[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. Example

[0020] Please see Figure 1 This embodiment provides a diamond CNC cutting tool that is easy to assemble and replace, including a support column 1 and at least two cutting blades 3. A through hole 8 is laterally opened on the right side of the support column 1. A connecting rod 4 is slidably inserted into the through hole 8, and the right end of the connecting rod 4 extends to the outside of the through hole 8. The cutting blade 3 is slidably inserted into the outside of the connecting rod 4 and near its right end. A positioning plate 5 is provided on the connecting rod 4 corresponding to the cutting blade 3, and the right positioning plate 5 is fixed on the connecting rod 4. Other positioning plates 5 are slidably connected to the connecting rod 4. A positioning groove 10 is opened on the right side of the cutting blade 3, and the positioning plate 5 is slidably connected in the positioning groove 10. At least two cutting blades 3 abut against each other, and the left cutting blade 3 abuts against the right side of the support column 1. A rotation area 9 is formed on the left side of the positioning plate 5, and the cutting blade 3 is located in the rotation area 9. A positioning unit is provided on the connecting rod 4.

[0021] In application, the positioning unit loosens the restriction on the connecting rod 4, allowing the connecting rod 4 to move within the through hole 8. After the connecting rod 4 moves to the right, the positioning plate 5, which is movably mounted on the connecting rod 4, can move on the connecting rod 4. After its movement, the positioning plate 5 can also move out of the positioning groove 10. As the positioning plate 5 moves on the connecting rod 4, the size of the rotating area 9 can also be adjusted, and the blade 3 can also move into the rotating area 9. After the blade 3 enters the rotating area 9, the blade 3 can rotate on the connecting rod 4. When the blade 3 rotates, a suitable blade 3 can be selected according to the usage requirements, and the blade 3 is positioned with its tip facing down. At this point, the blade 3 is replaced. Afterward, the positioning unit moves the connecting rod 4 to the left, and the positioning plate 5 moves into the corresponding positioning groove 10. The blades 3 also abut against each other and finally abut against the right side of the support column 1, thus completing the replacement of the blade 3. Example

[0022] The basic content is from Example 1, the difference being:

[0023] Please see Figure 1-3In this embodiment, the other positioning plates 5 move laterally on the connecting rod 4. The blade 3 has a rotating hole through which the connecting rod 4 passes. The positioning groove 10 is connected to the rotating hole. The other positioning plates 5 have through holes through which the connecting rod 4 passes. The outer side of the connecting rod 4 has a sliding groove 11 along its length. A slider 12 is fixed longitudinally in the through hole. The slider 12 is slidably connected in the sliding groove 11. The connecting rod 4 moves laterally in the through hole 8. The width of the slider 12 is adapted to the width of the inner cavity of the sliding groove 11.

[0024] In application, after the connecting rod 4 is released from its restriction, the positioning plate 5, which is movably set on the connecting rod 4, can move on the connecting rod 4, and the slider 12 also moves in the slide groove 11 to adjust the distance of the rotation area 9 so that the blade 3 can rotate on the connecting rod 4. After the blade 3 has rotated, the positioning plate 5, which is movably set on the connecting rod 4, is connected to the positioning plate 5 to restrict the blade 3 and prevent it from rotating. Example

[0025] The basic content is from Example 1, the difference being:

[0026] Please see Figure 2 In this embodiment, the positioning unit includes a stud 2, a threaded hole 7 is provided on the left side of the support column 1, and the threaded hole 7 is connected to the through hole 8. The left end of the connecting rod 4 extends into the threaded hole 7 and is rotatably connected to the right side of the stud 2 through a bearing. A hexagonal square hole 6 is provided on the left side of the stud 2.

[0027] In application, when moving the connecting rod 4, the hexagonal wrench is connected to the hexagonal square hole 6, which allows the stud 2 to rotate in the threaded hole 7. The stud 2 will also move in the threaded hole 7, and when it moves, it will also drive the connecting rod 4 to move. After the stud 2 drives the connecting rod 4 to move to the right, the blade 3 can be rotated to determine the appropriate blade 3. After the determination is completed, the stud 2 drives the connecting rod 4 to move to the left, which allows the blades 3 to abut against each other and against the support column 1.

[0028] 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.
