[0010] The utility model has the following beneficial effects:

[0011] 1. The utility model is provided with a motor, which can drive the rotating shaft to rotate through the motor shaft when starting, thereby driving the turntable to rotate, and driving the sliding bar to slide in the track block through the cooperation of the arc track groove and the limit rod, so as to adjust the distance between the first connecting tube and the turntable, so as to adjust the position of the suction cup to adsorb the sheet metal part according to the size of the sheet metal part, to avoid the distance between the first connecting tube and the center of the turntable being too large, which makes it impossible for each suction cup to adsorb on the sheet metal part, and to avoid the distance between the first connecting tube and the center of the turntable being too small, which causes the adsorbed sheet metal part to be bent under force during processing.
