[0027] 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.

[0028] Reference Figure 1 , Figure 3 , Figure 4 This utility model provides an embodiment of a high-life superhard cutting tool, including a blade mounting structure 1, a blade fixing structure 4 rotatably connected to the top of the blade mounting structure 1, a support plate structure 3 inside the blade mounting structure 1, a cutting blade 2 connected above the support plate structure 3, the blade mounting structure 1 including a mounting structure body 101, a lifting space 110 fixedly provided inside the mounting structure body 101, sliding grooves 105 fixedly provided on both sides of the lifting space 110, sliders 106 slidably connected to the two sliding grooves 105, a sliding sleeve 104 fixedly connected between the two sliders 106, a second threaded rod 107 threadedly connected inside the sliding sleeve 104, a second handle 108 fixedly connected to the bottom of the second threaded rod 107, and a support plate structure 3 including a support plate body 305, the support plate body 305 being fixedly connected to the sliding sleeve 104.

[0029] Specifically, turning the second handle 108 causes the second threaded rod 107 to rotate, which in turn causes the sliding sleeve 104 to rise. Under the limiting action of the sliding groove 105, the sliding sleeve 104 causes the pallet body 305 to rise vertically.

[0030] Reference Figure 4 A rotating plate 301 is rotatably connected above the main body 305 of the pallet. Three No. 1 screw mounting holes 302 are fixedly provided on the rotating plate 301. A No. 2 screw mounting hole 303 is fixedly provided in the middle of the rotating plate 301. A No. 1 threaded rod insertion hole 304 is fixedly provided on one side of the main body 305 of the pallet. A No. 1 threaded rod 102 is threadedly connected to one side of the main body 101 of the mounting structure. A No. 1 handle 103 is fixedly provided at one end of the No. 1 threaded rod 102.

[0031] Specifically, there is a rotating shaft below the rotating plate 301, which can rotate horizontally above the pallet body 305. Turning the first handle 103 causes the first threaded rod 102 to rotate into the first threaded rod insertion hole 304, thereby fixing the pallet body 305 in the current position, preventing it from rising or falling.

[0032] Reference Figure 2 , Figure 3The main body 101 of the mounting structure is fixedly provided with a blade placement groove 109. The cutting blade 2 is located inside the blade placement groove 109. The cutting blade 2 includes a blade body 201. Three No. 1 screw insertion holes 202 are fixedly provided at the three corners of the blade body 201. A No. 2 screw middle insertion hole 203 is fixedly provided on the blade body 201. A No. 1 screw 204 is threadedly connected to the three No. 1 screw insertion holes 202. The three No. 1 screws 204 are threadedly connected to the No. 1 screw mounting holes 302.

[0033] Specifically, the internal space of the blade placement slot 109 is completely identical to the shape of the cutting blade 2. During normal use, the cutting blade 2 is confined within the blade placement slot 109 and cannot move. After the No. 1 screw 204 is inserted into the No. 1 screw insertion hole 202, it stops at the No. 1 screw mounting hole 302, firmly fixing the blade body 201 and the rotating plate 301 together. The blade body 201 is made of PCD material, which is polycrystalline diamond produced using modern high-pressure technology. This is an ultra-hard composite material formed by sintering artificial diamond particles through a high-temperature and high-pressure process. It has high hardness, high compressive strength, good thermal conductivity, and good wear resistance, resulting in high machining accuracy and efficiency.

[0034] Reference Figure 5 The blade fixing structure 4 includes a rotating arm 401. The rotating arm 401 is fixedly provided with a second screw upper insertion hole 404 on one side of the mounting structure body 101. A second screw 402 is threadedly connected to the second screw upper insertion hole 404. The second screw 402 is threadedly connected to the second screw middle insertion hole 203. The second screw 402 is threadedly connected to the second screw mounting hole 303.

[0035] Specifically, screw 402 is inserted into the upper insertion hole 404 of screw 402, passes through the middle insertion hole 203 of screw 402, and finally stops at the mounting hole 303 of screw 402, thus firmly fixing the rotating arm 401, the blade body 201 and the rotating plate 301 together.

[0036] Reference Figure 5 , Figure 6 A No. 3 screw mounting hole 403 is fixedly provided on the side of the rotating arm 401 away from the mounting structure body 101. A No. 3 screw 406 is threaded onto the No. 3 screw mounting hole 403. A rotating ring 405 is fixedly provided at the bottom of the side of the rotating arm 401 away from the mounting structure body 101. The rotating ring 405 is slidably connected to the mounting structure body 101.

[0037] Specifically, the main body 101 of the mounting structure has a rotating groove inside, and the rotating ring 405 can rotate horizontally inside it. When the No. 3 screw 406 is threaded into the No. 3 screw mounting hole 403, it will fix the rotating arm 401 and prevent it from rotating.

[0038] Working principle: When one side of the blade wears down during use, tighten screws 402 (number two) and 406 (number three) to rotate the rotating arm 401 away from the blade body 201. Then, tighten handle 103 to rotate threaded rod 102 away from threaded rod insertion hole 304, releasing the support plate body 305 from fixation. Tighten handle 108 to rotate threaded rod 107, causing sliding sleeve 104 to rise. Under the limiting action of sliding groove 105, sliding sleeve 104 drives support plate body 305 to rise vertically until the blade body 201 leaves the blade placement slot 109. Then, push the blade body 201, which will rotate under the action of rotating plate 301, rotating it to a suitable position and switching to the other angle. Then, tighten handle 108 again to slowly lower it into blade placement slot 109, after which it cannot rotate freely horizontally. Turn the first handle 103 to rotate the first threaded rod 102 into the first threaded rod insertion hole 304, thus fixing the pallet body 305 in its current position so that it will not rise or fall. Then rotate the rotating arm 401 to directly above the blade body 201 and insert the second screw 402 and the third screw 406 back into their original positions to complete the replacement of the blade angle.

[0039] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
