Description

English four-line grid scriber

Technical Field

The utility model relates to an english teaching aid field, more specifically say, relate to an english four-wire check scriber.

Background

As is well known, in the existing english teaching, a teacher needs to draw four lines on a blackboard to write english, and the four lines are frame lines for limiting the position and size of english letters in english writing, and are similar to chinese character grid, and the structure of the four lines is composed of four uniformly distributed straight lines.

However, the traditional four-line grid drawing method is mostly completed through a ruler and a set square, is very inconvenient, is difficult to guarantee the regularity, cannot rapidly draw lines by pushing chalks which are arranged at equal intervals and driven by a supporting plate, and cannot adjust the distance between the chalks for adjusting the distance between the four-line grids.

Therefore, a large amount of english four-line check scribers have appeared among the prior art, and current english four-line check scribers, can not get into the circular slot through promoting the chalk, and clockwise rotation stripper bar, thereby compress tightly the chalk, also can not pass through the contact of sucking disc with the blackboard, make the bottom plate remain stable, a support plate is used for promoting, and drive the chalk and rule, the compression of spring atress, when no longer promoting the backup pad, the spring resumes deformation, promote the backup pad and reset, thereby it slides once more along original rule orbit to drive the chalk, increase and rule dynamics and definition, more can not pass through the rotation of nut, no longer press from both sides tightly the backup pad, can promote the screw thread post and remove along the shifting chute, thereby adjust and rule the.
