[0031] The swing assembly can flip the material picking push rod 9 from a horizontal state to a vertical state. When clamping, the material picking push rod 9 can be driven to a horizontal state first, and then the material picking push rod 9 is extended to move the clamping ring 17 to the upper and lower sides of the gear to be clamped. Next, the clamping assembly moves the clamping ring 17 inward. At this time, the rubber clamp block 18 will retreat when it contacts the outer teeth of the gear. With the cooperation of the spring 22, it can be tightly clamped against the uneven teeth on the outer side of the clamped gear, and the clamping is more stable.

[0032] Then the swing assembly rotates the material picking push rod 9 to a vertical state, and the flip assembly allows the gear to rotate 90 degrees and place it horizontally on the plane below to complete the clamping, reducing various risks of manual picking and placing and reducing the physical exertion of workers.

[0033] In this embodiment, the swing assembly includes a drive motor 2, an arc groove 3, a swing connecting rod 7 and a limit shaft 8, one end of the drive motor 2 is fixedly connected to the support frame 1, one side of the arc groove 3 is opened on the support frame 1, the arc groove 3 is a quarter-circle arc groove 3, and there are straight grooves at both ends, one end of the swing connecting rod 7 is fixedly connected to the power output end of the drive motor 2, one end of the limit shaft 8 is slidably connected in the arc groove 3, and the other end of the limit shaft 8 is movably connected to the slot on one side of the swing connecting rod 7, and one end of the material taking push rod 9 is rotatably connected to the limit shaft 8;
