When the lens needs to be disassembled and maintained, the slide bar 41 is pressed to the right. The slide bar 41 moves to the right and pushes the sliding block 43 to move to the right. The second spring 45 contracts, so that the block 44 is disengaged from the transverse groove of the card slot. At this time, the spring 12 rebounds forward, pushing the protective shell 13 forward, so that the block 44 enters the longitudinal groove of the card slot.
