The first telescopic rod 22 and the second telescopic rod 23 are both arranged on the housing 21, and the first telescopic rod 22 and the second telescopic rod 23 are arranged in parallel. The telescopic rod drive 24 is installed on the housing 21 and is connected to the first telescopic rod 22 and the second telescopic rod 23 for driving the first telescopic rod 22 and the second telescopic rod 23 to extend outward from the housing 21 or contract inward into the housing 21; the first jaw arm 3 is arranged outside the jaw body 2, and one end of the first jaw arm 3 is connected to the first telescopic rod 22; the second jaw arm 4 is arranged outside the jaw body 2, and the second jaw arm 4 is located on the side of the outside of the jaw body 2 opposite to the first jaw arm 3.
[0040] In this embodiment, the robot dumping gripper drives the first telescopic rod 22 and the second telescopic rod 23 through the telescopic rod driver 24. The first telescopic rod 22 and the second telescopic rod 23 drive the first gripper arm 3 and the second gripper arm 4 to move towards each other to grip the grabbed part or move away from each other to release the grabbed part. Its structure is simple and the failure rate is low.
