[0018] The application provides a device for adjusting and shrinking a building fire-fighting emergency fire-fighting cabinet conveniently and moving, which has the following beneficial effects:

[0019] 1. The building's fire emergency cabinet has an adjustable and retractable device for easy movement. In the event of a fire, manually pulling the handle moves the vertical plate, which in turn moves the cabinet body, which in turn moves the loading box. The loading box then moves the limiting plate, which contains multiple fire extinguishers. This allows for the rapid transport of multiple fire extinguishers to the fire location. Pulling the handle opens the protective door, allowing the fire extinguishers to be removed from the limiting plate and used for firefighting, saving physical effort.

[0020] 2. The building's fire emergency cabinet features an adjustable, retractable, and easily movable device. When the cabinet is pulled, rollers rotate. Rubber rings are fitted on the outer sides of the rollers to increase friction with the ground, preventing slippage. These rollers drive a rotating shaft, which in turn drives a first gear. This first gear, in turn, drives a driven gear, which in turn drives a second gear. This second gear, in turn, drives a rotating rod, which in turn drives a third bevel gear. The third bevel gear, when rotating... The reciprocating screw rotates, causing the moving seat to move up and down. As the moving seat moves, it moves the fixed rod, which in turn moves the fixed frame. As the fixed frame moves, it moves the connecting rod, which in turn moves the upper and lower gears. The upper and lower gears then move the support plate, which in turn moves the positioning shaft. This positioning shaft then moves the mounting plate, which in turn moves the bracket, which in turn moves the loading box and the limiting plate. This movement causes multiple fire extinguishers to move up and down, shaking them and preventing the dry powder inside the fire extinguishers from settling.

[0021] 3. The building's fire emergency cabinet features an adjustable, retractable, and easily movable device. When the reciprocating screw rotates, it limits the movement of the limiting block via a limiting groove, causing the limiting block to rotate. This rotation of the limiting block drives the first bevel gear to rotate, which in turn drives the second bevel gear to rotate. The second bevel gear's rotation then drives the connecting rod to rotate, causing the connecting rod to rotate the upper gear around the connecting rod. The upper gear's rotation then drives the lower gear to rotate, which in turn moves the guide rod, causing the guide rod to rotate and thus move the movable frame. The mobile frame moves up and down along the sliding rod, which limits the movement of the mobile frame and the support plate. The support plate, during movement, causes the positioning shaft to swing back and forth, moving up, down, left, and right. This, in turn, causes the mounting plate to swing back and forth, thus moving the support frame, which in turn moves the loading box and the limiting plate. This allows the fire extinguisher to be shaken during its movement to the fire scene, ensuring it is prepared in advance and preventing the dry powder or foam filling material from settling. This improves work efficiency, allowing for direct use upon arrival at the fire scene and saving valuable rescue time. Attached Figure Description
