A surveying pen 3 is provided on the right side of the main board 1 for recording and marking construction design measurements. A second ruler 11 is fixedly connected to the lower rear side of the main board 1 for cooperating with the first ruler 2 to extend the measurable length of the measuring device. A second magnetic strip 111 is fixedly connected to the upper right side of the second ruler 11 for cooperating with the first magnetic strip 21 to set the position of the first ruler 2. A third magnetic strip 112 is fixedly connected to the left end of the second ruler 11 for cooperating with the first magnetic strip 21 to restrict the position of the first ruler 2.

[0035] like Figure 4 and Figure 6 As shown, the front side of the main board 1 is provided with a sliding groove 12, which is used to connect and move the first ruler plate 2. The connecting rod 22 is slidably connected to the sliding groove 12, which is used to move the first ruler plate 2. The front end of the sliding groove 12 is provided with an inclined groove 121, which is used to connect the first ruler plate 2 and the second ruler plate 11, and to facilitate the attraction of the first magnetic strip 21 and the third magnetic strip 112. The connecting rod 22 is slidably connected to the inclined groove 121.

[0036] Please see Figure 4 and Figure 5A magnetic strip 21 is fixedly connected to the right end of the first ruler plate 2, which is used to limit the first ruler plate 2. A connecting rod 22 is fixedly connected to the front right side of the first ruler plate 2, which is used to connect the first ruler plate 2 and the main plate 1. A connecting block 221 is fixedly connected to the front side of the connecting rod 22, which is used to limit the first ruler plate 2 and prevent the connecting rod 22 from detaching from the main plate 1. The shapes of the slide groove 12 and the inclined groove 121 are adapted to the connecting rod 22 and the connecting block 221.

[0037] Please see Figure 7 The surveying pen 3 includes a pen barrel 31, which is used for recording or drawing during construction surveying. A limiting block 32 is fixedly connected to the right side of the pen barrel 31, which is used to connect the surveying pen 3. A push block 33 is fixedly connected to the front side of the limiting block 32. The front side of the push block 32 is textured to make it more slip-resistant and easier to push. A first magnetic ring 34 is fixedly connected to the left side of the limiting block 32. It can be attracted to a second magnetic ring 15, thereby fixing the position of the surveying pen 3.

[0038] Furthermore, a storage slot 13 is provided on the right side of the main board 1, which is used to store the surveying pen 3. A limiting slot 14 is provided on the right side of the storage slot 13, which is used to connect with the limiting block 32. The limiting block 32 is movably connected to the limiting slot 14. A second magnetic ring 15 is fixedly connected to the left side of the limiting slot 14, which is used to fix the position of the surveying pen 3 by the first magnetic ring 34. An auxiliary port 16 is provided on the front side of the limiting slot 14, which is used to assist in the connection and disconnection of the push block 33. The push block 33 is movably connected to the auxiliary port 16.

[0039] Working principle: When it is necessary to extend the measuring length of the measuring device, pull the first ruler plate 2 to the left. At this time, the first magnetic strip 21 will separate from the second magnetic strip 111, and the connecting rod 22 and the connecting block 221 will slide in the slide groove 12. When the connecting rod 22 and the connecting block 221 move to the inclined groove 121, they will move along the direction of the inclined groove 121, so that the first magnetic strip 21 and the third magnetic strip 112 are attracted together, and the first ruler plate 2 and the second ruler plate 11 are joined together, thus increasing the measuring range of the measuring device. When the measuring device needs to be put away after use, push the first ruler plate 2 to the left. At this time, the connecting rod 22 and the connecting block 221 on the first ruler plate 2 will slide along the inclined groove 121 to the slide groove 12, and the first magnetic strip 21 will be attracted together with the second magnetic strip 112. The third magnetic strip 112 separates, and then the connecting rod 22 and connecting block 221 on the first ruler plate 2 slide along the slide groove 12 to the right until the first magnetic strip 21 and the second magnetic strip 111 are attracted and fixed together again. When it is necessary to record the measurement results or draw them, simply push the push block 33 to the right, so that the push block 33 drives the limit block 32 to disengage from the limit groove 14. At this time, the first magnetic ring 34 will separate from the second magnetic ring 15, and the measuring pen 3 can be taken out from the main board 1. After use, simply insert the pen barrel 31 of the measuring pen 3 back into the storage slot 13, so that the limit block 32 is pressed into the limit groove 14, and the push block 33 is inserted into the auxiliary port 16. At this time, the first magnetic ring 34 will be attracted and fixed together with the second magnetic ring 15, thereby fixing the measuring pen 3 to the main board 1.
