The invention provides a drop-out fuse, which comprises an insulator, a rainhat, a dropping device and a fusion tube, wherein the rainhat is formed by stamping a stainless steel plate; the left end of the rainhat is connected with the upper end of the insulator; a conductive component with a clamping groove is arranged in the rainhat; the dropping device comprises a fixed sheet, an integrated conductive copper sheet, a first conductive base and a second conductive base; the first conductive base comprises a base part connected with the lower end of the insulator and two opposite side walls; two hook grooves are formed in the two side walls respectively; the fixed sheet is connected with the integrated conductive copper sheet and the base part; the second conductive base is in slidable contact with the integrated conductive copper sheet; the lower end of the fusion tube is connected with the second conductive base; and the fusion tube is hung in the hook grooves in the first conductive base through a hook rail of the second conductive base, so that the fusion tube can rotate relative to the insulator and the upper end of the fusion tube is clamped in the clamping groove. By the rainhat and the first conductive base of the dropping device used by the drop-out fuse, stability of the overall structure of the drop-out fuse can be better ensured.

The invention discloses a balcony protecting fence device for the field of building. The device comprises a base, a protecting fence device body is arranged on the base, the protecting fence device isprovided with a cotton quilt base fabric device, a cotton quilt fixing device is arranged on one side of the cotton base fabric device, tempering glass is arranged on the protecting fence device to prevent the head of a child from extending out of the protecting fence through the gap between protecting fences and prevent carried objects of people from dropping out of a balcony through the gap between the protecting fences, and a cotton quilt can be simply and conveniently fixed and aired through the cotton quilt base fabric device and a cotton quilt fixing device. The balcony protecting fencedevice has the advantages of simple structure and high practicability.

The invention discloses a production component of a protein film. The production component comprises an output needle dropping out protein liquid, and a mold arranged below the output needle and usedfor receiving the protein liquid dropping out of the output needle, wherein the output needle is provided with a liquid inlet located at the upper part and a liquid outlet end located at the lower endpart; the component further comprises a blowing pipe arranged above the liquid outlet end of the output needle and blowing air downwards; after the output needle drops out a protein drop, the blowingpipe blows the protein drop down into the mold. Since the protein drop out from the output needle is blown down into the mold by the blowing pipe and spread into a film shape in the mold by a blowingair flow; a scraping step by a scraper in a production process is eliminated; the production speed is increased; the protein film spread by the air flow is uniform and smaller in thickness and has asmoother surface.
