[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 5 This utility model provides a technical solution: a freely detachable and adjustable easy-tear punch device, including a base 1, a frame 2 at the top of the base 1, a sliding component inside the frame 2, a connecting rod 7 at the top of the sliding component, a cylinder 8 fixedly embedded at the other end of the connecting rod 7, a bracket 9 at the output end of the cylinder 8, a fixing component inside the bracket 9, and a punch 18 on the fixing component. The fixing component allows for the fixing of the punch 18, making operation simple and convenient. Disassembly and assembly of the punch 18 does not require removing multiple bolts, thus solving the problem of easy tearing in existing technologies. The tear-off punch is inconvenient to disassemble and replace in actual use. Disassembly and replacement are complicated and time-consuming. By setting up a sliding component, the position of the punch 18 can be adjusted, which can be conveniently adjusted according to the actual use. This solves the problem that the existing easy-tear punch is not convenient to adjust the position of the punch 18 according to the different cutting positions of different packaging bags, and has poor flexibility in use. Activating the cylinder 8 causes the output end of the cylinder 8 to slide up and down, which in turn allows the punch 18 to slide up and down to cut the easy-tear opening of the packaging.

[0024] In this embodiment, the sliding assembly includes a screw 3, a knob 4, a slider 5, and a limiting assembly. One end of the screw 3 is rotatably connected to the rear side of the inner cavity of the frame 2 via a bearing, and the other end of the screw 3 extends to the front end of the frame 2 and is fixedly connected to the knob 4. The slider 5 is screwed to the outer wall of the screw 3 and is fixedly connected to the connecting rod 7. The limiting assembly is located at the bottom end of the inner cavity of the frame 2 and is fixedly connected to the bottom end of the slider 5. Rotating the knob 4 causes the knob 4 to drive the screw 3 to rotate. Under the action of the rotational force of the screw 3's outer wall thread, when the screw 3 rotates, the slider 5 can drive the connecting rod 7, the bracket 9, and the punch 18 to slide under the limiting action of the limiting groove 10 and the limiting block 11, thereby making it convenient to adjust the position of the punch 18 according to the position of the tear opening.

[0025] In this embodiment, the limiting component includes a limiting groove 10 and a limiting block 11. The limiting groove 10 is opened at the bottom of the inner cavity of the frame 2. The limiting block 11 is slidably embedded in the inner cavity of the limiting groove 10 and fixedly connected to the bottom of the slider 5. Under the combined action of the limiting groove 10 and the limiting block 11, the slider 5 can be prevented from rotating with the screw 3 when the screw 3 rotates.

[0026] In this embodiment, the inner cavity of the limiting groove 10 and the outer wall of the limiting block 11 are adapted to each other and are both in the shape of a "T". This allows one end of the limiting block 11 to always remain embedded in the inner cavity of the limiting groove 10, thereby improving the stability of the limiting component during use.

[0027] In this embodiment, the fixing component includes a fixing hole 19, fixing rods 20, sliding plates 15, and a moving component. The fixing hole 19 is opened through the punch 18. The two fixing rods 20 are detachably inserted into the inner cavity of the fixing hole 19 on both sides. The two sliding plates 15 are fixedly connected to the ends of the two fixing rods 20 that are far apart from each other. The moving component is disposed in the inner cavity of the bracket 9 and is fixedly connected to the two sliding plates 15. By moving the component, the two fixing rods 20 are inserted into the inner cavity of the fixing hole 19 on both sides, thereby fixing the punch 18. The operation is simple and convenient. When disassembling and assembling the punch 18, it is not necessary to remove and install multiple bolts. This solves the problem that the easy-tear punches of the prior art are inconvenient to disassemble and replace in actual use, and require complicated and time-consuming operations during disassembly and replacement. The outer wall of the fixing rod 20 fits well with the inner cavity of the fixing hole 19 and is square in shape.

[0028] In this embodiment, the moving assembly includes a lead screw 12, a turntable 13, moving blocks 14, and a connecting assembly. One end of the lead screw 12 is rotatably connected to the right side of the inner cavity of the bracket 9 via a bearing, and the other end of the lead screw 12 extends to the left end of the bracket 9 and is fixedly connected to the turntable 13. Two moving blocks 14 are respectively screwed to the left and right sides of the outer wall of the lead screw 12 and are respectively fixedly connected to the bottom ends of two sliding plates 15. The connecting assembly is located at the top of the inner cavity of the bracket 9 and is fixedly connected to the top of the two moving blocks 14. Rotating the turntable 13 causes the lead screw 12 to rotate, thereby causing the opposing threads on the left and right sides of the outer wall of the lead screw 12 to generate opposing threads. The rotational force of the thread causes the two moving blocks 14 to slide simultaneously toward the center of the lead screw 12 under the limiting action of the connecting groove 16 and the connecting block 17, respectively. This causes the two sliding plates 15 to drive the two fixed rods 20 to slide simultaneously toward the center of the inner cavity of the bracket 9, so that the two fixed rods 20 are inserted into the inner cavities of the fixing holes 19 on both sides, thereby fixing the punch 18. The operation is simple and convenient. When disassembling and assembling the punch 18, it is not necessary to remove and install multiple bolts. This solves the problem that the existing easy-tear punches are inconvenient to disassemble and replace in actual use, and require complicated and time-consuming operations during disassembly and replacement.

[0029] In this embodiment, the threads on the left and right sides of the outer wall of the lead screw 12 are arranged opposite to each other, so that when the lead screw 12 rotates, the left and right sides of its outer wall generate relative thread rotation force, so that the two sliders 5 slide relative to each other simultaneously under the limiting action of the limiting groove 10 and the limiting block 11.

[0030] In this embodiment, the connecting component includes a connecting groove 16 and a connecting block 17. The connecting groove 16 is opened at the top of the inner cavity of the bracket 9. Both connecting blocks 17 are slidably embedded in the inner cavity of the connecting groove 16 and are respectively fixedly connected to the top of the two moving blocks 14. Under the joint action of the connecting block 17 and the connecting groove 16, the moving block 14 can be prevented from rotating with the lead screw 12 when the lead screw 12 rotates.

[0031] In this embodiment, the inner cavity of the connecting groove 16 and the outer wall of the connecting block 17 are adapted to each other and are both dovetail-shaped.
