In order to understand the technical features and practical effects of the present invention in detail and implement them according to the contents of the manual, the preferred embodiments shown in the drawings are further described in detail as follows: The present invention provides a knife handle with enhanced cooling water outlet effect, and its first preferred embodiment is as shown in Figures 1 to 4, including a knife handle body 10 and a plurality of flow channel systems 20, wherein the knife handle body 10 includes a handle section 11, a flange portion 12 and a tool combining section 13 connected in sequence, and its main structure is roughly the same as that of the existing knife handle, and the two ends of the tool combining section 13 are respectively a front end 131 and a rear end 132, wherein the rear end 132 is connected to the flange portion 12. Please refer to Figures 2 and 4. The interior of the tool coupling section 13 is provided with a water inlet groove 133, a coupling groove 134, an annular groove 135 and an annular bevel 136. The coupling groove 134 is coaxially formed at the center of the tool coupling section 13, connected to the water inlet groove 133, and has a notch near the front end 131. The annular groove 135 is formed on the inner side wall of the coupling groove 134 near the notch, and the annular bevel 136 connects the annular groove 135 to one side of the notch.

Furthermore, as shown in FIG. 6 and FIG. 6A, there is an angle θ between the annular bevel 136 and an axis A1 of the handle body 10 (for ease of marking and understanding, the angle θ is marked with a parallel line P parallel to the axis A1 in FIG. 6A), and it gradually expands toward the notch, and the water inlet groove 133, the coupling groove 134, the annular groove 135 and the annular bevel 136 are all coaxial with the axis A1 of the handle body 10.

Please refer to Figures 2 to 5. The plurality of flow channel systems 20 are formed at intervals on the handle body 10. The flow channel system 20 includes an inlet flow channel 21, a main flow channel 22, and a branch flow channel 23. The inlet flow channel 21 is provided at the tool joint section 13 and connected to the water inlet groove 133. The main flow channel 22 extends from the inlet flow channel 21 and passes through the front end 131 of the tool joint section 13. The branch flow channel 23 extends obliquely from the main flow channel 22 and connects to the annular groove 135 of the tool joint section 13.

Please refer to FIG. 6 and FIG. 7. With the above technical features, the coolant can be sprayed from the water inlet groove 133 through the inlet channel 21 and the main channel 22 of each of the channel systems 20 to cool and lubricate the cutting part of the tool 80 installed in the tool joint section 13. When part of the coolant passes through the main channel 22 and the corresponding branch channel 23, it will flow to the annular groove 135 through the branch channel 23, and further flow out through the gradual expansion structure of the annular slope 136, maintaining the flow of the coolant to effectively cool the tool 80. Therefore, the present invention effectively improves the problem of insufficient cooling effect of the existing cooling water outlet tool handle, thereby enhancing the cooling effect of the tool installed on the tool handle through the configuration of the channel.

Furthermore, please refer to FIG. 6 , where the angle θ between the annular bevel 136 and the axis A1 is between 1 degree and 5 degrees, including end point values, and the cooling liquid is controlled to pass through the annular groove 135 and the annular bevel 136 at an optimal flow rate and flow rate by the angle range. In the first preferred embodiment of the present invention, the angle θ is 2 degrees. Furthermore, as shown in FIG. 6 , the annular groove 135 has a groove bottom surface 139, and the groove bottom surface 139 forms an inner R angle, so that the cooling liquid can flow into the annular groove 135 from the branch flow channel 23 of the plurality of flow channel systems 20, flow smoothly in the annular groove 135, surround the tool 80, and then flow out through the annular bevel 136 to form an annular water curtain, so as to better flush the metal powder generated by the cutting process on the surface of the tool 80, and achieve the effect of cooling and cleaning at the same time.

Please refer to Figures 3, 5 and 6. The plurality of flow channel systems 20 are radially arranged at equal angles with the axis A1 as the center on the tool joint section 13. For example, when the number of the flow channel systems 20 is three, any two adjacent flow channel systems 20 form an angle of 120 degrees, so as to evenly cool the tool joint section 13 and the tool 80.

As shown in FIG. 5 , the inlet channel 21 of each flow channel system 20 is drilled radially from the outside to the inside near the rear end 132 of the tool combination section 13 to communicate with the water inlet groove 133, and then sealed at the outer opening of the inlet channel 21 through a sealing member 210; as shown in FIG. 4 and FIG. 6 , the main channel 22 of each flow channel system 20 is formed by the front end 131 of the tool combination section 13 Drilled at an angle to the axis A1 to connect with the corresponding inlet channel 21; as shown in FIG6, the branch channel 23 of each channel system 20 is drilled obliquely from the notch of the coupling groove 134 to the inner side wall of the coupling groove 134 to connect with the corresponding main channel 22, and the branch channel 23 of the channel system 20 extends from the main channel 22 to the notch of the coupling groove 134. The above-mentioned structural configuration is formed by a simple drilling process, thereby improving the manufacturing cost efficiency of the knife handle with enhanced cooling water discharge effect of the present invention, so as to facilitate industrial utilization.

Further, please refer to FIG. 8 , the knife combination section 13A of the knife handle body 10A of the second preferred embodiment of the present invention is substantially the same as that of the first preferred embodiment, except that the sizes of the water inlet groove 133A and the combination groove 134A are smaller than those of the first preferred embodiment, so as to match knives of different sizes. At this time, since the combination groove 134A is narrower and shorter, the water inlet groove 133A is The setting position is also offset from the rear end 132A of the tool combination section 13A, and is roughly located in the middle section between the front end 131A and the rear end 132A. Correspondingly, the inlet channel 21A of each flow channel system 20A is located in the middle section of the tool combination section 13A to connect the water inlet groove 133A, and the length of the corresponding main channel 22A is also shortened, and the position of the corresponding branch channel 23A is roughly the same. In other words, the technical means provided by the present invention can be applied to different types of tool handles, and can achieve the effect of enhanced cooling water outlet.

The above is only the preferred embodiment of the present invention and does not limit the present invention in any form.
