[0003] According to the description in the USB interface structure of a three-proof Internet of Things device disclosed on the patent network (authorization announcement number: CN212908302 U), "A USB interface structure of a three-proof Internet of Things device belongs to the technical field of USB interface structures. The USB interface structure of this three-proof Internet of Things device includes a floor sweeping robot main body. A USB insertion end is arranged on the surface of the floor sweeping robot main body. A plug is fixedly connected inside the USB insertion end. A connecting rope is fixedly connected to the surface of the floor sweeping robot main body near the USB insertion end. One end of the connecting rope is fixedly connected to a closing cover, and a rubber layer is fixedly connected to the surface of the closing cover. In the USB interface structure of this three-proof Internet of Things device, through the settings of the connecting rope, the closing cover and the rubber layer, when in use, open the closing cover, the connecting rope can prevent the closing cover from falling off, connect the USB joint end inside the USB insertion end for charging and data transmission, and after use, cover the USB insertion end with the closing cover, and the rubber layer can effectively prevent water ingress, avoid the plug from getting damp, and extend the service life."

[0004] Based on the above content, the inventor believes that the following defects exist: During the use of the USB interface structure of this three-proof Internet of Things device, when the USB insertion end is covered with the closing cover, the rubber layer can effectively prevent water ingress, avoid the plug from getting damp, and extend the service life. However, when the USB interface structure is not connected to the USB plug, it lacks the function of dust prevention, resulting in dust possibly entering the inside of the USB interface, and then the dust affecting the components inside the USB interface, making the data transmission between the USB interface and the USB plug unstable.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: 1.

And the round block will also drive the first magnet to move in a circular motion along the center through the connecting shaft and the round sleeve, so that the first magnet and the second magnet are disengaged from adsorption. When the top of the stopper corresponds to the bottom of the dust-proof plate after rotation, at this time, the third magnet and the first magnet will adsorb each other to limit the stopper, making it impossible to move easily.

[0029] Further, the clamping shaft 36 penetrates through the top of the connection frame 6. A shaft hole is opened at the top of the USB plug 5. The clamping shaft 36 is inserted into the inner wall of the opened shaft hole. Through the mutual cooperation of the clamping shaft 36 and the shaft hole, the USB plug 5 cannot move easily, enhancing the stability during the data transmission process.

[0030] Embodiment 3 Refer toFigures 1 to 8 On the basis of Embodiment 1 and Embodiment 2, it is further obtained that the connecting mechanism 4 includes a fixing block 41.
