Abstract

The invention discloses an intelligent terminal protective cover and a use method thereof, the clamping device comprises a base frame, a housing fixed on the base frame, at least two groups of locking components arranged around the clamping space, connecting rods corresponding to the locking components one by one and a driving component. Each locking part is elastically hinged with the base frame through a first elastic piece and can swing between an opening position and a clamping position, and the driving part penetrates through the housing and is hinged with all the connecting rods, and the locking parts are synchronously driven to move through the driving connecting rods. When the locking part moves from the opening position to the clamping position, the transmission path upwards passes over the dead point position to realize self-locking, so as to maintain stable clamping, and when the locking part is opened, the transmission path downwards passes over the dead point position to maintain the opening state. According to the invention, through tool-free operation of 'locking by pressing the housing, namely pressing the pivot, namely unlocking', and combining with the dead point self-locking mechanism, the quick assembly and disassembly and high-reliability locking are realized, and the problems of complicated installation, easy loosening and poor adaptability of the traditional protective cover are effectively solved.
