Embodiment 1: referring to attached drawing 1, a kind of attached USB interface with dust reduction capability shown in Fig. 4, including it is sheathed on USB
The cover 1 of interface 2；
The bottom of cover 1 is set as open, and the bottom of the left and right sides of cover 1 and close cover 1 is provided with limit hole 7, USB
2 one end of interface is connect with the bottom of shell 3, connector of the other end as smart machine, 3 left and right ends of shell with
The connection of first retaining spring, 4 one end, the other end of the first retaining spring 4 are connect with limited block 6, and the top of shell 3 passes through second
It is connected at the top of retaining spring 5 and cover 1；
It is also extended through at the top of shell 3 equipped with a conducting wire, one end of the conducting wire and connector are electrically connected, the other end of conducting wire
Extend outside through the top of cover 1 and toward cover 1.
It is dust-proof to USB interface 2 when not in use in USB interface 2 by cover 1 in the present embodiment, improve making for USB interface 2
Use the service life.
Specifically, manually USB interface 2 is pulled to outside cover 1 in the case where 2 use of USB interface, in this process,
Deformation occurs for second retaining spring 5, becomes tensional state, and when limited block 6 encounters limit hole 7, the first retaining spring 4 is from compression
State is restored to original state, and USB interface 2 is fixed on outside cover 1；
In the case where not using USB interface 2, manually limited block 6 is squeezed in cover 1, that is, squeezes the first positioning bullet
Spring 4, while the connection of USB interface 2 Yu smart machine is released, due to the self-characteristic of the second retaining spring 5, the second retaining spring
5 restore from tensional state to original state, and USB interface 2 will be retracted in cover 1 by the second retaining spring 5 by shell 3, are USB
Interface 2 provides dust-proof.
Any deformation does not occur for the original state expression of spring.For convenience of human contact's USB interface 2, the inner space of cover 1
It is as big as possible, it is ensured that manpower can enter in cover 1.
Wherein, cover 1 further includes guide post 51, is covered in outside the second retaining spring 5 outside guide post 51, is covered in outside guide post 51
Second retaining spring 5 guides the second retaining spring 5 to extend along guide post longitudinal direction；
Cover 1 further includes capping 12, and capping 12 is connected with 1 bottom of cover, one edge, in the feelings that USB interface 2 uses
Under condition, capping 12 is opened, and manually involves the taking-up of USB interface 2；In the case where USB interface 2 does not use, limited block is manually released
6, the fixation of limit hole 7, USB interface 2 are retracted to automatically in cover 1, cover capping 12, for dust-proof；
When extracting out or retracting in cover 1, conducting wire will not be by for protecting USB interface 2 for the rubber sleeve being arranged on wire guide 11
