groove 11. Through the second sliding hole 14 and the second guide groove 11, it enters the inside of the rotating chamber 12, and rotates the locking block 9 through the inside of the rotating chamber 12. After rotating 60 degrees, Aligning the locking block 9 with the slot 13, pulling the control block 15 causes the locking block 9 to engage inside the slot 13, thus fixing the position of the connecting block 3 and completing the installation and fixation of the cutter head 6. After the cutter head 6 is installed, the limiting bar 22 causes the sliding rod 19 to move the limiting block 20, moving the limiting block 20 into the gap between the control block 15 and the tool holder 1, thereby limiting the position of the locking block 9 and making it difficult for the locking block 9 to disengage from inside the slot 13, thus ensuring the stability of the connection between the connecting block 3 and the tool holder 1. Through the cooperation of the locking block 9 and the slot 13, as well as the cooperation of the limiting mechanism, the entire installation process does not require any external tools, making the installation faster and more convenient. Furthermore, connecting the cutter head 6 with part of the tool holder increases the volume of the cutter head 6 to a certain extent, making it easier to handle.

[0024] Reference Figure 1 As shown in this embodiment: a first guide groove 16 is provided on one side of the sealing block 4, and a second guide groove 17 is provided on the same side of the knife handle 1 as the sealing block 4 to cooperate with the first guide groove 16. By referencing the first guide groove 16 and the second guide groove 17, the second guide groove 11 and the first guide groove 10 can be aligned when the connecting block 3 is inserted into the mounting groove 2, thereby ensuring that the locking block 9 can smoothly enter the interior of the rotating chamber 12.

[0025] Reference Figure 6 As shown in this embodiment: two first springs 23 are fixed on the side of the limiting block 20 away from the control rod 8. The other end of the first spring 23 is fixed to the mounting block 18. By setting the first spring 23, the position of the limiting block 20 can be continuously limited when the limiting block 20 limits the position of the control rod 8, so as to prevent the limiting block 20 from moving due to the vibration generated during the operation of the machine tool.

[0026] Reference Figure 3As shown in this embodiment: a circular top plate 24 is slidably connected inside the rotating chamber 12. A second spring 25 is fixed to the side of the circular top plate 24 near the sealing block 4. The other end of the second spring 25 is fixed to the inside of the rotating chamber 12. Through the cooperation of the circular top plate 24 and the second spring 25, when the locking block 9 enters the interior of the rotating chamber 12 through the second guide groove 11, it squeezes the circular top plate 24, causing the second spring 25 to store force. When the locking block 9 rotates to align with the locking groove 13, the rebound force generated by the second spring 25 drives the circular top plate 24, causing the circular top plate 24 to push the locking block 9 into the interior of the locking groove 13, thereby making the installation more convenient.

[0027] Reference Figure 5 As shown in this embodiment: the control lever 8 is provided with three third pointing grooves 26 at one end near the control block 15. The opening of the third pointing grooves 26 makes it easier for the user to identify the position of the card block 9, so that the card block 9 can be better inserted into the card slot 13.

[0028] Working principle: By installing the connecting block 3 into the mounting slot 2, and then controlling the control block 15, the control rod 8 moves the locking block 9 inside the first sliding hole 7 and the first guide groove 10, and then into the second sliding hole 14 and the second guide groove 11. Through the second sliding hole 14 and the second guide groove 11, it enters the rotating chamber 12, where it rotates 60 degrees, aligning the locking block 9 with the slot 13. By pulling the control block 15, the locking block 9 is engaged in the slot 13, thus fixing the position of the connecting block 3. The installation and fixing of the paired cutter heads 6: After the cutter heads 6 are installed, the limiting bar 22 causes the sliding bar 19 to move the limiting block 20, moving the limiting block 20 into the gap between the control block 15 and the tool holder 1. This limits the position of the locking block 9, making it difficult for the locking block 9 to disengage from the inside of the slot 13, thus ensuring the stability of the connection between the connecting block 3 and the tool holder 1. Through the cooperation of the locking block 9 and the slot 13, as well as the cooperation of the limiting mechanism, the entire installation process does not require any external tools, making the installation faster and more convenient. Furthermore, it secures the cutter head 6 and part of the tool holder... The connection increases the volume of the cutter head 6 to some extent for easier handling. The reference between the first guide groove 16 and the second guide groove 17 ensures that the second guide groove 11 and the first guide groove 10 are aligned when the connecting block 3 is inserted into the mounting groove 2, thus ensuring that the locking block 9 can smoothly enter the rotating chamber 12. The first spring 23 continuously limits the position of the limiting block 20 when it limits the position of the control rod 8, preventing the limiting block 20 from moving due to vibrations generated during machine operation. With the cooperation of the circular top plate 24 and the second spring 25, when the locking block 9 enters the interior of the rotating chamber 12 through the second guide groove 11, it presses the circular top plate 24, causing the second spring 25 to store force. When the locking block 9 rotates to align with the locking groove 13, the rebound force generated by the second spring 25 drives the circular top plate 24, causing the circular top plate 24 to push the locking block 9 into the interior of the locking groove 13, thus making the installation more convenient. The opening of the third guide groove 26 makes it easier for the user to identify the position of the locking block 9, thereby making the locking block 9 better fit into the interior of the locking groove 13.
