Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] This application designs an adjustable cutting tool, as shown in the attached document. Figures 1-5 As shown, it includes a frame 1, an adjustment unit, a fixing unit, a disassembly unit, a blade holder 6, and a cutting blade 7;

[0038] The adjustment unit is installed on top of frame 1;

[0039] The fixing unit is located on the front of the adjusting unit;

[0040] The blade holder 6 is located below the fixed unit, and the cutting blade 7 is installed below the blade holder 6. Both the blade holder 6 and the cutting blade 7 are located above the frame 1.

[0041] The disassembly unit is located inside the tool holder 6.

[0042] Furthermore, the adjustment unit includes slide rail 1 2, control box 3, adjustment shaft 4, telescopic shaft 41, limit groove 42; slide rail 2 5;

[0043] The slide rail 12 is installed on the top of the frame 1, and the control box 3 is fixedly connected to the sliding part of the slide rail 12;

[0044] The adjusting shaft 4 is rotatably connected to the front of the control box 3, and the adjusting shaft 4 is a hollow structure.

[0045] The telescopic shaft 41 is movably connected to the lower part of the adjusting shaft 4, the limiting groove 42 is opened on the outer wall of the telescopic shaft 41, and the inner wall of the adjusting shaft 4 is provided with a slot that is movably connected to the limiting groove 42.

[0046] The slide rail 25 is installed on the front of the control box 3, and the sliding part of the slide rail 25 is rotatably connected to the telescopic shaft 41.

[0047] In the above embodiments, the adjusting shaft 4, slide rail 1 2 and slide rail 2 5 are all driven by the control box 3. A conveyor belt is installed on the top of the frame 1 for conveying leather. The telescopic shaft 41 and the adjusting shaft 4 are connected by a limiting groove 42, so that the telescopic shaft 41 and the adjusting shaft 4 maintain a relationship of joint rotation, which is used to adjust the direction of the knife holder 6.

[0048] Furthermore, the fixing unit includes a mounting strip 8, a locking block 9, a locking rod 10, a mounting groove 13, a connecting rod 11, and a limiting slide rod 12;

[0049] The mounting strip 8 is fixedly connected to the top of the cutting blade 7, and the mounting groove 13 is opened below the blade holder 6. The mounting strip 8 is movably connected to the mounting groove 13.

[0050] The locking block 9 is fixedly connected to the outer wall of the tool holder 6. There are two locking blocks 9 in each group. The two locking blocks 9 are located on both sides of the mounting slot 13 and are arranged in a staggered manner from high to low.

[0051] The locking rod 10 is located outside the mounting groove 13, and the width of the locking rod 10 is the same as the vertical distance between the two locking blocks 9;

[0052] The locking rod 10 is rotatably connected to the connecting rod 11 via a torsion spring. The limiting slide rod 12 is fixedly connected to the outer wall of the tool holder 6. The end of the connecting rod 11 away from the locking rod 10 is movably connected to the limiting slide rod 12.

[0053] In the above embodiments, when the lever 10 is in the lateral direction, it is locked between the two locking blocks 9. The lever 10 fixes the mounting strip 8 to prevent the cutting blade 7 from disengaging from the mounting groove 13. The elastic force applied by the torsion spring prevents the lever 10 from rotating on its own. The limiting slide rod 12 limits the lever 10 and the connecting rod 11, so that the lever 10 and the connecting rod 11 maintain radial sliding.

[0054] Furthermore, the disassembly unit includes a push plate 14 and a slider 15;

[0055] The push plate 14 is movably connected inside the mounting groove 13, and the cross-sectional dimensions and shapes of the push plate 14 and the mounting groove 13 are the same.

[0056] The slider 15 is fixedly connected to the push plate 14, and the end of the slider 15 away from the push plate 14 extends through to the outside of the tool holder 6 and is movably connected to the tool holder 6.

[0057] The slider 15 drives the push plate 14 to move outward, and the installation strip 8 can be pushed out of the installation slot 13 through the push plate 14, so as to facilitate the disassembly of the cutting blade 7.

[0058] Working principle: The operator inserts the installation strip 8 into the installation slot 13. The installation strip 8 pushes the push plate 14 to move into the installation slot 13. Then, the locking rod 10 is rotated to the vertical position and dragged downward. Then, the locking rod 10 is released. The torsion spring drives the locking rod 10 to rotate back to the horizontal position and lock between the two locking blocks 9 below, thereby fixing the cutting blade 7. The cutting blade 7 can be removed by reversing the operation. After the cutting blade 7 is installed, the leather to be cut is transported to the position of the cutting blade 7 by the conveyor belt. The rotating shaft 4 is adjusted to drive the telescopic shaft 41 and the blade holder 6 to rotate to the predetermined cutting angle through the limiting groove 42. Then, the telescopic shaft 41 and the blade holder 6 are lowered through the slide rail 2 5, so that the cutting blade 7 contacts the leather and cuts it, thereby completing the cutting work.

[0059] The above embodiments are only some embodiments of this utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the protection scope of this utility model.
