Summary:A folder clamp comprises a base, an operating rod and a clamping cover, one end of the operating rod is rotatably connected with the base through a main shaft, the main shaft is sleeved with a torsionspring, a torsion arm at one end of the torsion spring is connected with the operating rod, and a torsion arm at the other end of the torsion spring is connected with the clamping cover; wherein thefirst buckling piece is connected to the operating rod in a sliding mode, the driving mechanism is used for driving the first buckling piece to slide, and the base is provided with a second buckling piece which is buckled with the first buckling piece in a matched mode. According to the folder clamp, locking of the operating rod and the base is achieved through mutual buckling of the first buckling piece and the second buckling piece, and when the folder clamp is used, the first buckling piece is driven to slide so as to be disengaged from and buckled with the second buckling piece. And the operation of transversely mo
