[0020] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0021] In the description of the embodiments of the present invention, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the product of the utility model is usually placed when in use. It is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, it should not be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0022] Furthermore, the use of terms such as "horizontal," "vertical," and "overhanging" does not necessarily imply that the component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0023] In the description of the embodiments of the present invention, “a plurality of” means at least 2.

[0024] In the description of the embodiments of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0025] In conjunction with the accompanying drawings, a convenient cutter replacement device includes a fixing module 1, on which a first fixing component and a second fixing component are provided;

[0026] The first fixed component includes four movable modules 2, and the four movable modules 2 form a rectangle;

[0027] The second fixing assembly includes four modules 3, and the four modules 3 form a rectangle;

[0028] A central expander 4 is provided between the first fixing assembly and the second fixing assembly, and the central expander 4 is located at the center of the first fixing assembly and the second fixing assembly;

[0029] A card slot 5 is provided at the edge of the first fixing component, and a side expander 6 is provided at the edge of the second fixing component. The side expander 6 is opposite to the card slot 5 and is used in conjunction with the card slot 5.

[0030] Trapezoidal limiting grooves 7 are also provided on the sides of the first fixing component and the second fixing component to control the two to move only in a straight line;

[0031] A template expander 8 is provided on the top and bottom of the fixed module 1 to limit the periphery of the movable template 2 and the template 3 and to plug the holes generated during the splicing.

[0032] The central expander 4 is used to clamp the cutter blade.

[0033] The side expanders 6 are used to control the opening and closing of the central expander 4 .

[0034] The side expander 6 is engaged with the card slot 5 through a locking mechanism to ensure the stability of the device.

[0035] The first fixing component and the second fixing component are made of high-strength engineering plastic or metal material to ensure the durability and stability of the device.

[0036] The fixing module 1 is provided with bevel edges 9 on both the left and right sides, and the whole structure is locked by squeezing and moving.

[0037] During implementation, when the cutter blade needs to be replaced, the side expanders are operated to disengage them from the retaining slots. The first fixing assembly is then moved to release the central expander from the cutter blade. Next, the new cutter blade is placed within the clamping range of the central expander. The side expanders are again operated to engage the retaining slots, whereupon the central expander secures the new cutter blade, completing the cutter blade replacement. Throughout this process, the trapezoidal retaining grooves restrict the first and second fixing assemblies to linear motion, ensuring operational stability and accuracy.

[0038] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without creatively designing a structure and embodiment similar to the technical solution, they shall fall within the scope of protection of the present invention.
