[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-5 The utility model provides a technical solution: a cemented carbide diamond coated milling cutter, comprising a handle 1, a moving block 2 is connected to the inside of the handle 1, a cutter head 3 is connected to the inside of the moving block 2, a moving mechanism is connected to one side of the cutter head 3, the moving mechanism is fixedly connected to the inner side of the handle 1, the moving mechanism is inside the moving block 2, a limiting mechanism is connected to one side of the moving block 2, a through hole 31 is opened inside the cutter head 3, and the limiting mechanism corresponds to the through hole 31; when the staff is ready to start using the milling cutter, the staff first presses the limiting mechanism, and the limiting mechanism no longer limits the small hole. The staff moves the moving block 2, and the moving mechanism will also move with the cutter head 3, so that the cutter head 3 can be extended and retracted. After the length adjustment is completed, the limiting mechanism is released, and the limiting mechanism is pressed into the through hole 31 again to complete the fixation. By setting the limiting mechanism and the moving mechanism, the staff only needs to operate the limiting mechanism and the moving block 2 to achieve rapid adjustment of the tool length, reducing the complexity of the operation. There is no need to frequently replace the cutter head 3, which reduces the labor cost caused by replacing the cutter head 3. The length of the tool is adjustable, so that it can adapt to more types of processing tasks, thereby enhancing its applicability and versatility.

[0026] The handle 1 and the moving block 2 are slidably connected, and the moving block 2 and the cutter head 3 are slidably connected; in this way, when the staff holds the moving block 2 and moves it, the cutter head 3 can also slide under the drive of the moving mechanism, thereby realizing the extension and retraction of the cutter, which is convenient for the staff to adjust the length of the cutter.

[0027] The moving mechanism includes a double rack 32, which is fixedly connected to the cutter head 3, and the double rack 32 is located inside the moving block 2. The upper and lower sides of the double rack 32 are meshed with gears 23. The upper and lower sides of the moving block 2 are provided with through slots 21, and the interior of the through slot 21 is fixedly connected with a cross bar 22. The gear 23 and the cross bar 22 are rotatably connected. The upper and lower inner sides of the handle 1 are fixedly connected with a single rack 11, and the single rack 11 is meshed with the gear 23. When the staff is ready to adjust the length of the tool, first the single rack 11 is fixed, and it mainly provides a meshing for the gear 23. When the staff pulls the moving block 2, the through slot 21 inside the moving block 2 1 The crossbar 22 inside will also move with it, and will move with the gear 23. The gear 23 is meshed with the single rack 11 and is rotatably connected with the crossbar 22. Therefore, the gear 23 will rotate while moving. The two rotating gears 23 are also meshed with the double rack 32. The rotation of the two gears 23 will move the double rack 32, so that the cutter head 3 fixedly connected thereto will move. Because the cutter head 3 and the moving block 2 are slidably connected, the moving block 2 has a certain supporting force for the cutter head 3. In this way, when the staff pulls the moving block 2, the cutter head 3 will also slide, inward or outward at the same time, to achieve the extension and retraction of the cutter. When the limit mechanism fixes the cutter head 3, the cutter head 3 cannot move, so the double rack 32 cannot move, so the gear 23 is stationary, the gear 23 is stuck with the single rack 11 at the top, the moving block 2 is also stationary, and the entire cutter is fixed. By providing a moving mechanism, the length of the device is easy to adjust, the staff can operate conveniently, the process of changing the length of the cutter is omitted, and the work efficiency is improved.

[0028] Long grooves are provided on the upper and lower inner sides of the handle 1, and the single rack 11 is fixedly connected inside the long grooves; the single rack 11 is fixed, the cutter head 3 and the moving block 2 are fitted, and the moving block 2 and the handle 1 are fitted.

[0029] The limiting mechanism includes a corresponding block 24, the corresponding block 24 is fixedly connected to the moving block 2, a short rod 25 is fixedly connected to the inside of the corresponding block 24, a rocker 26 is rotatably connected to the outside of the short rod 25, a spring 27 is fixedly connected to one side of the rocker 26, the spring 27 is fixedly connected to the moving block 2, and an insertion rod 28 is fixedly connected to the other side of the rocker 26, and the insertion rod 28 corresponds to the through hole 31; when the staff wants to adjust the length of the tool, the staff presses the end of the rocker 26 fixedly connected to the spring 27 to press the spring 27 downward. , so that the other end of the rocker 26, that is, one end of the plug rod 28, is lifted upward, so that the plug rod 28 leaves the through hole 31, and the restriction on the cutter head 3 is released. When the length adjustment is completed, the staff releases the rocker 26, and the compressed spring 27 rebounds and pushes upward, so that the plug rod 28 at the other end is re-inserted into the through hole 31 to fix the device. The middle of the rocker 26 is rotatably connected with the short rod 25, and the short rod 25 is fixed and is equivalent to a fulcrum, with one end of the fulcrum pointing upward and the other end pointing downward. By setting a limited position mechanism, the device can be fixed after the adjustment is completed, and the operation is simple and manpower is saved.

[0030] The short rod 25 is located in the middle of the rocker 26; the short rod 25 is equivalent to a fulcrum in the middle.

[0031] The inside of the cutter head 3 is hollow, and a metal mesh is fixedly connected to the inside of the cutter head 3; the hollow design can reduce the overall weight of the cutter head 3, making the tool more stable when rotating at high speed, reducing vibration and noise, and reducing the burden on the machine tool. The hollow inside is filled with a metal mesh, which can increase the rigidity of the cutter head 3 and improve its bending and torsion resistance.

[0032] The cutting part of the cutter head 3 is wavy; when rotating, it can produce a wave effect, thereby increasing the dynamic stability during cutting and reducing vibration and noise.
