An adjustable bracket / stay for a movable wing such as a lid of a cold frame (greenhouse). The backet comprising a slidable element 102 coupled to the movable wing (204), the bracket having an elongate channel 104 with a plurality of secondary slots / spurs 106A-106C. A stopped 108 protrudes from the frame (202), the stopper slidably located in the channel 104, the stopper receivable in one of the plurality of slots 106 to retain the wing at one of several positions. The bracket includes a supporting element 110 supported by the movable wing to guide the slidable element 102; the supporting element 110 can be manually operated to displace the slidable element moving the stopper from slots 106 to the main channel permitting the movable wing to moved, e.g. raised or lowered.

The invention belongs to the technical field of crop seedling raising, and particularly relates to a cellar and cold shed integrated reliable temperature control sweet potato seedling raising method which comprises the following steps: S1, building an integrated greenhouse which comprises a cellar part and a cold shed part covering the cellar part, the cellar part is located below the earth surface, and sweet potatoes are stored in the cellar part; s2, in the germination accelerating period of the sweet potatoes, manure is put into the cold shed part to serve as a heating source, the manure is fermented to generate heat, and the temperature of the cellar part and the temperature of the cold shed part are increased; s3, after fermentation of the manure is completed, the fermented manure is applied to the seedbed in the cold shed part, then the germinated sweet potatoes are planted to the seedbed with the manure, and seedling raising is conducted. According to the method, the cold shed is built above the cellar, heat is generated through manure fermentation, additional heating equipment is not needed, seedling energy consumption and cost are remarkably reduced, sweet potato transfer is reduced, tuberous root transfer damage is avoided, and the germination rate is increased.

The invention relates to the technical field of medical instruments, in particular to an intraoperative nerve monitor anti-interference device and method based on self-adaptive filtering, the device comprises an anti-interference shell and a closed cover plate, the closed cover plate is fixedly connected with the top of the anti-interference shell through bolt sets arranged on the periphery, a monitor is placed in the anti-interference shell, and the anti-interference shell is fixedly connected with the closed cover plate through bolts arranged on the periphery of the closed cover plate. A positioning assembly used for stably limiting the monitor is further arranged on the periphery of the interior of the anti-interference shell. The anti-interference shell is of a three-layer structure comprising the protective frame, the heat dissipation cold frame and the electromagnetic shielding frame, and the electromagnetic shielding frame is provided with a carbon fiber reinforcing layer, a nickel-copper alloy conducting layer and a PEEK protective layer, so that liquid and instrument collision in an operation environment can be resisted, and external electromagnetic interference can be isolated; the positioning frame is adjusted to be tightly attached to the monitor through the inflation cavity, elastic allowance is reserved in cooperation with the adjusting spring and the damper, longitudinal buffering of the damping bottom pad and the limiting top plate is combined, and the influence of vibration in transportation and operation on the monitor can be reduced.
