[0002] In industrial and civil buildings, in order to understand the settlement of buildings and promptly discover settlement phenomena that are unfavorable to buildings so as to take measures to ensure the safe use of buildings and provide data for future reasonable designs, settlement observations must be carried out during the construction process and after the buildings are put into production. The device used for settlement observations is called a settlement observation device.

[0003] The patent with publication number CN202023149983.5 proposes a building settlement or deformation observation device with a simple structure and easy operation. When measurement is not needed, the telescopic seat can be retracted into the telescopic cavity through the clamping device, the clamping slot and the clamping seat, thereby avoiding the problem of the observation device being exposed outside the building and causing injuries to pedestrians, eliminating safety hazards. At the same time, the self-designed measuring scale makes detection more convenient and simple, and has high practicality.

[0004] However, although the above patent can retract the observation device into the building to avoid pedestrian injuries, in order to facilitate pulling out the observation device, the push rod of its clamping device is still extended to the outside, which still poses a safety hazard. Therefore, a new stable measuring device for building settlement and deformation detection is proposed. Utility Model Content

A baffle 3 is fixed to one end of the telescopic cylinder 6, and the baffle 3 is located outside the fixed cylinder 1. A shell 14 is embedded between the baffle 3 and the telescopic cylinder 6. A pressing rod 4 and a pull rod 5 are arranged inside the shell 14. One end of the pressing rod 4 and the pull rod 5 pass through the baffle 3 and are located in the same plane as the baffle 3. A spring 16 is fixed between one end of the pressing rod 4 and the shell 14, and a linkage component is arranged between the pressing rod 4 and the pull rod 5. When the pressing rod 4 is pressed, the pull rod 5 extends out under the action of the linkage component.

[0028] The linkage assembly includes a gear 17, a first bar tooth 18 and a second bar tooth 19. The gear 17 is located between the pull rod 5 and the pressing rod 4, and the gear 17 is rotatably connected to the inner wall of the shell 14. The first bar tooth 18 is located on the surface of the pressing rod 4, and the second bar tooth 19 is located on the surface of the pull rod 5. The gear 17 is meshed with the first bar tooth 18 and the second bar tooth 19 respectively.

[0029] A stopper 15 is fixed to the inner wall of the shell 14, and the stopper 15 is slidably connected to the pull rod 5. A fixed block is connected to one end of the pull rod 5 located inside the shell 14. When the stopper 15 contacts the fixed block, it plays a role of limiting to prevent the pull rod 5 from being pulled off. The pull rod 5 is arranged in an L-shape, which is convenient for pulling the L-shaped end to bring out the telescopic cylinder 6.
