Abstract

The utility model provides a pen for drawing four lines for drawing four-line lattices. The utility model is made up by a tabular handle, four jaw shape chalk cards and locking rings sheathed outside each chalk card respectively. The utility model arranges four pen cards on the tabular handle. After chalks are fastened respectively, the utility model can draw lines to complete the normal four-line lattices. Drawing the four-line lattices gets simple, convenient, labor-saving and time-saving. The utility model is used for the Chinese and the English teaching for the middle school and the primary school, and the other corresponding teaching.

Description

Pen for drawing four lines

Technical field

The utility model relates to the Pen for drawing four lines that setting-out is used.

Background technology

In Chinese language and English teaching, need on blackboard, draw four line lattice and be used to write Chinese phonetic alphabet and English alphabet.The method of existing picture four line lattice is to adopt ruler and chalk to draw the drafting that single line is finished four line lattice one by one by measuring good spacing, and its setting-out process trouble wastes time and energy.

Summary of the invention

The purpose of this utility model is at the problems referred to above, provides a kind of and can simplify setting-out process, time saving and energy saving Pen for drawing four lines greatly.

The technical scheme that realizes above-mentioned purpose is: a kind of Pen for drawing four lines that is used for picture four line lattice, it is by tabular handle and be distributed on four pawl type chalk cards on the handle front end face and place the retaining ring outside the card to constitute respectively.

The utility model technical scheme more specifically is: described chalk card is made of three claws through being uniformly distributed along the circumference and lateral surface is arranged to taper seat, and its inner ring surface that is placed on the retaining ring of outside is arranged to corresponding taper seat.

The utility model technical scheme more specifically also comprises: the claw of described chalk card is provided with external screw thread, and the retaining ring that matches with it is provided with internal thread.

The utility model is provided with four pen cards on the template handle, be installed respectively go up chalk after, can a setting-out finish four line lattice of standard, make the drafting of four line lattice become simple and convenient, time saving and energy saving, in being specially adapted to, the Chinese language of primary school and English is given lessons and other corresponding teaching.

Description of drawings

Fig. 1 is this Pen for drawing four lines structural front view;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the upward view of Fig. 1.

The specific embodiment

In conjunction with the accompanying drawings the specific embodiment of the present utility model is described:

Provide as accompanying drawing, this Pen for drawing four lines has one and is tabular handle 1, evenly is provided with four pawl type chalk cards 2 on the front end face of handle 1, is equipped with retaining ring 3 respectively in the outside of each chalk card 2.Its chalk card 2 can adopt three claws that are uniformly distributed along the circumference to constitute, and the lateral surface of each claw is arranged to the taper seat structure, the taper seat that the inner ring surface that is placed on the retaining ring 3 of its outside is arranged to match.The utility model also can be provided with external screw thread on the claw of chalk card 2, and on the retaining ring 3 that is placed on its outside the internal thread that matches is set.

When the utility model is specifically implemented, can adopt plastic monoblock moulding handle and chalk card, and retaining ring, during use chalk 4 be inserted respectively in the circular hole that claw surrounds, by moving forward retaining ring, with chalk locking card jail; Its claw and retaining ring are when taper seat cooperates, and the fixing effect of chalk can be better; And when claw and retaining ring when being threaded, the fixedly meeting of retaining ring on claw is more reliable.

Structure of the present utility model also is fit to constitute Pen for drawing four lines with the pen of other cylindrical structural.

Claims
