Abstract
A propelling pencil belongs to the technology field of stationery, comprising a pencil core, a nip and a pen that is connected with the nip. The propelling pencil is characterized in that the pen is provided with a rotating handwheel and a screw thimble that matches the rotating handwheel. The propelling pencil has reasonable design and new design. The pencil cores of different specifications and hardness can be replaced by requirements, which are suitable for writing, mechanical drafting and sketch and so on. In addition, the length of the refill that stretches out of the nib is able to realize stepless regulation, which is much convenient for writing.
Description
[technical field]
The utility model belongs to the stationery technical field.
[background technology]
Commonplace version is to adopt a thinner pen core in the existing propelling pencil, by button card pushing-type structure pen core is released piecemeal.This kind propelling pencil is because of its pen core is thin, specification is single, can't satisfy write, different purposes requirements such as drawing, sketch, and pen core very easily fractures.Though the propelling pencil of thick pen core has been released in the design of existing producer, its structure is still continued to use traditional approach, and the pen core length that ejects nib can't realize step-less adjustment, still has weak point in the use.Therefore old-fashioned wooden penholder pencil is still continued to use in some use occasion, and traditional wooden pencil utilization rate has only 4/5ths of raw footage at most, the timber resources that waste country is a large amount of.
[technology contents]
The utility model purpose is to overcome the defective that exists in the existing product, and design provides a kind of propelling pencil of regulating the pen core extension elongation by the screw rod thimble.
Described propelling pencil comprises pen core, nib and connected penholder, it is characterized in that being provided with on the penholder screw rod thimble of rotation hand wheel and corresponding cooperation.
This propelling pencil is rational in infrastructure, and is novel, can change the pen core of different size and hardness according to instructions for use.To be fit to various different purposes such as writing words, mechanical drawing, sketch.And the pen core length of stretching out nib realizes step-less adjustment, and it is more convenient to use.
[description of drawings and specific embodiments]
Fig. 1 is the propelling pencil structural representation.
As shown in the figure, nib 2 is spirally connected with penholder 3, also can be that close-fitting is pegged graft or the mode of snapping connects.Nib is provided with pen core centring ring 1 in 2, and pen core centring ring 1 is made by elastomeric material, and pen core 4 is played the role of positioning.Penholder 3 middle parts have an adapter sleeve 5, and rotation hand wheel 6 is arranged at adapter sleeve 5 inner chambers, rotation hand wheel 6 and screw rod thimble 7 threaded.Adapter sleeve 5 can adopt threaded with two parts up and down of penholder 3, also can be that close-fitting is pegged graft or other connected mode, and adapter sleeve 5 also can become overall construction design with one of two parts up and down of penholder 3.Screw rod thimble 7 afterbodys are shaped on guide pad 8, and cooperate at the corresponding gathering sill that is shaped on of penholder 3 inwalls.When rotation hand wheel 6 rotated, because of the guide effect of guide pad 8, screw rod thimble 7 can't rotate, because the impetus of screw thread can only move up and down, ejected pen core 4 to Len req, or return and make pen core 4 indentation smoothly.
