Stress luminous pen

Abstract

The invention discloses a stress luminous pen, and relates to the technical field of geological exploration tools. The stress luminous pen comprises a pen body and a sliding sleeve which is slidably connected with the peripheral side surface of the pen body, wherein the peripheral side surface of the pen body is fixedly connected with a concave mirror ring; a plurality of sliding grooves are uniformly formed in the peripheral side surface of the concave mirror ring; the concave mirror ring is positioned in the sliding sleeve; the bottom surface of the sliding sleeve is fixedly connected with afirst convex mirror ring; the top surface of the sliding sleeve is fixedly connected with a second convex mirror ring; the inner surface of the sliding sleeve is fixedly connected with a plurality ofsliding rails which are matched with the sliding grooves; one ends of the sliding rails are fixedly connected with the first convex mirror ring; and the other ends of the sliding rails are fixedly connected with a second convex mirror ring. According to the stress luminous pen, the sliding sleeve is arranged on the peripheral side surface of the pen body, the concave mirror ring fixedly connectedwith the pen body is arranged in the sliding sleeve, and the focal length of the light is changed by utilizing the relative displacement of the concave mirror ring and the two convex mirror rings, sothat the adjustment of the brightness and the irradiation range of the light is realized so as to be suitable for different writing environments in the field.

Description

technical field [0001] The invention relates to the technical field of geological exploration tools, in particular to a stress luminescent pen. Background technique [0002] At present, pencils are still the main recording pens in the field, but due to the harsh working environment in the field, there are often problems such as inconvenient alteration of records, easy wear and tear of handwriting, and poor light affects recording, so it is necessary to provide appropriate supplementary light when writing, and needs It has the function of altering. [0003] The field writing environment is changeable, the ambient brightness is high or low, and the light range required by the recorder is large or small. However, the recording pen at this stage only adds a supplementary light to the tip of the pen, and the area and brightness of the supplementary light are uniform. It is fixed and cannot meet the different writing needs of field records. Therefore, it is a technical problem t...
