Abstract

The invention discloses a magnifying glass which is convenient for field use and survival. It includes a ring-shaped inner frame, a circular lens and a cylindrical handle. The ring-shaped outer frame is sleeved on the outer diameter end of the ring-shaped inner frame, so that the ring-shaped inner frame and the ring-shaped outer frame are movably fixed together, and the ring-shaped inner frame can wrap around the circular concave hole. The axis rotates; the outer diameter end of the lower end of the annular outer frame is welded and fixed with the square column, the middle part of the square column is provided with a central circular through hole, and the lower end of the square column is set as a semi-cylindrical structure; the upper end of the columnar handle is provided with a square groove adapted to the square column , the rotating shaft is set in the left circular through hole, the middle circular through hole and the right circular through hole, so that the square column can rotate 90° around the rotating shaft in the square groove; the lower end of the cylindrical handle is provided with a cone tip; the length of the cylindrical handle is larger than that of the circular lens focal length. The invention not only can enlarge the object to observe the details of the object, but also can easily ignite grass and sawdust to make a fire under the strong sunlight, which is especially suitable for field use and survival.

Description

technical field [0001] The invention relates to the technical field of magnifying glasses, in particular to a magnifying glass which is convenient for field use and survival. Background technique [0002] In addition to magnifying the object and observing the details of the object, the magnifying glass can also ignite the grass and sawdust under the strong sunlight by focusing. When people are exploring in the wild, traveling, prospecting or conducting scientific research, in case they get lost, they can use the magnifying glass to ignite paper, plants and trees under the strong sunlight. Ordinary magnifying glasses usually only consist of a ring-shaped frame, a circular lens and a cylindrical handle. It is necessary to hold the cylindrical handle and wait under the strong sunlight for a long time. ,very troublesome. Contents of the invention [0003] The purpose of the present invention is to provide a magnifying glass, which can not only magnify the object and observ...
