[0046] like Figure 7 As shown, specifically, before the embodiment is connected with the car, due to the tension of the left tension spring 45 and the right tension spring 46, the left cover plate 41 and the right cover plate 42 are close to each other and abut against each other, thereby closing the opening 32. At this time, the waterproof cavity 31 is in a sealed space, and the connector 2 is sealed in the waterproof cavity 31; at the same time, under the action of the reset spring 23, the drive rod 24 is located at one end of the guide groove 6 close to the shell 1; under the action of the left spring 73 and the right spring 83, the left stopper 7 and the right stopper 8 abut against each other; under the action of the first tension spring 95 and the second tension spring 96, the other end of the left locking block 93 is staggered with the position of the left boss 74, and the other end of the right locking block 94 is staggered with the position of the right boss 84.

[0047] like Figure 8 As shown, when it is necessary to connect with the car, by pressing the spanner 51, the spanner 51 moves, driving the rack 53 to move, so that the gear 54 and the reel wheel 55 rotate, and the traction rope 56 is rolled up onto the reel wheel 55, that is, the waterproof cover 3 can be driven to slide in the direction of the shell 1 by the traction rope 56; in the process of the waterproof cover 3 sliding, the end of the connector 2 abuts against the left inclined surface 47 and the right inclined surface 48, and under the action of the left inclined surface 47 and the right inclined surface 48, in the process of the waterproof cover 3 sliding in the direction of the shell 1, the end of the connector 2 pushes the left cover plate 41 and the right cover plate 42 to overcome the tension of the left tension spring 45 and the right tension spring 46 and move to both sides, thereby opening the opening 32, so that the connector 2 can extend from the waterproof cavity 31;

[0048] In addition, during the sliding process of the waterproof cover 3 toward the shell 1, the driving rod 24 slides along the guide groove 6 away from the end of the shell 1. When the driving rod 24 slides to the position of the left stopper 7 and the right stopper 8, the left stopper 7 and the right stopper 8 are retracted into the left accommodating groove 61 and the right accommodating groove 62 under the action of the first left inclined surface 71 and the first right inclined surface 81; after the driving rod 24 passes the left stopper 7 and the right stopper 8, the left stopper 7 and the right stopper 8 are abutted against each other again under the action of the left spring 73 and the right spring 83, and because after being plugged into the car, the car pushes the left locking block 93 and the right locking block 94 to move inward, so that the other end of the left locking block 93 abuts against the left boss 74 and the other end of the right locking block 94 abuts against the right boss 84, so that the left stopper 7 and the right stopper 8 are always abutted against each other, which can prevent the driving rod 24 from being reset due to the action of the reset spring 23.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention.
