Abstract
The utility model discloses a magnetic compasses used on a blackboard, which comprises a magnet base and a chalk sleeve fixing seat, wherein a magnet is mounted on the magnet base, and a fixing part is arranged on the magnet base; a chalk sleeve is arranged on the chalk sleeve fixing seat, and a flexible rope is connected between the fixing part and the chalk sleeve fixing seat. According to the structure, because one end of the compasses is fixed on the blackboard by magnet attraction, the phenomenon that the compasses shifts is not easy to occur, and the phenomenon of damaging the blackboard is also avoided; and due to arrangement of the chalk sleeve, the chalk is convenient for clamping.
Description
Technical field
The utility model relates to educational compasses.
Background technology
Now, for can easily be on blackboard wall chart paper, a lot of blackboards all are to adsorb magnet.But if utilize traditional educational compasses at the blackboard upper drawing circle, then the centering pin of compasses can stay hole on blackboard, therefore, can damage blackboard, in addition, is drawing bowlder, and the centering pin of compasses moves easily, therefore, comes difficulty and trouble can for the picture round belt.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of magnetic compasses that are used on the blackboard.
The technical scheme that solves the problems of the technologies described above is: a kind of magnetic compasses that are used on the blackboard comprise magnet base and chalk sleeve holder, and magnet is installed on the magnet base, and magnet base is provided with fixed part; Described chalk holder is provided with chalk sleeve, between fixed part and chalk holder, is connected with flexible strand.
The beneficial effect of the utility model is: owing to be that mode through magnet absorption is fixed on an end of compasses on the blackboard, therefore, be not easy to occur the phenomenon of compasses displacement, the phenomenon of blackboard also can not occur damaging; Owing to be provided with chalk sleeve, therefore, be convenient to the clamping chalk.
Description of drawings
Fig. 1 is the structure chart of the utility model.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further elaborated.
As shown in Figure 1, the magnetic compasses that are used on the blackboard comprise magnet base 1 and chalk sleeve holder 2, and magnet 3 is installed on the magnet base 1, and magnet base 1 is provided with fixed part 4; Described chalk holder 2 is provided with chalk sleeve 5, between fixed part and chalk holder, is connected with flexible strand 6.
In use,, therefore, be not easy to occur the phenomenon of compasses displacement, the phenomenon of blackboard also can not occur damaging owing to be that mode through magnet absorption is fixed on an end of compasses on the blackboard; Owing to be provided with chalk sleeve, therefore, be convenient to the clamping chalk.
