Technical Field

The utility model relates to the field of teaching equipment assistance, in particular to a marking tool special for English teaching.

Background

At present in the teaching, especially the teaching of english, the important link of the process emphasis of the writing normalization of word and letter, in order to teach the student standardize the writing of english letter and word, english mr will often draw three check of four lines on the blackboard and instruct to write, but need adopt ruler and the good distance of chalk survey to draw the drawing that the single line was accomplished to the distance drawing single line when writing on the blackboard, the single line is drawn not only slowly like this, inefficiency, waste time, and the interval between the single line is inhomogeneous, be difficult to reach the standard requirement, influence the teaching quality. The existing scriber is mostly a ruler with a fixed distance, is not easy to fix, is easy to slide when used for drawing a line, and is inconvenient to use.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects in the prior art, the utility model provides the marking tool special for English teaching, which is simple in structure, can be fixed at a position needing marking through the vacuum chuck, can be used for drawing three four lines by pushing the shell with a hand, is fixed through the clamping mechanism, is strong in fixity, and is convenient to disassemble and replace.

In order to achieve the purpose of the utility model, the utility model adopts the technical scheme that:

a marking tool special for English teaching comprises: the blackboard eraser comprises a shell, wherein the upper end and the lower end of the shell movably penetrate through a transverse supporting rod, square blocks are fixedly connected to the two sides of the transverse supporting rod, the bottom end of each square block is fixedly connected with a bottom supporting rod, the bottom supporting rods are fixedly connected with vacuum suckers used for sucking a blackboard, a clamping mechanism used for clamping a marking pen is arranged on the inner side of the shell, a slot used for inserting the marking pen is fixedly connected to the inner wall of the top end of the shell, and an arc-shaped cylinder arranged on the outer side of the marking pen is fixedly connected to the outer side of the bottom end of the shell in a wrapping mode.

Furthermore, the square block between the upper part and the lower part is fixed by a vertical support rod.

Further, the number of the marking pens is at least 4.

Further, the clamping mechanism includes: the clamping rods are arranged on two sides of the shell in a penetrating mode, the clamping rods are located at the inner side end of the shell and fixedly connected with the arc-shaped clamping pieces, and the clamping rods are located at the inner side section of the shell and wound with springs.

Further, the spring is located between the arc-shaped clamping piece and the inner wall of the shell.

The utility model has the beneficial effects that:

its simple structure fixes at required marking off position through vacuum chuck, and the shell is pushed to the hand, can draw three check of four-wire, and the marking off pen is fixed through clamping mechanism, and the fixity is strong, convenient to detach changes.
