Description

Technical Field

[0001] This utility model relates to a cutting device, and more particularly to a cutting device for preventing eardrum rupture. Background Technology

[0002] Currently, most eardrum cutting tools on the market are either single-blade straight-cutting or roller-type slit cutters. However, these eardrum cutting tools are easily affected by the material being cut; softer materials may curl at the edges, leading to edge breakage. Furthermore, existing cutting devices are bulky and difficult to install and operate. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model discloses a cutting device for preventing eardrum edge breakage, which solves the problem of edge breakage when cutting soft materials. It has a simple structure and is easy to install.

[0004] The technical solution of this utility model is as follows:

[0005] A cutting device for preventing eardrum rupture includes a cantilever fixing member, a blade holder, and a membrane material support plate. The lower end of the cantilever fixing member is rotatably connected to a fixing member. The fixing member is connected to the blade holder, and the blade holder is connected to a cutting tool. The membrane material support plate is located below the cutting tool and has a cutting edge corresponding to the position of the cutting tool. One side of the membrane material support plate is connected to the cantilever fixing member through a connecting bracket.

[0006] This technical solution allows for cutter angle adjustment by rotating the fixed component. The membrane support plate below the cutter provides upward force support for the membrane, effectively solving the edge curling problem of softer membrane materials. Furthermore, when the cantilever fixing component moves, the membrane support plate moves along with it, ensuring a fixed relative position between the cutter and the cutting edge on the membrane support plate. During adjustment, the earpiece is not affected by the cutting edge of the membrane support plate, thus preventing edge breakage. The entire device is simple in structure and easy to install.

[0007] As a further improvement of this utility model, the connecting bracket includes a first fixing member and a second fixing member. One end of the first fixing member is connected to the cantilever fixing member, and the other end is connected to the upper end of the second fixing member. The lower end of the second fixing member is connected to one side of the membrane material support plate. This technical solution simplifies the fixing structure of the membrane material support plate and does not interfere with the movement of the cutting tool.

[0008] As a further improvement of this utility model, the first fixing member is L-shaped.

[0009] As a further improvement of this utility model, the fixing member is provided with a limiting member, and the cantilever fixing member is provided with a first stop block. The first stop block is located above the fixing member, and the limiting member is located below the first stop block. The first stop block extends outward, serving to limit the rotation angle of the fixing member.

[0010] As a further improvement of this utility model, the cantilever fixing member is provided with a second stop, which is located on the rear side of the fixing member, and the limiting member is located between the first stop and the second stop. With this technical solution, the limiting member can rotate between the first stop and the second stop, thus limiting the rotation angle of the tool and improving reliability during use.

[0011] As a further improvement of this utility model, the fixing component is connected to the cantilever fixing component via a bearing. Furthermore, the bearing is made of stainless steel. Using this technical solution, the stainless steel bearing is the only component of the entire cutting device that is most easily damaged; it is low in cost and easy to replace.

[0012] As a further improvement of this utility model, the fixing component is cylindrical.

[0013] As a further improvement of this utility model, the cutting device for preventing eardrum rupture includes a horizontal adjustment mechanism. The cantilever fixing member is connected to the horizontal adjustment mechanism, and the horizontal position of the cantilever fixing member can be adjusted left and right through the horizontal adjustment mechanism. The horizontal adjustment mechanism allows for easy adjustment of the cutter's position at any time.

[0014] As a further improvement of this utility model, the horizontal adjustment mechanism includes a fixed frame, a lead screw, and a slider. The slider is connected to the lead screw, and the lead screw is rotatably connected to the fixed frame. The cantilever fixing member is fixedly connected to the slider.

[0015] As a further improvement of this utility model, the fixing frame is provided with a guide rail, and the slider is slidably connected to the guide rail.

[0016] The technical solution of this utility model can provide upward support for the membrane material, effectively solving the problem of edge curling in softer membrane materials. The cutter angle can be adjusted and limited, making it convenient to adjust and use. It can be used flexibly even in online mode and can be adjusted at will to meet the requirements of the desired position. In addition, the entire device is stable and lightweight, easy to install and disassemble, and has low maintenance costs. Attached Figure Description

[0025] The preferred embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] like Figures 1-4 As shown, a cutting device for preventing eardrum rupture includes a horizontal adjustment mechanism 1, a cantilever fixing member 2, a blade holder 4, and a membrane material support plate 6. The cantilever fixing member 2 is connected to the horizontal adjustment mechanism 1, which adjusts the horizontal position of the cantilever fixing member 2 left and right. The lower end of the cantilever fixing member 2 is rotatably connected to a fixing member 3. The fixing member 3 is connected to the blade holder 4, and the blade holder 4 is connected to a blade 5. The membrane material support plate 6 is located below the blade 5 and has a cutting edge 61 corresponding to the position of the blade 5. One side of the membrane material support plate 6 is connected to the cantilever fixing member 2 via a connecting bracket 7.

[0027] Specifically, the connecting bracket 7 includes a first fixing member 71 and a second fixing member 72. One end of the first fixing member 71 is connected to the cantilever fixing member 2, and the other end is connected to the upper end of the second fixing member 72. The lower end of the second fixing member 72 is connected to one side of the membrane material support plate 6. The first fixing member 71 is L-shaped.

[0028] The fixing member 3 is provided with a limiting member 31, and the cantilever fixing member 2 is provided with an outwardly extending first stop 21. The first stop 21 is located above the fixing member 3, and the limiting member 31 is located below the first stop 21. The first stop 21 serves to limit the rotation angle of the fixing member 3.

[0029] The fixing component 3 is connected to the cantilever fixing component 2 via a bearing. Furthermore, the bearing is made of stainless steel. The fixing component 3 is cylindrical.

[0030] The horizontal adjustment mechanism 1 includes a fixed frame 11, a lead screw 12, and a slider 13. The slider 13 is connected to the lead screw 12, and the lead screw 12 is rotatably connected to the fixed frame 11. The cantilever fixing member 2 is fixedly connected to the slider 13. The fixed frame 11 is provided with a guide rail, and the slider 13 is slidably connected to the guide rail.

[0031] Furthermore, the cantilever fixing member 2 is provided with a second stop, which is located on the rear side of the fixing member 3. The limiting member 31 is located between the first stop 21 and the second stop. The limiting member 31 can rotate between the first stop 21 and the second stop, which limits the rotation angle of the tool 5 and improves the reliability of use.

[0032] Using the technical solution of this embodiment, the membrane material 8 is placed on the membrane material support plate 6, and the cutter 5 is rotated. The cutter 5 cuts along the cutting edge 61 to cut off the eardrum 9. The horizontal adjustment mechanism 1 and the screw 12 can be rotated to freely move the cutter 5 left and right, allowing for flexible use even in online conditions. Furthermore, during left and right adjustments, the cutting edge 61 of the membrane material support plate 6 and the cutter 5 move simultaneously, ensuring that the eardrum 9 is not affected by the cutting edge gap of the membrane material support plate 6, thus avoiding edge breakage. The angle of the cutter 5 can be adjusted and limited through the cooperation of the limiting member 31, the first stop 21, and the cutter holder 4. The entire device has a simple structure and is easy to install and disassemble.
