[0003] Application No. 202222922252.2 discloses an area measuring device for land planning. Through a fixing mechanism, people can first select a tape measure of appropriate length according to the size of the land to be measured, and set it on the servo motor through the through hole, and then cover the top cover. When covering the top cover, first pinch the slide plate inward to compress the spring, and then close the top cover tightly so that the card hole on the card block corresponds to the card column on the slide plate. At this time, release the slide plate, and the slide plate will be squeezed to both sides under the action of the rebound force of the spring, so that under the guidance of the slide rod, the card column will be stuck in the card block. The top cover can be fixed on the upper part of the casing, so that the top cover can be fixed. When the scale of the measuring roll is blurred due to long-term use and needs to be replaced, people can pinch the slide plate inward to disengage the clamping column from the clamping hole, thereby releasing the restriction on the top cover, and then flip the top cover to replace the measuring tape roller, which is beneficial to actual use. At the same time, when the top cover is fixed, the positioning column on the top cover will be stuck into the positioning port on the measuring tape roller, which can provide a limit for the measuring tape roller during the process of retracting and releasing the measuring tape to prevent the measuring tape roller from shaking and affecting the work of retracting and releasing the measuring tape.

[0004] In the measurement structure of the above application, the length of the unfolded tape measure needs to be recognized by the human eye, which is prone to errors and cannot measure spatial angles, which has great limitations. Utility Model Content
