Mechanical design is an important part of mechanical engineering, the first step of mechanical production, and the most important factor determining the performance of a machine. Various tool rulers are often needed in the work of mechanical design.

[0003] When the existing tool ruler is in use, the thickness jaws of the tool ruler are usually clamped on the outside of the part to measure its thickness. However, the lengths of the thickness jaws of the existing tool rulers are generally fixed and cannot be flexibly adjusted. When measuring parts with larger sizes or irregular shapes, they cannot be effectively clamped at the position to be measured. Moreover, the lengths of the existing tool rulers are relatively fixed and cannot be extended or contracted. When measuring objects that are too long or too large, multi-segment measurement is required, and the whole process is rather troublesome, which is likely to affect work efficiency and measurement accuracy and cannot meet the use requirements.

[0020] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model in conjunction with the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0021] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification. Embodiment

[0022] As Figures 1-4 shown, the present utility model provides a technical solution: a mechanical design tool ruler, including a tool ruler body 1, a sliding frame 2 is movably installed on the outer side of the tool ruler body 1, thickness measuring jaws 3 are symmetrically arranged at one end of the bottom of the tool ruler body 1 and the sliding frame 2, a connection component is arranged at the top of the inner side of the thickness measuring jaw 3, one end of the connection component is fixedly connected with an extension measuring jaw 4, a fixed rod 5 is arranged inside the thickness measuring jaw 3, a movable frame 6 is rotatably connected to the outer side of the fixed rod 5, a first bolt 7 is installed on one side of the thickness measuring jaw 3, an extension ruler 10 is movably installed inside the tool ruler body 1, wedge-shaped grooves 11 are symmetrically formed at the top and bottom of one end of the extension ruler 10, movable rods 12 are symmetrically arranged at the top and top of one end of the tool ruler body 1, one end of the movable rod 12 movably penetrates through the tool ruler body 1 and is connected with a wedge-shaped block 15, the wedge-shaped block 15 is clamped inside the wedge-shaped groove 11, and a second spring 13 is sleeved on the outer side of the movable rod 12.

[0023] In this embodiment, by turning the first bolt 7, the movable frame 6 is pushed to rotate on the fixed rod 5, and then the extended measuring jaw 4 is pushed to slide outwards from the inside of the thickness measuring jaw 3, thereby extending the length of the thickness measuring jaw 3 so that it can be correctly clamped at the position to be measured of parts with different sizes or irregular shapes, thus improving the versatility of the tool ruler, reducing the usage difficulty, improving the work efficiency, and meeting the actual usage requirements. By sliding the extension ruler 10 inside the tool ruler body 1, the length of the ruler body can be extended or shortened, which is convenient for measuring parts with different sizes. Utilizing the elasticity of the second spring 13, the movable rod 12 can be pushed to slide on the tool ruler body 1, prompting the wedge block 15 to insert into the wedge groove 11 to fix the extension ruler 10 and prevent it from falling off, thereby effectively improving the convenience and stability of using the tool ruler, and enhancing its versatility and overall work efficiency. Embodiment

[0024] As Figures 1-4 shown, the connecting component includes a telescopic rod 8, a first spring 9 is sleeved outside the telescopic rod 8, a limiting plate 14 is connected to the top of the movable rod 12, a pull ring 16 is rotatably connected to the outside of the limiting plate 14, a mounting frame 18 is fixedly installed at the top of the sliding frame 2 through bolts, a protractor 19 is arranged at the top of the mounting frame 18, a cushion block 21 is arranged on one side of the tool ruler body 1, a limiting block 22 is fixedly connected to one end of the extension ruler 10, internal diameter measuring jaws 17 are arranged at one end of the top of the tool ruler body 1 and one end of the sliding frame 2, a glass plate 23 is arranged on the surface of the sliding frame 2, and a second bolt 20 is arranged at the bottom of the sliding frame 2.

[0025] In this embodiment, due to the contraction and rebound characteristics of the first spring 9, when the first spring 9 contracts, it can drive the extended measuring jaw 4 connected to the telescopic rod 8 to quickly reset, without complex manual operations, reducing the usage difficulty. The limiting plate 14 can prevent the movable rod 12 from falling off the tool ruler body 1, improving its stability. By pulling the pull ring 16, the second spring 13 can be quickly contracted to pull the wedge block 15 out of the wedge groove 11, releasing the limit on the extension ruler 10, thereby reducing the usage difficulty. By attaching the protractor 19 to the surface of the object to be measured, the angle of the object to be measured can be measured. At the same time, by inserting the internal diameter measuring jaws 17 into the pipe and sliding the sliding frame 2, the internal diameter of the pipe can be measured, thus enhancing the functionality of the tool ruler and broadening its usage scenarios. The cushion block 21 and the limiting block 22 can ensure the flatness of the side surface of the tool ruler body 1, enabling the tool ruler body 1 to better fit on the surface of the object to be measured. At the same time, the limiting block 22 can limit the extension ruler 10 to prevent the extension ruler 10 from being completely inserted into the inside of the tool ruler body 1 when it contracts, thereby enhancing the convenience of using the tool ruler. The glass plate 23 can facilitate observing the scale on the surface of the tool ruler body 1 when the sliding frame 2 slides. By turning the second bolt 20, the sliding frame 2 can be limited, thereby improving the measurement accuracy.

[0026] Working principle of this embodiment: When in use, first, manually pull the extension ruler 10 and extract it from the inside of the tool ruler body 1. When the extension ruler 10 is fully extracted, affected by the resilience of the second spring 13, the movable rod 12 will slide on the tool ruler body 1, pushing the wedge block 15 into the inside of the wedge groove 11 to fix and limit the extension ruler 10. When the tool ruler body 1 needs to be folded and contracted, the limit block 22 can be pushed or the pull ring 16 can be pulled to make the second spring 13 contract under force, and the wedge block 15 disengages from the inside of the wedge groove 11, then insert the extension ruler 10 into the inside of the tool ruler body 1 to shorten the length of the tool ruler body 1. Finally, turn the first bolt 7 to push the movable frame 6 to rotate on the fixed rod 5, squeezing the extended measuring jaw 4 to slide outwards from the inside of the thickness measuring jaw 3, thereby extending the length of the thickness measuring jaw 3 so that it can be stuck at the position to be measured of parts with different sizes or irregular shapes, and then measure the thickness of the parts. When it is necessary to retract the extended measuring jaw 4, then screw out the first bolt 7 outwards to make the telescopic rod 8 and the first spring 9 contract, driving the extended measuring jaw 4 to quickly slide into the thickness measuring jaw 3, thus completing the use of the mechanical design tool ruler.
