Description
Technical field
The present invention relates to teaching equipment fields, more specifically to a kind of teaching aid easy to use.
Background technology
When teacher's pointer refers to teachers indicate writing on the blackboard, picture rod.Old times teacher is for corporal punishment and urges on student's
Similar to the tool of ruler；Modern society imparts knowledge to students, and especially electronic teacher pointer has replaced substantially in academy's work.
In current educational work, educational mode that blackboard writing on the blackboard and lantern slide are combined has become mainstream, however nothing
It can not all meet both sides demand simultaneously by being traditional teacher's pointer or novel electronic teacher pointer.Therefore in order to make daily religion
Educating work can preferably carry out, and vast educator needs to carry multiple teacher's pointers, and need in use back and forth more
It changes, it is inconvenient.
Invention content
1. technical problems to be solved
For problems of the prior art, the purpose of the present invention is to provide a kind of teaching aids easy to use, for solution
The certainly above problem, the present invention adopt the following technical scheme that.
There is cylindrical platform in the side of a kind of teaching aid easy to use, including telescopic rod, the telescopic rod, described flexible
One end of bar offers the first groove, is equipped with the first elastic reel in first groove, cigarette on first elastic reel
Flexible cord is connected with the first fixation magnetite at the first groove notch, and the cylindrical platform is close to one end of telescopic rod
The second groove is offered, the second elastic reel is equipped in second groove, cigarette is flexible thin on second elastic reel
Rope, first elastic reel and the second elastic reel are by elastic cord elastic connection, connection at the second groove notch
There are the second fixation magnetite, telescopic rod mutually to be adsorbed by the first fixation magnetite and the second fixation magnetite with cylindrical platform, the column
Threaded one end of the platform far from the second fixation magnetite is connected with laser pen, and the cylindrical platform outside screw is connected with rotation lid,
And rotation is covered in the outside of laser pen, one end of the rotation lid is fixedly connected with fixed rope sling, and the side of the telescopic rod connects
It is connected to fastening screw.
Preferably, one end of the fixed rope sling is connected with small magnetic patch, and small magnetic patch is wrapped with falling prevention mat, without using religion
Teacher's pointer can be adsorbed on to blackboard surface when whip, while preventing fixed rope to be sleeved on when dropping unintentionally and destroying small magnetic patch.
Preferably, the telescopic rod top is hollow, and is transparent material, and telescopic rod top hollow part is fixedly connected with
Glo-stick.
Preferably, described first fix magnetite can be respectively in the first groove and the second groove with the second fixation magnetite
Free to slide at notch, when pulling the length that elastic cord is needed to us, sliding first fixes magnetite and second and fixes magnetic
Stone is to position appropriate, stuck elasticity cord.
Preferably, the elastic cord need to use wear-resistant material, due to elastic cord in use can for a long time with
Other components are in contact, admittedly needing to use wear-resistant material, improve product service life.
3. advantageous effect
Compared with the prior art, the advantage of the invention is that：
After this programme is by splitting the first fixation magnetite and the second fixation magnetite, telescopic rod and cylindrical platform can be held respectively,
It uses simultaneously, to achieve the purpose that deal with various teaching task.
Preferably, one end of fixed rope sling is connected with small magnetic patch, and small magnetic patch is wrapped with falling prevention mat, when without using teacher's pointer
Teacher's pointer can be adsorbed on to blackboard surface, while preventing fixed rope to be sleeved on when dropping unintentionally and destroying small magnetic patch.
Preferably, telescopic rod top is hollow, and is transparent material, and telescopic rod top hollow part is fixedly connected with fluorescence
Stick., still can be used in the weaker environment of light.
Preferably, it is equipped with circular gasket between cylindrical platform and laser pen, threaded connection between the two is made more to fasten.
Preferably, the first fixation magnetite and the second fixation magnetite can be respectively at the notches of the first groove and the second groove
Free to slide, when pulling the length that elastic cord is needed to us, sliding first fixes magnetite and the second fixation magnetite to fitting
When position, it is stuck elasticity cord.
Preferably, elastic cord need to use wear-resistant material, due to elastic cord in use can for a long time and other
Component is in contact, admittedly needing to use wear-resistant material, improves product service life.
