The surveying board body 102 is used to hold surveying paper, which can be fixed to the surveying board body 102 by a magnetic stone. The storage component allows for convenient storage while also allowing adjustment of the angle of the surveying board body 102. This solves the problem that while existing technologies can store and carry the surveying board for convenience, they cannot adjust the angle of the surveying board, making it difficult to adapt to different user needs.

[0023] The shaft 104 is fixedly connected to the main frame 101 and located on one side of the main frame 101. The connecting sleeve 105 is sleeved on the outside of the shaft 104 and rotatably connected to the shaft 104. The surveying board body 102 is fixedly installed on the connecting sleeve 105. The adjusting plate 107 is fixedly connected to the main frame 101 and located inside the main frame 101. The movable bracket 106 is rotatably installed on the surveying board body 102 and cooperates with the adjusting plate 107. The limiting member restricts the movement of the surveying board body 102. The limiting mechanism is implemented, the supporting component is installed on the main frame 101, the shaft 104 is fixedly installed in the mounting groove 103 of the main frame 101, the connecting sleeve 105 has a through hole matching the diameter of the shaft 104, the connecting sleeve 105 is sleeved on the shaft 104 through the through hole, the side of the surveying board body 102 is fixedly connected to the connecting sleeve 105, the connecting sleeve 105 allows the surveying board body 102 to be flexibly flipped, facilitating the outward opening and inward retraction of the surveying board body 102, and the adjusting clip... The plate 107 is vertically provided with multiple slots. Two adjusting plates 107 are vertically installed in the mounting slots 103 of the main frame 101, arranged symmetrically. The movable bracket 106 is U-shaped, with both ends rotatably connected to the two sides of the surveying plate body 102. The bottom of the movable bracket 106 is a horizontal bar, which can be locked into any slot of the adjusting plate 107. By adjusting the position of the movable bracket 106 and the slot, the tilt angle of the surveying plate body 102 can be flexibly adjusted to meet different user needs. The limiting... The component can limit the position of the surveying board body 102, preventing it from rotating freely during storage. The support component can adjust the height of the main frame 101, thereby adjusting the position and height of the surveying board body 102. Through the cooperation of the movable bracket 106 and the adjusting plate 107, the angle of the surveying board body 102 can be adjusted. This solves the problem that although existing technologies can be stored and carried for convenience, they cannot adjust the angle of the surveying board, making it difficult to adapt to different user needs.

[0024] Secondly, the mounting sleeve 108 is fixedly connected to the main frame 101 and is located on the side of the main frame 101 near the adjusting plate 107; the pin 109 is connected to the mounting sleeve 108 through the elastic element, the elastic element is installed on the mounting sleeve 108 and supports the pin 109; the insertion hole 110 is opened on the surveying board body 102, the pin 109 cooperates with the insertion hole 110, the mounting sleeve 108 is a hollow cylinder, installed perpendicular to the main frame 101, and the pin 109...

The insertion hole 110 is opened on the surveying board body 102, and the end of the pin 109 can be inserted into the insertion hole 110. With the support of the elastic element, the end of the pin 109 can be kept in the insertion hole 110. Through the cooperation of the pin 109 and the insertion hole 110, the surveying board body 102 is limited when stored, thereby preventing the surveying board body 102 from rotating at will.

[0025] Meanwhile, the slide rod 111 extends into the mounting sleeve 108 and is slidably connected to the mounting sleeve 108, and is fixedly connected to the pin 109; the contact block 112 is fixedly connected to the slide rod 111 and is located inside the mounting sleeve 108; the spring 113 is sleeved on the outside of the slide rod 111 and is located inside the mounting sleeve 108. The slide rod 111 is a cylinder that extends into the mounting sleeve 108 and can slide and rotate. The contact block 112 is circular and is fixedly installed on one end of the slide rod 111 that extends into the mounting sleeve 108. The spring 113 is sleeved on the outside of the slide rod 111. The spring 113 is in a compressed state, and its two ends are in contact with the contact block 112 and the inner wall of the mounting sleeve 108, respectively. Through the elastic force of the spring 113, the pin 109 is elastically supported.

[0026] Additionally, the fixing cylinder 114 is fixedly connected to the main frame 101 and located on the side of the main frame 101 near the adjusting plate 107; the support leg 115 extends into the fixing cylinder 114 and is slidably connected to the fixing cylinder 114; the locking bolt 116 extends into the fixing cylinder 114 and is threadedly connected to the fixing cylinder 114. The fixing cylinder 114 is a hollow cylinder, vertically installed in the mounting groove 103 of the main frame 101, and there are two of them. The support leg 115 extends from the fixing cylinder 114. The bottom end of the 4 extends into the fixed cylinder 114. The bottom of the support leg 115 is tapered to facilitate insertion into the ground. The fixed cylinder 114 has a threaded hole. The locking bolt 116 extends into the fixed cylinder 114 through the threaded hole. When the locking bolt 116 is tightened, the end of the locking bolt 116 will abut against the surface of the support leg 115. Under the action of friction, the support leg 115 is limited. By adjusting the extension and retraction of the support leg 115, the height of the surveying board body 102 can be adjusted.

[0027] Finally, the support pad 117 is fixedly connected to the main frame 101 and located on the top of the main frame 101. The support pad 117 is a sponge pad, and there are two of them, which are symmetrically arranged on the top of the main frame 101. When the user is drawing, he / she can place his / her hands on the main frame 101. The support pad 117 can provide soft support for the user's hands, thereby improving comfort.

[0028] In this embodiment, during use, the extension and retraction of the support leg 115 is adjusted to an appropriate position, and the locking bolt 116 is tightened to lock the support leg 115. Then, the support leg 115 is inserted into the ground, at which point the main frame 101 can stand upright on the ground. Next, the pin 109 is pulled outward and rotated, causing the end of the pin 109 to disengage from the insertion hole 110. At this point, the surveying board body 102 is in an unlocked state. The surveying board body 102 is then flipped to a suitable angle, and the movable bracket 106 is engaged in the corresponding slot of the adjusting plate 107, thus limiting the position of the surveying board body 102. The surveying paper is then placed on the surveying board body. Once the measuring board body 102 is fixed with a magnetic stone, drawing can begin. When the angle of the measuring board body 102 needs to be adjusted, the position of the movable bracket 106 can be adjusted. When storing, remove the movable bracket 106 from the slot of the adjusting plate 107, then rotate the measuring board body 102 into the mounting slot 103 of the main frame 101. After that, pull the pin 109 outward and rotate it to align with the insertion hole 110. Release the pin 109, and under the elastic force of the spring 113, the end of the pin 109 is inserted into the insertion hole 110, thereby limiting the position of the measuring board body 102. Finally, reset the support leg 115 to complete the storage. This application allows for convenient storage and portability. Furthermore, the angle of the surveying board body 102 can be flexibly adjusted to meet user needs. This solves the problem that while existing technologies can be stored and carried conveniently, they cannot adjust the angle of the surveying board, making it difficult to adapt to different user requirements.
