The two ends of the second spring 413 are fixedly connected to the embedded block 412 and the built-in pressure plate 414 respectively. The embedded block 412 is slidably connected to the built-in pressure plate 414, and a fifth bearing 411 is installed on the upper surface of the embedded block 412.

[0053] A first threaded rod 49 is inserted into the interior of the fifth bearing 411, and the first threaded rod 49 is rotatably connected to the embedded block 412 through the fifth bearing 411. The first threaded rod 49 is inserted into a first threaded hole 415 opened on the upper surface of the second rectangular plate 46, and the first threaded rod 49 and the second rectangular plate 46 are threadedly connected.

[0054] Working principle: When the surveying and mapping device is in use, the device is placed on the ground to be surveyed, and the adjusting screw 5 at the corresponding position is rotated, and the base 1 can be adjusted to a level by observing the universal level placed on the upper surface of the base 1;

[0055] The latch rod 34 is slid out from the inside of the connecting plate 33, so that the first tooth plate 39 can be rotated in the direction away from the first gear 31. When the first tooth plate 39 is rotated to a suitable position, a force is applied to the L-shaped support rod 21, so that the L-shaped support rod 21 can slide inside the first rectangular frame 24, thereby achieving the horizontal distance between the L-shaped support rod 21 and the base 1. When the position of the L-shaped support rod 21 is adjusted, the first tooth plate 39 is rotated in the opposite direction, so that the first tooth plate 39 is meshed with the surface of the first gear 31, and the latch rod 34 is inserted into the inside of the connecting plate 33, so as to achieve the effect of limiting the position of the first tooth plate 39;

[0056] The first threaded rod 49 is rotated under the action of the first threaded hole 415 so that the embedded block 412 drives the built-in pressure plate 414 to move upward through the second spring 413. After the recording pen 42 is inserted into the second through hole 416 and the position of the recording pen 42 is adjusted, the first threaded rod 49 is rotated to move the embedded block 412 downward. When the surfaces of the built-in pressure plate 414 and the recording pen 42 are in contact with each other, the built-in pressure plate 414 squeezes the recording pen 42 under the action of the elastic potential energy of the second spring 413, thereby fixing the position of the recording pen 42.

[0057] One end of the continuous paper on the surface of the paper roll 26 is fixed on the surface of the winding roller 220, and the first motor 214 is connected to an external power supply. The placement process of the line will not affect the accuracy of the surveying and mapping. The operation controller starts the first motor 214. The operation of the first motor 214 drives its output shaft to rotate the hexagonal joint 227, thereby driving the lower circular shaft 217 to rotate. The rotation of the lower circular shaft 217 drives the second hexagonal rod 221 to rotate synchronously, thereby driving the winding roller 220 to rotate synchronously. During the rotation of the winding roller 220, the paper on the surface of the paper roll 26 is wound around the surface of the winding roller 220. As the winding roller 220 winds the paper on the surface of the paper roll 26, the paper roll 26 is driven to rotate accordingly. The rotation of the paper roll 26 drives the external threaded sleeve 23 to rotate synchronously, thereby driving the first rectangular frame 24 to rotate. The rotation of the first rectangular frame 24 drives the L-shaped support rod 21 to rotate synchronously.

[0058] During this process, under the action of the gravity of the rectangular counterweight block 48, one end of the tilting rod 47 has a suitable force on the second rectangular plate 46, so that the second rectangular plate 46 drives the recording pen 42 to move in the direction of the paper roll 26. When one end of the recording pen 42 is in contact with the paper on the surface of the paper roll 26, under the action of the rectangular counterweight block 48, there is a suitable force between one end of the recording pen 42 and the paper on the surface of the paper roll 26. As the paper on the surface of the paper roll 26 is continuously wound around the surface of the winding roller 220, one end of the recording pen 42 draws continuous lines on the paper. As the paper roll 26 continues to rotate, the paper on the surface of the paper roll 26 continues to decrease. Under the action of the gravity of the rectangular counterweight block 48 and the tilting setting of the tilting rod 47, there is always a force between the recording pen 42 and the paper roll 26, thereby ensuring that the recording pen 42 is in contact with the paper on the surface of the paper roll 26. The L-shaped support rod 21 drives the roller 22 to move synchronously under the action of rotation, and when the roller 22 contacts the ground, the L-shaped support rod 21 can move vertically during the rotation when the ground is tilted. When the L-shaped support rod 21 moves vertically during the rotation, the vertical movement of the L-shaped support rod 21 drives the first rectangular frame 24 to move, and the movement of the first rectangular frame 24 drives the external threaded pipe sleeve 23 to move, thereby driving the paper roll 26 to move vertically. According to the horizontal situation of the ground, the paper roll 26 can be moved vertically, and when the paper roll 26 moves vertically during the rotation, the recording pen 42 can draw a tortuous and continuous line segment on the paper on the surface of the paper roll 26, which is conducive to drawing lines on the paper on the surface of the paper roll 26 by the recording pen 42 during the rotation of the L-shaped support rod 21. The leveling situation of the ground can be reflected by observing the tortuous path of the line segment;

[0059] Since the first hexagonal rod 28 is inserted into the first hexagonal groove 27, and the built-in pipe sleeve 29 is sleeved on the surface of the first hexagonal rod 28, when the external threaded pipe sleeve 23 and the first rectangular frame 24 are rotating, the first hexagonal rod 28 and the built-in pipe sleeve 29 do not rotate, so that the first gear 31 does not rotate, and the L-shaped support rod 21 drives the slider 312 to rotate synchronously during the rotation process, thereby driving the first tooth plate 39 to rotate along the L-shaped support rod 21 with the external threaded pipe sleeve 23 as the axis. Since the first gear 31 and the first tooth plate 39 are meshed and connected, when the first tooth plate 39 is rotating, the first gear 31 can pull the rotating shaft 310 and the slider 312 to move synchronously through the first tooth plate 39, thereby causing the slider 312 to slide inside the built-in slide groove 317, and the movement of the slider 312 pulls the counterweight ball 314 upward through the pull rope 313;

[0060] During this process, due to the action of the first spring 320, the third tooth plate 324 has a downward force applied, and the positioning block 325 is inserted into the top slot 318 at the corresponding position, so that the rotation radius does not change during the rotation of the L-shaped support rod 21. As the first rectangular frame 24 drives the L-shaped support rod 21 to rotate synchronously, the second tooth plate 321 is driven to rotate synchronously. When the top of the second tooth plate 321 fits with the bottom surface of the protrusion 38, the second tooth plate 321 rotates under the action of the inclination of the bottom surface of the protrusion 38, the second tooth plate 321 moves downward as the second tooth plate 321 rotates. The movement of the second tooth plate 321 drives the second gear 322 to rotate, thereby driving the third tooth plate 324 to move upward. In the process of moving upward, the third tooth plate 324 squeezes the first spring 320, and after the positioning block 325 slides out of the top slot 318, the counterweight ball 3 The pull rope 313 drives the L-shaped support rod 21 to slide on the surface of the slider 312 under the gravity of the L-shaped support rod 21, until the second tooth plate 321 slides out from the bottom surface of the protrusion 38, and the third tooth plate 324 moves downward under the elastic potential energy of the first spring 320, thereby driving the positioning block 325 to be inserted into the built-in slide groove 317 at the corresponding position, so as to fix the position of the L-shaped support rod 21 after moving, which is conducive to making the slider 312 slide inside the L-shaped support rod 21 during the process of the L-shaped support rod 21 rotating one circle. The movement of the slider 312 pulls the counterweight ball 314 to move through the pull rope 313, thereby realizing the force storage process of the movement of the L-shaped support rod 21. When the L-shaped support rod 21 rotates one circle, the L-shaped support rod 21 slides inside the first rectangular frame 24, thereby automatically changing the rotation radius of the L-shaped support rod 21, realizing automatic adjustment of the range of ground surveying and mapping, and improving the use effect of the surveying and mapping equipment;

[0061] When the paper on the surface of the paper roll 26 is completely wound and the paper roll 26 and the winding roller 220 need to be replaced, the internal thread ring 213 is rotated, and the internal thread ring 213 is removed from the surface of the external thread sleeve 23 under the action of the thread, and the paper roll 26 can slide out from the surface of the external thread sleeve 23 under the action of gravity. At this time, an upward force is applied to the first hexagonal rod 28 and the internal sleeve 29, so that the first hexagonal rod 28 and the internal sleeve 29 slide out from the inside of the first hexagonal groove 27 and the first circular groove 210 respectively. When the internal sleeve 29 and the internal sleeve 29 are moved to a suitable position, the paper roll 26 can be taken out from the bottom of the external threaded sleeve 23. At this time, a new paper roll 26 is replaced, and the first hexagonal rod 28 is inserted into the first hexagonal groove 27, and the internal sleeve 29 is inserted into the first circular groove 210. By sleeve-mounting the paper roll 26 on the external threaded sleeve 23, and inserting the rectangular inserting strip 212 into the rectangular slot 211, and rotating the internal threaded ring 213 on the external threaded sleeve 23, the internal threaded ring 213 is screwed on the external threaded sleeve 23. The groove and the inner thread ring 213 cooperate to fix the position of the replaced paper roll 26. When the winding roller 220 is replaced, the L-shaped plug plate 219 is pulled upward. When the L-shaped plug plate 219 slides to a suitable height inside the second rectangular frame 215, the winding roller 220 can be operated so that the two ends of the second hexagonal rod 221 are respectively taken out from the second hexagonal groove 224 and the third hexagonal groove 225, thereby facilitating the replacement of the winding roller 220. The replaced winding roller 220 allows the second hexagonal rod 221 to be inserted into the Inside the third hexagonal groove 225, operate the L-shaped plug plate 219 to allow the second hexagonal rod 221 to be inserted into the second hexagonal groove 224, so that the winding roller 220 can be driven to rotate when the first motor 214 is running, and the hexagonal joint 227 can slide inside the fourth hexagonal groove 226, avoiding the problem of damage to the first motor 214 caused by the up and down floating of the lower circular shaft 217 due to the gravity of the winding roller 220, which is conducive to facilitating the replacement of the paper roll 26 and the winding roller 220, thereby improving the ease of use of the surveying and mapping equipment.
