Description
technical field:
the utility model relates to a kind of mathematics and to give lessons special teacher's pointer of drawing.
background technology:
the pointer function used in current mathematical education is single, only has the function giving directions blackboard content, can not carry out at any time writing and drawing on blackboard, can not bring more convenience to teachers' instruction, and design lacks novel intention, inadequate hommization.
summary of the invention:
the purpose of this utility model is to provide a kind of mathematics and gives lessons special teacher's pointer of drawing.
above-mentioned object is realized by following technical scheme:
a kind of mathematics is given lessons special teacher's pointer of drawing, its composition comprises: teacher's pointer main body, one end cover of described teacher's pointer main body has antiskid glue sleeve, described teacher's pointer main body and described antiskid glue sleeve are provided with push-and-pull elongated hole, described teacher's pointer body interior is provided with inner chamber, in described inner chamber, motion bar is housed, described motion bar is connected with the push-pull button outside described teacher's pointer main body, limited step is provided with in the middle part of described inner chamber, between described push-pull button and described limited step, spring is housed, opening folder is equipped with in described motion bar end, chalk is clamped by clamp nut by described opening folder.
described mathematics is given lessons special teacher's pointer of drawing, and described teacher's pointer main body is taper, and cover has described antiskid glue sleeve one end to be butt end, and the other end is taper end; Described antiskid glue sleeve is provided with one group of anti-skidding projection.
the beneficial effects of the utility model:
1. the utility model use time first by chalk clamp opening folder on, by screwing clamp nut, chalk is fixed, antiskid glue sleeve one end of hand-held teacher's pointer, blackboard carries out explanation give directions, when needs to blackboard content carry out emphasis write picture time, push-pull button can be promoted with thumb, push-pull button is connected with motion bar, in pushing course, the chalk at motion bar top is sent inner chamber, what at this moment can meet teacher writes picture demand, also can be drawn by teacher's pointer, avoid mathematics teacher and say that class hour hand is held chalk drawing and can be stained with the problem of chalk dust by finger, protect the skin of teacher, make the hand skin of teacher can not be subject to the stimulation of chalk dust and damage, when not needing to write picture, unclamp push-pull button, then under the action of the spring, again return in inner chamber by motion bar, chalk can not reach the outside of teacher's pointer main body, avoids the waste that fractures of chalk.
the utility model novel in appearance, the use of antiskid glue sleeve allows teacher's pointer comfortable feel, and the design of anti-skidding projection makes teacher's pointer not slip out of the hand; This teacher's pointer to be placed on lectern because there is the restriction of push-pull button time on the shelf, can not arbitrarily roll, and avoids to tumble the situation of breaking on the ground and occur, and designs very hommization.
accompanying drawing illustrates:
accompanying drawing 1 is structural representation of the present utility model.
embodiment:
embodiment 1:
a kind of mathematics is given lessons special teacher's pointer of drawing, its composition comprises: teacher's pointer main body 1, one end cover of described teacher's pointer main body has antiskid glue sleeve 2, described teacher's pointer main body and described antiskid glue sleeve are provided with push-and-pull elongated hole 3, described teacher's pointer body interior is provided with inner chamber 4, motion bar 5 is housed in described inner chamber, described motion bar is connected with the push-pull button 6 outside described teacher's pointer main body, limited step 7 is provided with in the middle part of described inner chamber, spring 8 is housed between described push-pull button and described limited step, opening folder 9 is equipped with in described motion bar end, chalk 11 is clamped by clamp nut 10 by described opening folder.
embodiment 2:
mathematics according to embodiment 1 is given lessons special teacher's pointer of drawing, and described teacher's pointer main body is taper, and cover has described antiskid glue sleeve one end to be butt end, and the other end is taper end; Described antiskid glue sleeve is provided with one group anti-skidding protruding 12.
