The utility model provides a earphone frame for broadcasting and television director relates earphone frame technical field, including fixed cylinder frame, the inner wall fixed sleeve of fixed cylinder frame has the baffle, the upper surface fixed connection of baffle has support rod, the one end fixed connection of support rod has guide rod, the both ends movable sleeve of guide rod has the support sleeve that is symmetrical distribution, the one end of support sleeve penetrates and extends to the outside of fixed cylinder frame, the one side inner wall fixed connection of support sleeve has support spring, one end of support spring is fixedly connected with the one end of guide rod, through the shaping placement device, have realized the easy to head -wearing earphone when not using type placement, not only avoided head -wearing earphone when not using easily to be pressed by the object on the desktop, and make it convenient and the desktop adsorption fixed through the cooperation of suction cup, thereby improve the stability when placing, avoid to produce the falling damage, reduce the damage risk's effect.

The utility model discloses a green plant planting fixing device, and relates to the technical field of green planting, the green plant planting fixing device comprises a base, a tray, a planting plate and an inner tooth support block, the outer side of the base is provided with a water accumulation groove, vertical force arms are annularly distributed on the outer side of the base, and the outer sides of the vertical force arms are provided with adjusting mechanisms; an adjusting mechanism is arranged on the base, the adjusting mechanism adjusts the distance between the multiple sets of trays according to the types and heights of plants, positioning treatment of different types of plants is met, a positioning mechanism is arranged over the base, and the positioning mechanism adjusts the distance between the planting trays according to the height of climbing plants or potted plants, so that the growth height of the plants is conveniently controlled. In the using process, the trays are positioned on the outer sides of the vertical force arms, then according to the number of green plants and the height of the green plants, spacing adjustment and control are conducted on the multiple sets of trays, potted plants can be conveniently positioned, then plant growth gaps are controlled, and the situation that the plants are easily squeezed due to the too small spacing is avoided.

The utility model provides an ultra-smooth nasal feeding tube with a hydrophilic coating, which belongs to the field of medical instruments and comprises a nasal feeding tube body, one end of the nasal feeding tube body is in a pointed cone shape, a hydrophilic component is arranged on one side of the nasal feeding tube body, and a fixing component is arranged outside the nasal feeding tube body. According to the hydrophilic nasal feeding tube, the hydrophilic assembly is arranged, so that the effect of supporting the nasal feeding tube body is achieved; before the nasal feeding tube is used, the nasal feeding tube body is placed in normal saline to be soaked for 30 seconds, the hydrophilic coating made of polyvinylpyrrolidone absorbs water and expands to form the hydrogel layer, when the nasal feeding tube is inserted into the nasal cavity and the throat of a patient, the formed hydrogel layer can greatly reduce the friction coefficient between the outer wall of the nasal feeding tube body and the nasal cavity and the throat of the patient, and discomfort of the patient is reduced; meanwhile, the supporting wire made of the nickel-titanium alloy can improve the stability of the nasal feeding tube body in the bending process, and the situation that the inner cavity of the nasal feeding tube body is completely closed when the patient moves is avoided.
