CN201203963Y - Braille Curve Drawing Single Point Clamp - Google Patents

Abstract

This Braille curve drawing single-point pliers includes a pliers body and convex posts and recesses on both sides of the jaws. It is mainly used for blind people to draw curves. body, each time the jaws are closed, a point can be made, since there is only one point, there is no limit between points, it can be used to draw any curve, and it can be used to make regular points and reverse points. convenient.

Description

Braille curves drawing single-point pincers

Technical field

The utility model belongs to blind person's drawing appliance technical field, specifically relates to a kind of braille curve plotting instrument.

Background technology

The instrument that the blind person writes is the braille version that is made of rectangular 6 points, and the position of these points is relatively-stationary, and is the line segment shape, can not be at an arbitrary position goes up and pricks point, also just can't utilize its curve plotting figure.

Summary of the invention

The purpose of this utility model provides a kind of braille mapping apparatus that can draw arbitrary curve figure.

The technical scheme that its technical matters that solves the utility model adopts is: it comprises caliper, and the two sides of its jaw is respectively equipped with projection and depression in correspondence with each other.

Because the two sides of the utility model caliper jaw is respectively equipped with in correspondence with each other projection and depression, when jaw closed, the projection head end just in time was arranged in depression, during mapping, with braille paper place the depression jaw above, control caliper, jaw whenever closes once, can make a call to a point,, not have restriction between points because have only a some position, can draw arbitrary curve, and both can beat on schedule, can beat antipoints again, easy to use.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a main body synoptic diagram of the present utility model.

Among the figure: 1, caliper, 2, projection, 3, depression.

Embodiment

Shown in Figure 1, the utility model comprises caliper 1, and the two sides of its jaw is respectively equipped with the projection 2 and the depression 3 of mutual correspondence, projection 2 length are 1 centimetre, and the jaw inner face that is provided with depression 3 is the plane, simultaneously, in the punching of A4 braille paper optional position, jaw length is not less than 10 centimetres for convenient.

Claims (2)

1. A single-point pliers for Braille curve drawing, characterized in that it includes a pliers body (1), and the two sides of the jaws are respectively provided with corresponding convex posts (2) and recesses (3). 2. The Braille curve drawing single-point pliers according to claim 1, characterized in that the length of the convex post (2) is 1 cm, and the inner surface of the jaw with the recess (3) is plane.
