Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the present invention, unless otherwise expressly stated or limited, the terms "disposed," "mounted," "connected," "fixed," "sleeved," and the like are to be construed broadly, e.g., as either a fixed connection, a removable connection, or an integral part; can be mechanically or electrically connected; the two elements may be connected directly or indirectly through an intermediate medium, and the two elements may be connected internally or in an interaction relationship, and a person skilled in the art can understand the specific meaning of the above terms in the present invention according to specific situations.

Referring to fig. 1-5, the present invention provides a technical solution: a shell of a mobile phone charger comprises a shell 1, a rubber pad 2, a USB hole 3, a filter screen 4, a plug 5, an air cushion 6, a compression spring 7, a sliding groove 8, a baffle plate 9, a cylinder 10, a clamping plate 11 and a clamping groove 12, wherein the USB hole 3 is formed in the top of the shell 1, the plug 5 is fixed at the bottom of the shell 1, the rubber pad 2 is fixed on the periphery of the outer surface of the shell 1, the air cushion 6 is fixed inside the rubber pad 2, the filter screen 4 is fixed on the outer surface of the shell 1, the sliding groove 8 is formed in the outer surface of the shell 1, the baffle plate 9 is connected inside the sliding groove 8, the compression spring 7 is fixed on two sides of the outer surface of the baffle plate 9, the cylinder 10 is fixed at one end of the compression spring 7, the clamping plate 11 is fixed on one side of the cylinder 10, the clamping groove 12 is formed, preventing the shutter 9 from sliding in the chute 8.
