Described method includes following steps:
Firstly, above structure is made to be located at initial position in the initial state, it can be adjusted, effectively improve in follow-up work
The working regularity of equipment.
Finally, holding the platform of starting writing on the other hand when equipment operation, another hand rotates the rotating block, makes the flower
The rotation of bond distance's axis, so that the kelly be made to rotate, the kelly on the right pushes the limitation bar of top to make the upper switch block
Rotation, since the first gear engages mating connection with the second gear, makes described so that the first gear be made to rotate
Rotation is connect, and the splined shaft so that the thread spindle be made to rotate since the thread spindle is threadedly engaged with the lifter plate
It is connect with the spline spline fitted, moves down the lifter plate and the splined shaft, to drive the plectane
And the platform of starting writing moves down, and extends pen, when need pen core stretching out the outlet plenum write when, due to the spline
Long axis is connect with the rotating block chamber spline fitted, pushes the spline long axis to move down the spline long axis, by institute
State that bullet stretches shaft and the bullet is stretched and is provided with spring between slot, when the spline long axis moves down, the idler wheel is described
It is moved inwards under the extruding of circle card chamber lower end wall, so that the idler wheel be made to skid off the round card chamber of top, and squeezes the bullet
It stretches slot and the bullet stretches spring between shaft, when the spline long axis is snapped down to the idler wheel by the following round card chamber
When, the bullet stretches slot and the bullet stretches the acting of the spring between shaft that the idler wheel sprung into the following circle card is intracavitary, and
The spline long axis is set to squeeze the spring on the lower switch block chamber lower end wall, the spline long axis and the switching chamber slide at this time
It is cooperatively connected, the rotation of the spline long axis will not make the upper switch block rotation, rotate the rotating block, make the rolling on the right
Wheel pushes the following limitation bar, and the lower switch block rotation is made to make the third gear so that the splined post be driven to rotate
Rotation rotates the 4th gear, and the 4th tooth on both sides since the third gear is engaged with the 4th gear
It rotates on the contrary, to the rotation that keeps the spiral slide cavity direction on both sides opposite, due to the side limiting groove and the limit
Slot processed limits the elevating lever and can only move up and down, and the spiral slide chamber rotation on the left side keeps the elevating lever on the left side upward
It is mobile, the described block on the left side is moved up, the spiral slide chamber rotation on the right moves down the described block on the right,
Meanwhile the rotation of the splined shaft rotates the 5th gear, matches since the 5th gear is engaged with the 6th gear
Conjunction connection, rotates the screw thread horizontal axis, connect since the screw thread horizontal axis is threadedly engaged with the platform out, makes the pen out
Platform is moved to the left, so that described block be driven to be moved to the left, the pen core on the right is skidded off the outlet plenum, when need using
When another pen core, the rotating block is inverted, when pen needs to retract, the holding rod is pulled, keeps the holding rod upward
It is mobile, carry the stretching bull stick upwards, to make the kelly move inwards, in the spring of the lower switch block chamber lower end wall
Under effect, moves up the spline long axis and the circle card for making the idler wheel protrude into top is intracavitary, when needing to replace pen
When core, due to it is described go out buccal mass be threadedly engaged and connect with the working chamber end wall, make described in the buccal mass out moves down and skid off
Working chamber is replaced pen core, to improve the diversity and linkage of pen.
Present device structure is simple, easy to use, and pen is in shortening state when not in use, occupies little space,
Easy to carry, this pen when in use, can be provided with according to the length for changing pen using comfortable and habit of user, this pen
Double pen cores can be used two different colors, same color also can be used, and can switch to after pen and ink are finished another
Pen core, does not need to carry another pen constantly, improves the convenience of device.
