The vertical cylinder 401 is squeezed by the rotation of the arc frame 604, and the slider 601 is moved in the guide rail 3, so that multiple sliders 601 are approached or moved away at the same time, realizing the approach or distance of multiple suction cup bodies 5, and achieving the purpose of adjusting the diameter of the object adsorption position.

[0036] Going further:

[0037] In an optional embodiment: one side of the motor 606 is fixedly connected to the back side of the fixed rod 1 through a support, the rotating shaft of the motor 606 is fixedly connected to the top of the gear 2 607 , and the gear 1 605 is sleeved and welded on the surface of the upper end of the rotating drum 602 .

[0038] In this embodiment, the motor 606 works to rotate the gear 2 607 to drive the gear 1 605 to rotate, so that the rotating drum 602 connected to the gear 1 605 rotates, and drives the arc frame 604 to rotate and adjust.

[0042] Going further:

[0043] In an optional embodiment: the suction mechanism 4 includes a vertical cylinder 401, a fixed ball 402, a movable ball 403, a cover body 404, a hose 405, an air hole 406 and an air pipe 407, the top of the vertical cylinder 401 slides through the top of the slider 601, the top of the fixed ball 402 is connected to the bottom of the vertical cylinder 401, the movable ball 403 rotates on the inner wall of the fixed ball 402, and the top of the suction cup body 5 is connected to the bottom of the movable ball 403.

[0044] In this embodiment: the air pipe 407 is connected to an external suction pump to control the operation of the suction pump, and the gas in the suction cup body 5 is sucked through the cover body 404 and the hose 405 to form a vacuum inside the suction cup body 5, so that the suction cup body 5 can stably adsorb and fix the object.

Through the mounting plate 9, the device can be easily installed on the robot arm with the cooperation of bolts and nuts.

[0054] The working principle and use process of this utility model:

[0055] When the utility model is in use, the motor 606 drives the gear 2 607 to rotate, thereby rotating the gear 1 605, the rotating drum 602, the rotating disk 603 and the arc frame 604. The rotation of the arc frame 604 squeezes the vertical cylinder 401, so that the slider 601 moves in the guide rail 3, so that multiple sliders 601 are simultaneously approached or separated, and multiple suction cup bodies 5 are approached or separated, so as to achieve the purpose of adjusting the diameter of the object adsorption position. The range is adjusted according to the need to absorb fixed objects, and there is no need to use multiple rows of suction cups to adsorb and fix objects. The purpose of wide range of use and saving of the number of suction cups can be achieved. The air pipe 407 is connected to an external suction pump to control the operation of the suction pump. The gas in the suction cup body 5 is sucked through the cover body 404 and the hose 405 to form a vacuum inside the suction cup body 5, so that the suction cup body 5 can stably adsorb and fix the object. The movable ball 403 can be rotated and adjusted on the inner wall of the fixed ball 402, so that multiple suction cups can be rotated at a certain angle in multiple directions under the fixed ball 402, which can achieve a more stable effect when adsorbing objects with irregular surfaces.

[0056] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention.
