Abstract
The utility model relates to a propelling pencil composing of a pencil cap and a pencil holder, which can evenly and tinily control the rotary force, the knifing and the lead for sharpening. The utility model can collect sealed lead dust and has the advantages of cleanness and elegance. The utility model has the structure that a cutter frame, a sealed film and a small round pipe are orderly fixed in the pencil cap, wherein, the cutter frame is composed of an E-shaped body and an L-shaped body, the pencil cap is sheathed with a dust cover, a pencil head is convex, and the convex top section of the pencil head is provided with a thread which is in screw connection with the small round pipe to sharpen. The pencil holder is hexagonal and is provided with a groove, the surface of the pencil holder has scales and is connected with a cone claw body and a lead core pulling sleeve, and a lead core can be extended in a fixed quantity mode. Because the convex top section of the pen head is suitable for grasping by pupils, the utility model is suitable for the learning and writing posture standard. Additionally, the pencil holder is solid, the handle is good, the utility model is suitable for installing a colored lead core with a big diameter, and a longer lead point and proper various qualities of lead cores can be cut.
Description
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
Fig. 1 is that the office of cap for brush embodiment is cutd open and installation diagram.
Fig. 2 is the shifting out of Fig. 1 intermediate slide E body, L shaped body, right view.
Fig. 3 is the schematic diagram of convex nib and propelling pencil adapted.
Fig. 4 is that the office of card fourth pencil embodiment is cutd open and installation diagram.
Fig. 5 is the hexagon cap for brush and middle pipe, the outline drawing of tepetate.
Fig. 6 is that the office of another embodiment of the cap for brush is cutd open and installation diagram.
Among the figure 1, the cap for brush, 2, middle pipe, 3, little pipe, 4, the E body, 5, L shaped body, 6, the cutter groove, 7, sealed film, 8, tepetate, 9, the convex nib, 10, penholder, 11, the spiral shell point, 12, taper claw body, 13, protruding top, 14, pull out plumbous cover.
Drawing explanation: Fig. 1 and Fig. 2 and Fig. 6 are for amplifying expression, and knife rest does not cut open, the cutter groove (6) of E body (4) longitudinal wall that is represent its blade.E body (4) laterally has a blade among Fig. 2.Among Fig. 4, convex nib (9), taper claw body (12), the end is cutd open and is shown that it wears plumbous perforation, pulls out plumbous cover (14) and does not cut open.Because of spiral shell point (11) is small, only represent its position.
Fig. 1, Fig. 2 and embodiment illustrated in fig. 3 in, the lead-filling hole of sealed film (7) can be V-shaped, is convenient to tack attitude lead for retractable pencil and passes, and can stick at little pipe (3) mouthful; The longitudinal wall of E body (4) and blade (6) structure are side's taper hole half, and L shaped body (5) is side's taper hole half, can adhere to middle pipe (2) inwall, also are beneficial to adjust its corresponding precision; Tepetate (8), middle pipe (2) can be screw thread in addition and screw, and staff can grip the anti-skidding line of the right section of the cap for brush (1), good hand touch.Convex nib (9) can screw togather or be adhered to the penholder of propelling pencil; When plumbous point touches blade, the right section of convex nib (9) can be fit to the cap for brush (1) right output port, can cut 1/2nd of its plumbous point this moment with hand control, when plumbous point is formed into two/for the moment, protruding top (13) screw thread of nib (9) just screws in little pipe (3) internal thread, but in addition 1/2nd of plumbous point is cut in screw thread control this moment.
