The outer walls of both ends of the steel base 2 are fixedly provided with a second connecting seat 12. A locking rod 13 movably passes through the outer side of each of the two second connecting seats 12. A stop block 14 is fixedly provided on the outer wall of each locking rod 13. A locking spring 15 is sleeved on the outer wall of the locking rod 13, located between the second connecting seat 12 and the stop block 14. A toggle button 16 is fixedly provided at one end of the locking rod 13. The outer side of the toggle button 16 is provided with rough texture to increase the friction between the hand and the toggle button 16. When locking the connection between the concrete base 1 and the steel base 2, and between the steel base 2 and the first guide rod 3, the locking rod 13 can be pulled first. After the steel base 2 is connected to the concrete base 1 and the first guide rod 3, the locking rod 13 is released. At this time, the locking spring 15 presses the stop block 14. The pressed stop block 14 drives the locking rod 13 to approach the first connecting seat 10 and engage with the locking hole 11 on the surface of the first connecting seat 10, thereby completing the locking between the concrete base 1 and the steel base 2, and between the steel base 2 and the first guide rod 3.

Then, the steel base 2 is rotated counterclockwise so that the locking block 8 engages with the end of the slot 9. Then, the locking rod 13 is released. At this time, the locking spring 15 presses the stop block 14. The pressed stop block 14 drives the locking rod 13 closer to the first connecting seat 10 and... The locking hole 11 on the surface of the first connecting seat 10 is inserted to complete the locking between the concrete base 1 and the steel base 2, and between the steel base 2 and the first guide rod 3. Through the locking connection of the two sets of locking components, the stability of the connection and fixation between the concrete base 1, the steel base 2, and the first guide rod 3 can be further improved. The structure can quickly and conveniently realize the fixed connection and disassembly between the concrete base 1, the steel base 2, and the first guide rod 3, which facilitates the installation, use, disassembly, and recycling efficiency of the entire settlement monitoring device and improves the practicality of the device. The above is the working principle of the surcharge preloading laser settlement monitoring device.
