DETAILED DESCRIPTION

[0031] The concept and technical effects of the present invention will be clearly and completely described below in conjunction with embodiments to fully understand the purpose, features and effects of the present invention.

[0032] This application has designed an integrated design cutting tool, such as the attached Figure 1-2 As shown, it includes a casing 1, a casing 2, a fixed blade 4, an integrated blade set 5, a connecting rod 23, an adjustment component, and a storage component;

[0033] The second shell 2 is connected to the first shell 1 by a connecting rod 23, the right end of the connecting rod 23 is connected to the inner wall of the second shell 2 by bolts, the fixed blade 4 and the integrated knife group 5 are both located between the first shell 1 and the second shell 2, and the outer sides of the first shell 1 and the second shell 2 are both provided with flanges connected to the cutting equipment, which are used to drive the knife to rotate, so as to cut the product;

[0034] The integrated blade set 5 is arranged on the right side of the fixed blade 4, and the fixed blade 4 is connected to the casing 1 by bolts;

[0035] The adjusting component is connected to the second casing 2, the storing component is arranged inside the second casing 2, and the storing component is connected to the adjusting component.

[0036] The outside of the housing 1 is fixedly connected with a limit ring 3, the right side of the limit ring 3 is in close contact with the fixed blade 4, the outer ring diameter of the limit ring 3 is smaller than the outer ring diameter of the fixed blade 4, and the cutting depth is limited by the limit ring 3 to prevent the tool from cutting too deep and causing damage to the workbench where the product is placed.

[0037] As attached Figure 3 As shown, the integrated blade set 5 includes an arc-shaped blade 1 51 and an arc-shaped blade 2 52;

[0038] The size and curvature of the arc blade 1 51 and the arc blade 2 52 are the same. Multiple groups of arc blades 1 51 and arc blades 2 52 form a complete circle, and the radius of the circle is the same as that of the fixed blade 4 .

[0039] The adjustment assembly includes a fixing hole 21, a rotating rod 22, a gear ring 221, and a gear 222;

[0040] The rotating rod 22 is located inside the second casing 2. A through rotating groove is formed on the outer wall of the second casing 2. The outer end of the rotating rod 22 passes through the rotating groove to the outside of the second casing 2. The rotating rod 22 is movably connected to the rotating groove.

[0041] There are two fixing holes 21, both of which are opened on the outer wall of the casing 2, and are respectively located at the two ends of the rotation groove. The outer end of the rotating rod 22 is connected to the fixing hole 21 by a bolt to prevent the rotating rod 22 from rotating autonomously.

[0042] The gear ring 221 is rotatably connected to the center of the housing 2, and the gear ring 221 coincides with the axis of the fixed blade 4, and the gear ring 221 is fixedly connected to the inner end of the rotating rod 22;

[0043] The number of the gears 222 is the same as that of the second arc-shaped blades 52 . The gears 222 are rotatably connected inside the second sleeve shell 2 , and the gears 222 are meshedly connected with the gear ring 221 .

[0044] As attached Figure 4 As shown, the storage assembly includes a connecting piece 53, a movable plate 531, a limiting slide rod 532, a fixed plate 533, a movable rod 534, and a telescopic rod 535;

[0045] The connecting piece 53 is connected to the inner side of the arc-shaped blade 2 52 by screws, and the inner side of the arc-shaped blade 1 51 is provided with a structure identical to the connecting piece 53, and the connecting piece 53 is rotatably connected to the connecting piece 53 by a hinge;

[0046] A 180° arc groove is formed on the top of the movable plate 531, and a pin is fixedly connected to the inner side of the connecting plate 53, and the pin is movably connected to the arc groove;

[0047] A notch is provided on the side of the movable plate 531, and the limiting slide bar 532 is movably connected to the notch, and the limiting slide bar 532 is fixedly connected to the fixed blade 4;

[0048] The fixed plate 533 is located on the right side of the movable plate 531, and the fixed plate 533 is fixedly connected to the fixed blade 4. The outer wall of the fixed plate 533 is provided with a through folding groove;

[0049] The movable rod 534 is fixedly connected to the pin, and the right end of the movable rod 534 passes through the folding groove and is movably connected therebetween;

[0050] The bottom end of the telescopic rod 535 is fixedly connected to the gear 222, and the right end of the movable rod 534 passes through the telescopic end of the telescopic rod 535 and is movably connected therebetween. The telescopic rod 535 is a radial telescopic sleeve rod with a structure similar to an umbrella handle in the prior art.

[0051] Working principle: the staff removes the bolt on the rotating rod 22, and then rotates the rotating rod 22. The rotating rod 22 drives the gear ring 221 to rotate, the gear ring 221 drives the gear 222 to rotate, the gear 222 drives the telescopic rod 535 to rotate, the telescopic rod 535 drives the movable rod 534 to move laterally along the folding groove, the movable rod 534 drives the pin to rotate along the arc groove, the pin drives the connecting piece 53 and the arc blade 2 52 to rotate until the arc blade 2 52 fits with the arc blade 1 51, and then the movable rod 534 moves to the longitudinal part of the folding groove and continues to move, the movable rod 534 drives the pin and the movable plate 531 to move longitudinally, the pin drives the arc blade 2 52 and the arc blade 1 51 to be retracted into the interior of the sleeve 2, and then the rotating rod 22 is fixed by bolts, thereby reducing the overall thickness of the tool, so that the current cutting width is the thickness of the fixed blade 4. When the cutting width needs to be widened, the integrated knife group 5 is opened by the opposite operation. The cutting width before is the total thickness of the fixed blade 4 and the curved blade. At this time, the rotating rod 22 is fixed to the sleeve shell 2 by bolts, the tooth ring 221 and the gear 222 are also in a stationary state, the rotation angle of the telescopic rod 535 is fixed at this time, and the curved blade 1 51 and the curved blade 2 52 are fully unfolded into a connected arc. When an external force is applied, the curved blade 1 51 and the curved blade 2 52 cannot move toward the center, so that the movable plate 531 remains in a fixed state, so that the integrated knife group 5 and the fixed blade 4 are in a relatively fixed state, and the movable plate 531 cannot rotate relative to the fixed blade 4 under the limiting action of the limiting slide bar 532. Therefore, the problem of unstable cutting caused by the integrated knife group 5 rotating or shrinking relative to the fixed blade 4 during the cutting process can be avoided, so that the cutting width can be flexibly adjusted according to the use requirements, and there is no need to frequently replace the tool, thereby improving the cutting efficiency and avoiding installation errors causing the product cutting size to exceed the standard.

[0052] The above embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work shall all fall within the scope of protection of the present invention.
