Type slide rail develops rapidly, ultra-thin to will compress further keeper axial space, overweight to require that keeper increase stop part is held
Section product and intensity.2）Its used keeper, elastic component and inside and outside lock tabs, which cooperate, can be achieved locking and unblock,
Because keeper has two positions to stop under elastic component constraint, and the different passage of each position correspondence, if but solving manually
The misplaced position of keeper during lock, i.e. maloperation can cause slide rail cycle interruption to carry out.3）Elastic component needs to rivet.
It is unidirectional, i.e. external slide rail to locking in slide rail glide direction in two above technology（First slide rail）
With middle slide rail（Second slide rail）Withdrawal locking, and interior slide rail（3rd slide rail）With middle slide rail（Second slide rail）Pull-out lock
It is fixed.
