[0031] With reference to Figures 1-2 The utility model provides an embodiment: a variable angle ceramic cutting tool, including handle 1, the right end fixed connection of handle 1 has the adjusting circular platform 2, the upper portion of adjusting circular platform 2 is provided with adjusting disc 3, the size of adjusting disc 3 and the size of adjusting circular platform 2 are mutually adapted, adjusting disc 3 outside is provided with connecting unit, connecting unit includes bolt 31 and screw hole 32, bolt 31 sets up in the upper portion of adjusting disc 3, screw hole 32 is set up in the upper surface center of adjusting circular platform 2, the size of bolt 31 and the size of screw hole 32 are mutually adapted, the bottom end of bolt 31 is penetrated in adjusting disc 3, and bolt 31 is inserted between adjusting disc 3, and the bottom end of bolt 31 is connected between screw hole 32, and staff can be fixed adjusting disc 3 by screwing bolt 31 into screw hole 32, when staff screw bolt 31 and move up, the limiting of adjusting disc 3 is removed, adjusting disc 3 can be linear motion and rotation in the up-down direction relative to bolt 31, the right side surface of adjusting disc 3 is fixedly connected with mounting block 4, and the right side of mounting block 4 is detachably connected with blade 5, when adjusting disc 3 is rotated and adjusted, can drive blade 5 to carry out angle adjustment simultaneously through mounting block 4, so that the adaptability and flexibility of the tool are improved.

[0032] The upper surface of adjusting circular platform 2 is fixedly connected with annular adjusting tooth group 6, and the annular adjusting tooth group 6 is fixedly connected to the upper surface of the adjusting circular platform 2 in a ring array by a plurality of annular adjusting teeth. The bottom surface of the adjusting disc 3 is provided with an annular tooth groove group 7, and the annular tooth groove group 7 is provided on the bottom surface of the adjusting disc 3 in a ring array by a plurality of annular tooth grooves. The annular adjusting tooth group 6 and the annular tooth groove group 7 are adapted to each other. After the adjusting disc 3 is rotated and adjusted, the adjusting disc 3 is pressed down, so that the annular adjusting tooth group 6 is inserted into the annular tooth groove group 7 to limit the adjusting disc 3. Then, the bolt 31 is screwed to fix the adjusting disc 3, so that the blade 5 can be used stably.

[0033] With reference to Figures 2-4The outer side of the adjusting disc 3 is fixedly connected with a protective cover 8. The adjusting disc 3 moves to drive the protective cover 8 to move synchronously. The size of the protective cover 8 is matched with the size of the adjusting circular table 2. When the adjusting disc 3 moves downward to be fixed, the protective cover 8 is inserted into the outer side of the adjusting circular table 2. At this time, the protective cover 8 can shield the outer side of the annular adjusting tooth group 6. The outer side surface of the adjusting circular table 2 is provided with an annular groove 9. The inner bottom surface of the annular groove 9 is fixedly connected with an annular air bag 10. The upper side of the annular air bag 10 is provided with an annular plate 11. The inner walls of the annular air bag 10 and the annular plate 11 are matched with the inner wall of the annular groove 9. The outer wall diameter of the annular air bag 10 is matched with the diameter of the adjusting circular table 2. The diameter of the annular plate 11 is smaller than the diameter of the adjusting circular table 2.

[0034] When the annular plate 11 moves downward, the annular air bag 10 is extruded. Since the inner wall of the annular air bag 10 is limited by the inner wall of the annular groove 9, the annular air bag 10 is rapidly expanded outward. At this time, the annular air bag 10 can seal and fill the gap between the protective cover 8 and the adjusting circular table 2, improve the sealing and protection effect of the outer side of the annular adjusting tooth group 6, avoid the cooling liquid in the cutting process from carrying the cutting scraps into the cutter, and affect the use of the cutter. The upper surface of the annular plate 11 is fixedly connected with a push rod 12. The top end of the push rod 12 penetrates the adjusting circular table 2. The push rod 12 moves to drive the annular plate 11 to move synchronously. The push rod 12 is inserted into the adjusting circular table 2. The adjusting circular table 2 can limit the movement of the push rod 12. The push rod 12 can only move in the straight line direction.

[0035] Referring to Figures 3-4 The top end of the push rod 12 is fixedly connected with a sliding block 13. The sliding block 13 moves to drive the push rod 12 to move synchronously. The inner top surface of the adjusting disc 3 is provided with an annular sliding groove 14. The sliding block 13 is slidingly connected with the inner part of the annular sliding groove 14. The sliding block 13 can rotate and move along the path of the annular sliding groove 14 in the inner part of the annular sliding groove 14. Thus, the push rod 12 and the sliding block 13 and other structures arranged in the process of rotating and adjusting the adjusting disc 3 will not hinder the movement of the adjusting disc 3. The upper surface of the adjusting disc 3 is provided with a scale 15. The staff can accurately control the adjustment angle of the blade 5 through the scale 15.

[0036] When the staff moves the adjusting disc 3 upward, the sliding block 13 and the push rod 12 drive the annular plate 11 to move upward synchronously. When the annular plate 11 moves to the upper surface of the annular groove 9 and cannot move any more, the annular adjusting tooth group 6 is completely separated from the annular tooth groove group 7. At this time, the staff can rotate the adjusting disc 3 to adjust the angle of the blade 5. The staff can clearly understand the separation time between the annular adjusting tooth group 6 and the annular tooth groove group 7. The annular tooth groove group 7 is prevented from being rotated and adjusted without leaving the annular adjusting tooth group 6, which causes the annular adjusting tooth group 6 and the annular tooth groove group 7 to be damaged.

[0037] When the worker drives the adjusting disc 3 to reset downward, the ring-shaped plate 11 will be driven to reset synchronously through the sliding block 13 and the push rod 12, when the ring-shaped plate 11 is attached to the ring-shaped air bag 10, the protective cover 8 will pass through the ring-shaped air bag 10 completely, when the adjusting disc 3 is reset to the ring-shaped adjusting tooth group 6 completely entering the inside of the ring-shaped tooth groove group 7, the bottom surface of the protective cover 8 will be lower than the ring-shaped air bag 10, at this time, the ring-shaped plate 11 will also extrude the ring-shaped air bag 10, so that the ring-shaped air bag 10 is deformed, further filling and sealing the gap between the adjusting disc 2 and the protective cover 8, ensuring the sealing and protection effect of the ring-shaped adjusting tooth group 6.

[0038] Working principle: when the angle of the blade 5 needs to be adjusted, the bolt 31 is screwed upward to release the limiting of the adjusting disc 3, then the adjusting disc 3 is lifted to drive the ring-shaped tooth groove group 7 to separate from the ring-shaped adjusting tooth group 6, at the same time, the ring-shaped plate 11 is driven to move upward synchronously through the sliding block 13 and the push rod 12, when the ring-shaped plate 11 moves to the upper surface of the ring-shaped groove 9 and is attached to each other, the pulling is stopped, at this time, the limiting of the adjusting disc 3 is completely released, at this time, the worker can adjust the adjusting disc 3, when the blade 5 is adjusted to the required angle, the adjusting disc 3 is pressed downward to reset, so that the ring-shaped adjusting tooth group 6 is completely inserted into the inside of the ring-shaped tooth groove group 7, in this process, the protective cover 8 will move to the outside of the adjusting disc 2 to protect the ring-shaped adjusting tooth group 6, at the same time, the ring-shaped plate 11 will extrude the ring-shaped air bag 10, so that the ring-shaped air bag 10 is deformed to the protective cover 8, filling the gap between the protective cover 8 and the adjusting disc 2, further improving the sealing and protection effect of the ring-shaped adjusting tooth group 6, avoiding the cooling liquid and the cutting chips entering the inside of the tool during cutting, affecting the use of the tool.

[0039] Finally, it should be noted that: the above only describes the preferred embodiments of the present application, and is not intended to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application, should be included in the protection scope of the present application.
