[0021] 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.

[0022] Please see Figure 1 - Figure 6 An adjustable carbon fiber tenon cutter includes a main body 1. The top of the main body 1 has a mounting cavity 2. A telescopic block 3 is slidably connected to the inner wall of the main body 1. A threaded rod 4 and a sprocket 5 are rotatably connected to the inner wall of the main body 1. A rotating head 6 is fixedly installed at the bottom of the sprocket 5. A chain 7 is rotatably sleeved on the outer wall of the sprocket 5. A limit block 8 is fixedly installed on the outer wall of the telescopic block 3. A limit groove 9 is formed on the inner wall of the telescopic block 3. A scale 10 is fixedly installed at the bottom of the telescopic block 3. A cutting head 11 is provided on the outer wall of the telescopic block 3. An insertion block 12 is fixedly installed on the outer wall of the cutting head 11. A threaded rod 14 is rotatably connected to the inner wall of the telescopic block 3. A pin 13 is slidably connected to the inner wall of the telescopic block 3. A threaded groove 15 is formed at the top of the pin 13. A worm gear 16 is fixedly installed at the end of the threaded rod 4 away from the telescopic block 3. A connecting rod 18 is fixedly installed at the top of the sprocket 5. A worm gear 17 is fixedly installed at the top of the connecting rod 18.

[0023] In the above structure, the limiting block 8 is limited by the limiting groove 9, which in turn limits the telescopic block 3. When the telescopic block 3 moves, it drives the limiting block 8 to move on the inner wall of the limiting groove 9, so that the limiting block 8 cannot detach from the limiting groove 9, and the telescopic block 3 cannot detach from the main body 1.

[0024] In a preferred embodiment: the threaded groove 15 passes through the pin 13, and the bottom of the threaded rod 14 extends to the inner wall of the threaded groove 15, and the bottom of the threaded rod 14 is threadedly connected to the threaded groove 15.

[0025] In the above structure, by rotating the threaded rod 14, the threaded rod 14 drives the threaded groove 15 to move through the threaded connection with the threaded groove 15, thereby allowing the threaded rod 14 to drive the threaded groove 15 to move up and down on the inner wall of the telescopic block 3.

[0026] In a preferred embodiment, the height of the worm 17 is the same as that of the worm wheel 16, and the worm 17 and the worm wheel 16 mesh with each other.

[0027] In the above structure, by rotating the connecting rod 18, the connecting rod 18 drives the worm 17 to rotate. At this time, the worm 17 rotates outside the worm wheel 16, and the worm 17 drives the worm wheel 16 to rotate through meshing with the worm wheel 16, which in turn drives the threaded rod 4 to rotate.

[0028] In a preferred embodiment, the end of the threaded rod 4 away from the worm gear 16 extends to the inner wall of the telescopic block 3, and the worm gear 16 is threadedly connected to the inner wall of the telescopic block 3.

[0029] In the above structure, when the threaded rod 4 rotates, one end of it located on the inner wall of the telescopic block 3 rotates, thereby causing the threaded rod 4 to drive the telescopic block 3 to move through the threaded connection with the telescopic block 3, which in turn causes the telescopic block 3 to drive the cutter head 11 to move.

[0030] In a preferred embodiment: there are three telescopic blocks 3, threaded rod 4, sprocket 5, rotating head 6, connecting rod 18, worm 17 and worm wheel 16, and the three telescopic blocks 3, threaded rod 4, sprocket 5, rotating head 6, connecting rod 18, worm 17 and worm wheel 16 are arranged in a circular array on the inner wall of the main body 1. There are two chains 7, and the two chains 7 connect the three sprockets 5.

[0031] In the above structure, by rotating the rotating head 6, the rotating head 6 drives the sprocket 5 to rotate, the sprocket 5 drives the two chains 7 to rotate, the two chains 7 drive the three sprockets 5 to rotate respectively, the three sprockets 5 drive the three connecting rods 18 to rotate, and the three connecting rods 18 drive the three worm gears 17 to rotate.

[0032] In a preferred embodiment, the bottom dimension of the pin 13 is the same as the inner wall dimension of the insertion block 12, and the pin 13 is located in the inner wall of the insertion block 12.

[0033] In the above structure, by inserting the insertion block 12 into the inner wall of the telescopic block 3, the inner wall of the insertion block 12 reaches the bottom of the pin 13. At this time, the pin 13 is moved downward, thereby fixing the inner wall of the insertion block 12, fixing the insertion block 12 to the inner wall of the telescopic block 3, and thus fixing the blade head 11.

[0034] Working Principle: When using this equipment, the mounting cavity 2 is connected to the rotating shaft, which in turn causes the entire equipment to rotate. The rotation of the telescopic block 3 drives the cutter head 11 to rotate, cutting the wood. When the position of the cutter head 11 needs to be adjusted, the rotating head 6 is rotated, which in turn drives the sprocket 5 to rotate. The sprocket 5 drives two chains 7 to rotate, which in turn drives three sprockets 5 to rotate. The three sprockets 5 then drive three connecting rods 18 to rotate, which in turn drive three worm gears 17 to rotate. The rotation of the three worm gears 17 drives three worm wheels 16 to rotate, which in turn drive three threaded... Rotating rod 4 causes the three telescopic blocks 3 to slide on the inner wall of the main body 1, thereby moving the cutter head 11 and changing its position. When the cutter head 11 needs to be replaced individually, rotating threaded rod 14 causes the threaded groove 15 to move upward through its threaded connection with the threaded groove 15. This causes the threaded groove 15 to move the pin 13 upward, disengaging the pin 13 from the inner wall of the insertion block 12. At this point, the fixing relationship of the insertion block 12 disappears, and the cutter head 11 is pulled out, causing the cutter head 11 to pull the insertion block 12 away from the inner wall of the telescopic block 3.

[0035] 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.
