Description

Technical Field

[0001] This application relates to the field of cutting and trimming tools, and more particularly to a multifunctional cutting and trimming tool. Background Technology

[0002] Existing trimmers are made of stainless steel with a cutting structure similar to the blade of scissors. The sheet metal to be cut is placed at the blade edge, and the trimmer is pulled along the scribing line as needed to cut the sheet metal.

[0003] Regarding the aforementioned technologies, the applicant believes that the following problems exist: the trimmer is only suitable for trimming thin metal sheets, and cannot be used for cutting and trimming materials such as wood boards and adhesive strips. Utility Model Content

[0004] To be applicable to cutting and trimming various materials, this application provides a multi-functional cutting and trimming tool.

[0005] This application provides a multifunctional cutting and trimming tool, which adopts the following technical solution:

[0006] A multi-functional cutting and trimming tool includes a handle and a cutting mechanism connected to the handle. The cutting mechanism includes a cutting blade, an upper pressure wheel assembly, and a lower pressure wheel assembly.

[0007] The cutting blade includes a cutting edge;

[0008] The upper and lower clamping roller assemblies are located in the feeding direction of the cutting edge and are used to clamp the material to be cut.

[0009] By employing the above technical solution, the upper and lower clamping roller assemblies work together to clamp the material to be cut in the feeding direction of the cutting edge, ensuring that the cutting position of the material is directly aligned with the cutting edge, thus guaranteeing precise alignment and preventing deviation. Furthermore, because the thin edge of the material is directly opposite the cutting edge after clamping, even non-rigid materials will not deviate from the cutting edge position. Therefore, this method can be used not only to cut thin metal sheets but also to cut materials such as wood and adhesive strips.

[0010] Preferably, it also includes an adjusting component for adjusting the distance between the upper clamping wheel assembly and the lower clamping wheel assembly.

[0011] By adopting the above technical solution, the distance between the upper clamping roller assembly and the lower clamping roller assembly can be adjusted to accommodate materials of different thicknesses to be cut.

[0012] Preferably, the cutting blade / handle is provided with a mounting plate, one end of which is rotatably connected to the cutting blade / handle, and the other end of which is rotatably connected to the cutting blade / handle via an eccentric member. The center line of the relative rotation of the eccentric member and the mounting plate is parallel to the center line of the relative rotation of the eccentric member and the cutting blade / handle. The upper clamping wheel assembly / lower clamping wheel assembly is mounted on the mounting plate.

[0013] By adopting the above technical solution, since one end of the mounting plate is rotatably connected, the deflection angle of the mounting plate can be adjusted by the eccentric component at the other end, so that the distance between the upper clamping roller assembly / lower clamping roller assembly on the mounting plate and the other clamping roller assembly changes, in order to adapt to materials of different thicknesses to be cut.

[0014] Preferably, one end of the mounting plate is formed with a through hole, the eccentric member is cylindrical and located inside the through hole, and is connected to the cutting blade / handle by a bolt parallel to the axis of the eccentric member passing through the through hole, and the end of the eccentric member located outside the through hole is formed with a non-circular force-bearing column.

[0015] By employing the above technical solution, an eccentric component is installed using bolts. When this component, parallel to the bolt's axis, rotates, the position of the mounting plate changes relative to the bolt's axis. During adjustment, the mounting plate may experience a very small amount of deformation. A force-bearing column is used to conveniently apply force to adjust the eccentric component.

[0016] Preferably, the mounting plate is mounted on the cutting blade, and the cutting blade has a lower clearance hole with a size larger than that of the lower clamping wheel assembly, and the lower clamping wheel assembly is located inside the lower clearance hole.

[0017] By adopting the above technical solution, the lower clamping roller assembly is avoided by the lower clearance hole. At the same time, since the size of the lower clearance hole is larger than that of the lower clamping roller assembly, the lower clamping roller assembly will not interfere with the cutting blade when its position is adjusted.

[0018] Preferably, the handle includes a hand-held part and a mounting part. The hand-held part is tilted to one side from top to bottom, and the tilting direction is opposite to the feeding direction of the cutting edge. The upper left and right sides of the hand-held part are formed with protrusions.

[0019] By adopting the above technical solution, the handheld part is convenient for the operator to hold and use, and it is not easy to slip out of the hand. The tilting direction makes it convenient for the operator to apply force to cut materials.

[0020] Preferably, the mounting portion is connected to the lower end of the handheld portion and extends horizontally from the lower end of the handheld portion, with an arc transition between the upper side of the mounting portion and the side away from the handheld portion.

[0021] Preferably, the mounting part is formed with an upper groove, and an upper threaded sleeve is embedded at the bottom of the upper groove. The upper threaded sleeve passes through both sides of the mounting part. The upper clamping wheel assembly includes an upper mounting bolt that passes through the upper threaded sleeve from front to back and is threadedly connected to the upper threaded sleeve, and an upper roller connected to the bolt head of the upper mounting bolt. The lower surface of the upper roller is lower than the lower surface of the upper blade body. One end of the upper mounting bolt that is connected to and passes through the upper threaded sleeve is connected to an upper nut for locking and preventing loosening.

[0022] By adopting the above technical solution, the upper threaded sleeve is used in conjunction with the mounting bolt for installation. The upper lock nut locks and prevents loosening. The rotating roller can rotate with low resistance, making cutting easier.

[0023] Preferably, the cutting blade includes an upper blade body fixed to the lower end face of the mounting portion by bolts and a lower blade body connected to one end of the upper blade body. The upper blade body is plate-shaped and fits against the lower end face of the mounting portion. The lower blade body is plate-shaped and perpendicular to the upper blade body. The upper part of one end of the lower blade body is integrally formed and connected to the upper blade body. The upper surface of the lower blade body gradually slopes away from the upper blade body from one end to the other end. The cutting edge is formed by the staggered position of the upper blade body and the lower blade body.

[0024] By adopting the above technical solution, a cutting edge is formed by the vertical and staggered positions of the upper and lower blades, which is used to cut materials.

[0025] Preferably, a mounting plate is installed on the side of the lower cutter body, and a lower groove is formed on one side of the mounting plate. A lower threaded sleeve is embedded at the bottom of the lower groove. The lower threaded sleeve passes through both sides of the mounting plate. The lower clamping wheel assembly includes a lower mounting bolt that passes through the lower threaded sleeve from back to front and is threadedly connected to the lower threaded sleeve, and a lower roller connected to the bolt head of the lower mounting bolt. The position of the lower roller is staggered from that of the upper roller, and the upper surface of the lower roller is higher than the upper surface of the adjacent part of the lower cutter body. A lower nut is connected to one end of the lower mounting bolt that is connected to and passes through the lower threaded sleeve to lock and prevent loosening.

[0026] By adopting the above technical solution, the lower threaded sleeve is used in conjunction with the lower mounting bolt for installation. The lower lock nut locks in place to prevent loosening, and the lower roller connected to the rotatable connection can rotate with low resistance, making cutting easier.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The upper and lower clamping roller assemblies work together to clamp the material to be cut in the feed direction of the cutting edge, ensuring that the cutting position of the material is directly aligned with the cutting edge, guaranteeing precise alignment and preventing deviation. Furthermore, because the thin edge of the material is directly opposite the cutting edge after clamping, even non-rigid materials will not deviate from the cutting edge position. Therefore, it can be used not only to cut thin metal sheets but also to cut wood boards, adhesive strips, and other materials.

[0029] 2. Since one end of the mounting plate is rotatably connected, the deflection angle of the mounting plate can be adjusted by the eccentric component at the other end, so that the distance between the upper clamping roller assembly / lower clamping roller assembly on the mounting plate and the other clamping roller assembly changes, in order to accommodate materials of different thicknesses to be cut.

[0035] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0036] This application discloses a multifunctional cutting and trimming tool. The terms "up", "down", "left", "right", "front" and "back" used in the embodiments are schematic representations of relative directions and are not limitations on the positional relationship.

[0037] like Figure 1As shown, the multi-functional cutting and trimming tool includes a handle 1 and a cutting mechanism 2 connected to the lower end of the handle 1. The handle 1 includes a grip portion 3 and a mounting portion 4. The grip portion 3 tilts downwards and to the left with a gradually decreasing tilt angle. Both sides of the upper end of the grip portion 3 are formed with protrusions, which prevent the operator from easily slipping out of their hand when gripping the grip portion 3 and applying force. The mounting portion 4 is connected to the lower end of the grip portion 3 and extends to the right from the lower end of the grip portion 3. The upper and right sides of the mounting portion 4 have an arc transition.

[0038] like Figure 1 and Figure 2 As shown, the cutting mechanism 2 includes an upper clamping wheel assembly 5 connected to the mounting part 4, a cutting blade 6 mounted below the mounting part 4, a lower clamping wheel assembly 7 connected to the cutting blade 6, and an adjusting assembly 8 for adjusting the distance between the upper clamping wheel assembly 5 and the lower clamping wheel assembly 7. An upper groove 9 is formed in the center of the front of the mounting part 4, and an upper threaded sleeve 10 is embedded in the bottom of the upper groove 9. The upper threaded sleeve 10 passes through both sides of the mounting part 4. The upper clamping wheel assembly 5 includes an upper mounting bolt 11 that passes through the upper threaded sleeve 10 from front to back and is threadedly connected to it, and an upper roller 12 connected to the bolt head of the upper mounting bolt 11. An upper nut 14 is connected to one end of the upper mounting bolt 11 that extends out of the upper threaded sleeve 10 for locking and preventing loosening.

[0039] like Figure 2 and Figure 3 As shown, the cutting blade 6 includes an upper blade body 15 fixed to the lower end face of the mounting part 4 by bolts, and a lower blade body 16 connected to the right end of the upper blade body 15. The upper blade body 15 is a horizontal plate attached to the lower end face of the mounting part 4. An upper clearance hole 17 for the upper pressure roller assembly 5 is formed at the front of the middle of the upper blade body 15. The lower surface of the upper roller 12 is lower than the lower surface of the upper blade body 15. The lower blade body 16 is a vertical plate. The upper part of the right end of the lower blade body 16 is integrally formed and connected to the upper blade body 15. The upper end face of the lower blade body 16 is inclined downward from right to left, so that the upper surface of the left end of the lower blade body 16 is lower than the lower surface of the left end of the upper blade body 15. The upper blade body 15 and the lower blade body 16 are staggered to form a cutting edge 18.

[0040] like Figure 3 and Figure 4As shown, the adjustment assembly 8 includes a mounting plate 19 installed on the front side of the lower cutter body 16. The right end of the mounting plate 19 is connected to the lower cutter body 16 by bolts. The left end of the mounting plate 19 has a through hole 20, and an eccentric member 21 is provided in the through hole 20. The bolt passes through the eccentric member 21 and is connected to the lower cutter body 16. The eccentric member 21 is cylindrical, and the position where the bolt passes through the eccentric member 21 is not the axis of the eccentric member 21. The front end of the eccentric member 21 has an external hexagonal force-bearing column 22 for applying force to the eccentric member 21 (in other embodiments, the eccentric member 21 can also be integrally formed with the bolt to achieve a rotational connection between the eccentric member 21 and the lower cutter body 16). A lower clearance hole 23 is formed on the lower cutter body 16 at a position corresponding to the middle of the mounting plate 19. The size of the lower clearance hole 23 is larger than the size of the lower pressure wheel assembly 7.

[0041] like Figure 4 As shown, a lower groove 24 is formed on the rear side of the mounting plate 19, directly opposite the lower clearance hole 23. A lower threaded sleeve 25 is embedded at the bottom of the lower groove 24, and the lower threaded sleeve 25 passes through both sides of the mounting plate 19. The lower clamping roller assembly 7 includes a lower mounting bolt 26 that passes through the lower threaded sleeve 25 from back to front and is threadedly connected to the lower threaded sleeve 25, and a lower roller 27 connected to the bolt head of the lower mounting bolt 26. The position of the lower roller 27 is offset from that of the upper roller 12, and the upper surface of the lower roller 27 is higher than the upper surface of the adjacent part of the lower cutter body 16. A lower nut 28 is connected to one end of the lower mounting bolt 26 that is connected to and protrudes from the lower threaded sleeve 25 to lock and prevent loosening.

[0042] Specific usage process:

[0043] The eccentric component 21 rotates according to the thickness of the material to be cut. During the rotation of the eccentric component 21, the height of the axis changes slightly, and therefore the height of the left end of the mounting plate 19 also changes slightly. This causes the distance between the lower clamping wheel assembly 7 and the upper clamping wheel assembly 5 to change so that it matches the thickness of the material to be cut. Then, the trimmer is placed on the material to be cut. After the material to be cut enters the position between the upper clamping wheel assembly 5 and the lower clamping wheel assembly 7, the material to be cut is clamped. The operator continues to pull the trimmer so that the material to be cut enters the position of the cutting edge 18 and is cut.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
