[0024] In the utility model, the limit assembly includes a plurality of sliding holes 17, and the plurality of sliding holes 17 are all provided on the lower surface of the rotating plate 6, and the plurality of sliding holes 17 are all slidably connected with a card bead 18, and the top inner wall of the plurality of sliding holes 17 is welded with a coil spring 16, and the coil spring 16 is fixed with the card bead 18, and the upper surface of the fixed plate 3 is provided with a plurality of arc-shaped grooves 19, and the card bead 18 is engaged with the arc-shaped groove 19, and the arc-shaped groove 19 will squeeze the card bead 18 to slide in the sliding hole 17, thereby squeezing the coil spring 16 to continue to compress and deform, and when the card bead 18 enters the next arc-shaped groove 19, the compressed coil spring 16 is released, so that the card bead 18 is stuck in the arc-shaped groove 19, and then the rotating plate 6 is fixed, thereby improving the stability of the device.

[0025] Among them, the reset component includes a connecting shaft 21, which is rotatably connected to the top inner wall of the annular groove 9, and the connecting shaft 21 is fixed to the arc-shaped rod 10. A torsion spring 20 is welded on one side of the connecting shaft 21, and the torsion spring 20 is fixed to the annular groove 9.

[0026] Among them, multiple leaf springs 8 are welded on the circumferential outer side of the fixed plate 3, and a friction block 7 is bonded to one end of the leaf spring 8, and the friction block 7 is in contact with the rotating plate 6, further strengthening the fixation of the rotating plate 6 and making the position of the rotating plate 6 more stable.

The circumferential outer walls of the multiple turning handles 4 are provided with multiple anti-slip grooves, and the anti-slip grooves are evenly distributed, which increases the friction of the turning handle 4 and avoids slipping when the rotating plate 6 is rotated.

[0027] Working principle: when it is necessary to expand the force-bearing area of ​​the suction claw, the rotating plate 6 is rotated by turning the handle 4, so that the inclined groove 5 squeezes the rolling ring 14 and the connecting frame 15, so that one end of the connecting frame 15 slides in the guide groove 11, and the other end of the connecting frame 15 squeezes the arc rod 10 to rotate outward, so that the force-bearing area of ​​the suction claw is expanded. During the rotation of the rotating plate 6, the arc groove 19 squeezes the card bead 18 to slide in the slide hole 17, thereby squeezing the spiral spring 16 to continue to compress and deform. When the card bead 18 passes over the current arc groove 19 and enters the next arc groove 19, the compressed spiral spring 16 is released, so that the card bead 18 is stuck in the arc groove 19, which solves the problem of small contact area with the material and poor adsorption effect, which causes the material to fall from the suction cup 12 and thus damage the material.

[0028] Finally, it should be noted that: for those skilled in the art, they can still modify the technical solutions recorded in the above embodiments, or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of this utility model shall be included in the protection scope of this utility model.
