[0017] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Example 1: Please refer to Figures 1-3 This is the first embodiment of the present invention, which provides a double-edged symmetrical dovetail cutter, comprising: Connecting seat 1, shaft 2, connecting head 5, with shaft 2 installed inside the connecting seat 1; Connector 5 is fixed to the top of shaft 2; Connecting component 3, fixing component 4, and mounting component 6; The connecting component 3 is located inside the connecting base 1; Fixing component 4 is located at the bottom inner side of shaft 2; Mounting component 6 is located on the side of connector 5.

[0020] Specifically, the connecting component 3 includes a mounting groove 31, a limiting groove 32, a limiting block 33, a fixing seat 34, a fixing hole 35, a cutting blade 36, a through hole 37, and a screw 38. The mounting groove 31 is opened inside the connecting seat 1. The limiting groove 32 is opened inside the mounting groove 31. The shaft 2 is slidably installed inside the limiting groove 32 through the limiting block 33. The fixing seats 34 are symmetrically fixed on the two circumferential surfaces of the connecting seat 1. The cutting blade 36 is fastened inside the fixing seat 34. The fixing holes 35 are symmetrically opened on the side of the fixing seat 34. The through holes 37 are evenly opened on the side of the cutting blade 36. The screw 38 is rotatably inserted into the fixing hole 35 and the through hole 37.

[0021] Furthermore, by using screw 38 to engage with mounting base 34, the blade can be removed from the inside of mounting base 34 for replacement when it is damaged, thus reducing the cost of blade replacement and making it easier to use through the modular structure.

[0022] In use, the cutting blade 36 is fixedly installed inside the fixed seat 34 with the help of the screw 38. The shaft 2 is connected to the connecting seat 1 through the cooperation of the limiting groove 32 and the limiting block 33. The shaft 2 can drive the connecting seat 1 to rotate. Before and after use, the connecting seat 1 can be removed from one end of the shaft 2 as needed, so that the operator can easily grind and maintain the cutting blade 36 fixed on its circumference. When the blade is damaged or worn, the cutting blade 36 can be removed and replaced separately, thereby reducing the maintenance cost of the dovetail cutter and making it easier to use.

[0023] In summary, through the structure of the connecting component 3, the connecting seat 1 and the shaft 2 can be connected by the limiting groove 32 and the limiting block 33. This allows the shaft 2 to rotate the cutting blades 36 symmetrically arranged on both sides of the connecting seat 1 under the cooperation of the connecting seat 1, thereby performing cutting operations. During use, the screw 38 can be turned to remove the cutting blades 36 inside the fixing seat 34, thus allowing the blades to be replaced when damaged, reducing the maintenance and replacement costs of the blades and making them easier to use.

[0024] Example 2: Please refer to Figures 4-5 This is the second embodiment of the present utility model.

[0025] Specifically, the fixing component 4 includes a sliding groove 41, a fixing rod 42, a spring 43, and a fixing groove 44. The sliding groove 41 is symmetrically opened on the bottom circumferential surface of the shaft 2. The fixing rod 42 is slidably installed inside the sliding groove 41. The fixing groove 44 is symmetrically opened at the bottom inner side of the connecting seat 1. The spring 43 is fixedly connected between the fixing rod 42 and one end of the inner side of the sliding groove 41, and the spring 43 is in a compressed state. One end of the fixing rod 42 is fastened to the inner side of the fixing groove 44.

[0026] Furthermore, by cooperating with the fixing rod 42 and the spring 43, the connecting seat 1 can be quickly disassembled and assembled when the cutting process is stopped, thereby realizing the function of quickly changing the cutting blade 36 and improving the efficiency of dovetail cutter cutting.

[0027] Specifically, the mounting component 6 includes a slot 61, a water supply channel 62, and a water spray hole 63. The slot 61 is respectively opened on the connector 5, and the connector 5 is fixedly connected to the milling equipment through the slot 61. The water supply channel 62 is opened at the center of the inner side of the shaft 2, and the water spray hole 63 is symmetrically opened on the circumferential surface of the shaft 2, and the water spray hole 63 is inclinedly set on the top side of the cutting blade 36.

[0028] Furthermore, coolant can be delivered through the water tank 62 via the inside of the shaft 2, and sprayed onto the cutting tool 36 through the angled spray hole 63 during cutting, thereby preventing the tool from overheating and extending its service life.

[0029] In use, the shaft 2 is slidably inserted into the bottom inner side of the connecting seat 1. At this time, the spring 43 pushes the fixing rod 42 to extend through its own elastic force, so that it is fastened into the inner side of the fixing groove 44, thus fixing the connecting seat 1 and the shaft 2. During cutting, the shaft 2 drives the connecting seat 1 to rotate, and under the action of centrifugal force, it drives the fixing rod 42 to extend, and stretches the spring 43. At this time, the fixing rod 42 is fastened into one end of the inner side of the fixing groove 44 to prevent the fixing from loosening and causing the cutting tool to fall off. After the machining stops, the spring 43 pulls the fixing rod 42 to return to its original position. When disassembling and replacing, pull the shaft 2. At this time, the edge of one end of the fixing groove 44 pushes the inclined surface of the fixing rod 42, causing it to retract to the inside of the slide groove 41, thereby contacting the fixing of the connecting seat 1 and the shaft 2, allowing for quick disassembly and replacement. During the machining process, the dovetail cutter is installed to the output end of the milling equipment through the connecting head 5. During the milling process, coolant is supplied to the water supply tank 62 inside the shaft 2, which is then sprayed from the inclined water spray hole 63 to the machining position of the cutting blade 36, thereby cooling it, preventing overheating, and extending the service life of the blade.

[0030] In summary, through the structure of the fixing component 4 and the mounting component 6, and through the cooperation of the spring 43 and the fixing rod 42, the function of quickly disassembling and replacing the cutting blade can be realized without affecting the cutting process. With the cooperation of the water supply tank 62 and the water spray hole 63, the cutting blade can be cooled down and its service life can be extended.

[0031] It should be understood that numerous specific implementation decisions can be made during the development of any actual implementation method, and in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0032] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
