Fig. 1, Fig. 2 show single needle driving structure.By being powered to coil 11, form electric current in coil 11, coil 11 with
Which contain iron core 12 formed generate magnetic force electromagnet, at this time upper end be the pole S, lower end be the pole N, swing rod 9 be one process
The permanent magnet of processing, lower end are the pole N, and upper end is the pole S, according to the principle that identical charges repel each other, there is a natural attraction between the sexes, gives in 12 axial direction of iron core
9 suction of swing rod, so that the support shaft ear 14 for being connected to swing rod 9 around lower end is swung to the left, thus the centre being connected with swing rod 9
Axis 6 drives mandril 5 to slide along curved surface 21 on the left of cam, and supporting element 4 is around side axis ear under the action of the power that mandril 5 is given
17 are rotated up, so that thimble 3 drives needle cap 2 to move up, needle cap 2 is raised at this time.Turn-off current at this time, needle cap 2
It does not fall out, because even blind person's hand touch, supporting element 4 gives axial direction of the power still along mandril 5 of mandril 5, so that top
Bar 5 has the tendency that oblique left movement, and oblique left and 7 curved face contact of cam of mandril at this time, cam 7 are completely fixed by bracket 8, from
And form the self-locking of total.
By being reversely powered to coil 11, form electric current in coil 11, coil 11 with which contain iron core 12 at generation
The electromagnet of magnetic force, upper end is the pole N at this time, and lower end is the pole S, and swing rod 9 is a permanent magnet by processing, and lower end is the pole N, on
End be the pole S, according to the principle that identical charges repel each other, there is a natural attraction between the sexes, give swing rod 9 thrust in 12 axial direction of iron core, thus make swing rod 9 around
The support shaft ear 14 that lower end is connected to is swung to the right, so that the jackshaft 6 being connected with swing rod 9 drives mandril 5 along on the right side of cam
Curved surface 22 slides to the right, and supporting element 4 is rotated down around side axis ear 17 under the action of the power that mandril 5 is given, so that
Thimble 3 drives needle cap 2 to move down, and needle cap 2 is entirely retracted to shell 1 at this time, and braille contact pilotage resets.
Above-mentioned specific embodiment is used to illustrate the utility model, rather than limits the utility model,
In the spirit and scope of protection of the claims of the utility model, to any modifications and changes that the utility model is made, all fall
Enter the protection scope of the utility model.
