[0026] To further understand the content of the present invention, the invention will be described in detail with reference to the accompanying drawings.

[0027] Embodiment 1

[0028] The small film cutting device of this embodiment, as Figure 1 , 2 shown, includes a base 1, a slide bar 2, a buckle 3 and a slide rail. The slide rail is fixed on the edge surface of the base 1. Both ends of the slide bar 2 are slidably connected to the slide rail. The buckle 3 is connected to the slide bar 2. A blade 34 is connected to the bottom of the buckle 3. After the blade 34 passes through the slide bar 2, it abuts against the surface of the base 1.

[0029] In specific use, the film 7 to be cut is laid flat on the surface of the base 1. Through the positioning of the slide bar 2 and the guiding of the slide rail, the blade 34 at the bottom of the buckle 3 is guided to cut the film 7 laid on the surface of the base 1 in a fixed direction, thereby achieving the effect of efficiently cutting out the film 7 with uniform size and regular shape.

[0030] Embodiment 2

[0031] The small film cutting device of this embodiment has the same basic structure as that of Embodiment 1. The differences or improvements are as follows: As Figure 1 , 2As shown, it further includes a keycap 8, and the fixed end of the blade 34 is connected to the bottom surface of the keycap 8; the cross-section of the sliding rod 2 is a trapezoidal chute 21; the sliding buckle 3 includes a hollow sliding buckle body 31, and a cutting hole 32 for the blade 34 to pass through is opened at the bottom of the sliding buckle body 31; the keycap 8 is slidably buckled inside the sliding buckle body 31, and the telescopic movement of the blade 34 is realized through the keycap 8. While protecting the blade 34, the blade does not protrude after rebounding, preventing accidental cuts.

[0032] A first spring 35 is wound around the periphery of the blade 34, and the two ends of the first spring 35 respectively abut against the bottom surface of the keycap 8 and the edge of the cutting hole 32; limiting through holes 37 and limiting blind holes 81 are respectively opened on the side surfaces of the sliding buckle body 31 and the keycap 8 and are arranged in cooperation. A second spring 82 is horizontally fixed inside the limiting blind hole 81, and the outer end of the second spring 82 is connected to a limiting buckle 85; when the keycap 8 is pressed down inside the sliding buckle body 31 and the limiting through hole 37 coincides with the limiting blind hole 81, the second spring 82 pops the top end of the limiting buckle 85 out of the limiting through hole 37. Through the mutual cooperation of the first spring 35, the second spring 82 and the limiting through hole 37 and the limiting blind hole 81, the rebound type telescopic movement of the blade 34 is realized, which is convenient to operate and safe and reliable.

[0033] As Figure 2 , 3 shown, a groove 36 is provided on the bottom side surface of the sliding buckle body 31, and a side slide rail 26 matching the groove 36 extends inward from the inner side of the chute 21, which is convenient for the sliding buckle body 31 to be slidably adjusted on the sliding rod 2, and the adjustment operation is convenient.

[0034] A fixing hole 33 is also opened at the bottom of the sliding buckle body 31, and a rubber cap 83 matching the fixing hole 33 is provided on the bottom surface of the keycap 8. The sliding buckle 3 is fixed by the frictional force generated by the extrusion of the rubber cap 83 and the sliding rod 2, avoiding the displacement of the blade 34 during cutting.

[0035] The slide rails include longitudinal slide rails 5 and transverse slide rails 6 symmetrically distributed around the periphery of the base 1; the sliding rod 2 includes a longitudinal sliding rod and a transverse sliding rod; there are multiple sliding buckles 3, and multiple blades 34 perform simultaneous cutting on the film 7 in the longitudinal and transverse directions, multiplying the cutting efficiency.

[0036] Scale bars and auxiliary lines are drawn on the surface of the base 1, which is convenient for the blade 34 to perform precise cutting according to the guidance of the scale bars and the auxiliary lines.

[0037] It further includes a magnetic fixing device 4; the surface of the base 1 has magnetism; the magnetic fixing device 4 can press and adsorb the film 7 on the surface of the base 1, avoiding the wrinkling of the film 7 during cutting and improving the stability of the film 7 during cutting.

[0038] After the keycap 8 is pressed, the limit buckle 85 enters the limit through-hole 37 from the limit blind hole 81, the blade 34 is pressed down, and after being pressed down, the blade 34 abuts against the base 1. The snap 3 is fixed by the frictional force generated by the extrusion of the rubber cap 83 and the slide rod 2. After the snap 3 is fixed, the slide rod 2 can be moved to cut the film. By pressing the limit buckle 85, the keycap 8 pops up, and the blade 34 pops up synchronously.

[0039] In specific use, the film 7 is laid flat on the surface of the base 1, the film 7 is aligned by using the auxiliary lines on the base 1, and both sides of the film 7 are pressed tightly by the magnetic fixing device 4; according to requirements, the distance between the snaps 3 on the horizontal slide rod 2 is adjusted, the keycap 8 of the snap 3 is pressed, the snap 3 is fixed and the blade 34 is ejected, and the horizontal slide rod 2 is moved from the upper end to the lower end, and the film 7 is longitudinally cut; after use, the limit buckle 85 of the snap is pressed, and the blade 34 rebounds.

[0040] Embodiment 3

[0041] For the small film cutting device of this embodiment, the basic structure is the same as that of Embodiment 2. The differences or improvements are as follows: 2 slide rods 2, multiple snaps 3 and 2 slide rails are combined into a slide rail-slide rod-snap module. The slide rails are divided into a longitudinal slide rail 5 and a transverse slide rail 6. The height of the longitudinal slide rail 5 is lower than that of the transverse slide rail 6. Therefore, after the 2 slide rods 2 are combined with the longitudinal slide rail 5 and the transverse slide rail 6, the longitudinal slide rod 2 is higher than the transverse slide rod 2, and the two can move relatively vertically.

[0042] In specific use, the film 7 is placed flat on the base 1, the film 7 is aligned by using the auxiliary lines on the base 1, and both left and right sides of the film 7 are pressed tightly by the magnetic fixing device 4. According to requirements, the distance between the snaps 3 on the horizontal slide rod 2 is adjusted, the keycap 8 of the snap is pressed, the position of the snap 3 is fixed and the blade 34 is ejected, and the horizontal slide rod is moved from the upper end to the lower end, and the film 7 is longitudinally cut. Then the magnetic fixing device 4 is used to press both the upper and lower sides of the film 7 tightly. According to requirements, the distance between the snaps 3 on the longitudinal slide rod is adjusted, the keycap 8 of the snap is pressed, the position of the snap 3 is fixed and the blade 34 is ejected, and the longitudinal slide rod is moved from the left end to the right end, and the film 7 is transversely cut; after use, the limit buckle 85 of the snap is pressed, and the blade 34 rebounds.

[0043] The transverse slide rail 6 is higher than the longitudinal slide rail 7. After the slide rod 2 is combined with the slide rail, the transverse slide rod is below the longitudinal slide rod, avoiding mutual interference, and the two can move relatively vertically, realizing bidirectional multi-blade 34 parallel cutting.

[0044] When the limit buckle 85 is located in the limit through-hole 37, the limit buckle 83 is pressed inward, and the keycap 8 together with the blade 34 and the rubber cap 83 can be taken out. Then the keycap 8 is pressed into the snap main body 31, and the limit buckle 85 can re-enter the limit blind hole 81. Thus, the replacement of the blade 34 can be realized to ensure the film cutting efficiency.

[0045] The small film cutting device of this embodiment can meet the requirements of different specifications and quantities of the film 7 by adjusting the spacing between multiple scoring buttons 3 and combining the telescopic movement of the blades 34 on the scoring buttons 3; the two-way slide rails composed of horizontal and vertical directions can cut the film 7 in a grid pattern. The slide bar 2 moves longitudinally and horizontally along the slide rails, and the linearity of the film cutting process is good, and the shape is regular; multiple cutter heads 3 are combined to cut out multiple films at one time, with high efficiency; the blade 34 adopts a rebound telescopic design, which improves the safety of the cutting operation.

[0046] The above has schematically described the present invention and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure and manufacturing steps are not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments to this technical solution without creative work without departing from the purpose of the present invention, they shall fall within the protection scope of the present invention.
