Elastic parts, it is arranged between the magnetic core bracket and described shell, for providing elastic force；

Resonance circuit, it is arranged in described shell, and according to the interval between first magnetic core and second magnetic core Distance change and produce electromagnetic signal, the resonance circuit include around second magnetic core set coil composition inductance.

Preferably, described shell includes pen shell and the low pen shell being spirally connected with the pen shell, and the coiling storehouse is arranged at The low pen shell.

Preferably, the internal diameter of first magnetic core is identical with the internal diameter of second magnetic core.

Preferably, the elastic parts includes rubber bag tank and insulated spring, and the rubber bag tank and the insulated spring are solid Located at end of the magnetic core bracket away from first magnetic core.

Preferably, the time writer also includes the circuit board for being arranged at described shell tail end.

Compared with correlation technique, time writer provided by the utility model, it is by by the first magnetic core and the second magnetic core phase To two faces be arranged to the plane being parallel to each other, so as to effectively reduce the shift motion of pen core；By the first magnetic core and Spacing distance change between second magnetic core, effectively regulating frequency it can change；The internal diameter of first magnetic core and the second magnetic core it is interior Footpath is identical, easy to process so as to make pen core outside dimension identical and simple in construction.

Brief description of the drawings

, below will be to needed for embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model The accompanying drawing to be used is briefly described, and drawings in the following description are only some embodiments of the utility model, for this For the those of ordinary skill of field, on the premise of not paying creative work, it can also be obtained according to these accompanying drawings other Accompanying drawing, wherein：

Fig. 1 is the schematic cross-sectional view of the utility model time writer.

Embodiment

The technical scheme in the embodiment of the utility model will be clearly and completely described below, it is clear that described Embodiment is only part of the embodiment of the present utility model, rather than whole embodiments.Based on the implementation in the utility model Example, all other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, is belonged to The scope of the utility model protection.

Referring to Fig. 1, the utility model provides a kind of time writer 100, including a hollow shell 1 and it is arranged at described shell Pen core 2, the first magnetic core 3, the second magnetic core 4, coiling storehouse 5, magnetic core bracket 6, elastic parts 7, resonance circuit (not shown) in 1 with And circuit board 8.

Described shell 1 includes pen shell 11 and the low pen shell 12 being spirally connected with the pen shell 11.The pen shell 11 and institute State the hollow structure that low pen shell 12 is both ends open, the pen core 2 is used for one end for writing one from the low pen shell 12 Opening is stretched out.

First magnetic core 3 is arranged in described shell 1 and is movably sheathed on the pen core 2.

Second magnetic core 4 is fixedly installed in described shell 1 and is sheathed on the pen core 2, first magnetic core 3 and institute It is plane arranged in parallel to state two relative faces of the second magnetic core 4.So, when the pen core 2 is not by ambient pressure, institute State the first magnetic core 3 and second magnetic core 4 fits together, gapless, now, the electricity of the coil composition in the coiling storehouse 5 The inductance value of sense is 0, the resonant frequency of the corresponding resonance circuit.Using changing first magnetic core 3 and second magnetic core 4 Between space change magnetic circuit impedance, and then change the purpose of inductance value, so as to realize the change of LC resonant frequencies.
