[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Refer to Figures 1-5 , an adjustable chamfering tool in an embodiment of the present invention includes a handle body 1 and a knife storage body 5. The knife storage body 5 is arranged inside the handle body 1. A limit ring 7 is arranged at the top of the knife storage body 5. A tool body 4 is arranged at the bottom of the knife storage body 5. A connecting ring 11 is arranged at the top of the limit ring 7. Positioning grooves 9 are arranged on the peripheral surfaces of the bottom of the handle body 1. A positioning ring 3 is arranged on the outer surface of the lower part of the knife storage body 5. Positioning strips 8 are arranged on the peripheral surfaces of the top of the positioning ring 3. Limit grooves 2 are arranged on the outer surfaces of both sides of the handle body 1. An adjusting ring 6 and a threaded body 10 are arranged on the outer surface of the upper part of the knife storage body 5.

[0024] The handle body 1 is made of aluminum alloy with an annular structure, and the storage knife body 5 is made of aluminum alloy with a cylindrical structure. The storage knife body 5 is in a limited rotational connection with the inside of the handle body 1. By setting the storage knife body 5, a fixed state can be provided for the tool body 4 to ensure the stability of the machining of the tool body 4. The limiting ring 7 is fixedly connected to the top of the storage knife body 5 by threads. The top surface of the limiting ring 7 is fixedly in contact with the connecting ring 11. By setting the limiting ring 7, the separation between the adjusting ring 6 and the storage knife body 5 can be avoided. At the same time, the adjusting ring 6 can also be in a separated state between the storage knife bodies 5, which is convenient for the storage knife body 5 to drive the tool body 4 to separate from the inside of the handle body 1 later, so as to facilitate the replacement of the tool body 4. The tool body 4 is usually made of high-speed steel or cemented carbide. The periphery of the tool body 4 has an irregular concave structure. The tool body 4 is fixedly in contact with the bottom of the storage knife body 5. The tool body 4 is in contact and rotational connection with the inside of the handle body 1 through the storage knife body 5. By setting the tool body 4, with the tool body 4 having an irregular concave structure on all sides, the tool body 4 can have different chamfer sizes for mechanical operations. The peripheral surfaces at the bottom of the handle body 1 are all fitted and recessed with the positioning card slots 9. The peripheral surfaces at the top of the positioning ring 3 are all fixedly in contact with the positioning strips 8. The positioning ring 3 is made of aluminum alloy with an annular structure. By setting the positioning card slots 9 and the positioning strips 8, the deviation of the chamfer cutting angle caused by the rotation of the storage knife body 5 in the handle body 1 can be avoided for the tool body 4. The positioning ring 3 is fixedly connected to the outer surface below the storage knife body 5. The positioning ring 3 forms a snap-fit positioning connection with the bottom of the handle body 1 through the snap-fit connection between the positioning strip 8 and the positioning card slot 9. The storage knife body 5 forms a snap-fit fixed contact effect with the inside of the handle body 1 through the positioning ring 3, the positioning card slot 9 and the positioning strip 8. The outer surfaces on both sides of the handle body 1 are all fitted and recessed with the limiting grooves 2. The surface of the limiting grooves 2 is made of a polyurethane coating. By setting the limiting grooves 2, a holding space can be provided for the stable holding of the handle body 1 to ensure the stable state of the handle body 1 during the movement. The threaded body 10 is fixedly in contact with the outer surface above the storage knife body 5. The adjusting ring 6 is in contact connection with the upper part of the handle body 1 through the threaded connection between the threaded bodies 10.

[0025] Working principle: The connecting ring 11 at the top of the limit ring 7 is driven by mechanical means to drive the tool body 4 at the bottom to perform chamfering cutting on the surface of the mechanical object. The handle body 1 is held by the limit groove 2, ensuring the overall stability and adjustment performance of the handle body 1 of the chamfering tool during the mechanical pushing process. Later, by adjusting the loosening effect of the thread between the adjusting ring 6 and the threaded body 10, the tool body 4 moves downward from the storage tool body 5 to the handle body 1, realizing the detachment of the positioning strip 8 from the positioning slot 9, achieving the chamfering adjustment cutting state of the irregular concave structure around the tool body 4 on the mechanical surface. Then, the positioning strip 8 and the positioning slot 9 are engaged and connected again, and fixed by rotating the threaded body 10 on the surface of the adjusting ring 6 and the storage tool body 5, so that the tool body 4 maintains a stable state.

[0026] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
