Abstract
The utility model relates to an automatic pencil with increased and fixing force, which is an automatic pencil which can enhance clamping and fixing force to a lead core, and has good adaptability to the diameter error of the lead core. A pencil nib is not easy to be broken. A pencil clamp sleeve is made of softer material which has proper elasticity. The inner wall of a nib hole is provided with proper convex veins or burrs. In this way, when the lead core is adjusted, the action of withdrawing the lead core can be played. When the lead core is fixed, bigger functions of auxiliary clamping and fixing the lead core can be played and the function of effectively protecting the lead nib can be played. A lead core clamp is opened and closed through four petals. In this way, the functions of clamping and fixing are added and the adaptability to the diameter error of the lead core is added.
Description
The increased fixing force propelling pencil relates to a kind of stationery of writing usefulness, particularly can strengthen the propelling pencil to the not easily broken again plumbous point of lead for retractable pencil clamping power and core diameter difference adaptive faculty.
Present known propelling pencil, it is to the clamping power of lead for retractable pencil and all less to the poor adaptive faculty in lead for retractable pencil footpath, easily broken again plumbous point, the scope of application is little, and practical value is low.
The purpose of this utility model provide a kind of can clamping thick, footpath, the footpath poor bigger not easily broken again plumbous point of lead for retractable pencil, propelling pencil applied widely.
The purpose of this utility model is achieved in that pen cap and penholder are to be threaded, and its inside is clamping the lead for retractable pencil folder, lead for retractable pencil folder lock is put ring, spring and sent lead pipe.Pen cap (or Casing with pen tip) is to adopt material that is soft and the suitable elastic force of tool to make, the sharp hole inwall of pen cap makes an amount of burr or burr simultaneously, can when adjusting lead for retractable pencil, replace former retaining glue ring (or also claiming damped ring etc.) like this and play the effect of lead for retractable pencil retaining, can play bigger auxiliary clamping lead for retractable pencil effect fixedly the time and to the sharp stronger protective effect of lead at lead for retractable pencil again; Lead for retractable pencil folder is that pintongs is opened, received, and has so just increased that it is opened, receipts amplitude and to the contact range of lead for retractable pencil, so also just increased the clamping power of lead for retractable pencil and the accommodation of core diameter difference.
Owing to take such scheme, this designs simplification is convenient to make, and has reduced cost and has improved practical value.
Engaging drawings and Examples below further specifies this pen.
Accompanying drawing is the pen cap of increased fixing force propelling pencil and longitudinal center's profile of penholder coupling part.
Pen cap (1) is to be threaded with penholder (6), and their inner orders are clamping lead for retractable pencil folder (2), and lead for retractable pencil folder lock is put ring (3), send lead pipe (4) and spring (5).
