Fixing device and mobile terminal provided with fixing device

Abstract

The invention provides a mobile terminal provided with a fixing device. The mobile terminal comprises a shell, wherein the shell comprises a side wall and a button hole formed in the side wall; and the shell is provided with a first accommodating cavity. The fixing device comprises a tray and a tray fixing assembly, wherein a convex column protruding outwardly is arranged on each side wall of the tray; the tray fixing assembly comprises a fixing body which is fixed in the first accommodating cavity and is arranged in a way of facing the button hole; each first side wall of the fixing body is provided with a guide groove; and the tray passes through the button hole such that the convex columns on the tray are inserted into corresponding guide grooves and move downwards under the guidance of the guide grooves. When the convex columns move to preset positions in the guide grooves, the tray is locked. When the convex columns move to other preset positions in the guide grooves, the tray is unlocked. The invention further provides the fixing device. The mobile terminal and the fixing device are simple in structure, and are reliable in buckling.

Description

technical field [0001] The invention relates to a fixing device and a mobile terminal with the fixing device.
