Abstract

The utility model relates to a scriber, which comprises a scriber body, wherein the upper part of the scriber body is provided with a handle, the lower part of the scriber body is provided with a round hole. The round hole is internally provided with a sleeve, the lower part of the sleeve is provided with a pen clip, the upper part of the sleeve is fixedly connected with a pulling rod, the other end of the pulling rod penetrates through the scriber body and locates at the outer part of the scriber body, a spring is disposed between the upper part of the sleeve and the bottom of the round hole, the scriber body is provided with a notch, and the pulling rod is provided with a clamping block matched with the notch. When in use, a paintbrush is mounted in the pen clip and locked by a locking ring, then five equidistant parallel lines can be drawn by the scriber, when drawing four parallel lines, a cross rod can be pulled, which leads the pulling rod to move upward along axial direction, when the clamping block locates the position of the notch, the pulling rod is rotated, which leads the clamping block to be clamped in the notch, and then the four parallel lines can be drawn, as well as three parallel lines or two parallel lines can be also drawn by the scriber as required.

Description

A kind of scriber

Technical field

The utility model relates to a kind of teaching aid, specifically, relates to a kind of scriber of the many equidistant straight lines that can draw simultaneously.

Background technology

At present, in, in Chinese language, mathematics, geometry or the English teaching of primary school, teacher often need draw parallel lines on blackboard, teacher is when drawing parallel lines, be to use ruler mostly, at first measured spacing, with ruler and chalk each bar straight line that draws one by one, just be to use set square and ruler in addition then with ruler, set square is mobilely drawn each bar line at the another side of set square with pen one by one along ruler is parallel, setting-out process trouble wastes time and energy, and setting-out efficient is low.

The utility model content

Problem to be solved in the utility model is at above problem, and the scriber that a kind of setting-out process is simple, time saving and energy saving, setting-out efficient is high is provided.

For addressing the above problem, the technical scheme that the utility model adopted is: a kind of scriber, comprise the scriber body, described scriber body top is provided with handle, the bottom of described scriber body is provided with circular hole, be provided with sleeve in the described circular hole, the bottom of described sleeve is provided with pen clip, the top of described sleeve is fixedly connected with pull bar, the other end of described pull bar passes the outside that the scriber body is positioned at the scriber body, be provided with spring between the top of described sleeve and the bottom of circular hole, described scriber body is provided with draw-in groove, and described pull bar is provided with the fixture block that matches with draw-in groove.

The end that a kind of concrete prioritization scheme, described pull bar are positioned at the outside of scriber body is fixedly connected with cross bar.

A kind of concrete prioritization scheme, described pen clip is provided with retaining ring.

The utility model is taked above technical scheme, have the following advantages: in use, in pen clip, install paintbrush, lock by retaining ring, then just can be by scriber equidistant five parallel lines that draw, when drawing four parallel lines, can spur cross bar, pull bar is moved upward vertically, when fixture block is positioned at the draw-in groove position, rotating rod, fixture block is stuck in the draw-in groove, and four parallel lines that just can draw then can also use this scriber draw three parallel lines or two parallel lines as required, this scriber diverse in function, the setting-out process is simple, time saving and energy saving, setting-out efficient height.

The utility model is described in further detail below in conjunction with drawings and Examples.

Description of drawings

Accompanying drawing 1 is the structural representation of a kind of scriber among the utility model embodiment;

Accompanying drawing 2 be in the accompanying drawing 1 A-A to view.

Among the figure:

1-scriber body; The 2-spring; The 3-pull bar; The 4-fixture block; The 5-draw-in groove; The 6-cross bar; The 7-handle; The 8-pen clip; The 9-retaining ring; The 10-chalk; The 11-sleeve; The 12-circular hole.

The specific embodiment

Embodiment: as shown in Figures 1 and 2, a kind of scriber, comprise scriber body 1, scriber body 1 top is provided with handle 7, the bottom of scriber body 1 is provided with five circular holes 12, be provided with sleeve 11 in each circular hole 12, the bottom of sleeve 11 is provided with pen clip 8, chalk 10 is installed in the pen clip 8, the top of sleeve 11 is fixedly connected with pull bar 3, and the other end of pull bar 3 passes the outside that scriber body 1 is positioned at scriber body 1, is provided with spring 2 between the bottom of the top of sleeve 11 and circular hole 12, scriber body 1 is provided with draw-in groove 5, and pull bar 3 is provided with the fixture block 4 that matches with draw-in groove 5.

The end that pull bar 3 is positioned at the outside of scriber body 1 is fixedly connected with cross bar 6, and pen clip 8 is provided with retaining ring 9.

Also other paintbrushes can be installed as required in the pen clip 8.

In use, in pen clip 8, install chalk 10, by retaining ring 9 locking, then just can be by scriber equidistant five parallel lines that draw; When drawing four parallel lines, can spur cross bar 6, pull bar 3 is moved upward vertically, when fixture block 4 is positioned at draw-in groove 5 positions, rotating rod 3, fixture block 4 is stuck in the draw-in groove 5, and four parallel lines that just can draw then can also use this scriber draw three parallel lines or two parallel lines as required; In the setting-out process, can also be by pulling cross bar 6, make wherein several chalks 10 solid line that draws, the dotted line that draws of several chalks 10 wherein, after painting, can rotating tension bar 3, make fixture block 4 produce draw-in groove 5, under the active force of spring 2, paintbrush is returned to original position.
