[0026] When the main light funnel 1 needs to further converge light and increase the condensing effect, the outer sleeve 3 is rotated counterclockwise, and based on the threaded connection of the external thread 11 and the internal thread 12, the outer sleeve 3 is moved to the condensing direction of the main light funnel 1, when the smooth inner wall of the outer sleeve 3 extends out of the lower end of the main light funnel 1, the length of the main light funnel 1 is increased to increase the condensing effect, and under the action of the external thread 11 and the internal thread 12, the outer sleeve 3 can be adjusted at different distances, when the outer sleeve 3 rotates different number of threads, the condensing effect of the main light funnel 1 is also different, which improves the condensing precision and practicability of the device, when the main light funnel 1 does not need to be condensed, the outer sleeve 3 is rotated clockwise to completely coincide with the connecting sleeve 2, reducing the occupied space, facilitating storage and transportation, and facilitating next use, and the external thread 11 and the internal thread 12 have a certain friction force, improving the connection strength between the outer sleeve 3 and the connecting sleeve 2, ensuring the stability of the main light funnel 1 during operation, and through the threaded connection, the installation and disassembly are facilitated, and the outer sleeve 3 is convenient for later maintenance and replacement.
