Description

A kind of card fourth pencil of forming by the cap for brush, penholder

The utility model relates to the propelling pencil of wearing the volume cutter.

Lead-sharpening pencil on the modern market, the intrinsic knife rest of plug in its cap for brush, knife rest are short side frame inwall and insert solid two blades; When cutting lead for retractable pencil, lead ash pollutes handwriting etc. inside and outside can interspersing among the cap for brush from the lead-filling hole of knife rest and short side frame and the corresponding cap for brush tube wall square hole that connects thereof; Written awl point is short sliding, and uncomfortable pupil grips, and has the pawl pipe to pass copper cap, spring in its penholder and even is fixed in head; Because the cap for brush, nib are to cut core with fit, the form of trackslipping, the plumbous point of the V-shaped clamping of two blades in addition, impedance, and the plug spin of staff and cutting-in helical pitch thereof can not get even control, easily cause plumbous point revolve partially, broken and tear open cut disconnected, its plumbous point that can be whittled into is short, in addition the not tight nib of cap for brush cover.

The purpose of this utility model provides a kind of card fourth pencil of being made up of the cap for brush and nib, penholder, and it not only can evenly control spin, cutting-in, helical pitch when fining away, and can collect and airtight lead ash.

Structure of the present utility model is: cap for brush left side section is middle pipe, puts intrinsic knife rest, sealed film, little pipe in the middle pipe successively; Knife rest is formed side's taper lead-filling hole by E body, L shaped body, can help the second half section of plumbous point, prevents that plumbous point from revolving partially and disperse stressedly, and E body longitudinal wall has a long trough cutter groove to insert solid blade; The perforation of sealed film is collapsible and prevent lead ash to loose to little pipe; In the little pipe screw thread is arranged; There is tepetate to be sleeved on middle pipe, can collects lead ash; In the right output port of the cap for brush screw thread is arranged, can screw togather the spiral shell point of nib; Nib is convex, and there is screw thread on its protruding top, can screw togather with little pipe and cuts core according to its thread rotary orientation, pitch, reaches the purpose of even control spin, cutting-in, helical pitch.The cutting-in amount that the screw thread control is cut=lead footpath 2mm ÷ (the long 8mm ÷ pitch 0.5mm of plumbous point)=0.12mm/ revolution.

The utility model is because control spin that can be evenly small and cutting-in, helical pitch, and the back segment of plumbous point obtains knife rest and helps and stressed dispersion in addition, cuts each matter lead for retractable pencil so can be whittled into long plumbous point with fitting; Its tepetate, sheet rubber are effectively collected airtight lead ash, the cleaning of sharp student's class hour, gracefulness; Section suitable pupil in the protruding top of its nib grips, and sharp learning write correct set; The solid good hand touch of penholder is suitable for the solid large diameter color lead of dress in addition.

Below in conjunction with accompanying drawing, embodiment is described further to the utility model
