Preferably, this cell phone rear cover fixture also comprises and the integrated outer disk of this inner disc, and the area of this outer disk is greater than this inner disc and be positioned at the outside of this inner disc, and this back shroud has a through hole of shape and this inner disc coupling, is used for nested this inner disc.This through hole can hold this inner disc just, and it is thinner that this outer disk arranges, and this outer disk is slightly outstanding like this is convenient to the user and rotates this outer disk to control the flexible of these two snibs.This through hole plays certain position-limiting action to this inner disc, makes the user control this outer disk more convenient.
The present invention also provides a kind of mobile phone, comprise above-mentioned cell phone rear cover fixture, also comprise pusher side frame and a back shroud on the other hand, two sides of this mobile phone side frame have a keyhole, two keyholes are respectively used to these two snibs and pass, the shape of this back shroud and this lower plywood are complementary, and this back shroud and this lower plywood connect and fix.
Preferably, this cell phone rear cover fixture also comprises and the integrated outer disk of this inner disc, and the area of this outer disk is greater than this inner disc and be positioned at the outside of this inner disc, and this back shroud has a through hole of shape and this inner disc coupling, is used for nested this inner disc.
In the situation that these two snibs pass this two keyholes, this mobile phone side frame and this cell phone rear cover fixture just are locked.When needs unload this back shroud, only need this outer disk of rotation make this two snibs retract, at this moment just no longer be fixedly connected with between this mobile phone side frame and this cell phone rear cover fixture, this back shroud just can be easy to unload.
On the basis that meets this area general knowledge, above-mentioned each optimum condition, but combination in any namely get the preferred embodiments of the invention.
Positive progressive effect of the present invention is:
Cell phone rear cover fixture of the present invention, cell phone rear cover and mobile phone, be with reeded lower plywood by arranging one, snib with engaging tooth is set in groove, utilization is controlled snib with the inner disc of gear and is stretched the closure or openness cell phone rear cover, make the closure or openness operation of cell phone rear cover more convenient, and be conducive to long-term use.
