The application provides an adjustable annular powder scattering bottle opening device for ostomy nursing, and belongs to the technical field of ostomy nursing. The device comprises a bottle body, a powder scattering component, an inner thread ring arranged at an opening of the bottle body, a powder scattering disc in the shape of a hollow circular truncated cone arranged at an upper portion of the inner thread ring, powder scattering portions equidistantly arranged from top to bottom on a side surface of the powder scattering disc, a plurality of powder scattering holes A arranged in an annular array on the side surface of the powder scattering disc, an adjusting ring arranged on the side surface of the powder scattering disc corresponding to each powder scattering portion, and powder scattering holes B equidistantly arranged on the adjusting ring and capable of controlling opening and closing of the powder scattering holes A. The application can not only improve powder scattering efficiency through annular powder scattering, but also adjust a powder scattering range according to a stoma diameter, and has high flexibility.

This invention discloses a coaxial powder feeding nozzle for laser cladding, relating to the field of metal cladding technology. The coaxial powder feeding nozzle includes a base, a laser generating mechanism mounted on top of the base, a powder feeding mechanism fixedly mounted on the outside of the base, and a nozzle connected through a channel tube at the bottom of the base. Four fourth sliding grooves are formed at equal angles along the circumference of the nozzle's interior. A rotating seat is rotatably mounted at the lower end of each of the four fourth sliding grooves, and a connecting pipe is fixedly mounted through the rotating seat. A slag removal component is provided between the rotating seat and the nozzle. The connecting pipe is connected to the base via an adjusting component. By using the connecting pipe and the adjusting component, the distance between the laser beam and the powder intersection point can be adjusted according to the different materials and fineness of the powder. Simultaneously, by using the adjusting component and the slag removal component, the slag removal component can clean the powder accumulated at the lower end of the connecting pipe and the bottom of the rotating seat.
