[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Example 1

[0029] Reference Figures 1 to 6 The present embodiment provides a portable fireproof material cutting device, including a gripping member 100, which is in a "U" shape as a whole. The gripping member 100 is composed of a handle 101 and a connecting frame 102. There are two groups of connecting frames 102, and the two groups of connecting frames 102 are respectively arranged at the two ends of the outer wall of the gripping member 100; a rolling mechanism 200, which is arranged inside the two groups of connecting frames 102, and the rolling mechanism 200 is composed of an active roller 201, a driven roller 202 and a cutting member 300.

[0030] There are two groups of active rollers 201. The two groups of active rollers 201 and the driven rollers 202 are both provided with connecting pins 202b at the axis centers of the outer walls. The outer walls of the two groups of connecting frames 102 are penetrated with rotation grooves 103. The connecting pins 202b at the two groups of active rollers 201 and the driven rollers 202 are rotatably connected inside different rotation grooves 103. The two groups of active rollers 201 are both rollingly matched with the driven rollers 202. When it is necessary to cut the fire-fighting materials, pressure is applied to the handle 101 to make the outer walls of the two groups of connecting frames 102 parallel. When the two groups of connecting frames 102 are parallel, the fire-proof materials are clamped by the active rollers 201 and the driven rollers 202. At this time, the handle 101 is moved to make the two groups of active rollers 201 and the driven rollers 202 roll, so that the cutting piece 300 cuts the fire-fighting materials.

[0031] The cutting piece 300 includes a roller 301, which is connected between two sets of active rollers 201. A knife groove 202a is opened in the middle of the outer wall of the driven roller 202. The fire-fighting materials are clamped by the two sets of active rollers 201 and the driven rollers 202, so that the fire-fighting materials around the roller 301 are fixed to a certain extent when rolling, thereby reducing the production of defective products.

[0032] A rolling plate 301 a is disposed outside the hob 301 . The hob 301 and the rolling plate 301 a are both circular in shape, and the central axes of the hob 301 and the rolling plate 301 a are perpendicular.

[0033] A slide groove 201a is provided at the axis center of the outer wall of the two sets of rollers 301, and the roller 301a is rotatably connected inside the slide groove 201a; under normal conditions, the axis center of the roller 301 and the axis centers of the two sets of active rollers 201 are in a collinear state, and the cut edge is straight at this time, but when the roller 301a rotates inside the slide groove 201a, the axis center of the roller 301 and the axis centers of the two sets of active rollers 201 are not in a collinear state, and the cut edge is wavy at this time.

[0034] A plurality of positioning holes 301a-1 are provided at both ends of the outer wall of the roller 301a, and a spring block 201b is provided inside the slide groove 201a. The spring block 201b is connected to the inner wall of the slide groove 201a through a spring, and the spring block 201b is clamped in the positioning hole 301a-1. The clamping of the spring block 201b in the positioning hole 301a-1 realizes the fixation of the roller 301 between the two groups of active rollers 201. By controlling the spring block 201b to be clamped in different positioning holes 301a-1, the deflection angle of the roller 301 and the active roller 201 is controlled, thereby controlling the size of the wave of the cutting edge after cutting.

[0035] The thickness of the connecting frame 102 is smaller than the outer diameter of the active roller 201 and the driven roller 202. When the outer walls of the two sets of active rollers 201 and the driven rollers 202 are in contact, the outer walls of the two sets of connecting frames 102 are parallel to each other and the distance between them does not exceed 5 mm. As the cutting device moves, when the fireproof cloth overlaps at the cutting path of the fire-fighting material, the two sets of connecting frames 102 block the overlapping fireproof cloth and allow it to gradually enter the rolling mechanism 200.

[0036] The grip 101 is made of spring steel.

[0037] Working principle: the fireproof cloth is leveled before use, and then the cutting path is determined. The handle 101 is held and pressure is applied, and the bend of the handle 101 is deformed, so that the two sets of active rollers 201 and the driven rollers 202 clamp the fireproof cloth. Then the handle 101 is moved, and the fireproof cloth rolls between the active roller 201 and the driven roller 202 through the movement of the handle 101. While rolling, the fireproof cloth is cut by the roller 301 of the cutting piece 300. When the cutting edge of the fireproof cloth is required to be wavy, the roller 301a is rotated so that the roller 301a and the inside of the slide groove 201a rotate, so that the axis of the roller 301 and the axis of the active roller 201 are not in a colinear state. At this time, the cutting edge of the fireproof cloth is wavy, and different spring blocks 201b are controlled to be clamped in the positioning hole 301a-1, so as to control the deflection angle of the roller 301a, and then control the size of the wave.
