This utility model discloses a convenient drain ball valve switching tool for aquaculture, relating to the technical field of ball valve switching tools. It includes a switch handle holder, one end of which has a groove structure adapted to accommodate and engage the drain ball valve switch handle; the other end of the switch handle holder is a connecting end; a universal joint, one end of which is detachably connected to the other end of the switch handle holder; and a telescopic ratchet wrench, the torque output end of which is detachably connected to the other end of the universal joint and can drive the switch handle holder to rotate via the universal joint. This utility model can easily rotate the drain ball valve at the bottom of the aquarium, offering convenient, time-saving, and labor-saving operation, greatly improving the work efficiency of the aquaculture workshop.

The invention relates to the technical field of batteries, and provides an insulating film and a battery cell. The insulating film is used for wrapping the outer side of a pole group of a battery cell, and comprises a first film group, a second film group and a third film group, the first film group comprises a first film body, a second film body and a third film body which are sequentially connected along a first direction, the second film body is provided with a first bulge part and a second bulge part which are arranged at an interval in a second direction, and the second bulge part is provided with a via hole for a tab to pass through; the two ends, in the second direction perpendicular to the first direction, of the first film set are each connected with a second film set, each second film set comprises a first turnover body, a second turnover body and a third turnover body which are distributed in the first direction, the first turnover bodies are connected with the first film bodies, the second turnover bodies are connected with the second film bodies, and the third turnover bodies are connected with the third film bodies; the first film body and the second film body can be folded relative to the third film body and connected with each other, and the first folding body and the second folding body of each second film group can be folded relative to the first film group and connected with each other, so that the first film group and the two second film groups define a box body structure.

The invention relates to the technical field of biological medicine, and particularly discloses a preparation method of a collagen and anti-propionibacterium acnes gamma protein combined preparation, and the preparation method of the collagen and anti-propionibacterium acnes gamma protein combined preparation comprises the following steps: preparing anti-propionibacterium acnes gamma protein; adding water into the anti-propionibacterium acnes gamma protein and the recombinant III-type collagen, stirring and mixing, adding glycerol and a neutralizing agent, and mixing to obtain a uniform solution; the preparation method comprises the following steps: dispersing carbomer with water, adding a preservative and a humectant, mixing, finally adding the uniform solution, and mixing to obtain the required collagen and anti-propionibacterium acnes gamma protein combined preparation. The combined preparation prepared by the method can be used for effectively treating acnes, is remarkable in curative effect, does not generate drug resistance, is short in treatment cycle, can quickly eliminate skin damage, promote cell growth and adhesion and repair skin barriers, and does not generate new rash after healing.

The utility model belongs to the technical field of medical biological materials, and particularly relates to a self-driven deformation nerve pasting film. The self-driven deformation nerve pasting film comprises a self-driven layer (1) and an adhesion layer (2), the self-driven layer (1) comprises at least two nanofiber layers, and the porosity of the nanofiber layers is in gradient distribution from small to large in the direction from the upper surface to the lower surface of the self-driven layer (1); the adhesion layer (2) is arranged above the upper surface of the self-driven layer (1), and the adhesion layer (2) is used for adhering the whole self-driven deformation nerve pasting film to an outer nerve membrane. The self-driven deformation nerve pasting film provided by the utility model is self-driven and deformed in the presence of tissue fluid, so that dynamic adaptive wrapping is realized, and the complexity of a surgical operation is reduced.

This utility model discloses a plastic wrap packaging device for fruit packaging, relating to the field of plastic wrap packaging technology. The device includes a support frame, a mounting shaft, plastic wrap, and a cutting blade. Both ends of the mounting shaft are slidably connected to the inner wall of the support frame, and the plastic wrap is fitted onto the mounting shaft. This utility model, by incorporating a foot-operated cutting structure, allows users to cut the plastic wrap after packaging by pressing down on the cutting blade with their foot. This solves the problem of users typically using both hands to rotate the fruit and pull the plastic wrap roller to wrap it, and some fruits require both hands to hold after wrapping, making it inconvenient for users to operate the cutting device and thus achieving convenient cutting.
