[0015] Working principle: when the device needs to be used, first pull the handle to drive the rotating shaft to rotate inside the fixed plate; when the rotating shaft rotates inside the fixed plate driven by the handle, the rotating shaft will drive the rotating rod to rotate; when the rotating rod rotates driven by the rotating shaft, the rotating rod will drive the first transmission block to rotate synchronously; when the first transmission block rotates driven by the rotating rod, the rotating rod will drive the first push rod to slide inside the cover plate; when the first push rod slides driven by the first transmission block, the first push rod will drive the first spring to undergo elastic deformation; at the same time, the card block slides inside the cover plate driven by the first push rod; at this time, the card block disengages from the limiting groove and passes through the first groove. The handle is pulled through the groove to make it slide on the surface of the gas meter body, and then the handle drives the slider to slide in the third groove, and then the positioning groove comes to the clamping block as the handle slides. At this time, the handle is released, and the clamping block enters the positioning groove to fix the handle, thereby finally achieving the purpose of storing the handle at any time, so that it is convenient for the user to carry during installation and to store it after the installation is completed; the handle is pressed to separate the clamping block from the handle, and then the handle is pulled to slide along the inner wall of the shell.

[0017] 2. The present invention receives external impact through the first baffle plate and drives the second spring to compress. Then the damping expands and contracts with the sliding of the first baffle plate. When the first baffle plate moves, it drives the fixed block to move synchronously. Then, driven by the fixed block, the first rotating column moves left and right. When the first rotating column moves left and right, it drives the rotating plate to rotate. When the rotating plate rotates, it drives the second rotating column to move up and down, thereby finally achieving the purpose of alleviating impact, thereby preventing the gas meter body from being damaged by external impact.

[0018] 3.
