[0032] like Figures 1 to 4As shown, according to the embodiment of the utility model, a multifunctional tape measure 100 is proposed, which includes a housing 10, a ruler 20 that can be accommodated in the housing 10, a roller 30 and a marking portion 40, wherein the housing 10 has a retractable opening 101 and a retracting mechanism (not shown in the drawings), the retracting mechanism is arranged inside the housing 10, the retractable opening 101 is connected to the inside of the housing 10, the connecting end of the ruler 20 is arranged inside the housing 10 and connected to the retracting mechanism, the extended end of the ruler 20 is arranged outside the housing through the retractable opening 101, the ruler 20 has a retracted state and an unfolded state that can be switched to each other, and the retracting mechanism drives the ruler to have a tendency to switch to the retracted state. The roller 30 is rotatably arranged at the extended end of the ruler 20, the axis of the roller 30 is perpendicular to the ruler 20, the marking portion 40 is detachably connected to the housing 10, and the axis of the marking portion 40 is parallel to the axis of the roller 30.

[0033] According to the multifunctional tape measure 100 of this embodiment, the line drawing part 40 is connected to the tape measure housing 10 in a detachable manner, and its axis is parallel to the axis of the roller 30. When in use, the user can slide the roller 30 on the surface of the measured object, and use the rotation of the roller 30 to guide the line drawing part 40 to move along the contour of the complex shape. Since the axis of the line drawing part 40 is parallel to the axis of the roller 30, the stability and accuracy of the line drawing part 40 when drawing the contour can be guaranteed. If a specific circular or curved shape needs to be drawn, the user can adjust the relative position or angle between the roller 30 and the line drawing part 40 so that the line drawing part 40 moves along a predetermined trajectory, thereby accurately drawing the desired complex shape contour. The utility model is provided with a rotatable roller 30 and a detachable line drawing part 40, so that the tape measure can not only perform traditional straight-line distance measurement, but also can be used to draw the contour of complex shapes, meeting more diverse measurement and drawing needs.

[0034] In some embodiments, a through hole 31 is provided on the roller 30, and the through hole 31 is coaxially arranged with the roller 30, and a positioning cone can be inserted into the through hole 31. By inserting the positioning cone into the through hole 31, the positioning cone can be fixed at the center of the circle to be drawn, and the radius of the center of the circle can be determined by adjusting the length of the ruler 20. In this way, the user can draw an accurate circular outline to meet the needs of circular patterns or marks. This technical solution simplifies the process of drawing a circle, improves work efficiency, and can achieve accurate circle drawing without additional tools, thereby enhancing the practicality and versatility of the tape measure.

[0035] It is understandable that the outside of the positioning cone can be designed with threads or slots to match the threads or buckles inside the through hole 31. When in use, the positioning cone is rotated or pressed so that its threads are engaged with the threads of the through hole 31 or the slots are locked with the buckles, thereby achieving detachable fixation. This structure not only ensures the stability of the positioning cone during use, but also facilitates the user to quickly replace the positioning cone as needed, thereby improving the flexibility and ease of use of the tool.

[0036] It is understandable that the multifunctional tape measure 100 further includes a limit portion 60, which is disposed on the side of the housing 10 having the retractable opening 101, and the limit portion 60 is used to abut against the object to be measured, and a line drawing tool 32 can be inserted into the through hole 31. By adding the limit portion 60 to the multifunctional tape measure 100 and abutting against the object to be measured, the user can move the line drawing tool 32 inserted in the through hole 31 inward along the edge of the object to be measured at equal distances, thereby drawing equidistant contour lines. This embodiment enables the multifunctional tape measure 100 to be used not only for conventional straight line measurement and circular drawing, but also for more complex surveying and mapping tasks, such as drawing equidistant contour lines on the surface of an irregularly shaped object. This functional expansion significantly improves the applicability and work efficiency of the multifunctional tape measure 100, and meets the needs of users in a variety of different work scenarios.

[0037] Specifically, there are two limit parts 60, and the two limit parts 60 are symmetrically arranged on opposite sides of the receiving opening 101. This design allows the user to adjust the positions of the two limit parts 60 according to the size and shape of the object to be measured, so as to ensure that the line drawing tool 32 can move inward or outward along the edge of the object to be measured at equal distances, thereby drawing accurate equidistant contour lines or edge lines. This embodiment improves the adaptability and accuracy of the multifunctional tape measure 100 in complex shape measurement and drawing, allowing users to use the tape measure for accurate edge tracking and contour drawing in a wider range of application scenarios.

[0038] In some embodiments, the limiter 60 is designed as a pin structure that can rotate along the axis parallel to the roller 30. This design allows the limiter 60 to rotate along the axis parallel to the roller 30 to adapt to different usage scenarios and object shapes. The user can adjust the position of the limiter pin by rotating it according to the specific size and shape of the object to be measured, so that the line drawing tool 32 can move inward or outward at equal distances along the edge of the object to be measured while maintaining a certain distance. This rotatable limiter pin structure increases the flexibility and applicability of the tape measure, allowing it to more accurately and efficiently draw contour lines or edge lines of equal distances on objects of various shapes.

[0039] Specifically, the housing 10 may be provided with a slide groove or a guide rail and a matching fastening mechanism, such as a screw button or a buckle, to allow the pin structure to slide along the axis direction of the roller 30 or parallel to the axis direction of the roller 30 and lock in an appropriate position. This design improves the flexibility and adaptability of use, so that the user can adjust the position of the limit pin according to different measurement and drawing requirements, and then adjust the relative position of the line drawing tool 32 and the object to be measured to ensure accurate measurement and drawing.

[0040] It is understandable that the axis of the roller 30 is perpendicular to the ruler 20. This design enables the roller 30 to keep the ruler 20 stable and accurately aligned when rotating. This embodiment improves the accuracy of measurement and drawing operations, especially when tracing straight lines or curves. In addition, this solution also facilitates users to ensure accurate alignment of marks when using a tape measure for marking and drawing operations, thereby improving work efficiency and the reliability of measurement results.

[0041] It is understandable that the housing 10 is provided with a level 70. The housing 10 is provided with a level 70, which improves the accuracy and convenience of the multifunctional tape measure 100 when measuring. Through the level 70, the user can ensure that the position of the tool remains horizontal when using the tape measure to mark lines, measure or draw circles, thereby improving the accuracy and efficiency of the operation. This design is particularly advantageous in scenarios where it is necessary to accurately measure a horizontal plane or mark a horizontal line, greatly enhancing the practical value and user experience of the multifunctional tape measure 100.

[0042] In some embodiments, the housing 10 includes a first housing body 11 and a second housing body 12, and the first housing body 11 and the second housing body 12 are enclosed to form a storage cavity, and the retracting mechanism is accommodated in the storage cavity. The first housing 10 and the second housing 10 can be easily assembled and disassembled, which enhances the convenience of maintenance and the ability to replace the tape measure part. This design improves the durability and user-friendliness of the tape measure, making it more adaptable to a variety of usage scenarios and extending the service life of the product.

[0043] Specifically, the first shell body 11 and the second shell body 12 can be connected by a threaded connection. The first shell body 11 is provided with studs, and the second shell body 12 is provided with studs corresponding to the studs on the first shell body 11. After the two studs are connected, the screws are screwed in to tighten the first shell body 11 and the second shell body 12.

[0044] In some embodiments, the multifunctional tape measure 100 further includes a locking button portion 50, which is movably disposed on the housing 10. The locking button portion 50 has a locked state and an unlocked state. In the locked state, the locking structure of the locking button portion abuts against the ruler 20 to fix the current position of the ruler 20. In the unlocked state, the locking structure is separated from the ruler 20, and the ruler 20 can switch between the rolled-up state and the unfolded state. The locking button portion 50 partially passes through the housing 10 to connect the ruler 20, so that the ruler 20 can be retracted. Specifically, a locking mechanism that is easy to operate and can provide a stable lock can be introduced. The mechanism includes designing a locking button to ensure that the user is easy to operate, and may have a textured surface to provide a better grip. In addition, the locking mechanism can have a quick release function, so that locking and unlocking the ruler 20 is faster and more efficient, improving the convenience during use.

[0045] In some embodiments, a ruler hook 80 is provided at the protruding end of the ruler bar 20, and the ruler hook 80 is used to cooperate with the object to be measured.

[0046] In some embodiments, the multifunctional measuring tape 100 further includes a hanging strap connected to the housing 10 .

[0047] In some embodiments, the multifunctional tape measure 100 further includes a hook connected to the housing 10 .

[0048] Specifically, the line drawing unit 40 may be a component equipped with a brush, pencil or other marking tool, which can be rotated or moved along a guide rail or a fixed point to draw lines on the surface of an object. The line drawing unit 40 may include an adjustable brush or pencil socket, allowing the user to replace or adjust the length and angle of the line drawing tool 32 as needed to meet different drawing needs.
