[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a center water outlet clamping mechanism with an inverted 7-shaped structure, comprising: a cutter holder 1, a side fixing seat 3 on the side of the cutter holder 1 and a mounting seat 4 on the side of the side fixing seat 3, a cutter groove 5 inside the cutter holder 1 and a fastener 6 on the upper part of the cutter holder 1, the fastener 6 being threadedly connected to the cutter holder 1 and extending into the cutter groove 5, a water inlet connector 2 on the side of the cutter holder 1 and a flow channel 10 inside the cutter holder 1, the flow channel 10 being connected to the water inlet connector 2, and a water outlet pipe 13 on the upper part of the flow channel 10. The water outlet pipe 13 extends to the outside of the tool holder 1 and is equipped with a water outlet connector 14. The water outlet connector 14 is located above the side of the tool groove 5. An adjustment knob 8 is installed on the surface of the water outlet connector 14. The surface of the water outlet connector 14 is provided with external threads, and the adjustment knob 8 is threadedly connected to the water outlet connector 14. A water outlet 9 is provided on the side of the adjustment knob 8. A side fixing seat 3 is provided on the side of the tool holder 1, and a mounting seat 4 is provided on the side of the side fixing seat 3. This arrangement makes the tool holder 1 form an inverted 7-shaped structure, which facilitates the installation and connection of the tool holder 1 with the cutting machine tool and ensures the stability and firmness of the tool holder 1 installation. The tool holder 1 has a tool groove 5 inside and a fastener 6 on its upper part. The fastener 6 is threaded to the tool holder 1 and extends into the tool groove 5. A water inlet connector 2 is provided on the side of the tool holder 1, and a flow channel 10 is provided inside the tool holder 1, which is connected to the water inlet connector 2. A water outlet pipe 13 is provided on the upper part of the flow channel 10 and extends to the outside of the tool holder 1, where a water outlet connector 14 is installed. The water outlet connector 14 is located on the upper side of the tool groove 5, and an adjustment knob 8 is installed on the surface of the water outlet connector 14. The surface of the water outlet connector 14 is provided with external threads and is adjustable. The adjustment knob 8 is threadedly connected to the water outlet connector 14. A water outlet 9 is provided on the side of the adjustment knob 8. When cooling the cutting tool clamped in the tool slot 5, the adjustment knob 8 is rotated so that the water outlet 9 is located above the cutting tool. The cutting fluid enters the water outlet pipe 13 through the water inlet connector 2 and the flow channel 10. It then enters the water outlet connector 14 through the water outlet pipe 13 and is sprayed out from the water outlet 9 of the adjustment knob 8. It can directly act on the tip of the cutting tool, thereby increasing the tool's service life. At the same time, rotating the adjustment knob 8 can also adjust its length within a certain range, allowing the use of cutting tools of different lengths.

[0020] Further improvements, such as Figure 1 As shown: The tool holder 1, the layer of electronic components, and the mounting base 4 form an inverted 7-shaped structure. The inverted 7-shaped structure design makes it easier to install and connect the tool holder 1 with the cutting machine tool, enhances the stability and firmness of the tool holder 1 installation, reduces vibration and displacement during the machining process, and improves machining accuracy.

[0021] Further improvements, such as Figure 1 As shown: The top of the fastener 6 is provided with a welding fastening knob 7. The welding fastening knob 7 ensures that the fastener 6 will not loosen or fall off during operation, which improves the reliability and safety of the clamping mechanism, and at the same time facilitates the operator to perform fastening and loosening operations quickly.

[0022] Further improvements, such as Figure 3 As shown: A ball valve 12 is provided inside the flow channel 10, and a valve stem 11 is provided on the top of the ball valve 12. The valve stem 11 extends to the outside of the tool holder 1 and is equipped with a handle 16. The valve stem 11 and the ball valve 12 are controlled by the handle 16, which can conveniently control the flow and cut-off of the cutting fluid, realize flexible control of the cutting fluid supply, and help save cutting fluid and reduce unnecessary waste.

[0023] Further improvements, such as Figure 4 As shown: The inner side of the water outlet connector 14 is provided with a limiting block 15. The design of the limiting block 15 can prevent the adjustment knob 8 from being over-rotated or falling off during the rotation process, ensuring the stability and safety of the water outlet connector 14. At the same time, it limits the adjustment range of the adjustment knob 8 to prevent the cooling effect from being affected due to over-adjustment.

[0024] Further improvements, such as Figure 4 As shown: A sealing ring is provided at the connection between the adjustment knob 8 and the water outlet connector 14. The sealing ring can effectively prevent the cutting fluid from leaking at the connection between the adjustment knob 8 and the water outlet connector 14, ensuring the sealing and cleanliness of the clamping mechanism and reducing the pollution of the cutting fluid to the machine tool and the environment.

[0025] Working Principle: The tool holder 1 is installed and connected to the cutting machine tool via the side fixing seat 3 and the mounting seat 4, forming a stable inverted 7-shaped structure. This inverted 7-shaped structure design enhances the stability and robustness of the connection between the tool holder 1 and the machine tool, reduces vibration and displacement during machining, provides a stable foundation for subsequent machining operations, improves machining accuracy and efficiency, and extends the service life of both the tool and the machine tool. The cutting tool is clamped in the tool slot 5 and secured by fasteners 6 and fastening knobs 7. The design of fasteners 6 and fastening knobs 7 ensures the stability of the cutting tool during machining. The robust design prevents the cutting tool from loosening or falling off due to excessive cutting force, improving machining safety and reliability, and reducing machining accidents caused by loose cutting tools. Depending on the cutting tool length and machining requirements, rotating the adjusting knob 8 positions the outlet 9 above the cutting tool, and the ball valve 12 is controlled by the handle 16 to regulate the flow of cutting fluid. The design of the adjusting knob 8 allows for flexible adjustment of the outlet 9 position according to the cutting tool length and machining requirements, ensuring that the cutting fluid acts directly on the cutting tool tip, effectively reducing cutting temperature. Simultaneously, the ball valve 12 design enables flexible control of the cutting fluid supply, improving tool life and machining efficiency, and reducing tool wear and machining quality degradation caused by excessive cutting temperature. Furthermore, flexible control of the cutting fluid supply helps conserve cutting fluid and reduce unnecessary waste.
