[0019] 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.

[0020] Example 1

[0021] Please see Figure 1-2A deburring and chamfering knife adaptable to different hole diameters includes a knife body 1. The end of the knife body 1 can be mounted on an electric handle. A storage groove 2 is provided near the bottom of the knife body 1. A rotating chamfering knife 5 is provided in the storage groove 2. The rotation axis of the chamfering knife 5 is parallel to but does not coincide with the axis of the knife body 1. When the electric handle drives the knife body 1 to rotate, the chamfering knife 5 is in an unfolded state due to centrifugal force, thereby enabling chamfering and deburring of the inner hole.

[0022] The maximum unfolding angle of the chamfering cutter 5 relative to the storage slot 2 is controlled by an adjustment mechanism. When the chamfering cutter 5 is performing chamfering, it is at its maximum unfolding angle. When the chamfering cutter 5 is pulled out of the inner hole, it folds back into the storage slot 2. The maximum unfolding angle of the chamfering cutter 5 relative to the storage slot 2 is controlled because different unfolding angles allow it to adapt to holes of different diameters, thus providing a wide range of adaptability. When the chamfering cutter 5 unfolds, the trajectory of its end is as follows... Figure 3 The dashed line in the middle indicates this.

[0023] The chamfering cutter 5 is detachably mounted on the cutter holder 4, which is fixed to the rotating shaft 3. The rotating shaft 3 is rotatably mounted on the inner wall of the storage slot 2. The back of the cutter holder 4 is arc-shaped, ensuring that the back of the cutter holder 4 does not protrude beyond the storage slot 2 when the chamfering cutter 5 is folded into it. The chamfering cutter 5 is a consumable part that needs frequent replacement; therefore, it is designed to be detachable. The fact that the back of the cutter holder 4 does not protrude beyond the storage slot 2 when folded allows the cutter body 1 to freely pass through the hole.

[0024] The adjustment mechanism consists of a spline tooth 12 and a spline groove 11. The spline groove 11 is located on the top of the cutter body 1. The top of the rotating shaft 3 passes through the bottom of the spline groove 11. The top of the rotating shaft 3 fixes the spline tooth 12, and the spline tooth 12 is inserted into the spline groove 11.

[0025] The top of the spline tooth 12 is provided with a pull-out groove 13. Inserting a flathead screwdriver into the pull-out groove 13 can pull the spline tooth 12 out of the spline groove 11, thereby changing the angle of the chamfering tool 5.

[0026] The tool holder 4 and the chamfering tool 5 have clearance openings 14 at their respective ends. The clearance openings 14 ensure that the tool holder 4 does not interfere with the deburring movement of the chamfering tool 5.

[0027] Example 2

[0028] Please see Figure 3 and 5 A deburring and chamfering knife adaptable to different hole diameters includes a knife body 1. The end of the knife body 1 can be mounted on an electric handle. A storage groove 2 is provided near the bottom of the knife body 1. A rotating chamfering knife 5 is provided in the storage groove 2. The rotation axis of the chamfering knife 5 is parallel to but does not coincide with the axis of the knife body 1. When the electric handle drives the knife body 1 to rotate, the chamfering knife 5 is in an unfolded state due to centrifugal force, thereby enabling chamfering and deburring of the inner hole.

[0029] The maximum unfolding angle of the chamfering cutter 5 relative to the storage slot 2 is controlled by an adjustment mechanism. When the chamfering cutter 5 is performing chamfering, it is at its maximum unfolding angle. When the chamfering cutter 5 is pulled out of the inner hole, it folds back into the storage slot 2. The maximum unfolding angle of the chamfering cutter 5 relative to the storage slot 2 is controlled because different unfolding angles allow it to adapt to holes of different diameters, thus providing a wide range of adaptability. When the chamfering cutter 5 unfolds, the trajectory of its end is as follows... Figure 3 The dashed line in the middle indicates this.

[0030] The chamfering cutter 5 is detachably mounted on the cutter holder 4, which is fixed to the rotating shaft 3. The rotating shaft 3 is rotatably mounted on the inner wall of the storage slot 2. The back of the cutter holder 4 is arc-shaped, ensuring that the back of the cutter holder 4 does not protrude beyond the storage slot 2 when the chamfering cutter 5 is folded into it. The chamfering cutter 5 is a consumable part that needs frequent replacement; therefore, it is designed to be detachable. The fact that the back of the cutter holder 4 does not protrude beyond the storage slot 2 when folded allows the cutter body 1 to freely pass through the hole.

[0031] The adjustment mechanism consists of a torsion spring 10 and a limiting member 8. One end of the rotating shaft 3 is rotated by the damping of the torsion spring 10 and the blade body 1. The other end of the rotating shaft 3 is connected to the limiting member 8. The angle of the limiting member 8 is adjustable. A limiting strip 16 is provided inside the rotating shaft 3. The limiting member 8 and the limiting strip 16 abut against each other to control the maximum rotation angle of the rotating shaft 3.

[0032] The limiting member 8 is inserted into a screw hole 6 at the bottom or top of the cutter body 1. An arc-shaped groove 15 is provided at the bottom of the screw hole 6. A retaining strip 9 is provided on the limiting member 8, passing through the arc-shaped groove 15 and inserted into the rotating shaft 3. A screw 7 is screwed into the screw hole 6, pressing the limiting member 8. Adjusting the rotation angle of the limiting member 8 controls the maximum unfolding angle of the chamfering cutter 5, thus allowing the chamfering cutter 5 to adapt to a wider range of hole diameters. This enables the processing of holes with large size differences, eliminating the need for frequent tool changes and improving processing efficiency.

[0033] The tool holder 4 and the chamfering tool 5 have clearance openings 14 at their respective ends. The clearance openings 14 ensure that the tool holder 4 does not interfere with the deburring movement of the chamfering tool 5.
