ABSTRACT:
An adjustable magnifier structure mountable on various lamp stands, being comprised of a magnifier, an adjustable post, an extensible rod and a clamping portion, wherein, the extensible rod is provided on the two ends thereof with the magnifier and the extensible rod respectively. The magnifier can be rotated to any desired angular position, and the extensible rod can be adjusted in displacement freely, hence the adjustable post can be adjusted to any position in a three-dimensional space freely. The clamping portion is connectable with any of various lamp posts, so that the accompanied practical effect of various lamps can be increased by mounting a magnifier on any of them. The structure of the present invention is novel, convenient and practical in being mountable on these lamp stands without holding of a magnifier by a user.
