[0014] 1. The total station hanging mechanical high-precision coaxial prism device is provided with an adjustment bracket component group and a quick-disassembly component group. At present, the total station hanging bidirectional prism generally uses a small prism. Due to the limitation of machining accuracy, the two small prisms hanging below cannot be vertically on the same axis. The data fluctuates greatly during measurement, and the monitoring requirements of high accuracy and strict control value cannot be met. In the corresponding designed adjustment bracket component group, the position between the upper and lower small prism bodies can be calibrated by adjusting the bracket component group structure. When the position between the small prism body and the adjustment bracket component group needs to be calibrated and adjusted , by loosening the pressure cylinder, the pressure cylinder is released from contact with the lower tank shell, and then the small prism body and the quick-release component group at the lower position can be controlled to move left and right.

The design of this adjustment bracket component group can adjust the position of the small prism body at the lower position, so that the upper and lower small prism bodies can be on the same vertical axis, thereby ensuring the stability of the data during measurement and achieving the monitoring requirements of high precision and strict control value;

[0015] 2. The mechanical high-precision coaxial prism device hanging below the total station is provided with an adjustment bracket component group and a quick-release component group. The current installation of the bidirectional prism hanging below the total station is all through a threaded connection method, which is time-consuming during installation and disassembly, and is not conducive to quick installation and disassembly. In the corresponding designed quick-release component group, by pinching the two handle rods to get close to each other, the card block can be driven to slide in the sleeve shell body. At this time, the spring part accumulates force and contracts, and the card block is released from the contact with the card slot of the plug-in. Then the small prism body can be removed from the quick-release component group. During installation, the plug-in on the small prism body is directly controlled to be inserted into the slot in the sleeve shell body. During the insertion process, the plug-in will push the card block open to make the spring part accumulate force and contract. Then, when the plug-in is fully inserted into the sleeve shell body, the spring part releases the accumulated force to push the card block into the card slot of the plug-in. The plug-in is locked in position by the card block, thereby completing the connection between the small prism body and the adjustment bracket component group. The design of this quick-release component group improves the installation and disassembly speed of the small prism body, thereby improving usability. BRIEF DESCRIPTION OF THE DRAWINGS
