The utility model discloses a kind of anti-falling radio frequency coaxial connectors, including connecting male head and connecting female head, two additional buckling plates are symmetrically equipped at the handle of connecting male head, two additional buckling plates are fixed with connecting male head by two first bolts;Two additional buckling plates include connecting seat.The utility model in, by symmetrically adding mechanical interlocking mechanism by additional buckling plate and anti-falling buckle at handle, second reliable anti-falling guarantee is provided for traditional thread connection;When male head and female head are screwed, by the arc buckle on anti-falling buckle is pressed into the lock hole of additional buckling plate, the resilience of spring piece makes it tightly buckled, form rigid interlocking, can effectively resist the effect of vibration and torsion on thread pair, fundamentally prevent the rotation loosening and accidental falling of connection due to external disturbance, greatly improve the connection reliability and signal transmission stability of connector under complex working condition.

The present invention relates to an oncolytic virus and the use thereof, and specifically, an oncolytic virus having suppressed expression of a thymidine kinase (TK) gene and comprising genes encoding granulocyte-macrophage colony-stimulating factor (GM-CSF) and a complement regulatory protein; and the use of such a oncolytic virus . The oncolytic virus of the present invention maintains its efficacy even upon intravenous injection, and thus, it may also be applied to the treatment of various solid carcinomas and metastatic cancers in addition to superficial solid cancers. In addition, the oncolytic virus of the present invention acquires resistance to the attack of the body's complement system by expressing a complement regulatory protein on the surface of the virus, and thus, it is stable in the blood, and it maintains stable oncolytic activity upon intravenous injection, and thus, it may reduce the dose of the virus to minimize the side effects of anti-cancer drugs. Therefore, the oncolytic virus of the present invention may be usefully used for preventing or treating cancer.

The application discloses a two-stringed Chinese violin bow trajectory pressure auxiliary training device, which comprises a base, a guiding structure of the base is used for guiding a bow hair, a supported part is connected with the base and is used for supporting the base, and the supported part is provided with an adsorption structure which is used for being adsorbed to a sound post through negative pressure.

The utility model belongs to the technical field of cables for coal mining machines, and particularly relates to a cable with a protection mechanism, which comprises a buffer layer, a plurality of insulating layers arranged in the buffer layer, thin-wall seamless stainless steel tubes arranged in the insulating layers, and silicon-based fiber paste filled in the thin-wall seamless stainless steel tubes. Through the arrangement of the protective layer, the compression-resistant layer and the elastic layer, the cable can bear large physical pressure, pulling force and impact, it is ensured that the cable is not prone to being damaged in the falling and impacting process of coal gangue or large coal briquettes, the inner layer of the cable can be effectively protected when the cable is subjected to external force, and the cable can be effectively protected against external damage; the cable has good elasticity and can keep long-time performance in a high-strength friction environment, and the surface of the cable is prevented from being abraded; and the plurality of steel wires can wrap the shielding layer to form a layer of metal cover, so that coal gangue or large coal briquettes on the working surface of the coal mining machine can be more effectively prevented from falling, punching and smashing, and the cable core is prevented from being damaged by external mechanical force in the use process.

To provide a solid electrolyte battery that can suppress occurrence of an internal short circuit and is suitable for warm isostatic press. A solid electrolyte battery 10 includes a charge-discharge body 14 including a positive electrode layer 15, a negative electrode layer 16, and a solid electrolyte layer 17 disposed between the positive electrode layer 15 and the negative electrode layer 16, an outer body 11 housing the charge-discharge body 14, and collectors exposed to the outside of the outer body 11 at respective one ends and electrically connected to the positive electrode layer 15 and the negative electrode layer 16 at the respective other ends, where the outer body 11 is formed of a heat welding layer 20 covering the charge-discharge body 14 from the outside and including an insulative, first resin, a heat-resistant layer 21 stacked on the outside of the heat welding layer 20 so as to cover the heat welding layer 20 from the outside and including an insulative, second resin having a higher melting point than the first resin, and a metal layer 22 stacked on the heat-resistant layer 21 so as to cover the heat-resistant layer 21 from the outside and including metal.
