[0022] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 A first spring 7 is arranged on the outer side of the guide rod 6, one end of the first spring 7 is fixedly connected to the dustproof plate 3, and the other end of the first spring 7 is fixedly connected to the fixing seat 4. By designing the first spring 7, the force of the first spring 7 can act on the dustproof plate 3. A selection switch 10 is arranged at the front end of the shell 1 and on the right side of the interface 2. The top of the selection switch 10 contacts with a connecting seat 11, and the connecting seat 11 is fixedly connected to the shell 1. A limiting mechanism 9 is arranged on the selection switch 10.

[0023] See also Figure 1 , Figure 4 , Figure 5The limiting mechanism 9 includes a second spring 91, a second spring 91 is arranged inside the connecting seat 11, one end of the second spring 91 is fixedly connected to the slider 92, and the other end of the second spring 91 is fixedly connected to the connecting seat 11. By designing the second spring 91, the force of the second spring 91 can act on the slider 92, and the connecting seat 11 is internally slidably sleeved with a plurality of evenly distributed sliders 92, the bottom of the slider 92 is fixedly connected with a slide rod 93, the slide rod 93 is slidably connected to the connecting seat 11, and the bottom of the slide rod 93 is fixedly connected with a slide seat 94, the slide seat 94 is internally movably sleeved with a ball 95, the ball 95 is movably connected to the connecting seat 11, and the ball 95 is slidably connected to the selection switch 10. A groove 96 is provided inside the selection switch 10, and the ball 95 is slidably connected inside the groove 96. By designing the groove 96, the ball 95 can slide into the interior of the selection switch 10, and by designing the limiting mechanism 9, the selection switch 10 can be assisted in limiting.

[0024] Working principle: When in use, the dustproof plate 3 can be used to block the interface 2 when it is not in use, so as to block the interface 2 from dust and prevent dust from entering. When the interface 2 needs to be used, the pull rod 5 is pulled down, and the pull rod 5 drives the dustproof plate 3 to move down, and the dustproof plate 3 drives the guide rod 6 to slide along the fixed seat 4. The dustproof plate 3 will squeeze the first spring 7, so that the dustproof plate 3 moves down and separates from the interface 2, and then the network cable can be inserted into the interface 2 for connection and use. When the connection is completed, the dustproof plate 3 is slowly moved up and reset to make the dustproof plate 3 contact with the network cable. At this time, the first spring 7 is still in a compressed state. Under the elastic action of the first spring 7, an upward thrust will be given to the dustproof plate 3, so that the dustproof plate 3 is pressed against the network cable, which can support the lower part of the network cable, play an auxiliary limit role, and improve the connection stability between the network cable and the interface 2.

[0025] The insertion of the ball 95 and the groove 96 can play a certain limiting role on the selection switch 10, and can prevent the selection switch 10 from moving and affecting the use of the device due to accidental touch. When the selection switch 10 needs to be used, the selection switch 10 is pushed with a little force, and the selection switch 10 and the ball 95 slide relative to each other. The selection switch 10 will squeeze and push the ball 95 to move upward, and the ball 95 drives the slide seat 94 to move upward. The slide seat 94 will drive the slide bar 93 and the slider 92 to move upward. The slider 92 will squeeze the second spring 91 to separate the selection switch 10 from the ball 95. As the selection switch 10 moves, the contact between the selection switch 10 and the ball 95 at another position will push another ball 95 to move upward. The ball 95 can be reset and inserted into the selection switch 10 under the elastic action of the second spring 91, and the adjustment and use of the selection switch 10 can be completed, which is convenient to use.
