[0002] Geological minerals refer to minerals or rock resources that are formed through geological mineralization and naturally occur in the earth's crust or buried on the surface. Geological minerals play a vital role in the development of human society and are widely used. They can be used as the source of industrial raw materials and building materials. They are also an important driving force for the advancement of science and technology industries. Therefore, the exploration of geological minerals is of great significance. In the process of geological mineral exploration, corresponding measuring devices are needed to measure the size of geological cracks. As shown in announcement number CN117553651A, a geological crack measuring device is disclosed. Due to the uneven outer surface of the rock and soil body during measurement, gaps are easily generated during measurement, which affects the measurement accuracy. The following scheme is proposed, including a fixed base plate, the outer walls of the two fixed base plates are fixedly connected with connecting parts, and the inner walls of one side of the two connecting parts are fixedly connected with two movable connecting rods, the outer walls of the four movable connecting rods are respectively provided with two hollow connecting rods, and the outer walls of the two hollow connecting rods are fixedly connected with the same handle, and a fitting measurement component is provided between the two fixed base plates. The geological crack measuring device disclosed in the present invention has the function of improving the contact effect between the device and the outer surface of the rock and soil body. When in use, the elastic rod body can be adjusted according to the unevenness of the rock and soil body to reduce the gap between the device and the outer surface of the rock and soil body, thereby improving the measurement accuracy of the device and increasing the use effect; For example, announcement number CN208751423U discloses a geological disaster crack measuring device, which relates to the technical field of crack measuring tools, specifically a geological disaster crack measuring device, including a crack measuring device and a fixing device, wherein the crack measuring device includes a telescopic rod, a scale, a first sleeve, a first moving block, a first measuring bar, a second sleeve, a second moving block, and a second measuring bar, and a scale is provided on the surface of one side of the telescopic rod. The geological disaster crack measuring device installs the first sleeve and the second sleeve on one side of the telescopic rod. Such a design allows the two sleeves to slide back and forth on the telescopic rod, and the first measuring bar and the second measuring bar are respectively provided at the bottom of the first sleeve and the second sleeve. Such a design allows the user to drive the first measuring bar and the second measuring bar to press against the two sides of the crack by sliding the sleeve during measurement. Such a measurement method greatly improves the accuracy of the data measured by the measuring device; However, the existing geological fracture measurement devices for geological and mineral exploration still have the following shortcomings: 1. The existing geological fracture measurement device for geological and mineral exploration has a large overall volume, and the use of the measurement components is relatively complicated and cumbersome. The production and use costs are high, which is not conducive to popularization and use. When used for outdoor measurement, it is inconvenient to carry and move; 2. In the existing geological fracture measurement device for geological and mineral exploration, the height of the measuring long plate is usually fixed during measurement, but some fractures have different shapes and depths, which makes it inconvenient to adjust the height of the measuring long plate according to actual measurement needs; 3. In the existing geological fracture measuring device used for geological and mineral exploration, during measurement, the measuring long plate is attached to the side wall of the fracture, and there is a lack of a limit assembly for fixing the measuring long plate. The error generated during the measurement process is large, and it is not convenient to observe and read the measurement data intuitively.
