Clamp for cutting edge of circular blade

The invention relates to a processing device for a blade. The problem of high processing difficulty is solved, and the effect of low processing difficulty is achieved. In order to solve the problem, the invention discloses a clamp for a cutting edge of a circular blade. The clamp comprises a base, the base is vertically provided with a rotatable support rod, and the support rod is provided with apositioning plate. The positioning plate is vertically provided with a rotating shaft, and the rotating shaft is sleeved with a clamping piece for fixing the circular blade. The clamping piece is coaxially and fixedly provided with a ratchet wheel, the number of teeth of the ratchet wheel and the circular blade are the same, and a ratchet pawl matched with the ratchet wheel is rotatably connectedto the positioning plate. With the cooperation of the ratchet wheel and the ratchet pawl, the circular blade has the same angle of rotation every time, and the processing difficulty is reduced. 本发明涉及种刀片的加工装置，解决了加工难度大的问题，具有加工难度
