The carbon fiber tubes 313 are used to hold the ball when catching it to prevent it from falling out of the gap.

[0033] The fixing frame 32 is in the shape of a trapezoidal structure and has a reinforcing rib inside. One end of the fixing frame 32 is connected to the cylinder 122 provided with one end of the piston shaft and the connecting sleeve 25 in the same direction, and the other end is provided with multiple fixing ends 321. Multiple fixing ends 321 are arranged on the carbon fiber tube 313 sleeved with the outer arc 31121. A single fixing end 321 is adjacent to the hand guards 311 located on both sides of the gripper 31, and two fixing ends 321 are closely adjacent to the hand guards 311 arranged in the middle of the gripper 31, thereby fixing the position of the hand guard 311 on the gripper 31, and further fixing the shape of the gripper 31.

[0034] The two outer brackets of the movable connecting frame 122 are respectively fixedly connected to the two mounting holes 312 on the hand guard 311 located at the middle position of the gripper 31, close to the outer arc 31121. When the cylinder 121 is inhaled, the movable connecting frame 122 pushes the mounting holes 312 in the direction of the gripper 31, so that the gripper 31 is closed; when the cylinder 121 is exhausted, the movable connecting frame 122 pushes the mounting holes 312 in the direction away from the gripper 31, so that the gripper 31 is opened.

[0035] Compared with the prior art, the ball grabbing device provided by the utility model realizes the grabbing of ball objects by setting a driving device, a mounting device 20 and a grabbing device 30. The motor 111 drives the first gear 112, and the second gear 113 rotates in engagement with the first gear 112. The main partition 22 is arranged on the second gear 113 through the first mounting groove, and is fixed to the second gear 113 through the secondary partition 23 and the limit block 24. The connecting sleeve 25 is arranged on the other side of the main partition 22 connected to the second gear 113, and the mounting device 20 connects the opening and closing driving device 12 and the grabbing device 30 to the second gear 113 through the connecting sleeve 25, so that the opening and closing driving device 12 and the grabbing device 30 rotate together with the second gear 113. The grabbing device 30 is made to rotate and transport ball materials. When the cylinder 121 is inhaled, the cylinder 121 pushes the movable connecting frame 122 in the direction of the gripper 31, so that the movable connecting frame 122 pushes the gripper 31 to close; when the cylinder 121 is exhausted, the cylinder 121 pulls the movable connecting frame 122 in the direction relative to the gripper 31, so that the movable connecting frame 122 pulls the gripper 31 to open, so as to achieve the grasping of ball-like objects.
