[0002] High-precision measurement is of great significance to engineering construction, resource exploration, urban planning and the like. At present, as a commonly used high-precision surveying and mapping equipment, RTK (Real-Time Kinematic) surveying and mapping instrument is widely applied because it can obtain centimeter-level positioning data in real time. To facilitate measurement operation, the RTK surveying and mapping instrument is usually mounted on a rod body, and a measurement personnel can hold the rod body to adjust the position of the surveying and mapping instrument, and when necessary, the rod body needs to be inserted into soil to fix the surveying and mapping instrument, so as to ensure the stability of measurement data.

[0003] However, the rod body structure of the existing surveying and mapping instrument is relatively simple, and only serves as a supporting component for bearing the surveying and mapping instrument. In actual use, when the rod body needs to be inserted into soil, the measurement personnel often needs to exert a lot of physical effort to press down the rod body due to the lack of effective auxiliary insertion structure, especially in soil environment with hard texture or high viscosity, the insertion operation is extremely difficult; and after completing measurement, it is also inconvenient to pull out the rod body from soil, because the soil has large adsorption and friction force on the rod body, and the rod body is simply pulled out by human force, which is laborious to operate. The difficulty in insertion and pulling out significantly reduces the work efficiency of topographic surveying and mapping, increases the labor intensity of measurement personnel, and is difficult to meet the demand for high efficiency and convenience of modern surveying and mapping work.

[0016] Further, the sleeve wall of the sleeve is threadedly connected with a jackscrew, the jackscrew penetrates the sleeve wall, and the screwing end of the jackscrew can abut against the outer wall of the rod body.

[0017] Further, the rod body is provided with a plurality of positioning holes for the jackscrew to enter.

[0018] Further, the outer wall of the sleeve is fixedly provided with a handle.

[0019] (Three) beneficial effects

[0020] Compared with the prior art, the utility model provides a surveying and mapping device suitable for land survey of multiple terrains, and has the following beneficial effects:

[0021] The surveying and mapping device suitable for land survey of multiple terrains is provided with the sleeve and the blocking block, in the process of inserting the rod body into the soil, the surveying personnel only need to drive the sleeve downward, so that the sleeve impacts the first blocking block at the bottom, the impact force generated by the falling of the sleeve can assist the rod body to be quickly and labor-savingly inserted into the soil, the difficulty of human pressure is greatly reduced, and the device is especially suitable for the soil environment with hard texture or strong viscosity. When the rod body is pulled out, the sleeve is lifted upward to impact the second blocking block at the top, and the reaction force of the sleeve can easily overcome the adsorption force and friction force of the soil on the rod body. The complex insertion and pulling-out process is converted into the simple pushing and pulling action of the sleeve, the convenience and efficiency of the surveying and mapping operation are remarkably improved, the physical consumption of the surveying personnel is greatly reduced, the surveying and mapping working time is effectively shortened, and the operation is more labor-saving, convenient and efficient.
