Description
Technical field
The utility model relates to pencil-lead technical field, specially a kind of propelling pencil lead of low residual core rate.
Background technique
Current propelling pencil generally when lead for retractable pencil there remains end a part, occurs as soon as lead in use
The case where core writing out of control and bad, it has to give up to fall using this section of lead for retractable pencil as residual core, thus cause biggish waste, not only
It is very uneconomical, and very not environmentally, to exit this section of lead for retractable pencil, need pressing propelling pencil button ten several times even twenties
It is secondary, user experience very cakes with moulded designs, and also so long one section is thrown away also unfortunately in vain, and sharpening core of propelling pencil is in handshaking
In, lead for retractable pencil currently in use gradually disengages the control for sending core mechanism lead for retractable pencil to grab, and after being detached from control, lead for retractable pencil will lose main
Radial control force is only left a wee bit frictional force of a mouth, although pen core will not also drop out at this time, the axis that generates when writing
Lead for retractable pencil can be made to rotate in mouth to component, lead for retractable pencil is in the state of " out of control ", no matter how penholder is rotated in this state,
Lead for retractable pencil all can be because of rotation and with one facing to the plane write, and the word person's handwriting write out in this way is too thick, without the vigour of style in writing without beauty
See, lead for retractable pencil feeling out of control is also very bad when writing, for eliminate this phenomenon then need many times pressing propelling pencil by
Button abandons this section of lead for retractable pencil, until new lead for retractable pencil leaks out a mouth, compression number it is sometimes much for several times more than, this user experience
Very cakes with moulded designs.
Utility model content

Including lead for retractable pencil and connecting pin, the upper and lower surface of the lead for retractable pencil is respectively equipped with connecting pin.
Preferably, the connecting pin is inclined surface structure.
Preferably, the connecting pin is boss structure.
Compared with prior art, the utility model has the beneficial effects that the propelling pencil lead of the low residual core rate is different from
Two end faces of existing sharpening core of propelling pencil are the smooth flats axially vertical with lead for retractable pencil, are respectively equipped with inclined surface or convex at both ends
Platform when inclined surface or boss dock, forms bite force, so when in use, first lead for retractable pencil in two lead for retractable pencil replacement intersections
It can still be stuck in second lead for retractable pencil lower surface and continue to use when using to end, and first lead for retractable pencil will not also be in pen tube
Rotation can also be write out the problem of use will not be wasted and be polluted completely without the old pen core of pressed several times nib taking-up
Word has the vigour of style in writing more attractive, also, inclined surface is easy molding with boss, facilitates processing.
