The outer wall of the turntable 43 is provided with a U-shaped piece 433, and the U-shaped piece 433 is rotatably connected to the toggle rod 4331 on the side away from the first turntable 42. The toggle rod 4331 is provided with a protrusion 4332 at the end away from the U-shaped piece 433. The lower end of the U-shaped piece 433 passes through and is rotatably connected to the second turntable 44. The middle end of the second turntable 44 is fixedly connected to the first connecting rod 441. The first connecting rod 441 is rotatably connected to the second connecting rod 442 at the end away from the second turntable 44. The end away from the No. 1 connecting rod 441 is rotatably connected to one side of the sliding plate 33, and the two ends of the No. 2 rotating rod 44 are fixedly connected to the No. 1 ratchet gear 443. The outer ratchet gear groove of the No. 1 ratchet gear 443 fits 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 with an upper ratchet bar 452 and a lower ratchet bar 454, and the No. 1 ratchet gear 443 is meshed with the upper ratchet bar 452.

[0023] like Figure 7As shown, the upper ratchet bar 452 and the lower ratchet bar 454 are fixedly connected by a column 453, a vertical rod 456 is fixedly connected to one side of the fixed shell 451, and the vertical rod 456 is rotatably connected to the second ratchet gear 46 at the end away from the fixed shell 451, and the second ratchet gear 46 is fixedly connected to the action roller 13, and the outer wall of the fixed shell 451 is fixedly connected to the servo motor 4511, and the output end of the servo motor 4511 is fixedly connected to the third connecting rod 4512, and the third connecting rod 4512 is rotatably connected to the end away from the servo motor 4511. It is connected to a Y-shaped rod 4513, the middle end of the Y-shaped rod 4513 is rotatably connected to the bottom of the upper ratchet bar 452, the Y-shaped rod 4513 is rotatably connected to the fourth connecting rod 4514 at the end away from the third connecting rod 4512, and the fourth connecting rod 4514 is rotatably connected to the inner wall of the fixed shell 451 at the end away from the Y-shaped rod 4513, wherein: the third connecting rod 4512 is fixedly connected to the third rotating rod 455 on one side of the connection between the output end of the servo motor 4511 and the third connecting rod 4512, and the third rotating rod 455 passes through the fixed shell 451.

[0024] It can be seen from this that when workers transport or use land management equipment, Figure 1-Figure 5 As shown, during use, the staff grasps the handle 11 to push the device. At this time, the detection head 142 is used to detect and plan the land while the device is moving. During this process, if special terrain blocks the measurement, the telescopic component 3 and the protective device 4 are used together to move the detection head 142 up and down to achieve a change in the detection effect. Among them: the staff turns on the switch of the protection device 4, and the No. 1 rotating rod 411 rotates under the drive of the dual-axis motor 41. At the same time, the No. 1 rotating rod 411 drives the No. 1 turntable 42 to rotate. It should be noted that the positions of the vertical column 421 and the fixed column 422 are both at the end positions of the bar hole 431 and the arch hole 432, that is, the No. 2 turntable 43 and the No. 1 turntable 42 are not at the same center position. At this time, the No. 1 turntable 42 drives the No. 2 turntable 43 to rotate eccentrically, and at this time, the No. 2 turntable 43 will push back and forth during the eccentric rotation. The movable U-shaped member 433 rotates back and forth left and right with the second rotating rod 44 as the center. At the same time, the U-shaped member 433 also drives the toggle rod 4331 to move left and right. The toggle rod 4331 at the end away from the connection with the U-shaped member 433 slides along the outer wall of the first ratchet gear 443 due to the influence of gravity. When the toggle rod 4331 moves to the right again after completing the leftward movement, the protrusion 4332 fits into the ratchet gear groove of the first ratchet gear 443. At this time, the protrusion 4332 pushes the first ratchet gear 443 to rotate a certain angle. It should be noted that the reciprocating rotation amplitude of the U-shaped member 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, the rotation amplitude of the U-shaped member 433 is smaller, and the rotation angle of the driven first ratchet gear 443 is also smaller. This can adjust the extension and contraction amplitude of the detection head 142 to achieve a more precise effect. When the second connecting rod 442 pushes the sliding plate 33, the sliding plate 33 will go deeper into the inner side of the placement table 14 and use the inclined surface 331 on one side of the sliding plate 33 to squeeze the slope part of the bottom of the bevel column 32, pushing the bevel column 32, the rotating wheel 31 and the detection head 142 upward, thereby changing the detection effect of the detection head 142. When the sliding plate 33 slides gradually to the deepest position in the placement table 14, one side of the bevel 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 detection head 142 is at the highest point it can extend. It should be noted that, if the detection head 142 needs to be protected in adverse weather such as rain, as described 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 beveled column 32, causing the beveled column 32 to slide downward to the placement groove 1412. At this time, the detection head 142 is completely received in the cylindrical groove 141. When the device is pushed onto a bumpy road, it is necessary to ensure the stability of the detection head 142. Figure 4-Figure 6 As shown, when driving on a bumpy road section with a large slope, the staff turns on the switch of the reciprocating assembly 45, and the third connecting rod 4512 rotates under the drive of the servo motor 4511, as shown in FIG. Figure 7As shown, when the third connecting rod 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 bar 452 and the lower ratchet bar 454 downward by a certain distance. When the lower ratchet bar 454 moves down to engage with the second ratchet gear 46, the rotating action roller 13 will drive the second ratchet gear 46 to rotate, pushing the lower ratchet bar 454 in the opposite direction, so that the rotation of the servo motor 4511 is resisted. The third connecting rod 4512 is driven to reverse, that is, rotate counterclockwise. Similarly, the reversed third connecting rod 4512 also drives the upper ratchet bar 452 to engage with the first ratchet gear 443, and again causes the servo motor 4511 to reverse after being subjected to resistance. This cycle repeats. When the device travels on a bumpy road section with a large slope, the resistance of the lower ratchet bar 454 to the second ratchet gear 46 is used to achieve intermittent buffering on the bumpy road section with a slope, thereby achieving stability on the bumpy road section. It should be noted that the initial positions of the upper ratchet bar 452 and the lower ratchet bar 454 are not engaged with the first ratchet gear 443 and the second ratchet gear 46. When the reciprocating assembly 45 is switched to operate, the dual-axis motor 41 no longer operates.
