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 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.
