A fruit picker for fruit trees relates to fruit picking machines for fruit trees and comprises a clamp arm I, a clamp arm II, clamp heads, a support spring, a support rod, a pull rope and a trigger. The fruit picker is characterized in that the clamp arm I and the clamp arm II are hinged through a pin, the mutually symmetrical spoon-shaped clamp heads are arranged at the front ends of the clamp arm I and the clamp arm II respectively, the support spring is connected between the rear ends of the clamp arm I and the clamp arm II, the support rod is fixedly connected to the lower end of the clamp arm I, and the pull rope fixed to the lower end of the clamp arm II penetrates through an upper transverse through hole of the support rod to be connected with the upper end of the 'V'-shaped trigger rotatably connected onto the lower end of the support rod. The fruit picker is simple in structure, simple to operate, timesaving and laborsaving, can be used for picking fruits at high positions on a fruit tree highly efficiently, and is an ideal fruit picking tool.
