[0038] Working principle: The mounting plate 3 can be fixed at the place where it needs to be installed through the mounting hole 33, and the skateboard 2 can be slid inside the mounting plate 3. By rotating the turntable 5, the rotating shaft 14 connected to it can be driven to rotate. The rotation of the rotating shaft 14 can drive the bevel gear 16 to rotate. The rotation of the bevel gear 16 not only changes the direction of transmission, but also effectively transmits power to the bevel gear 2 7. The bevel gear 2 7 is connected to the bevel gear 16 at right angles, and its rotation further transmits the rotational motion to the worm 8. As a spiral gear, the rotation of the worm 8 is closely matched with the worm wheel 9. The rotation of the worm 8 drives the worm wheel 9 to rotate. This cooperation not only has a high transmission ratio, but also has a good self-locking function to prevent the system from reverse motion when it is stationary. The rotation of the worm wheel 9 is further transmitted to the rotating shaft 2 10. The rotation of the rotating shaft 2 10 drives the rotating plate 11 and the connecting plate 12 connected to it to rotate. The rotation of the connecting plate 12 drives the moving plate 13 to perform linear motion. The moving plate 13 can be moved by To push the connecting block 14 to move, the movement of the connecting block 14 directly affects the movement of the fixing rod 15. The precise movement of the fixing rod 15 ultimately acts on the slide 2, firmly fixing the slide 2 to achieve a stable installation of the device housing 1. When equipment maintenance is needed, it is only necessary to rotate the turntable 5 in the opposite direction, and the entire transmission system will move in the opposite direction in turn. The fixing rod 15 will loosen the fixation of the slide 2 as the connecting block 14 moves in the opposite direction, so that the slide 2 can slide freely, and the device housing 1 can be quickly disassembled, which is convenient for internal maintenance and inspection. In order to protect the internal components from external vibration and mechanical shock, the spring 27 is used to enable the buckle 25 to rotate on the rotating shaft 3 24. Through cooperation with the stop block 26, when external vibration occurs, the buffer plate 16 can play a buffering role, effectively absorbing and weakening external impact, and reducing damage to internal components. This buffer design not only prevents internal components from being damaged by mechanical shock or vibration, but also significantly improves the reliability and service life of the entire device.
