Description

Technical Field

[0001] This utility model relates to the field of manual tool technology, specifically a cutting and marking tool. Background Technology

[0002] In the field of plastic tarpaulin processing, such as freight tarpaulin production, outdoor sunshade awning processing, and tent tarpaulin cutting, cutting and marking are two closely linked and frequently occurring basic processes. Workers typically need to first mark the cutting outline, dimensional baselines, or key positioning points on the surface of the plastic tarpaulin according to the design dimensions, splicing positions, or installation hole requirements. Then, they use cutting tools to cut along the marked lines to ensure that the cut plastic tarpaulin meets specifications and subsequent processing and assembly needs.

[0003] Currently, the industry commonly uses a standalone tool combination scheme to complete the above two processes, that is, using a marker for marking and scissors, utility knives, and paper cutters for cutting. This traditional tool combination has gradually revealed many unavoidable shortcomings in practical application: First, carrying and storing tools is inconvenient. Plastic tarpaulin processing often involves various scenarios such as assembly line operations in workshops and on-site cutting outdoors. Workers need to carry at least two separate tools at the same time. When working outdoors or moving between multiple workstations in the workshop, the increased number of tools increases the burden of carrying them, and it is easy for a tool to be missed or lost. When storing, separate storage space needs to be planned for different tools. In particular, plastic tarpaulin processing workshops are often accompanied by fabric scraps, dust, etc., and individual tools are easily contaminated with debris. They need to be cleaned extra before being retrieved and put away, which reduces the efficiency of work preparation.

[0004] Secondly, the efficiency of process coordination is low. In the alternating operation of marking and cutting, workers need to frequently switch between holding the marker and the cutting tool. After each marking is completed, the marker must be put down and the cutting tool must be picked up again. If remarking is needed after cutting, the process must be switched again. The repeated switching not only increases the number of operation steps, but also easily disrupts the work rhythm. Especially in the scenario of large-scale continuous processing, the accumulated time loss will significantly reduce the overall production efficiency.

[0005] Furthermore, operational precision is easily affected. Plastic tarpaulins have a certain degree of toughness and surface smoothness. During tool switching, the operator's hand posture and center of gravity need to be readjusted, which can easily cause the tarpaulin to shift. This makes subsequent cutting unable to accurately follow the previously marked lines, thus affecting product dimensional accuracy and increasing the scrap rate. At the same time, cutting plastic tarpaulins requires ensuring clean cuts to avoid cracking. However, traditional small utility knives and other cutting tools, when used alone, lack a stable grip support structure, making them prone to cutting trajectory deviations and rough cuts, affecting product quality.

Detailed Implementation

[0021] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Please see Figures 1-5 This application provides the following technical solutions: A cutting and marking tool includes a grip structure 1 located in the middle, and marking structures 2 and cutting structures 3 located at both ends of the grip structure 1. The grip structure 1 is a cylindrical, elongated structure similar to a pen barrel, with an outer diameter large enough for easy one-handed gripping. The outer wall of the grip structure 1 can be covered with an anti-slip structure, such as an anti-slip pad or anti-slip stripes. Connecting parts are provided at both ends of the grip structure 1 along its length, and the tool connects to the cutting structures 3 through the different connecting parts at both ends and the marking structures 2.

[0023] The marking structure 2 is located at one end of the grip structure 1 along its length. The marking structure 2 includes a pen tip 21 and a liquid supply component 22. The pen tip 21 can draw markings on the tarpaulin to be processed. The grip structure 1 has an internal cavity, and the liquid supply component 22 is located within this cavity. The liquid supply component 22 includes a liquid supply tube, which is a long, tubular body filled with marking ink. The liquid supply tube can communicate with the pen tip 21. The pen tip 21 and the liquid supply component 22 are internally connected, forming a liquid supply path. The pen tip 21 and the liquid supply component 22 can adopt existing technical solutions, such as marker pens, as long as they can draw markings on the tarpaulin to be processed.

[0024] The cutting structure 3 is located at the other end of the holding structure 1 along its length. The cutting structure 3 includes a cutting head 31 for cutting the tarpaulin. The cutting head 31 can also adopt various different structural forms, as long as it can facilitate the cutting of the tarpaulin. Considering that the overall shape is similar to a pen, it would be inconvenient to use a scissor-type cutting head 31. Therefore, the cutting head 31 in this solution adopts a blade-type structure to cut the tarpaulin in a cutting manner.

[0025] Corresponding to the labeling structure 2 and the cutting structure 3, a label cap 4 and a cutting cap 5 are respectively provided. The label cap 4 adopts a structure similar to a conventional pen cap, and a clamping structure 6 is fixedly installed on its outside. The clamping structure 6 allows the label cap 4 to be attached to a pocket on the staff's clothing. The clamping structure 6 is a long strip plate as a clamp. One end of the clamp is fixedly connected to the outer wall of the label cap 4, and the other end has a protrusion on the side facing the label cap 4. The clamp can be made of plastic or metal.

[0026] like Figure 1 and Figure 2 As shown, the cutter cap 5 is roughly bullet-shaped, with one end plugging into the grip structure 1 and the other end being a folded structure. The cutter cap 5 has a hollow interior to protect the cutter structure 3. Both the marking cap 4 and the cutter cap 5 are provided with snap-fit ​​structures, such as annular bosses or annular grooves, which connect them to the grip structure 1.

[0027] The structure of this solution integrates the marking structure 2 and the cutting structure 3 at both ends of the grip structure 1, allowing for easy switching between uses and making it convenient to carry and store.

[0028] Based on the above implementation scheme, the label cap 4 includes a cap body 41 and a cap connecting part 42. The cap body 41 has a cylindrical structure, its shape being sufficient to cover the outside of the label connector 23. The cap connecting part 42 is located at the end of the cap body 41 away from the holding structure 1, and the cap connecting part 42 has a boss structure. The cut cap 5 can be inserted into the cap connecting part 42. At the same time, the cap body 41 can be inserted into the outside of the cut cap 5.

[0029] The purpose of this design is to provide temporary storage for the marking cap 4 and the cutting cap 5 during daily use. When marking the tarpaulin, the marking cap 4 is removed and inserted into the outside of the cutting cap 5 for marking. Conversely, when cutting the tarpaulin, the cutting cap 5 is removed and inserted into the outside of the cap connecting part 42. This prevents the caps from being lost.

[0030] Based on the above implementation plan, see Figure 4 The marking structure 2 also includes a marking connector 23 disposed between the liquid supply assembly 22 and the pen tip 21. The marking connector 23 has a large connecting hole on one side and a small connecting hole on the other side, and the large and small connecting holes are connected. The large connecting hole is used to insert the liquid supply tube, and the small connecting hole is used to insert the pen tip 21. An annular locking part is provided inside the large connecting hole, allowing the liquid supply tube and the locking part to fit together and achieve a locking connection. The pen tip 21 extends into the liquid supply tube after passing through the small connecting hole of the marking connector 23.

[0031] An annular limiting boss is provided on the outer wall of the marking connector 23. The side of the limiting boss facing the pen tip 21 is the grip side for the operator when drawing lines, and the other side is the connection side for connecting with the grip structure. An external thread structure can be provided on the outer wall of the connection side of the marking connector 23, and an internal thread is provided on the end of the grip structure 1 corresponding to the marking structure 2. The marking connector 23 and the grip structure 1 can be detachably connected by the threaded connection. In addition, an anti-slip structure for easy gripping can also be provided on the outer wall of the grip side of the marking connector 23.

[0032] Based on the above implementation plan, see Figure 5The cutting head 31 is made entirely of metal. The cutting head 31 includes two positioning portions and a blade portion 311 located between the positioning portions. The two positioning portions are a first positioning portion 312 and a second positioning portion 313. The blade portion 311 has an arc-shaped cutting edge. The first positioning portion 312 and the second positioning portion 313 are located on opposite sides of the blade portion 311. The first positioning portion 312 and the second positioning portion 313 extend away from the gripping structure 1, and the first positioning portion 312 is longer than the second positioning portion 313.

[0033] The first positioning part 312 has a pointed end away from the blade part 311, and an inclined surface is provided on the side facing the blade part 311; the second positioning part 313 has a spherical guide block at the end away from the blade part 311. The first positioning part 312, the second positioning part 313 and the blade part 311 form a complete structural part, and a stud 314 is provided on the other side of the three parts. The stud 314 is used as a connection structure for the cutting head 31.

[0034] Based on the above implementation scheme, the cutting structure 3 also includes a cutting connector 32, and the cutting head 31 is detachably connected to the holding structure 1 through the cutting connector 32. See Figure 4 and Figure 5 The shearing connector 32 consists of two cylinders with different outer diameters. A cylindrical insertion hole is formed at one end of the holding structure 1, corresponding to the smaller outer diameter cylinder. This insertion hole allows the shearing connector 32 and the holding structure 1 to be inserted. To ensure that the two do not easily detach after connection, limiting members are provided inside the insertion hole of the holding structure 1 and on the outer wall of the smaller outer diameter cylinder of the shearing connector 32. The limiting members only need to allow the two to engage and rotate; the method is not limited. This design uses a circumferentially distributed boss structure. The larger outer diameter portion of the shearing connector 32 remains on the outer side of the end of the holding structure 1. A connecting hole is provided inside the shearing connector 32 corresponding to the insertion post 314, which can be inserted into the connecting hole. The insertion post 314 adopts a long rectangular structure, and the connecting hole of the shearing connector 32 corresponds to it.

[0035] With this structure, when the blade 311 is displaced relative to the axial direction of the holding structure 1 during cutting, it can cut the tarpaulin very well. Moreover, the blade 311 can rotate, and its rotation reference axis is the axis of the cutting connector 32. This rotating structure can bring a smoother operating feel to the cutting and is less likely to cause jamming during the cutting process.

[0036] Based on the above implementation scheme, the cap connecting part 42 has a recess inside, and an LED bead is installed in the recess; a battery compartment is provided on the side of the cap body 41 facing the inside of the cap connecting part 42; the cap connecting part 42 and the cap body 41 adopt a threaded connection structure. Metal contacts are provided on the side of the cap connecting part 42 facing the battery compartment. The portion of the cap connecting part 42 located outside the cap body 41 adopts a prism structure, or an approximately cylindrical structure with symmetrical vertical cross-sections on both sides.

[0037] The cutter cap 5 is made of transparent material with a frosted surface. A reflective coating is provided at the end of the cutter cap 5 furthest from the grip structure 1, with the reflective side facing inwards. The end of the cutter cap 5 has a matching snap-fit ​​structure corresponding to the shape of the cap connector 42. This structure allows the cutter cap 5 to be fastened onto the cap connector 42. Rotating the cutter cap 5 causes the cap connector 42 to rotate, making contact between the metal contacts of the cap connector 42 and the battery in the battery compartment, illuminating the LED. Because the cutter cap 5 has a frosted surface, the light from the LED is better diffused. Furthermore, the reflective layer at the end of the cutter cap 5 reflects the light emitted by the LED towards the end of the cutter cap 5, reducing user discomfort caused by the light. Pre-drawn cutter markings can be clearly seen even in low light conditions.

[0038] Based on the above implementation scheme, and with the availability of lighting, as a further optimization of the line drawing structure 2, the ink used can also be the existing fluorescent pen ink, and the LED beads can be of an appropriate type.
