Referring to fig. 4 and fig. 7, in the present embodiment, the unlocking mechanism 150 includes a rotation shaft sleeve 1511, a first toggle arm 1512 and a second toggle arm 1513, the rotation portion 1611 is rotatably disposed on the lock housing 110, the rotation shaft sleeve 1511 may be a cylindrical structure, the first toggle arm 1512 and the second toggle arm 1513 are disposed at intervals around a rotation axis of the rotation shaft sleeve 1511 and are both connected to the rotation portion 1611, the first toggle arm 1512 and the second toggle arm 1513 are disposed along different radial directions of the rotation shaft sleeve 1511, the rotation shaft sleeve 1511 drives the first toggle 1512 to selectively toggle the toggle mechanism 160 during the rotation along an unlocking direction (where the unlocking direction may be a clockwise direction as shown by an arrow in fig. 4) so that the toggle mechanism 160 drives the first latch assembly 120 to retract into the lock housing 110 or move away from the toggle mechanism 160, and driving the second toggle arm 1513 to selectively toggle the latch mechanism 140 to rotate or to move away from the latch mechanism 140.
