Abstract: The present disclosure belongs to the technical field of antimicrobial peptide (AMP) production, and relates to a medium for breeding a Hermetia illucens larva that produces a highly active antimicrobial peptide (AMP), a breeding method, and an extraction method of an AMP. The present disclosure provides a medium for breeding a Hermetia illucens larva that produces a highly active AMP, including wheat bran, where the medium has a moisture content of 65% to 70%. In the present disclosure, the medium can realize the rapid and effective production of the highly active AMP by the Hermetia illucens larva.

Abstract: A rotary positioning adjustment device includes a shaft sleeve and a connecting rod. A reel is fixedly connected with an end of the connecting rod; a fixed seat is sleeved on the connecting rod; the reel is arranged in the fixed seat; and a power storage assembly is installed in the shaft sleeve. The power storage assembly includes a power input piece, a second torsion spring and a power output piece; a first support leg of the second torsion spring is connected in a hooked mode with one side of an input block of the power input piece, and a second support leg of the second torsion spring is connected in a hooked mode with the other side of the input block. A curtain includes the rotary positioning adjustment device.

Abstract: A rotary positioning adjustment device and a curtain with the same are provided. The rotary positioning adjustment device includes a shaft sleeve (303) and a connecting rod (1). A reel (304) is fixedly connected with an end of the connecting rod (1); a fixed seat (305) is sleeved on the connecting rod (1); the reel (304) is arranged in the fixed seat (305); and a power storage assembly is installed in the shaft sleeve (303). The power storage assembly includes a power input piece (300), a second torsion spring (301) and a power output piece (302); a first support leg (315) of the second torsion spring (301) is connected in a hooked mode with one side of an input block (314) of the power input piece (300), and a second support leg (316) of the second torsion spring (301) is connected in a hooked mode with the other side of the input block (314). The rotary positioning adjustment device further includes a first torsion spring (310).
