Claim:
1. A lens cover for a lens equipment which comprises a lens received at an opening of a lens housing, comprising: a tubular cover body, which comprises an attachment body having a tubular sidewall for detachably coupling at said lens housing in front of said lens, and a front frame coupled at a front edge of said attachment body, wherein a guiding slot is a through slot formed at a circumference of said cover body, wherein said guiding slot is formed in an arc shape to have two ends and is formed between said front edge of said attachment body and a rear edge of said front frame; a cover module which comprises a cover panel and a joint unit coupled between said sidewall of said cover body and a peripheral edge of said cover panel to enable said cover panel to be continuously moved among a covered position, an initial state of an uncovered position, and a final state of an uncovered position that two folding movements of said cover panel at two different directions are continuously provided between said covered position and said final state of said uncovered position, wherein said joint unit comprises a first rotatable shaft located at one end of said guiding slot and orientated parallel to said sidewall of said cover body to enable said cover panel to be sidewardly rotated about said first rotatable shaft at a planar direction of said cover body, and a second rotatable shaft orientated perpendicular to said first rotatable shaft, wherein in said covered position, said cover panel is supported at a front portion of said cover body at said guiding slot and behind said front frame for covering said lens, in said initial state of said uncovered position, said cover panel is rotated sidewardly about said first rotatable shaft of said joint unit and is slid out of said guiding slot behind said front frame for uncovering said lens, such that said cover panel is guided to slide between said rear edge of said front frame and said front edge of said attachment body to slide out of said guiding slot as said through slot, and in said final state of said uncovered position, said cover panel is rearwardly flipped via said second rotatable shaft of said joint unit to rest on said sidewall of said cover body, such that said cover panel is rotated sidewardly and flipped rearwardly in one continuous action from said covered position to said final state of said uncovered position, wherein said joint unit further comprises a first resilient element coupled at said first rotatable shaft for applying a pushing force against said cover panel to push said cover panel being rotated about said first rotatable shaft from said covered position to said initial state of said uncovered position, and a second resilient element coupled at said second rotatable shaft for applying a pushing force against said cover panel to push said cover panel being flipped about said second rotatable shaft from said initial state of said uncovered position to said final state of said uncovered position; and a locking mechanism extended from said cover body for releasably locking said cover panel in said covered position to prevent said cover body from sliding out of said guiding slot.
