One side of the second movable rod 13 penetrates the fixed blade 12 and is connected to the knife frame 11, so as to prevent the fixed blade 12 from shaking during cutting.

[0030] The round screw 17 is arranged through the middle of the knife frame 11 and its opposite sides extend out of the knife frame 11, and the round screw 17 and the handle 10 form a vertical relationship; the opposite sides of the knife frame 11 and the positions corresponding to the round screw 17 are installed with bearings 24 for the round screw 17 to pass through; the opposite sides of the round screw 17 outside the knife frame 11 are connected with knob nuts 19; the movable blade 18 is fixedly installed on the side of the movable knife frame 16 close to the fixed blade 12 by the second bolt 23; in this embodiment, the movable blade 18 is fixedly connected to the movable knife frame 16 by at least two second bolts 23. The round screw 17 passes through the movable blade 18 and the movable knife frame 16 and is threadedly connected to the movable knife frame 16; the part of the round screw 17 outside the knife frame 11 and on the opposite sides of the knob nut 19 are respectively installed with a first anti-loosening self-locking nut 30 and a second anti-loosening self-locking nut 21. The knob nut 19 is locked and positioned by the first anti-loosening self-locking nut 30 and the second anti-loosening self-locking nut 21 to prevent it from loosening. In actual operation, the movable tool holder 16 can be driven to move along the length direction of the round head screw 17 by manipulating the knob nuts 19 on both sides, thereby realizing the relative distance change between the movable blade 18 and the fixed blade 12. By setting the bearing 24, on the one hand, it can ensure that the round head screw 17 can rotate flexibly, and on the other hand, it can also ensure that the movable tool holder 16 will not swing, thereby ensuring the sampling accuracy.

The first movable rod 14 and the second movable rod 13 are both arranged to penetrate the movable blade 18 and the movable knife holder 16.

[0032] The first movable rod 14 and the second movable rod 13 are both fixedly connected to the knife frame 11 by the hexagon socket screws 25. When the first movable rod 14 and the second movable rod 13 need to be removed, only the hexagon socket screws 25 need to be removed and then the first movable rod 14 and the second movable rod 13 can be pulled out, which is easy to operate.

[0033] A first threaded hole 33 is provided on one side of the knife frame 11 corresponding to the handle 10, and one end of the handle 10 is threadedly connected to the knife frame 11. This structural arrangement facilitates assembly and disassembly of the knife frame 11 and the handle 10.

[0034] The inner wall of the blade frame 11 with the fixed blade 12 is provided with a first clearance groove 34 for receiving the second bolt 23; the movable blade 18 is provided with a through hole corresponding to the first bolt 22, and the movable blade holder 16 is provided with a second clearance groove 35 for receiving the first bolt 22 at a position corresponding to the through hole. Through such a structural setting, the fixed blade 12 and the movable blade 18 can be accurately returned to their positions, and the fixed blade 12 and the movable blade 18 can be in contact with each other. The minimum center distance between the fixed blade 12 and the movable blade 18 is set to 0.5mm.

[0035] In the present embodiment, the fixed blade and the movable blade are arranged on the same side without any obstruction between the two, so as to have a wider detection range. A first scale plate and a second scale plate are arranged. With the structure of the round-head screw, the scale value can be viewed at any time to fine-tune the relative distance between the fixed blade and the movable blade, thereby greatly improving the sampling accuracy and ensuring the detection quality. When adjusting the setting, it is only necessary to rotate the knob nuts on both sides to prompt the movable tool holder to drive the movable blade to move, thereby realizing the adjustment of the relative distance between the two blades, which is easy to operate.

[0036] In addition, in this embodiment, by providing the first movable rod 14 and the second movable rod 13, the movable tool holder 16 can move along the first movable rod 14 and the second movable rod 13, thereby playing a role in stable guiding and positioning, laying a further foundation for the accuracy of sampling.

[0037] The second embodiment, referring to Figure 3-5 As shown, on the basis of the first embodiment, a mounting hole 31 is provided on one side of the tool frame 11 and at a position corresponding to the first scale plate 15, a plug gauge fitting groove 36 is provided on an inner side wall of the tool frame 11 corresponding to the mounting hole 31, and a plug gauge 27 is fitted in the plug gauge fitting groove 36; a second threaded hole 32 connected to the mounting hole 31 is provided on the upper surface of the tool frame 11 and at a position corresponding to the mounting hole 31, a depth micrometer 28 is provided on one side of the tool frame 11, and one side of the depth micrometer 28 with a measuring rod 29 is correspondingly inserted into the mounting hole 31 and one end of the depth micrometer 28 is pressed and fixed by passing the hand screw 26 through the second threaded hole 32; the measuring rod 29 of the depth micrometer 28 corresponds to the position of the movable tool holder 16. When the depth micrometer 28 is not in use, the measuring rod 29 is tightened by the plug gauge 27 to prevent the measuring rod 29 from extending into the blade frame 11; when the depth micrometer 28 is in use, the plug gauge 27 is manually removed, and the measuring rod 29 will extend and contact the movable blade 18, thereby measuring the distance. In this embodiment, by providing the depth micrometer, the structure can achieve high-precision fine adjustment, and is easy to disassemble and assemble. It can be disassembled by loosening the hand screw 26, and the operation is simple and quick.

[0038] The above embodiments only express two implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent.
