A feeding structure for folding umbrella fabric includes a base and a suction cup. The suction cup includes a rotating end and an adsorption end. The rotating end is connected to a servo motor. Several adsorption ports are formed on the lower annular surface of the adsorption end. These ports are connected to an external vacuum extraction device through connecting holes inside the suction cup. The base is equipped with a feeding rod and a folding umbrella fabric mechanism. The feeding rod is vertically adjustable on the base. The folding umbrella fabric mechanism includes an embossing surface. The lower annular surface of the adsorption end is higher than the embossing surface. A negative pressure sensor connected to the connecting holes is provided on the base. The servo motor controls the rotation of the suction cup. When the suction cup rotates above the feeding rod, the feeding rod lifts the umbrella fabric to below the adsorption end. The suction cup then adsorbs the umbrella fabric through the adsorption ports. The servo motor rotates the suction cup, causing the adsorption end to rotate onto the embossing surface of the folding umbrella fabric mechanism. This invention provides uniform adsorption of the umbrella fabric, ensuring that the umbrella fabric does not pull up lower layers of umbrella fabric during the adsorption process.

The utility model discloses an adjustable clamp for a positioning support body, and belongs to the technical field of clamps for optical coated lenses. The base is a circular plate, symmetrical square through holes are formed in the central symmetry area of the circular plate, the square through holes are moving spaces of the positioning supporting body, positioning sliding rails are arranged on the non-supporting face of the base, and the handle, the positioning supporting body, the first positioning sliding rail and the second positioning sliding rail are fixed to a pair of parallel edges of the square through holes respectively. The first handle and the second handle are symmetrically fixed to the edge area of the non-supporting face of the base, and the two ends of the first positioning supporting body and the two ends of the second positioning supporting body are arranged on limiting sliding rails of the first positioning sliding rail and the second positioning sliding rail. The shape and the size of the clamp are changed by adjusting the positioning supporting body, the application range of the clamp is widened, and the utilization rate of the clamp is increased.
