A first rotating rod 411 is fixedly connected to the output end of the dual-axis motor 41. A first turntable 42 is fixedly connected to the end of the first rotating rod 411 furthest from the dual-axis motor 41. A vertical column 421 is fixedly connected to the center of the first turntable 42. Triangular grooves 4211 are formed on both sides of the vertical column 421. Fixed columns 422 are fixedly connected to the periphery of the vertical column 421. Turntable 42 has a second turntable 43 on the side away from the first turntable 411. A strip-shaped hole 431 is formed along the diameter line of the second turntable 43. Multiple triangular buckles 4311 are fixedly connected to the inner wall of the strip-shaped hole 431. A vertical post 421 is slidably connected within the strip-shaped hole 431, and the triangular buckles 4311 fit into the triangular grooves 4211. Arched holes 432 are formed on both sides of the strip-shaped hole 431 on the second turntable 43. Fixed posts 422 are slidably connected within the arched holes 432. A U-shaped component 433 is fitted onto the outer wall of the turntable 43. A lever 4331 is rotatably connected to the U-shaped component 433 on the side away from the first turntable 42. A protrusion 4332 is provided at the end of the lever 4331 away from the U-shaped component 433. A second rotating rod 44 is rotatably connected to the lower end of the U-shaped component 433. A first connecting rod 441 is fixedly connected to the middle end of the second rotating rod 44. A second connecting rod 442 is rotatably connected to the end of the first connecting rod 441 away from the second rotating rod 44. The end of the first connecting rod 441 is rotatably connected to the side of the sliding plate 33. The two ends of the second rotating rod 44 are fixedly connected to the first ratchet 443. The outer ratchet groove of the first ratchet 443 is engaged with the protrusion 4332. The reciprocating assembly 45 includes a fixed shell 451, which is fixedly connected to the outer wall of the inner interlayer 2. The inner side of the fixed shell 451 is slidably connected to the upper ratchet rack 452 and the lower ratchet rack 454. The first ratchet 443 is meshed with the upper ratchet rack 452.

[0040] like Figure 7As shown, the upper ratchet rack 452 and the lower ratchet rack 454 are fixedly connected by a column 453. A vertical rod 456 is fixedly connected to one side of the fixed housing 451. A second ratchet gear 46 is rotatably connected to the end of the vertical rod 456 away from the fixed housing 451. The second ratchet gear 46 is fixedly connected to the moving roller 13. A servo motor 4511 is fixedly connected to the outer wall of the fixed housing 451. A third connecting rod 4512 is fixedly connected to the output end of the servo motor 4511. The third connecting rod 4512 rotates at the end away from the servo motor 4511. A Y-shaped rod 4513 is connected, with its middle end rotatably connected to the bottom of the upper ratchet rack 452. A fourth connecting rod 4514 is rotatably connected to the end of the Y-shaped rod 4513 away from the third connecting rod 4512. The fourth connecting rod 4514 is rotatably connected to the inner wall of the fixed housing 451 at the end away from the Y-shaped rod 4513. A third rotating rod 455 is fixedly connected to the side of the connection between the output end of the servo motor 4511 and the third connecting rod 4512. The third rotating rod 455 passes through the fixed housing 451.

[0041] Therefore, it can be concluded that when staff transport or use land management equipment, if... Figures 1-5 As shown, during use, the staff holds the handle 11 and pushes the device. While the device is moving, the probe 142 is used to measure and plan the land. If special terrain obstructs the measurement, the telescopic component 3 and the protective device 4 work together to move the probe 142 up and down to change the detection effect.

[0042] The process involves the operator activating the safety device 4 switch. Driven by the dual-axis motor 41, the first rotating rod 411 rotates. Simultaneously, the first rotating rod 411 drives the first turntable 42 to rotate. It should be noted that the vertical column 421 and the fixed column 422 are both located at the ends of the strip hole 431 and the arched hole 432, meaning the second turntable 43 and the first turntable 42 are not at the same center. At this time, the first turntable 42 drives the second turntable 43 to rotate eccentrically. During this eccentric rotation, the second turntable 43 pushes back and forth. The moving U-shaped part 433 rotates back and forth about the second rotating rod 44 as the center. At the same time, the U-shaped part 433 will also drive the actuating rod 4331 to move left and right together. The actuating rod 4331 will slide along the outer wall of the first ratchet 443 due to gravity at the end away from the U-shaped part 433. When the actuating rod 4331 moves to the right after moving to the left, the protrusion 4332 will engage with the ratchet groove of the first ratchet 443. At this time, the protrusion 4332 will push the first ratchet 443 to rotate a certain angle.

[0043] It should be noted that the reciprocating rotation amplitude of the U-shaped component 433 can be achieved by adjusting the position of the second turntable 43. When the second turntable 43 is closer to the center of the first turntable 42, that is, when the vertical column 421 is closer to the center of the second turntable 43, the rotation amplitude of the U-shaped component 433 is smaller, and the rotation angle of the first ratchet 443 driven by it is also smaller. This can adjust the extension and retraction amplitude of the probe head 142, making the effect more accurate.

[0044] At this time, the rotating ratchet 443 will drive the second rotating rod 44 to rotate together, and the second rotating rod 44 will drive the first connecting rod 441 to pull or push the second connecting rod 442, thereby realizing the second connecting rod 442 to pull or push the sliding plate 33. When the second connecting rod 442 pushes the sliding plate 33, the sliding plate 33 will go deeper into the placement platform 14, and use the inclined surface 331 on one side of the sliding plate 33 to squeeze the slope part at the bottom of the inclined column 32, pushing the inclined column 32, the rotating wheel 31 and the probe head 142 upward, thereby changing the detection effect of the probe head 142. When the sliding plate 33 gradually slides to the deepest position in the placement platform 14, one side of the inclined column 32 will contact the touch sensor 34 on the top of the sliding plate 33. At this time, the touch sensor 34 will transmit information to the dual-axis motor 41, causing the dual-axis motor 41 to stop operating. At this time, the probe head 142 is at its highest point of extension.

[0045] It should be noted that if adverse weather conditions such as rain occur and the probe head 142 needs to be protected, as mentioned above, the second connecting rod 442 pulls the sliding plate 33 to the rightmost position. At this time, the inclined surface 331 disengages from the inclined column 32, causing the inclined column 32 to slide down to the placement groove 1412. At this time, the probe head 142 is completely retracted into the cylindrical groove 141.

[0046] When the device is pushed onto a bumpy road section, it is necessary to ensure the stability of the probe head 142, such as Figures 4-6 As shown, when driving on a steep and bumpy section of road, the operator turns on the switch of the reciprocating assembly 45. Driven by the servo motor 4511, the third connecting rod 4512 rotates, as... Figure 7As shown, when the third linkage 4512 rotates clockwise to the lower position, it will also drive the Y-shaped rod 4513 to rotate together. At this time, the clockwise rotation of the Y-shaped rod 4513 will pull the upper ratchet 452 and the lower ratchet 454 to move down a certain distance. When the lower ratchet 454 moves down to mesh with the second ratchet gear 46, the rotating moving roller 13 will drive the second ratchet gear 46 to rotate, which will push the lower ratchet 454 in the opposite direction, causing the servo motor 4511 to encounter resistance. This causes the third connecting rod 4512 to reverse, that is, to rotate counterclockwise. Similarly, the reversed third connecting rod 4512 will also cause the upper ratchet 452 to mesh with the first ratchet 443, and cause the servo motor 4511 to reverse again after encountering resistance. This process is repeated. When the equipment travels to a bumpy section with a large slope, the resistance of the lower ratchet 454 to the second ratchet 46 is used to achieve intermittent buffering on the bumpy section with a slope, thus achieving stability on the bumpy section with a slope.

[0047] It should be noted that the initial positions of the upper ratchet 452 and the lower ratchet 454 are not engaged with the first ratchet 443 and the second ratchet 46. When switching to the reciprocating assembly 45, the dual-axis motor 41 no longer runs.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of the present invention.
