The ball head rod 4021 is slidably installed in the swing inclined hole slot 4031 of the swing slider 403 to realize driving the vibration connecting rod 302 to perform linear reciprocating motion by driving the pneumatic vibrator 301. The linear reciprocating motion of the vibration connecting rod 302 drives the ball head rod 4021 to slide up and down in the swing inclined hole slot 4031. The up and down sliding of the ball head rod 4021 drives the swing connecting rod 402 to rotate and swing on the rotating bearing 404. The rotation and swinging of the swing connecting rod 402 drives the swing clamping rod 401 to rotate and swing. The swing inclined hole slide groove 4031 is an inclined round hole slide groove. By adjusting the inclination angle of the swing inclined hole slide groove 4031, the rotation range of the swing clamping rod 401 can be adjusted.

[0064] In the present application, by setting a swing mechanism 4, the linear reciprocating motion of the vibration mechanism 3 can be converted into the rotational swing of the swing clamping rod 401. By pressing the trigger 102 to open the two-way valve 202, the pneumatic vibrator 301 can start to drive the swing clamping rod 401 to swing. When in use, by clamping the small berry branches with the swing clamping rod 401, the small berries can be shaken and vibrated to fall. At the same time, different amplitudes and frequencies can be adjusted to meet different picking needs and improve picking efficiency.

[0065] Specifically, the small berry picking device of the present application further includes an air compressor, which is connected to the air inlet end connector 201 of the air transmission mechanism 2 through a pipeline, and is used to supply air to the pneumatic vibrator 301. The air compressor is a small air compressor with wheels, which is easy to carry.
