Description

The English Electronic dictionary

Technical field

The utility model belongs to the teaching tool field, is specifically related to a kind of English Electronic dictionary.

Background technology

Along with scientific and technological development, the volume of English Electronic dictionary is more and more less, and its each button also becomes more and more less accordingly, and student particularly university student is thicker because of finger, very inconvenient when pressing English Electronic dictionary button.

Summary of the invention

The purpose of this utility model is the problem of inconvenience when solving the student by English Electronic dictionary button, and a kind of English Electronic dictionary is provided, and its technical scheme is as follows:

A kind of English Electronic dictionary, it comprises English Electronic dictionary body and key device, comprise key zone on described English Electronic dictionary body, described key device comprises convex lens, in convex lens lower surface center, cylindrical projections is set, be provided with handle at the convex lens upper surface, key device is connected with English Electronic dictionary body.

The beneficial effects of the utility model are: can utilize key device to press exactly required button, even the volume of English Electronic dictionary is less, button is less, also can easily use, and because of human factors, does not limit the volume of English Electronic dictionary.

the accompanying drawing explanation:

Fig. 1 is structural representation of the present utility model;

embodiment:

With reference to Fig. 1, a kind of English Electronic dictionary, it comprises English Electronic dictionary body 1 and key device 2, comprise key zone 1-1 on described English Electronic dictionary body 1, described key device 2 comprises convex lens 2-1, in convex lens 2-1 lower surface center, cylindrical projections 2-2 is set, at convex lens 2 upper surfaces, is provided with handle 2-3, key device 2 is connected with English Electronic dictionary body 1.

Preferably, key device 2 is connected with English Electronic dictionary body 1 by two elastic band 2-4, the end of two elastic band 2-4 is fixedly connected on respectively the both sides of described convex lens 2-1, and the other end of two elastic band 2-4 is fixedly connected on respectively the both sides of described key zone 1-1.

Preferably, the diameter of described cylindrical projections 2-2 is less than 1.5mm, and its lower surface cambered surface that is evagination.

Preferably, described handle 2-3 consists of two annulus, and two annulus are fixedly connected on the upper surface left and right sides of described convex lens 2-1, and the anchor ring of two annulus is oppositely arranged.

The using method of utility model and principle: convex lens 2-1 has amplification, can see button clearly, then by cylindrical projections 2-2, pushes button, and the diameter of cylindrical projections is thinner, can accurately press needed button.
