Linkage lever 200 and grab lever 300 are connect with reduction torsion spring (not shown) respectively.The other end of linkage lever 200 is
End 220 is driven, driving end drives its swing, memory wire and its power supply device that deformation occurs of driving by memory wire
Connection.
Power supply device in the present embodiment includes the wire loop 400 for constituting closed loop, and memory wire 410 constitutes electric wire and returns
The a part on road 400, remaining position of wire loop 400 are electric wire 420.The input terminal 401 and output end of wire loop 400
402 connect with the positive and negative anodes of external power supply 1,2 respectively, are provided with what control wire loop 400 was turned on or off in wire loop
Touch reset switch 430.One end of grab lever 300 has the triggering end 330 cooperated with touch reset switch 430.In order to make
Wire loop 400 can the reasonable coiling in lock housing 100, be provided in the wire loop 400 in the present embodiment at least one around
Line wheel 500.
The working principle of the present embodiment is as follows：
As shown in connection with fig. 1, when bin is in unlocking condition, latch hook 10 at this time is located at outside, and grab lever 300 is multiple
Card slot 310 is made to be directed at latch hook 10 under the action of the torsional spring of position, and linkage lever 200 is under the action of reduction torsion spring wait cooperate
State, triggering end 330 at this time not with touch reset switch 430 contact, wire loop 400 is in an off state.
As shown in connection with fig. 2, when door body is closed, latch hook 10 at this time can be inserted into the card slot 310 of grab lever 300, grab
Lever 300 rotates, so that the linkage lever motion-stopping surface of the grab lever motion-stopping surface 320 of grab lever 300 and linkage lever 200
210 cooperation lockings, door is in the state that shuts at this time, and triggering end 330 is contacted with reset switch 430 is touched so that wire loop 400
