More firm in order to make to connect between magnetic rings, the axial two ends of described magnetic rings and magnetic lid adopt strong magnets to make.
In order to match with taper chalk, the accommodation space that each inner chamber surrounds is truncated cone-shaped and the tapering of the tapering of truncated cone-shaped and chalk matches.
In order to install the chalk that different manufacturers manufactures, ensure that chalk does not rock in chalk sleeve, the inner face of described magnetic lid is provided with the elastic device for compressing chalk.
In order to improve the utilization rate of chalk, the described length often saving magnetic rings is 0.5-3cm.
Compared to prior art, the present invention has the following advantages:
(1) the magnetic powder pen cap provided by the invention, without the need to delivery device, only need take out front end one to save magnetic that magnetic rings is connected to rear end and cover front end can be made to expose a joint chalk, not only simple to operate, hand-held length does not change, can chalk be used to the shortest, chalk utilization rate is high, and chalk can not rub generation chip, and this chalk sleeve structure is simple in addition, diameter is tiny, easy to use;
(2) the magnetic powder pen cap provided by the invention, the axial both ends of the surface of magnetic rings are provided with even number magnetic regions and the magnetic pole of adjacent two magnetic regions is contrary, magnetic rings near time automatically calibrating absorption position, utilize the attracting principle of magnet heteropole that two magnetic rings can be made to be interconnected, during dismounting, only need spin magnetization ring, make the homopolarity magnetic regions of two magnetic rings relative, utilize the principle of magnet homopolar-repulsion can make two magnetic rings separately, connect and dismantle all very convenient;
(3) the magnetic powder pen cap provided by the invention, magnetic rings adopts strong magnets to make, and suction is strong, can guarantee the rigidity of chalk sleeve, ensures that respectively saving magnetic rings when using can not separate, and only has during rotation and magnetic rings could be taken off;
(4) the magnetic powder pen cap provided by the invention, when not using, directly can be adsorbed on back has on the blackboard of hiding iron plate, convenient and practical;
(5) the magnetic powder pen cap provided by the invention, easy to use, and low cost of manufacture is easy to universal, has wide market prospects.
