Abstract

The utility model belongs to the technical field of the teaching aid design, a pointer is related to. The utility model discloses its structure is hollow cylinder, characterized in that: the surface of cylinder is along vertically having the scale mark, cylinder internally mounted has a plurality of magnet. The utility model provides a multi -functional pointer not only can work as the ruler and use when using, simultaneously, pointer can adsorb on the iron desk or other panels made of iron of teaching, prevents to roll, has made things convenient for pointer's use greatly.

Description

A kind of teacher's pointer

Technical field

The utility model belongs to teaching aid design field, relates to a kind of teacher's pointer.

Background technology

In teaching upper class hour, usually teacher's pointer can be used.Clear instruction content of saying is convenient in the use of teacher's pointer, is convenient to student and better understands said content, but teacher's pointer is mostly simple thin rod at present, and function singleness, meanwhile, teacher's pointer, because it is cylindrical shape substantially, is placed on desk and easily tumbles.

Utility model content

Technical problem to be solved in the utility model is: provide a kind of multi-functional teacher's pointer, can use as survey instrument, and teacher's pointer ontological adsorption theory can be prevented from tumbling on ironwork.

The technical solution of the utility model is: a kind of teacher's pointer, and its structure is the right cylinder of hollow, it is characterized by: described cylindrical outside surface is longitudinally with scale mark, and described right cylinder inside is provided with some magnet.

Technique effect of the present utility model is: the utility model provides a kind of multi-functional teacher's pointer, not only can work as ruler in use to use, meanwhile, on the irony desk that teacher's pointer can be adsorbed on teaching or other iron panels, prevent from tumbling, greatly facilitate the use of teacher's pointer.

Accompanying drawing explanation

Fig. 1 is the front elevation of the utility model teacher's pointer;

Fig. 2 is the longitudinal sectional view of the A-A along the line of the utility model teacher's pointer;

Wherein, 1-scale mark, 2-magnet.

Embodiment

See Fig. 1, it is the front elevation of the utility model teacher's pointer.See Fig. 2, it is the longitudinal sectional view of A-A along the line of the present utility model.A kind of teacher's pointer of the utility model, its structure is the right cylinder of hollow, and described cylindrical outside surface, longitudinally with scale mark 1, can realize its purposes as dimensional measuring instrument, facilitates teacher's use such as setting-out measurement when writing on the blackboard.Some magnet 2 is installed in described right cylinder.Magnet can stick with glue the inside at hollow circular cylinder, especially can paste along the inner ring at the inner two ends of hollow circular cylinder.

The utility model provides a kind of multi-functional teacher's pointer, not only can work as ruler in use and use, and meanwhile, on the irony desk that teacher's pointer can be adsorbed on teaching or other iron panels, prevents teacher's pointer from tumbling, greatly facilitates the use of teacher's pointer.

Claims (1)

1. a teacher's pointer, its structure is the right cylinder of hollow, it is characterized by: described cylindrical outside surface is longitudinally with scale mark (1), and described right cylinder inside is provided with some magnet (2).
