[0022] Furthermore, one end of the base ruler 1 away from the hand-held handle 3 and one end of the cursor 5 away from the hand-held handle 3 are each fixedly connected to a second measuring ruler, and the two second measuring rulers are arranged opposite to each other.

[0023] Furthermore, a fastening bolt for fixing is fixedly connected to the cursor 5, and the recording plate 2 is made of a smooth corrosion-resistant plastic plate.

[0024] Furthermore, a slide groove 9 is provided on the angle ruler 6, and the slide groove 9 is arc-shaped. The first measuring ruler 7 is composed of two measuring plates, and the two measuring plates are rotatably connected, and a fixing bolt is threadedly inserted at the rotation connection of the two measuring plates. A rotating shaft 8 is fixedly inserted on the long measuring plate of the first measuring ruler 7, and the lower end of the rotating shaft 8 extends into the slide groove 9.

[0025] Furthermore, the recording device includes a rotating plug block 10, a plug-in board 11, a pulling bar 12 and a recording pen 13. A bar groove is provided on the side of the hand-held handle 3 away from the cursor 5. The rotating plug block 10 is rotatably connected inside the bar groove. The plug-in board 11 is movably connected in the rotating plug block 10. An arc-shaped groove is provided at one end of the plug-in board 11 close to the inner wall of the bar groove, and the recording pen 13 is movably connected in the arc-shaped groove.

[0026] Furthermore, a wiper plate is fixedly connected to one end of the plug plate 11 away from the rotating plug block 10 .

[0028] Working principle: First, the user holds the entire marking ruler device stably by holding the handle 3. During the measurement process, the base ruler 1 provides a stable measurement reference, and the recording plate 2 is used to record the measured data. When performing linear measurement, the cursor 5 is slid along the main ruler 4 to locate the position to be measured. By reading the position of the cursor 5 relative to the main ruler 4, the length or distance of the object can be accurately measured; when performing angle measurement, the slide groove 9 provided on the angle ruler 6 allows the first measuring ruler 7 to rotate therein, so that the angle between the two measuring plates can be adjusted. When a specific angle needs to be measured, the user only needs to rotate the two measuring plates on the first measuring ruler 7 to the corresponding position to match it with the angle to be measured. At this time, by reading the scale on the angle ruler 6, the value of the measured angle can be accurately obtained; the second measuring ruler relatively arranged on the base ruler 1 and the cursor 5 can be used to adjust the angle. The diameter of an object is measured. When data needs to be recorded, the user can pull the pulling bar 12 to make the plug-in board 11 drive the rotating plug-in block 10 to rotate and unscrew it from the bar groove, so that the recording pen 13 can be taken out from the arc-shaped slot of the plug-in board 11, and the user can use the recording pen 13 to move on the recording board 2 to record the measured data. When the data on the recording board 2 needs to be erased, the user can remove the plug-in board 11 from the rotating plug-in block 10, so that the erasing plate on the plug-in board 11 contacts the recording board 2, and the erasing plate can easily erase the data on the recording board 2 by applying appropriate pressure. This operation is convenient and quick, and no additional cleaning tools are required. When the recording device is recycled, the bar groove on the handheld handle 3 and the supporting sheet 14 together constitute a stable fixing mechanism. When the plug board 11 and the rotating plug block 10 are installed and rotated to be completely screwed into the strip groove, the support sheet 14 will be clamped on the plug board 11 to ensure that the recording pen 13 can be stably fixed in the strip groove when not in use.
