[0019] Reference Figure 1-3 The image shown is a preferred embodiment of the present invention.

[0020] A cutter for cutting sheet-like objects includes a hand-held movable device 100, a pressure plate 200 connected to the movable device 100, the pressure plate 200 being located below the movable device 100 and having a cutting interval between it and the movable device 100 for the sheet-like object to pass through; the cutting interval is provided with longitudinally arranged cutting blades 300, which are connected to the pressure plate 200; during the movement of the movable device 100, the cutting blades 300 cut the sheet-like object entering the cutting interval; The aforementioned sheet-shaped cutter, by setting a pressure plate 200 below the mover 100, can ensure the sheet-shaped body is flat during the cutting process, and also avoids the situation where the sheet-shaped body cutter shifts, resulting in uneven cutting or wrinkling of the sheet-shaped body, thus improving the cutting effect and cutting quality of the sheet-shaped body; at the same time, the cutting interval forms a narrow controlled channel to flatten the sheet-shaped body before cutting, precisely limiting the cutting action to the target line, and preventing the sheet-shaped body from wrinkling and shifting.

[0021] In this embodiment, the mobile device 100 is equipped with a reflector 400 that emits a visual guide light forward. The reflector 400 is a lighting device that uses the principle of light reflection to achieve directional control of the light source. Through a special structural design, the light is concentrated and projected onto a specific area. The reflective lamp 400, which uses the principle of reflection to project light in a directional manner, emits highly concentrated visual guide light forward, forming a clear light path trajectory on the surface of the sheet-like object. This allows the operator to intuitively and accurately predict and calibrate the cutting path, overcoming the problem of losing the cutting direction due to viewing angle deviation or sheet-like object obstruction. It improves the trajectory accuracy and operational controllability of cutting long straight lines or complex shapes.

[0022] In this embodiment, the reflector 400 is an infrared lamp. The reflector 400 has an emitting position for emitting guiding light, which is aligned front-to-back with the cutting blade 300. Using an infrared lamp can increase visual color difference and better identify the position of the trajectory. At the same time, the emitting position is aligned front-to-back with the cutting blade 300 to ensure that the trajectory formed by the infrared lamp coincides precisely with the actual cutting path, avoiding interference from visible light on the operator's vision.

[0023] In this embodiment, the mover 100 is provided with auxiliary rollers, and the pressure plate 200 is arranged in front of the rollers along the moving direction of the mover 100 during cutting; auxiliary rollers are provided at the bottom of the mover 100, and the rolling direction of the rollers is specified to be consistent with the cutting moving direction. Meanwhile, the pressure plate 200 is fixedly installed in front of the roller, so that when moving and pushing, the pressure plate 200 can flatten the sheet before the roller contacts the sheet, and then the roller provides stable moving support, thereby improving the smoothness of pushing the mover 100 and the cutting stability while ensuring the flattening effect.

[0024] In this embodiment, the mover 100 is provided with a hollow area for fingers to pass through, and a hand handle 500 for gripping is provided on the hollow area; the hollow area for fingers to pass through and the integrated hand handle 500 are provided so that the operator's hand can be naturally embedded in the mover 100 for gripping, which is convenient for manual operation; it also ensures the stability of the grip and the uniformity of the force applied, which can prevent the hand from slipping or the cutter from tilting when pushing and cutting, and can also reduce operator fatigue.

[0025] In this embodiment, the front end of the pressure plate 200 extends with two pressure plates 201, which are arranged at intervals to form an open central gap. The two spaced-apart pressure plates 201 form a central open structure, allowing the operator to directly observe the cutting path and current cutting position of the sheet through the central gap, thus realizing visual monitoring of the cutting process. At the same time, the double pressure plate 201 structure can provide sufficient flattening force on both sides of the cutting line to prevent the sheet from wrinkling, thereby improving cutting accuracy and ease of operation.

[0026] In this embodiment, the middle part of the pressing plate 200 is provided with a protruding ridge 202. The protruding ridge 202 extends along the moving direction of the mover 100. The lower part of the cutting blade 300 is connected to the protruding ridge 202, and the upper part of the cutting blade 300 is exposed on the protruding ridge 202. A raised ridge 202 extending along the moving direction is provided in the middle of the pressure plate 200, and the lower part of the cutting blade 300 is fixed on the raised ridge 202. This not only enhances the rigidity of the local structure of the pressure plate 200 and can resist the longitudinal torsional stress generated during cutting, but also provides a stable mounting base and force support for the cutting blade 300 through the three-dimensional structure of the raised ridge 202. At the same time, it ensures that the upper part of the cutting blade 300 is fully exposed to achieve a precise cutting depth, and ultimately maintains the straightness and stability of the cutting trajectory even under complex stress conditions.

[0027] In this embodiment, the front end of the protruding ridge 202 is provided with a guide end face 203. Along the moving direction of the mover 100 during cutting, the guide end face 203 is arranged to be inclined backward. The guide end face 203 at the front end of the protruding ridge 202 is inclined backward, so that the cutter can make contact with and guide the sheet body with a smooth inclined surface when moving and cutting, ensuring the gradual flattening transition of the sheet body and reducing the moving resistance. The inclined guide surface diverts the contact stress of the sheet body, avoiding the sheet body from curling, jamming or wrinkling at the moment of cutting.

[0028] In this embodiment, the cutting interval is provided with two longitudinally arranged longitudinal walls 204, which extend in the same direction as the protruding ridge 202; the top of the longitudinal wall 204 is connected to the mover 100, and the bottom of the longitudinal wall 204 has a bottom limiting interval with the pressure plate 200; the two longitudinal walls 204 are arranged at intervals to form a transverse limiting interval, and the cutting blade 300 is located in the transverse limiting interval; The two longitudinal walls 204, together with the bottom limiting interval and the lateral limiting interval, form a constrained channel within the cutting interval. The bottom limiting interval not only precisely controls the entry thickness of the sheet, but also strictly constrains the displacement of the sheet in the width direction using the lateral limiting interval. This ensures that the sheet remains flat during the cutting process, preventing lateral jitter and longitudinal undulations. At the same time, it provides all-round operation protection and precise guidance for the cutting blade 300, ultimately achieving ultra-high precision and stable cutting.

[0029] In this embodiment, the pressure plate 200 is provided with a socket that is detachably connected to the mover 100. The bottom of the mover 100 is provided with an upwardly recessed slot 600, and the socket is inserted into the slot 600. A positioning shaft 700 is protruding from the socket, and a positioning groove extends upward from the top of the slot 600, and the positioning shaft 700 is inserted into the positioning groove. The plug-in connection between the socket and slot 600 and the precise engagement between the positioning shaft 700 and the positioning groove enable a fast, stable, and precise modular connection between the pressure plate 200 and the mover 100. This not only ensures that the pressure plate 200 can automatically maintain a precise relative position with the cutting blade 300 without adjustment during installation, avoiding the problem of cutting accuracy being affected by assembly errors, but also makes the disassembly and replacement of the pressure plate 200 simple and efficient, greatly improving maintenance convenience and operational efficiency.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
