Writing pencil of the present invention, when the penholder level was shelved, described the first weighted spherical ball and the second weighted spherical ball all were positioned at the weighted spherical ball chamber, and pen core so that nib is regained in the penholder, forms protection under the effect of pen core back-moving spring.When needs write, after penholder is converted into vertical direction by horizontal direction, the 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 the first weighted spherical ball is greater than pen core back-moving spring elastic force, the first weighted spherical ball can be so that pen core moves down also so that nib stretches out outside the penholder.Then the second weighted spherical ball falls and is connected to the support bar rear end, the second weighted spherical ball can overcome support bar back-moving spring elastic force, so that rotate toward penholder inwall direction the support bar rear end, the support bar front end can not move toward the rear end so that pen core is pushed against rotating on the step that also finally is connected on the connector toward the penholder center position under the lever principle effect.Can normally write this moment.
When write complete after, the direction penholder, in the process of penholder by vertical steering horizontal direction, the second weighted spherical ball and the 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; so that nib is inner with pen core automatic retraction penholder, thereby be protected.
As optimization, the rear end of described support bar has one to the tilting section of penholder inwall direction bending.Be that the first weighted spherical ball and the second weighted spherical ball in the process of rolling, can not prop up by supported rod rear end, roll more smooth and easy.
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, when write complete after, only need the penholder level is shelved, nib is can the automatic drawing back penholder inner.Need not to press button or other operations, can realize the automatic drawing back function of nib, very easy to use laborsaving, also so that nib can access better protection effect.
