Technical Field
[0001] This utility model relates to the field of cutting tool technology, and in particular to a cutting tool with an adjustable angle. Background Technology
[0002] Cutting tools are tools used for cutting processes in mechanical manufacturing. The vast majority of tools are machine-made, but some are hand-operated. Since tools used in mechanical manufacturing are primarily for cutting metal materials, the term "tool" is generally understood to refer to metal cutting tools. Tools used for cutting wood are called woodworking tools. The materials used to manufacture tools must possess high high-temperature hardness and wear resistance, necessary bending strength, impact toughness, and chemical inertness, good machinability (cutting, forging, and heat treatment, etc.), and be resistant to deformation. Generally, higher material hardness corresponds to higher wear resistance; higher bending strength also corresponds to higher impact toughness. However, existing cutting tools are not convenient to adjust their angles in actual use, which limits their application range. When machining workpieces with different angles, different machining machines with different angles are required to complete the process. Therefore, it is necessary to provide a cutting tool with an adjustable angle to solve the above problems. Summary of the Invention
[0003] The main objective of this invention is to provide a cutting tool with an easily adjustable angle, which can effectively solve the problems in the background art.

An adjustment disc 11 is rotatably connected in the middle of the mounting sleeve 4. The adjustment disc 11 is located between the two mounting sleeves 4. One side of the outer wall of the adjustment disc 11 is connected to the mounting base 2 by bolts. An arc-shaped adjustment groove 5 is opened in the middle of the side wall of the mounting sleeve 4. The mounting base 2 is rotatably connected inside the arc-shaped adjustment groove 5. A rotating rod 7 is connected to the bottom center of the mounting sleeve 4 via a bearing, and a rotating handle 6 is installed at the bottom end of the rotating rod 7. The top end of the rotating rod 7 is connected to the bottom inner wall of the adjusting plate 11, and a limit ring 12 is fixedly connected to the top inner wall of the adjusting plate 11. The top end of the rotating rod 7 is rotatably connected to the limit ring 12. A drive gear 8 is engaged on the outer wall of the rotating rod 7, and an auxiliary gear 9 is provided on one side of the drive gear 8. The auxiliary gear 9 meshes with the drive gear 8, and a support rod 14 is engaged in the middle of the auxiliary gear 9. The bottom end of the support rod 14 is mounted on the bottom inner wall of the mounting sleeve 4 via a bearing, and a limit plate 13 is installed at the top and bottom of the auxiliary gear 9. There are four limiting plates 13, which are symmetrically distributed on the top and bottom of the auxiliary gear 9 and the top and bottom of the driving gear 8. A driven rack 10 is provided on one side of the auxiliary gear 9, and the driven rack 10 is fixedly connected to the inner wall of the adjusting plate 11. The auxiliary gear 9 and the driven rack 10 mesh with each other. The rotating handle 6 drives the rotating rod 7 and the driving gear 8 to rotate, so that the auxiliary gear 9 drives the driven rack 10 and the adjusting plate 11 to rotate. During the rotation, the adjusting plate 11 drives the mounting base 2 to adjust the angle of the cutting tool 1. The driving gear 8, the auxiliary gear 9 and the driven rack 10 improve the stability of the adjustment angle. Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, an L-shaped mounting bracket 15 is provided on one side of the bottom of the mounting sleeve 4. A threaded support seat 16 and a threaded positioning rod 17 are provided in the middle of the L-shaped mounting bracket 15. A rotating handle 18 and a rubber positioning block 19 are respectively provided at both ends of the threaded positioning rod 17. The L-shaped mounting bracket 15 is bolted to one side of the bottom of the mounting sleeve 4. The threaded support seat 16 is bolted to the middle of the L-shaped mounting bracket 15. The threaded positioning rod 17 is threadedly connected to the middle of the threaded support seat 16. The threaded positioning rod 17 passes through the L-shaped mounting bracket 15 and the threaded support seat 16. The L-shaped mounting bracket 15 is arranged adjacent to the rotating handle 6. One end of the rotating handle 18 is fixedly connected to the rotating handle 6, and the rotating handle 18 is located at the end of the threaded positioning rod 17 away from the rotating handle 6. A rubber positioning block 19 is installed at the end of the threaded positioning rod 17 close to the rotating handle 6, and the rubber positioning block 19 is in contact with the outer wall of the rotating handle 6. By rotating the rotating handle 18, the rotating handle 18 drives the threaded positioning rod 17 to push out the rubber positioning block 19, so that the threaded positioning rod 17 compresses the rubber positioning block 19 between the rotating handle 6 and the threaded positioning rod 17, thereby achieving the positioning of the rotating handle 6 and preventing the rotating handle 6 from rotating when the cutting tool 1 is in use, which would affect the stability of the adjustment.
[0019] It should be noted that this utility model is a cutting tool with an easily adjustable angle. In use, the device is installed in the desired position via the adapter 20. Rotating the rotating handle 6 causes the rotating rod 7 and the driving gear 8 to rotate. The side of the driving gear 8 meshes with the auxiliary gear 9, and the auxiliary gear 9 meshes with the driven rack 10. This causes the driven rack 10 to drive the adjusting disc 11 to rotate uniformly along the inside of the mounting sleeve 4. One outer wall of the adjusting disc 11 is connected to the mounting base 2. The mounting base 2 drives the cutting tool 1 to rotate along the arc-shaped adjusting groove 5 on one side of the two mounting sleeves 4, thus adjusting the angle of the cutting tool 1. The driving gear 8 and... Limiting plates 13 are provided at the top and bottom of the auxiliary gear 9 to limit the connection between the driving gear 8 and the auxiliary gear 9, thereby improving the stability of both during use. After adjustment, rotate the rotating handle 18 on one side of the L-shaped mounting bracket 15, so that the rotating handle 18 drives the threaded positioning rod 17 to move closer to the rotating handle 6. The threaded positioning rod 17 pushes out the rubber positioning block 19, so that the rubber positioning block 19 fits tightly with the rotating handle 6. The threaded positioning rod 17 presses the rubber positioning block 19 between the rotating handle 6 and the threaded positioning rod 17, thus completing the positioning of the rotating handle 6 and preventing the rotating handle 6 from rotating during use, which would affect the stability of use.
