Description
Technical field
The utility model relates to English-teaching aid; Especially a kind of English teaching chalker is related to.
Background technology
In process of English teaching, teacher needs to write on blackboard, and because English letter needs to write by lattice, teacher also needs at black lining out when writing on the blackboard for this reason.Existing ruling is loaded down with trivial details, and elapsed time is large, and scoring equipment volume is large, uses inconvenience.Need a kind of multifunction teaching chalker being easy to carry, being convenient to line for this reason.
Utility model content
The utility model provides a kind of English teaching chalker, comprises handle, fixator, line box three part; Wherein, handle comprises capping, chalk chamber, laser lamp, slideway, electric wire connecting junction; Fixator comprises power supply, magnet A, switch; Line box comprises fine rule, magnet B, rotating shaft, line wheel, crank.
Preferably, described fixator comprises upper and lower two parts;
Preferably, described fixator and handle are interconnected;
Preferably, described chalk chamber is placed in handle, and handle bottom is provided with capping;
Preferably, described handle side is provided with laser lamp, and the switch on laser lamp and fixator, power supply are interconnected by wire; Handle opposite side is provided with electric wire connecting junction;
Preferably, the slideway on described laser lamp and handle is interconnected;
Preferably, described fixator is provided with magnet A;
Preferably, the two ends of described line box are provided with magnet B;
Preferably, the rotating shaft in described line box and line are taken turns and are interconnected;
Preferably, described rotating shaft and crank are interconnected;
Preferably, described fine rule is wound around on online wheel;
Preferably, described fine rule and electric wire connecting junction are interconnected;
Preferably, described line wheel scribbles white powder;
Preferably, the switch on described fixator is rotary switch.
Because present blackboard is all adopt irony structure, so can be adsorbed on blackboard by magnet A handle, fixator when using the utility model; By magnet B, line box is adsorbed on blackboard; Can first handle, fixator be fixed on blackboard during use, then shake crank and move, arrive desired location and line box is fixed on blackboard, then flick dynamic fine rule, powder just can be made to be imprinted on blackboard, after springing four fine rules, line lattice will to be left on blackboard; Very easy to use, and can take away after using, be convenient to teaching; There is easy to carry, the simple advantage of structure; And when running into the plate face that can not use powder, (as blank) can switch activated four laser lamps on rotational fixture, after slideway regulates laser lamp position, just by laser, line lattice can be incident upon on plate face.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram.
Detailed description of the invention
A kind of English teaching chalker according to Fig. 1, comprises handle (3), fixator (16), line box (15) three part; Wherein, handle (3) comprises capping (1), chalk chamber (2), laser lamp (4), slideway (5), electric wire connecting junction (14); Fixator (16) comprises power supply (6), magnet A (7), switch (8); Line box (15) comprises fine rule (9), magnet B (10), rotating shaft (11), line wheel (12), crank (13).
Preferably, described fixator (16) comprises upper and lower two parts;
Preferably, described fixator (16) and handle (3) are interconnected;
Preferably, described chalk chamber (2) is placed in handle (3), and handle (3) bottom is provided with capping (1);
Preferably, described handle (3) side is provided with laser lamp (4), and laser lamp (4) is interconnected by wire with the switch (8) on fixator (16), power supply (6); Handle (3) opposite side is provided with electric wire connecting junction (14);
Preferably, described laser lamp (4) is interconnected with the slideway (5) on handle (3);
Preferably, described fixator (16) is provided with magnet A (7);
Preferably, the two ends of described line box (15) are provided with magnet B (10);
Preferably, the rotating shaft (11) in described line box (15) and line are taken turns (12) and are interconnected;
Preferably, described rotating shaft (11) and crank (13) are interconnected;
Preferably, described fine rule (9) is wound around on online wheel (12);
Preferably, described fine rule (9) and electric wire connecting junction (14) are interconnected;
Preferably, described line wheel (12) scribbles white powder;
Preferably, the switch (8) on described fixator (16) is rotary switch.
Because present blackboard is all adopt irony structure, thus can magnet A (7) handle (3) be passed through when using the utility model, fixator (16) is adsorbed on blackboard; By magnet B (10), line box (15) is adsorbed on blackboard; Use first handle (3), fixator (16) is fixed on blackboard, then crank (13) is shaken mobile, arriving desired location is fixed on line box (15) on blackboard, then flick dynamic fine rule (9), powder just can be made to be imprinted on blackboard, after springing four fine rules (9), line lattice will be left on blackboard; Very easy to use, and can take away after using, be convenient to teaching; There is easy to carry, the simple advantage of structure; And (as blank) can switch activated four laser lamps (4) on rotational fixture (16) when running into the plate face that can not use powder, saved laser lamp (4) position on slideway (5) is adjusted after, just by laser, line lattice can be incident upon on plate face.
