Problems solved by technology

[0004] There are many types of philatelic tools in the prior art, and the use is more complicated. For example, the Chinese patent "Four-purpose philatelic tweezers" with the authorized publication number CN2080891 has a convex magnifying glass inlaid at the end of the tweezers, and one piece of the tweezers is a ruler. There are millimeter length units and perforation rulers, which can be used to measure the format of stamps and perforation rulers; the other leaf of the tweezers is a ruler, engraved with imperial length units and perforation rulers, which can be used to measure in imperial units The format of stamps in units of length; the end of the tweezers is flat, without edges and corners
The above-mentioned philatelic tools include a magnifying glass and tweezers. In the process of use, it is more convenient to use a single tool, but the magnifying glass and tweezers cannot be used at the same time, and in a dark environment, the tools cannot be used normally to identify multiple stamps.

Abstract

The invention relates to a multifunctional philatelic tool, and belongs to the technical field of cultural recreation supplies. The multifunctional philatelic tool comprises a handle, a magnifying lens and tweezers; a mounting stand is arranged at the front end of the handle; the tweezers are fixedly connected to the mounting stand, and an axial lead of the tweezers is in the same straight line as that of the handle; an LED lamp is also mounted on the mounting stand; the amplifying lens is hinged to the head end of the handle; a control switch capable of controlling the LED lamp to be on and off is arranged at the tail end of the handle; the tweezers are prepared from stainless steel, and the process for processing the tweezers is also disclosed. The multifunctional philatelic tool is multifunctional and convenient to use; the philatelic tweezers are high in corrosion resistance, antibacterial property, wear resistance, heat resistance and other comprehensive performances.

Description

technical field [0001] The invention belongs to the technical field of recreational products, and relates to a multifunctional philatelic tool. Background technique [0002] Philately refers to the activities of collecting, appreciating and researching stamps and other philatelic products. There are currently about 30 million philatelists around the world. Most philatelists collect stamps for learning and researching the world's history, geography, Knowledge about flowers, plants, fish and insects, and people, so as to cultivate people's interest in meditation and self-cultivation patience, and improve self-cultivation. [0003] Stamps are miniature works of art. In the process of collecting stamps, special stamp collection tools should be used correctly. Stamp collection tools generally include stamp tweezers, magnifying glasses, measuring teeth, and mail bags. The tips of stamp tweezers are flat, smooth and rust-free , and the degree of tightness is suitable for clamping ...
