By adopting technique scheme, make backstop do not press down in situation, by spring supporting, the Long Term Contact of having avoided presenting a theatrical performance as the last item on a programme with latch circle latch, thereby the broken flexible problem of piece latch.
The utility model is further set to: described positive stop is equipped with front spring stopper slot.
By adopting technique scheme, make spring when packing between positive stop and backstop, by the front spring stopper slot of positive stop, limited, avoided spring because of the spacing problem not exclusively being flown by bullet.
The utility model is further set to: in described backstop, be equipped with the rear spring stopper slot concentric with described latch circle slot to make way.
By adopting technique scheme, make spring when packing between positive stop and backstop, also spacing firmly by rear spring stopper slot when spring is limited by front spring stopper slot, further promoted the stability of spring between positive stop and backstop.
The utility model is further set to: described positive stop is equipped with latch circle stopper slot.
By adopting technique scheme, can make latch circle and front back-up ring become two parts, and when latch circle packs positive stop into, spacing firmly by latch circle stopper slot, when the latch in latch circle has damage, can realize replacing easily by changing latch circle.
The utility model is further set to: in described backstop, be equipped with and described latch circle slot to make way of presenting a theatrical performance as the last item on a programme concentric.
By adopting technique scheme, when backstop is pressed down, avoid the touching of latch circle and backstop, thereby realize pressing down completely of backstop.
The utility model is further set to: between described positive stop and backstop, be also provided with guiding locking mechanism.
By adopting technique scheme, can make positive stop and backstop in locking, backstop can also directionally move mutually, has extended useful life and the safety in utilization of plug-in AV terminal.
The utility model is further set to: described guiding locking mechanism comprises support plate screw, be arranged on the screwed hole of described positive stop and be arranged on the through hole of described backstop, and described support plate screw is connected with screwed hole through after through hole.
By adopting technique scheme, realized simply and easily the locking guide function of backstop and positive stop.
