Writing pencil of the present invention, when the penholder level was shelved, described first weighted spherical ball and second weighted spherical ball all were positioned at the weighted spherical ball chamber, and pen core makes nib regain in the penholder under the effect of pen core back-moving spring, forms protection.When needs write, after penholder is converted into vertical direction by horizontal direction, first weighted spherical ball at first falls and by the narrowest place between the support bar (be support level position place), finally be connected on the connector of pen core rear end, because the weight of first weighted spherical ball is greater than pen core back-moving spring elastic force, so first weighted spherical ball can be so that pen core moves down and make nib stretch out outside the penholder.Second weighted spherical ball falls and is connected to the support bar rear end then, second weighted spherical ball can overcome support bar back-moving spring elastic force, make the support bar rear end rotate toward penholder inwall direction, the support bar front end makes pen core be pushed against and can not move toward the rear end on the step that rotates and finally be connected to toward the penholder center position under the lever principle effect on the connector.Can normally write this moment.
After finishing when writing, the direction penholder, in the process of penholder by vertical steering horizontal direction, second weighted spherical ball and first weighted spherical ball are rolled back in the weighted spherical ball chamber.This moment, support bar resetted under the effect of support bar back-moving spring; the support bar front end breaks away from the step of connector and rotates toward penholder internal chamber wall direction; pen core also rearward moves under the pen core action of reset spring after losing they sup-port and resets; make nib with the pen core penholder inside of withdrawing automatically, thereby be protected.
As optimization, the rear end of described support bar has a tilting section to the bending of penholder inwall direction.Be that first weighted spherical ball and second weighted spherical ball in the process of rolling, can not prop up by supported rod rear end, it is more smooth and easy to roll.
In sum, than prior art, only need when the present invention writes pen is holded up, can make nib stretch out and push against, can write, after finishing when writing, only need the penholder level is shelved, nib can automatic drawing back penholder inside.Need not to press button or other operations, can realize the automatic drawing back function of nib, very easy to use laborsaving, also make nib can access the better protection effect.
