The adsorption surface of the first suction cup 3 and the adsorption surface of the second suction cup 4 are arranged opposite to each other.

[0017] In actual use, when the piston rod 21 of the cylinder 2 is extended, the piston rod 21 drives the No. 1 connecting rod 5 and the No. 2 connecting rod 6 to rotate, so that the No. 1 connecting rod 7 and the No. 2 connecting rod 8 rotate synchronously, so that the No. 1 connecting rod 5 and the No. 2 connecting rod 6 respectively drive the No. 1 suction cup 3 and the No. 2 suction cup 4 to move towards each other, and when the piston rod 21 of the cylinder 2 is contracted, the piston rod 21 drives the No. 1 connecting rod 5 and the No. 2 connecting rod 6 to rotate, and drives the No. 1 connecting rod 7 and the No. 2 connecting rod 8 to rotate synchronously, so that the No. 1 connecting rod 5 and the No. 2 connecting rod 6 respectively drive the No. 1 suction cup 3 and the No. 2 suction cup 4 to move towards each other, and during the opening and closing movement of the No. 1 suction cup 3 and the No. 2 suction cup 4 driven by the piston rod 21 of the cylinder 2, the adsorption surfaces of the No. 1 suction cup 3 and the No. 2 suction cup 4 are always in a vertical state.

When the clamping force is large, the large contact area is not easy to damage the surface of the workpiece.

[0019] Specifically: the No. 1 connecting rod 5 includes a No. 1 rod 51 and a No. 2 rod, the No. 2 rod includes an integrally formed rod A52 and a rod B53, the connection between the rod A52 and the rod B53 is hinged to the bracket 1, the two ends of the No. 1 rod 51 are respectively hinged to the rod A52 and the piston rod 21 of the cylinder 2, and the end of the rod B53 away from the rod A52 is hinged to the No. 1 suction cup 3.

[0022] Specifically, it also includes a spring 9, which is sleeved on the piston rod 21 of the cylinder 2, and the two ends of the spring 9 are respectively against the cylinder body of the cylinder 2 and the bracket 1.

[0023] In actual use, when the piston rod 21 of the cylinder 2 is retracted, the spring 9 is compressed, and at this time, the No. 1 suction cup 3 and the No. 2 suction cup 4 respectively adsorb the two sides of the workpiece.

[0024] In the above design, by providing the spring 9, the piston rod 21 can be effectively buffered by being compressed by the spring 9 when retracting, so that the No. 1 suction cup 3 and the No. 2 suction cup 4 will not cause excessive impact on the product when they come into contact with the product.

[0025] Specifically: the bracket 1 includes a horizontal plate 11, a first vertical plate 12 and a second vertical plate 13 respectively arranged on both sides of the horizontal plate 11, the first vertical plate 12 and the second vertical plate 13 are symmetrical about the cylinder 2, the two ends of the No. 1 connecting rod 7 are respectively hinged to the No. 1 vertical plate 12 and the No. 1 suction cup 3, the two ends of the No. 2 connecting rod 8 are respectively hinged to the No. 2 vertical plate 13 and the No. 2 suction cup 4, the No. 1 connecting rod 5 is hinged to the No. 1 vertical plate 12, and the No. 2 connecting rod 6 is hinged to the No. 2 vertical plate 13.

[0027] In the above design, the structural design and specific implementation method of the bracket 1 can effectively realize the installation of the No. 1 connecting rod 5, the No. 1 connecting rod 7, the No. 2 connecting rod 6 and the No. 2 connecting rod 8.

[0029] During actual use, the No. 1 connecting rod 5 and the No. 1 connecting rod 7 are respectively connected to the No. 1 suction cup 3 from both sides thereof, so as to limit the No. 1 suction cup 3 from both sides thereof.
