Description

A magnifying glass for engraving

technical field

The utility model relates to the field of engraving tools, in particular to a magnifying glass for engraving.

Background technique

A magnifying glass is a simple visual optical device used to observe tiny details of an object. It is a converging lens with a focal length much smaller than the apparent distance of the eye. At present, magnifying glasses are well known to people. With the growth and changes of user needs, various magnifying glasses have appeared on the market, including handheld ones, such as patent application number CN201720145418.0, and the date of authorization announcement is September 2017. On May 5, the name of the utility model is: a hand-held magnifying glass and a hand-held magnifying glass system. This application relates to a hand-held magnifying glass with a magnifying frame having a lens, a handle and a holder connected to the handle for holding the magnifying frame, the holder being formed with two annular regions The tensioning fork of the segment is open on the side facing away from the handle. In addition, the application relates to a hand-held magnifying glass system, which includes a handle and a holder connected with the handle for holding the magnifying glass frame. Here again, the holder is formed as a tensioning fork with two ring sections, which is open on the side facing away from the handle. The hand magnifier system also has a plurality of magnifier frames each with a lens, wherein the lenses in the different magnifier frames have different refractive powers and can be inserted selectively into the tensioning fork.

There are also ear-worn magnifiers, such as patent application number CN201720324277.9, the date of authorization announcement is February 16, 2018, and the name of the utility model is: a spectacle-type surgical magnifier with camera function. This application relates to a spectacle-type surgical magnifier with camera function, comprising a spectacle unit, including a frame and lenses, a magnifier unit, including an interconnected adjustment mechanism and a binocular magnifier, the lens barrel of the binocular magnifier is adjusted The mechanism is connected to the mirror frame, the lens barrel is correspondingly arranged in front of the lens, and the camera unit includes a camera head and a camera fixing bracket connected to each other, and the camera is connected to the magnifying glass unit through the camera fixing bracket , the headlight is fixed on the camera fixing bracket and is arranged directly above the camera. This application can ensure that the optical axis of the binocular magnifying glass, the optical axis of the headlight, and the optical axis of the camera always converge in the surgical field of view. The picture observed by the magnifying glass.

But, for engraving industry, above-mentioned two kinds of magnifying glass then can not satisfy the use demand well. During the engraving process, if you keep holding the magnifying glass with one hand, it will make the worker very tired, so the hand-held magnifying glass is very inconvenient to use, and its function is relatively single. The ear-worn magnifying glass is very easy to slip off the ear, which affects the work of the worker and is unreliable to use. In addition, during the carving process, wood chips and metal chips are often splashed from the object to be carved. If not properly protected, wood chips and metal chips can easily splash on the face of the worker and cause injury to the worker.
