[0045] But when the distance measuring wheel 5 needs to be locked, the operator pulls the handle 31, and the brake force is transmitted to the brake connecting rod 33 through the flexible brake wire 32, the brake connecting rod 33 rotates around the hinge point of the brake connecting rod 33 and the connecting plate 34 after being subjected to the brake force, and the brake force is transmitted to the brake pad 35, the brake pad 35 is tightly attached to the distance measuring wheel 5 after being subjected to the brake force, and the rotation of the distance measuring wheel 5 is prevented by friction to achieve the locking function, when the locking is to be released, the operator only needs to release the handle 31.

[0046] During the measurement process, the mud scraping plate 72 can remove the mud and sundries adhered to the distance measuring wheel 5, and the cleanliness and measurement accuracy of the distance measuring wheel 5 are maintained.

[0047] In summary, the land planning and measuring device can realize accurate measurement through the distance measuring wheel 5 and the digital counter 4, provide comfortable operation experience through the telescopic push rod 2 and the handle 1, improve the moving stability and efficiency through the auxiliary moving mechanism 6, lock the position of the distance measuring wheel 5 through the locking mechanism 3, and keep the distance measuring wheel 5 clean through the mud scraping mechanism 7.
