[0002] With the continuous development of the photography and film industries, the requirements for film cutting are also increasing. Different photography projects and film shooting scenes have more diverse requirements for film size and specifications, so an adjustable film cutting device is needed.

[0003] Existing patent document CN211415323U discloses a film cutting machine, which includes a frame, a mounting frame, and a cutting assembly. The frame is provided with a worktable for laying film. The mounting frame is mounted on the worktable and is provided with a guide rod arranged along the film cutting direction. The cutting assembly includes a mounting base and a blade. The blade is mounted on the mounting base and is used to cut the film. The mounting base is slidably connected to the guide rod and slides along the length direction of the guide rod. The film cutting machine of this utility model has a mounting base that slides on the guide rod. The mounting base moves smoothly and quickly under the guidance of the guide rod, resulting in good stability and high precision in blade cutting. This effectively avoids uneven edges, burrs, and other defects in the film. However, the CN211415323U technology does not allow for precise blade-film contact during operation. It is difficult to maintain a perfect fit with the film surface throughout the process. Furthermore, operators cannot visually see the current setting and the progress of the adjustment when adjusting the cutting size. Therefore, there is an urgent need for a film cutting device with adjustable size. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a film cutting device with adjustable size to solve the problems of existing film cutting devices, such as the inconvenience of precise blade-film contact during use, the difficulty in maintaining complete contact with the film surface during operation, and the inability of operators to intuitively see the current size setting and adjustment progress when adjusting the cutting size.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a size-adjustable film cutting device, comprising a base, with abutment blocks welded to the outer wall of the base, connecting frames welded to both sides of the base, a movable frame installed on the outer wall of the connecting frame, rubber sleeves fitted to the outer wall of the movable frame, a measuring ruler installed on the outer wall of the movable frame, a marking rod abutting the outer wall of the measuring ruler, a connecting sleeve welded to one end of the marking rod, and a cutting blade welded to the lower end of the connecting sleeve.

[0006] A spring is welded to the outer wall of the cutting blade, and a limiting sleeve is welded to one end of the spring. Both sides of the limiting sleeve are abutted by fixing sleeves.

[0007] Preferably, the connecting frame is movably connected to the movable frame, and the connecting frame and the movable frame are arranged perpendicularly.

[0008] Preferably, the outer wall of the movable frame is tightly fitted to the inner wall of the rubber sleeve, and the rubber sleeve is symmetrically arranged about the central axis of the movable frame.

[0009] Preferably, the movable frame is engaged with the scalar ruler, and the inner wall of the scalar ruler has an open design.

[0010] Preferably, the movable frame is engaged with the connecting sleeve, and the connecting sleeve is evenly spaced on the outer wall of the movable frame.

[0011] Preferably, the limiting sleeve is movably connected to the movable frame, and the limiting sleeve is evenly spaced on the outer wall of the movable frame.

[0012] Preferably, the fixed sleeve is threadedly connected to the movable frame, and the outer wall of the movable frame is threaded.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model uses a movable frame to lock and fix the scale. When using the device, the scale is set to make it easy for the marking rod to fit, making it easy to see the current setting size and the progress of adjustment, and making it easy to adjust the cutting size.

[0015] 2. This utility model uses a spring to connect the cutting blade. When using the device, the setting of the cutting blade and the spring facilitates the precision of the cutting blade's fit with the film. During operation, it always maintains a state of complete fit with the film surface, which is convenient for cutting. Attached Figure Description
