[0019] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0020] Reference Figure 1-5 As shown, a positioning structure for a copper-clad laminate cutting tool includes a tool disk 1 and a connecting shaft 3 disposed on one side of the tool disk 1. One end of the connecting shaft 3 is detachably connected to the tool disk 1 through a quick-connect structure, and the other end of the connecting shaft 3 is fixed to the output end of a motor.

[0021] By using a quick-installation structure to replace the traditional flange installation, the connection between the tool disc 1 and the connecting shaft 3 is ensured to be firm, while significantly improving the ease of disassembly and assembly of the tool disc 1.

[0022] Specifically, refer to Figure 1-4As shown, it is worth noting that the quick-release structure includes a mounting plate 2 fixed to the end of the connecting shaft 3. Several positioning holes are circumferentially opened on the mounting plate 2, and positioning pins 4 that are fixed to the tool disk 1 are inserted into the positioning holes.

[0023] By setting the positioning hole and positioning post 4, when the tool disc 1 is assembled on the end of the connecting shaft 3, the rotation axis of the tool disc 1 coincides with the connecting shaft 3. Thus, the tool disc 1 can maintain a stable cutting path during the cutting process, avoid cutting deviation, and ensure the processing accuracy and consistency of the product.

[0024] Furthermore, referring to Figure 3-5 As shown, it is worth noting that the rod body of the connecting shaft 3 is equipped with a multi-directional plug-in assembly for synchronously locking several positioning pins 4;

[0025] The multi-directional plug-in assembly includes a movable ring plate 5 that is rotatably connected to the surface of the mounting plate 2 and several positioning pieces 6 that are fixed around the outer wall of the movable ring plate 5. The rod of the positioning post 4 has a positioning notch that matches the positioning piece 6.

[0026] By using the multi-directional plug-in assembly, the movable ring plate 5 can be easily rotated so that several positioning pieces 6 can be simultaneously deflected out of the positioning notches of the corresponding positioning posts 4, thereby unlocking several positioning posts 4 and facilitating the disassembly of the tool disc 1. Similarly, the movable ring plate 5 can be easily reversed so that several positioning pieces 6 can be simultaneously rotated into the corresponding positioning notches, thereby quickly fixing several positioning posts 4 and achieving rapid installation of the tool disc 1.

[0027] Furthermore, referring to Figure 3 As shown, it is worth noting that a toggle block 7 is provided on the side of the mounting plate 2 away from the tool plate 1, and the toggle block 7 is fixedly connected to the movable ring plate 5 through a bracket.

[0028] By setting the toggle block 7, pushing and pulling the toggle block 7 makes it convenient to manually control the rotation of the movable ring plate 5.

[0029] Furthermore, referring to Figure 4 and Figure 5 As shown, it is worth noting that a buffer groove is provided in the inner wall of the toggle block 7, and a plug-in component is placed inside the buffer groove. A pressing component that cooperates with the plug-in component is provided on the toggle block 7.

[0030] The plug-in component includes a plug-in rod 8 that slides in the buffer groove and a locking notch opened on the mounting plate 2. One end of the plug-in rod 8 is inserted into the locking notch, and a return spring 9 is fixed between the other end of the plug-in rod 8 and the innermost inner wall of the buffer groove.

[0031] The pressing component is a pressing screw 11, which is located outside the actuating block 7. The plug rod 8 has a pressure notch 10 with a right-angled trapezoidal cross section. One end of the pressing screw 11 is threaded into the buffer groove and abuts against the inclined inner wall of the pressure notch 10.

[0032] By setting up the pressing component and the plugging component, when the movable ring plate 5 is rotated and the positioning piece 6 is turned into the positioning notch, the plugging rod 8 moves to the position of the corresponding locking notch along with the actuating block 7. The plugging rod 8 can then be inserted into the locking notch under the elastic force of the return spring 9, locking the actuating block 7, the movable ring plate 5 and the positioning piece 6 as a whole, ensuring the firmness of the positioning piece 6 in the positioning notch and maintaining its locking effect on the positioning post 4.

[0033] Subsequently, simply rotate the knob to press the screw 11, causing it to pass into the buffer groove under the thread structure and continuously press the pressure notch 10 obliquely towards the inner wall, causing the plug rod 8 to contract under force and the buffer groove to exit from the locking notch, thereby releasing the overall fixation of the toggle block 7 and the movable ring plate 5, making it convenient for manual secondary rotation of the movable ring plate 5.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
