Gardening scissors include two blades facing each other, two connecting blocks, two covers and two handles, wherein each blade is equipped with a perforation at a middle section, and a locking board is extended from one side of rear end of two blades. The connecting blocks have a (half) shell body facing the cover, and a wedging slot with half-oval shape extending from rear end of the shell body. Front end of the wedging slot has a stopping edge, one side of which has a side wing extending therefrom. The side wing and the shell body both have locking holes for screws passing through, and front end of the shell body expandably has a protruding base that has a buffer body, and one side of the front end has a second locking board extending therefrom. The cover is symmetrically disposed to face the shell body, so that a second wedging slot, a second stopping edge, a second side wing and a second locking hole are formed on the cover. One end of the handle has an anti-slippery sleeve and the other end has a through hole.
