Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1 and fig. 2, the utility model provides a prevent cell-phone charger that plug drops, including shell 1, at the both ends of shell 1 connecting plug 2 and USB interface 3 respectively. Two sliding grooves 4 are arranged in the shell 1, an opening at one end of each sliding groove 4 is connected with a sucker 5, and the two suckers 5 are positioned at two opposite sides of the plug 2.

On shell 1 be equipped with two grooves of stepping down 1.1 on the side of plug 2, every groove of stepping down 1.1 all with corresponding the coaxial setting of sliding tray 4 all sets up correspondingly in every groove of stepping down 1.1 sucking disc 5, sucking disc 5 highly be greater than the degree of depth of groove of stepping down 1.1, sucking disc 5 can stretch out groove of stepping down 1.1.

A piston 6 is connected in each sliding groove 4 in a sliding mode, a piston rod 7 is welded on one side of each piston 6, the end of each piston rod 7 penetrates through the corresponding sliding groove 4, and a fixing plate 8 is welded on the end, on the outer side, of each piston rod 7.

Each piston rod 7 is sleeved with a spring 7.1, one end of each spring 7.1 is welded on one side of the corresponding piston 6, and the other end of each spring 7.1 is welded on one side in the corresponding sliding groove 4.

When the plug 2 is inserted into the socket, the sucker 5 is attached to the side face of the socket, and then the fixing plate 8 is pulled to drive the piston rod 7 to move towards one side, so that the piston 6 moves in the sliding groove 4, and the sucker 5 is firmly adsorbed on the socket.

A through groove is formed in the side surface of the fixing plate 8 facing the housing 1, and the USB port 3 is inserted into the through groove.

In order to fix the distance between the fastening plate 8 and the housing 1, two threaded through-holes are provided on the side of the fastening plate 8 facing the housing 1, a bolt 9 is screwed into each threaded through-hole, and the threaded end of the bolt 9 faces the housing 1.
