The invention discloses a tea-leaf pruning robot. The tea-leaf pruning robot comprises a first box. One side of the bottom of an inner wall of the first box is fixedly connected with a first fixing frame, and the bottom of an inner wall of the first fixing frame is fixedly connected with a first motor. One end of an output shaft of the first motor passes through one side of the first fixing frameand is extended to the exterior of the first fixing frame. One end of the first motor is fixedly connected with a first screw rod, and one end of the first screw rod is fixedly connected with the bottom of the inner wall of the first box through a connecting block. The surface of the first screw rod is sheathed with a first slider, and the bottom of the first slider is slidably connected with thebottom of the inner wall of the first box through the connecting block. The top of the first slider is fixedly connected with a connecting part. A machine frame is slidably connected between two sidesof the inner wall of the first box through the connecting block. The tea-leaf pruning robot relates to the technical field of the tea-leaf pruning. The tea-leaf pruning device is capable of solving problems that the labor intensity of a tea-leaf pruning worker is large and the working efficiency is not high.
