Description
Technical field
The utility model relates to teaching equipment and facility, is specifically related to a kind of change-fountain pen chalk sleeve automatically.
Background technology
Chalk is teacher's one of requisite equipment in teaching; but because chalk carries inconvenience; and often can paste in use on the body of user; therefore there is chalk sleeve; but traditional chalk sleeve can only press from both sides a chalk; be a teacher when talking about emphasis; the chalk of different colours often can be used to carry out special mark; but teacher will take out two chalks carries out special mark; but both waste the time like this; and use also inconvenient, and in order to solve the problems of the technologies described above, a kind of new technical scheme of special proposition.
Utility model content
The purpose of this utility model is the weak point existed to overcome above-mentioned prior art, and provides a kind of change-fountain pen chalk sleeve automatically, and it is easy to use, simple to operate, be easy to large-scale promotion application.
The technical solution adopted in the utility model is: a kind of change-fountain pen chalk sleeve automatically, comprise pullover, chalk, fixed bar, control device, body, switch and slip clamp, body is the cylinder of hollow, be connected with pullover on the left of body, pullover inside is provided with chalk A, chalk clamp B is provided with on the right side of chalk A, chalk clamp B is connected with tooth bar, tooth bar is connected with fixed bar, rack and pinion is meshed, gear is connected with the output shaft of motor, motor to be connected with control device by wire and control device is positioned at body inside, control device is connected with switch and battery respectively, body inwall is provided with two symmetrical chalk clamp A, one of them chalk clamp A inside is provided with chalk B, chalk B right-hand member is provided with geometrical clamp, geometrical clamp is provided with slip clamp, geometrical clamp is connected with hydraulic stem, hydraulic stem is connected with slide block, slide block is connected with slide rail, slide rail is respectively equipped with induction point A, induction point B and induction point C, body right side wall is provided with puts pen mouth, body lateral wall is provided with switch.
The beneficial effects of the utility model are: the chalk A and the chalk B that put into two different colours by putting pen mouth, wherein chalk A arrives pullover position, chalk
abe positioned on chalk clamp A, chalk A is first used to write, when needs picture emphasis, press switch, control device can control slide block and move to induction point B position, simultaneously, hydraulic stem extends, make geometrical clamp can clip to chalk A, clamped by slip clamp, hydraulic stem shortens, slide block moves to induction point C, chalk A is put into chalk clamp A inner, slide block moves to induction point A position again, consistent with said process, chalk B is moved to pullover inside and is fixed by chalk clamp B, chalk B so just can be used to come the place of picture emphasis, chalk A can be switched back repeating above-mentioned process, continue to use, can realize only needing carrying the mutual switching that a chalk sleeve just can realize between chalk, not only save the time and use easily.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
With reference to Fig. 1, a kind of change-fountain pen chalk sleeve automatically, comprise pullover 1, chalk, fixed bar 3, control device 4, body 16, switch 5 and slip clamp 7, body 16 is the cylinder of hollow, be connected with pullover 1 on the left of body 16, pullover 1 inside is provided with chalk A2, chalk clamp B21 is provided with on the right side of chalk A2, chalk clamp B21 is connected with tooth bar 20, tooth bar 20 is connected with fixed bar 3, tooth bar 20 is meshed with gear 19, gear 19 is connected with the output shaft of motor, motor to be connected with control device 4 by wire and control device 4 to be positioned at body 16 inner, control device 4 is connected with switch 5 and battery 15 respectively, body 16 inwall is provided with two symmetrical chalk clamp A18, one of them chalk clamp A18 inside is provided with chalk B6, chalk B6 right-hand member is provided with geometrical clamp 8, geometrical clamp 8 is provided with slip clamp 7, geometrical clamp 8 is connected with hydraulic stem 9, hydraulic stem 9 is connected with slide block 10, slide block 10 is connected with slide rail 13, slide rail 13 is respectively equipped with induction point A11, induction point B12 and induction point C14, body 16 right side wall is provided with puts pen mouth 22, body 16 lateral wall is provided with switch 5.Chalk A2 and the chalk B6 of two different colours is put into by putting pen mouth 22, wherein chalk A2 arrives the position of pullover 1, chalk B6 is positioned on chalk clamp A18, chalk A2 is first used to write, when needs picture emphasis, press switch 5, control device 4 can control slide block 10 and move to induction point B12 position, simultaneously, hydraulic stem 9 extends, make geometrical clamp 8 can clip to chalk A2, clamped by slip clamp 7, hydraulic stem 9 shortens, slide block 10 moves to induction point C14, chalk A2 is put into chalk clamp A18 inner, slide block 10 moves to induction point A11 position again, consistent with said process, chalk B6 is moved to pullover 1 inside and is fixed by chalk clamp B21, chalk B6 so just can be used to come the place of picture emphasis, repeat above-mentioned process again chalk A2 to be switched back, continue to use, can realize only needing carrying the mutual switching that a chalk sleeve just can realize between chalk, not only save the time and use easily.
