Abstract
The invention discloses an extensible straightedge, which comprises a straightedge body and a sliding block, wherein the sliding block is matched with the straightedge body and can slide on the straightedge body. The extensible straightedge is simple in structure, a straight line with infinite length can be drawn by sliding the sliding block on the straightedge body, and the space is saved to the greatest extent since the whole structure of the extensible straightedge is compact.
Description
Technical field
The present invention relates to a kind of ruler, particularly relate to a kind of extensible ruler.
Background technology
Current student often will use ruler, the instruments such as set square when doing geometry exercise question.And often can encounter line oversize needs when drawing straight line and talk about at twice, or with a long ruler.Do i.e. wasting space but also lose time like this.Extensible ruler well solves this problem, and length can accomplish 150mm, but can draw the straight line of 250mm to endless.
Summary of the invention
The present invention is directed to the problem that will solve and provide a kind of extensible ruler, it can save space, draws the straight line of endless.
Technical scheme of the present invention is: a kind of extensible ruler, comprising: ruler main body and slide block, and described slide block coordinates with ruler main body, can slide in ruler main body.
The invention has the beneficial effects as follows: structure of the present invention is simple, is slided, can draw the straight line of endless, but overall structure is small and exquisite, very saves space again by slide block in ruler main body.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of specific embodiments of the invention.
Detailed description of the invention
In order to understand structure of the present invention, feature and other object further, the appended preferred embodiment of existing combination is described in detail as follows, and illustrated preferred embodiment is only for illustration of the technical scheme of invention, and non-limiting the present invention.
The specific embodiment of the present invention is as follows:
As shown in Figure 1,
Technical scheme of the present invention is: a kind of extensible ruler, comprising: ruler main body and slide block, and described slide block coordinates with ruler main body, can slide in ruler main body.
During use, first in ruler main body, draw straight line, after painting, thumb is pinned slide block and is fixed, and other fingers are pinned ruler main body and make its slip of postponing, and so just can make two line segment energy slitless connections.As repeated above action, the unconfined extension of line segment can be made down, until position of achieving the goal.
Claims (1)
1. an extensible ruler, comprising: ruler main body and slide block, is characterized in that: described slide block coordinates with ruler main body, can slide in ruler main body.
