The utility model relates to a mulberry leaf plucker belonging to the agriculture producing device, which solves the technical problems of improving plucking speed, preventing and avoiding stopping leaf and leaf blade to fly during plucking process. The key point of the technical proposal of the utility model is that a tube body (13) is connected with two semicircular tube sheets by a shaft pin (12). The upper part of the tube body is provided with a protecting bud rod (6) and a fixing knife rod (5). An axes controlling device is arranged inside the tube body. The open and close are achieved by a spring (1) arranged on the shaft pin (12) outside the tube body (13) and a handle button (2) which is arranged on the spring (1). The bow hooks on two ends of the spring are inserted on the lower part of a dividing leaf rod (7) of a convex lump (15) hole of the tube body. A pair of collecting leaf sheathes (4) are fixed on the tube body symmetrically. The speed of plucking mulberry leaf is fast and the mulberry leaf germ is not damaged, thereby effectively avoiding and preventing the problem of flying of stopping leaf and mulberry leaf during plucking process.
