[0035] Taking a measuring tool for drawing by measuring length as an example, it is usually used when drawing. During the drawing process, the user needs to bring their own drawing pencil 4, and after the drawing is completed, the pencil 4 and the measuring tool need to be stored separately, which is very inconvenient.

[0036] To address the aforementioned problems, this utility model proposes a multifunctional measuring tool 100, aiming to provide a more convenient multifunctional measuring tool 100 for use and storage. Figures 1 to 8 This is a schematic diagram of an embodiment of the multifunctional measuring tool 100 of this utility model.

[0037] Please refer to Figures 1 to 8This utility model proposes a multifunctional measuring tool 100, including a fixed shaft 1, a ruler body, and a pencil 4. The ruler body includes a first ruler body 2 and a second ruler body 3. The first ruler body 2 is rotatably mounted on the fixed shaft 1, and the second ruler body 3 is fixedly mounted on the fixed shaft 1. The first ruler body 2 is provided with a first marking part 21, and the second ruler body 3 is provided with a second marking part 31. The first ruler body 2 is provided with a receiving cavity 22 with an opening. A magnetic suction part 221 is provided in the receiving cavity 22. The pencil 4 has a magnetically conductive part 421. The pencil 4 is housed in the receiving cavity 22 and is magnetically fixed to the magnetically conductive part 421 and the magnetically suction part 221.

[0038] The present invention provides a multifunctional measuring tool 100, comprising a fixed shaft 1, a ruler body, and a pencil 4. The ruler body includes a first ruler body 2 and a second ruler body 3 connected by the fixed shaft 1. The first ruler body 2 can rotate relative to the second ruler body 3. A receiving cavity 22 is provided on the first ruler body 2, and a magnetic suction part 221 is provided in the receiving cavity 22. Correspondingly, the pencil 4 is provided with a magnetic conductive part 421. The pencil 4 is received in the receiving cavity 22 and fixed by the magnetic attraction part 221 through the magnetic attraction part 221. The pencil 4, which is used for drawing, is integrated into the measuring tool as an integrated design, which can bring convenience to the user in terms of use and storage, reduce the cumbersomeness of operation, and improve the overall user experience.

[0039] It is understood that the magnetic conductive part 421 on the pencil 4 is located on the body 42 of the pencil 4. The material of the magnetic conductive part 421 is a conventional magnetic conductive material, such as iron, nickel-iron alloy, cobalt alloy, etc. It should be noted that the pencil 4 can adopt an integrated design, that is, the pencil tip 41 and the body 42 of the pencil 4 are a whole, or it can adopt a separate design, that is, the pencil tip 41 and the body 42 of the pencil 4 can be disassembled. This application does not limit this. In one embodiment of this application, the pencil tip 41 and the body 42 of the pencil 4 are connected by threads. One end of the body 42 has a threaded hole, and the pencil tip 41 has a stud. The two are screwed together to achieve disassembly and assembly. This design can effectively reduce the cost of use, because the pencil tip 41 will gradually wear down during the drawing process, while the body 42 is usually made of metal, which is more durable and more expensive. With the detachable design, the user only needs to replace the worn pencil tip 41, without replacing the entire pencil 4, thereby greatly saving resources and costs. Secondly, this structure improves the lifespan and sustainability of pencil 4, reducing the likelihood of discarding the entire pencil 4 due to wear and tear of the tip 41, which aligns with environmental protection principles. Furthermore, the detachable design increases the flexibility and applicability of pencil 4, allowing users to choose tips 41 of different hardness or materials according to different drawing needs, further enhancing the practicality and user experience of pencil 4.

[0040] Furthermore, to improve the practicality of pencil 4, a cutting element 422 is provided at the end of the pencil body 42 away from the tip 41. For details, please refer to further documentation. Figure 4A sharp metal tip is machined at the end of the pencil body 42. This tip has sufficient hardness and sharpness to easily cut through common materials such as cardboard boxes and plastic packaging. The advantage of this design is that it expands the function of the pencil 4 from simple drawing to the realm of everyday tools, allowing one pencil 4 to simultaneously meet the needs of drawing and unpacking, reducing the inconvenience of carrying extra tools and increasing the pencil 4's versatility and frequency of use. At the same time, the durable and easily damaged metal cutting component 422 ensures its long-term usability.

[0041] The multi-functional measuring tool 100 of this application has a first marking part 21 on its first ruler body 2 and a second marking part 31 on its second ruler body 3. For details, please refer to further reference. Figure 1 The first marking section 21 and the second marking section 31 correspond to imperial units and metric units, respectively. This design allows it to meet the needs of different user groups and application scenarios. In an international context, different countries and regions may use different units of measurement. Imperial units are still widely used in certain fields (such as mechanical engineering and electronic equipment), while metric units are the internationally recognized standard units. By providing markings for both units on the same measuring tool, users can flexibly choose to use imperial or metric units for measurement according to their actual needs, eliminating the need to carry additional measuring tools. This improves the tool's versatility and practicality, reduces errors and inconvenience caused by unit conversion, and enhances measurement efficiency and accuracy.

[0042] The first ruler 2 can rotate around a pivot point to form an arbitrary angle with the second ruler 3, or to be collinear with the second ruler 3, thereby expanding the length that can be drawn and measured. Specifically, this rotatable structure allows users to freely adjust the angle of the rulers according to different drawing and measurement needs, enabling more precise drawing and measurement of various lengths and angles. For example, when drawing angle diagrams or measuring angles, users can rotate the first ruler 2 to the desired angle and then use the second ruler 3 as a reference, making drawing and measurement tasks more convenient. Furthermore, when measuring straight line lengths, the first ruler 2 and the second ruler 3 can be collinear, thus expanding the range of measured lengths. This design not only improves the practicality and accuracy of the measuring tool but also increases its applicability in different scenarios, allowing one tool to meet multiple measurement and drawing needs, reducing the inconvenience of carrying multiple tools and improving work efficiency.

[0043] In the technical solution of this application, in addition to measuring and drawing using the first ruler 2 and the second ruler 3, it also has several other additional functions.

[0044] In one embodiment of this application, the multifunctional measuring tool 100 also includes calipers, which can measure various dimensions such as outer diameter and depth, thus overcoming the limitation that the first ruler 2 and the second ruler 3 can only measure straight line lengths. For details, please refer to further reading. Figure 1 and Figure 5 The second ruler body 3 has a waist-shaped hole 32. The caliper includes a caliper body 51, a sliding pin 52, and a caliper head 53. The sliding pin 52 is slidably disposed in the waist-shaped hole 32. The caliper body 51 has a third marking part 511. The caliper head 53 can abut or disengage from the end of the second ruler body 3 away from the fixed axis 1. When performing a measurement operation, the sliding pin 52 is pressed down, causing it to slide within the waist-shaped hole 32, thereby extending the caliper head 53. The object to be measured is placed in the gap between the caliper head 53 and the end of the second ruler body 3, and the measurement can be achieved. The size of the object is the sum of the reading of the third marking part 511 and the reading of the fifth marking part 33. Calipers have higher precision, typically reaching 0.01 mm or even higher, making them suitable for precision measurement. In addition, the structural design of calipers makes them more stable during measurement, reducing human error and improving the accuracy and reliability of the measurement. Calipers are superior to rulers in terms of versatility, precision, and stability, and are particularly suitable for fields such as machining and precision manufacturing where high measurement accuracy is required.

[0045] In one embodiment of this application, the second ruler 3 is equipped with a droplet level 7. For details, please refer to further details. Figure 1 When measuring or drawing, users can simultaneously check if the tool is level, ensuring accuracy. For example, in construction, furniture assembly, or machinery assembly, a level is an indispensable tool. Integrating level functionality into a measuring tool reduces the need to carry additional tools, improving work efficiency. Furthermore, this integrated design reduces errors that may be introduced by switching tools, enhancing overall ease of use and practicality.

[0046] In one embodiment of this application, the multifunctional measuring tool 100 further includes a roller ruler 6; for details, please refer to further details. Figure 6 and Figure 7The roller ruler 6 includes a fixed base 61 and a measuring wheel. The fixed base 61 is fixedly mounted on a fixed shaft 1, and the measuring wheel is rotatably mounted on the fixed shaft 1. The measuring wheel and the fixed base 61 together form a mounting cavity 621. In operation, the user simply places the measuring wheel of the roller ruler 6 on the curve or arc surface to be measured and gently rolls the measuring wheel. The tool will then calculate the actual length based on the number of rotations and the circumference of the measuring wheel. The advantage of this design is that it can accurately measure the lengths of curves and arcs that are difficult to measure with traditional rulers or calipers, performing exceptionally well in scenarios such as measuring pipes, bends, and irregularly shaped object surfaces. Compared to traditional measuring tools, the roller ruler 6 is not only easy to operate but also provides more accurate measurement results, making it particularly suitable for fields such as construction, machining, and artistic creation, offering users a more flexible and efficient measurement solution.

[0047] Furthermore, the mounting base 61 has a mounting shaft 611 facing the measuring wheel, and a torsion spring 63 is sleeved on the mounting shaft 611. The inner circumferential wall of the measuring wheel has a notch, and one end of the torsion spring 63 elastically abuts against the inner circumferential wall of the measuring wheel. When the measuring wheel rotates one revolution, one end of the torsion spring 63 will pass through the notch of the measuring wheel once, thus producing a clicking sound. This helps the user record the number of revolutions of the measuring wheel, making it easier for the user to calculate the length of the area to be measured. To prevent relative sliding between the measuring wheel and the object being measured during the measurement process, a rubber ring 64 is sleeved on the outer circumferential wall of the measuring wheel. For details, please refer to further documentation. Figure 6 When the measuring wheel rolls on the surface of the object to be measured, it comes into contact with the object through the rubber ring 64. Since the rubber ring 64 can generate a large frictional force, it avoids relative sliding between the measuring wheel and the object to be measured, thus preventing the measurement accuracy from being affected.

[0048] In one embodiment of this application, the multifunctional measuring tool 100 further includes a protractor 8; specifically, please refer to further details. Figure 1 and Figure 8 The protractor 8 includes a scale 81 and a pointer 82. The scale 81 is rotatably mounted on the mounting shaft 611 and connected to the first ruler 2. The pointer 82 is fixed on the mounting shaft 611 and located above the scale 81. Since the scale 81 is rotatably mounted on the fixed shaft 1 and connected to the first ruler 2 through the first connecting post 811, when the first ruler 2 rotates around the fixed shaft 1, it will simultaneously drive the scale 81 to rotate relative to the pointer 82. At this time, the pointer 82 will point to one of the graduations on the fourth mark section 62 on the scale 81. The graduations on the scale 81 range from 0 to 18. Multiplying the graduation value pointed to by the pointer 82 by 10 gives the measured angle.

[0049] In one embodiment of this application, the first ruler body 2 is provided with a plurality of drawing holes 23. For details, please refer to further details. Figure 1Multiple drawing holes 23 are spaced apart along the length of the first ruler 2, with a center distance of 5mm between each pair of adjacent drawing holes 23. They can be used with a pencil 4. Inserting the pencil tip 41 into one of the drawing holes 23 and using the pencil 4 to push the first ruler 2 to rotate around the fixed axis 1 completes the drawing of a semicircle. Then, rotating the second ruler 3 180° and then rotating the first ruler 2 completes the drawing of a circle. Switching between different drawing holes 23 allows for the drawing of circles with different radii.

[0050] In one embodiment of this application, the second ruler 3 is further provided with a bottle opener notch 34. For details, please refer to further details. Figure 1 This multi-functional measuring tool not only provides measurement capabilities but also allows for easy opening of beer bottle caps or other containers with lids. It integrates a commonly used bottle-opening function with a measuring tool, eliminating the need for users to carry a separate bottle opener, reducing the number of tools required and increasing the tool's practicality. For example, in outdoor picnics, parties, or work settings, this integrated design allows users to easily open beverage bottles, increasing the tool's versatility and convenience while saving space and enhancing the user experience.

[0051] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
