[0024] 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.

[0025] Example 1:

[0026] Referring to Figures 1-6, a quick-connect structure for a cutting tool includes a tool holder 1. A connecting groove 2 is formed at the bottom of the tool holder 1. Limiting grooves 3 are formed on both sides of the connecting groove 2. A connecting block 4 is slidably connected inside the connecting groove 2. The diameter of the connecting block 4 is the same as the diameter of the connecting groove 2, and the connecting block 4 is tightly fitted to the inner wall of the connecting groove 2. Limiting blocks 5 are fixedly connected to both sides of the connecting block 4. The shape and size of the limiting blocks 5 are the same as the shape and size of the limiting grooves 3, and the limiting blocks 5 are tightly fitted to the inner walls of the limiting grooves 3. A threaded groove 8 is formed at the top of the connecting block 4. A mounting base 6 is fixedly connected to the bottom of the tool holder 4. A cutting head 7 is fixedly connected to the bottom of the mounting base 6. A threaded hole 9 is opened at the top of the tool holder 1. A threaded rod 10 is threadedly connected inside the threaded hole 9. The threaded hole 9 passes through the top wall of the tool holder 1 and communicates with the connecting groove 2. The threaded rod 10 extends through the threaded hole 9 into the inside of the threaded groove 8. A knob 11 is fixedly connected to the top of the threaded rod 10. A mounting ring 12 is fixedly connected to the middle of the surface of the tool holder 1. A limit spring 13 is fixedly connected to the top of the mounting ring 12. A sliding sleeve 14 is fixedly connected to the top of the limit spring 13.

[0027] Working principle: When using the tool, if the operator needs to connect the tool head 7 to the tool holder 1, simply align the connecting block 4 on the tool head 7 with the connecting groove 2 on the tool holder 1 and insert it, so that the limiting blocks 5 on both sides of the connecting block 4 are inserted into the corresponding limiting grooves 3. At this time, the operator pulls down the sliding sleeve 14 to expose the knob 11. The operator then rotates the knob 11, which in turn drives the threaded rod 10 to rotate. The rotation of the threaded rod 10 will screw into the threaded groove 8 of the connecting block 4 through the threaded hole 9, thereby locking the position of the connecting block 4. This achieves quick connection of the tool, is simple to operate, improves work efficiency, and is convenient for operators to use.

[0028] Compared with related technologies, the quick-connect structure for cutting tools provided by this utility model has the following advantages: by setting a connecting block 4, a connecting groove 2, etc., in conjunction with a threaded rod 10, the cutting head 7 and the cutting handle 1 can be quickly connected by inserting the connecting block 4 into the connecting groove 2. The position of the connecting block 4 can be locked by rotating the threaded rod 10 to extend into the threaded groove 8 at the top of the connecting block 4. The operation is simple, the work efficiency is improved, and it is convenient for workers to use.

[0029] Example 2:

[0030] Referring to Figures 1-7, the top of the tool holder 1 has a threaded hole 9, and a threaded rod 10 is threadedly connected inside the threaded hole 9. A knob 11 is fixedly connected to the top of the threaded rod 10. The diameter of the knob 11 is the same as that of the tool holder 1, and the knob 11 fits tightly against the top of the tool holder 1. A mounting ring 12 is fixedly connected to the middle of the surface of the tool holder 1. A limit spring 13 is fixedly connected to the top of the mounting ring 12. A sliding sleeve 14 is fixedly connected to the top of the limit spring 13. The inner diameter of the sliding sleeve 14 is the same as that of the tool holder 1, and the sliding sleeve 14 fits tightly against the surface of the tool holder 1.

[0031] Working principle: When the knob 11 drives the threaded rod 10 to extend into the threaded groove 8 and lock the connecting block 4, the operator can release the sliding sleeve 14. At this time, the limit spring 13 loses the influence of external force and returns to its original position. After the limit spring 13 is reset, it will push the sliding sleeve 14 to move upward along the tool holder 1, thereby completely wrapping the knob 11 inside the sliding sleeve 14, thus protecting the knob 11 and preventing the knob 11 from rotating due to external force, which could cause the threaded rod 10 to loosen and affect the stability of the connecting block 4, making it easy to use.

[0032] Compared with related technologies, the quick-connect structure for cutting tools provided by this utility model has the following advantages: by setting up a sliding sleeve 14, a tool holder 1, a limiting spring 13, etc., in conjunction with the knob 11, the limiting spring 13 pushes the sliding sleeve 14 to move upward along the tool holder 1, thereby completely enclosing the knob 11 inside the sliding sleeve 14, thus protecting the knob 11 and preventing the knob 11 from rotating due to external forces, which could cause the threaded rod 10 to loosen and affect the stability of the connecting block 4, making it convenient to use.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
