Description

A kind of primary Chinese teaching apparatus

Technical field

This utility model relates to a kind of primary school teaching apparatus, specifically a kind of primary Chinese teaching apparatus.

Background technology

In primary Chinese teaching, all can practise in the matts of standard during student's learning book writing of Chinese characters at the beginning, and teacher is when giving lessons in classroom, need to draw with pen and ruler the matts of standard before writing, but it is difficult between the straight line arbitrarily drawn keep equidistant, inconvenience is brought, thus reducing the teaching efficiency of teacher to teacher's teaching.

Utility model content

The purpose of this utility model is in that to provide a kind of primary Chinese teaching apparatus, with the problem solving to propose in above-mentioned background technology.

For achieving the above object, this utility model provides following technical scheme:

A kind of primary Chinese teaching apparatus, including screw rod and handle；Described screw rod is made of stainless steel；Described screw rod upper end is provided with chalk sleeve, and lower end is nipple；Described handle is made up of wood materials；Described handle upper surface has three screwed holes and power slot；Described screwed hole is positioned at the center of handle upper surface；Described power slot is positioned at the upper right side of handle upper surface；Described power slot is provided with slip lid, and the center on slip lid surface is provided with anti-skidding projection；The lower surface of described handle is blackboard eraser；Described handle front and the back side are respectively provided with a rubbing surface；Described rubbing surface is positioned at the center of handle front and back；The right side in described handle front is provided with time timer and time timer switch；Described time timer switch is positioned at the left side of time timer；Described right handle face is provided with circular magnet；Described circular magnet is positioned at the center in right handle face, and circular magnet can be adsorbed on the optional position of blackboard.

As further program of the utility model: described chalk sleeve is divided into left and right two parts and left and right two parts to be made up of reed.

As further program of the utility model: the distance between described screwed hole is equal.

Compared with prior art, the beneficial effects of the utility model are:

This utility model is reasonable in design, simple in construction, easy to use and one-object-many-purposes, not only can drawing but also can regard blackboard eraser, teacher can being allowed to draw the matts of standard very easily, thus improve the teaching efficiency of teacher simultaneously.
