The utility model discloses a kind of multi-grade adjustment rotary switches, including base, shell cover, rotating handle and contact assembly, rotating handle rotationally arranged between base and shell cover, and drive rod extending along its radial direction is provided;Contact assembly includes the multiple elastic structure's moving contact bridge of the shaft center of rotating handle as center annularly arranged in installation cavity, and multiple static contact pieces are arranged in base and respectively opposite multiple moving contact bridges, multiple moving contact bridges are connected and respectively located on the movement path of drive rod, drive rod respectively drives multiple moving contact bridges and multiple static contact pieces contact in rotating handle rotating process, by the mechanism of the wheel contact formed by drive rod and multiple moving contact bridges, operation pressure is significantly dispersed, avoid single moving contact bridge sustained stress, greatly reduce the mechanical load and fatigue degree of moving contact bridge, reduce the probability of heating, reduce wear and risk of fusion welding, extend mechanical service life.

The application discloses a hole transport layer doped with a glycine derivative and a preparation and application method thereof. The amino group (-NH2) in the glycine salt can interact with the polar group of Me-4PACz, helping the dispersion of Me-4PACz in a solution and on a nickel oxide surface. The benzene ring contained on the selected derivative can help the electron conduction of the hole transport layer, and the halogen substituent group can change the work function of the hole transport layer, form a highest occupied molecular orbital (HOMO) energy level matched with a wide-bandgap perovskite, reduce the non-radiative recombination of a hole transport layer / perovskite interface, improve the stability of a lower interface of a perovskite active layer, and significantly improve the efficiency and stability of a wide-bandgap perovskite solar cell prepared by applying the hole transport layer material.

The utility model discloses a linear type cutting anastomat with a movable handle self-locking function, which comprises a lower jaw component and an upper jaw component, the middle parts of the lower jaw component and the upper jaw component are rotatably hung together, the left end of the lower jaw component is provided with a nail propping seat component, and the right end of the lower jaw component is provided with a fixed handle; the left end of the upper jaw assembly is provided with a nail bin assembly, the right end of the upper jaw assembly is provided with an upper jaw framework, the middle of the upper jaw assembly is hinged to a movable handle obliquely extending to be located above the upper jaw framework, the top of the upper jaw framework is provided with a clamping hook assembly extending upwards, and in the closed locking state, the movable handle, the upper jaw framework and the fixed handle are closed and attached together. The clamping hook assembly and the movable handle are buckled, locked and connected together; in the unlocking state, the clamping hook assembly is separated from the movable handle, and the movable handle obliquely extends to be located above the upper jaw framework. During use, the clamping hook assembly and the movable handle are buckled, locked and connected together, separation of the movable handle and the upper jaw framework in the cutting and suturing process is effectively eradicated, and stability and safety are both good.

This invention relates to the field of cable technology and proposes a high-strength overhead insulated conductor, comprising a conductor and an insulation layer arranged sequentially from the inside out. The insulation layer comprises the following raw materials: polyethylene, ethylene-vinyl acetate copolymer, maleic anhydride-grafted polyethylene, reinforcing agent, antioxidant, ultraviolet absorber, and lubricant. The reinforcing agent includes modified silica, which is obtained by modifying silica with a silane coupling agent and polybutylene terephthalate. The conductor insulation layer provided by this invention has good tensile strength, solving the technical problem of insufficient strength of existing overhead insulated conductor insulation layers.
