Abstract
The utility model provides a multifunctional sharpener for propelling pencils with thick leads, which can be used for easily sharpening the leads of the propelling pencils with the thick leads with pencil holders of different thickness. A lead fixing pit (9) is used for controlling the protruded length of the leads. A lead sharpening block (10) can be used for rubbing off lead dust on lead points (4). The utility model is characterized in that the upper part of a grinding wheel (5) in a lead dust collecting barrel (8) is provided with a rotary cover (12) which is provided with a pencil barrel (3) and a replaceable pencil barrel sheath (2), an axial line of the grinding wheel is collinear with a rotary central line of the rotary cover and is coplane with a central line of the pencil barrel, and the central line of the pencil barrel is intersected with a generatrix of the grinding wheel.
Description
The utility model is the invention about multi-functional thick propelling pencil sharpening device.
Thick propelling pencil is compared with thin propelling pencil, and its obvious advantage is: lead for retractable pencil is stablized, lead for retractable pencil frangibility and applied widely etc. not.Convenient inadequately when its weak point just is to use, need point lead for retractable pencil.Thereby, reduced its practical value.
For the lead for retractable pencil that solves thick propelling pencil points problem, so that give full play to its advantage, improve its practical value, at present, worked out a kind of thick propelling pencil sharpening device, for example: application number is 96216211.6 patent application.
The purpose of this utility model just provides a kind of multi-functional thick propelling pencil sharpening device.It can be at an easy rate with the lead for retractable pencil sharpening of thick propelling pencil; Can collect the lead dust that grinds; Can adapt to the different thick propelling pencil of penholder thickness; Can control the projected length of lead of thick propelling pencil; The lead dust that is ground on the plumbous point can be wiped.
The purpose of this utility model is achieved through the following technical measures: a kind of multi-functional thick propelling pencil sharpening device, this sharpening device is by Grinding wheel (5), lead dust collecting vessel (8), swivelling cover (12), pen bucket (3), removable casing (2), securing member (6), lead fixing pit (9) and wipe lead formations such as (10), one end of Grinding wheel has a lead dust collecting vessel, the other end of Grinding wheel has a swivelling cover, the pen bucket that one thick propelling pencil is arranged on the swivelling cover,, there is a duck eye at the bucket end of pen bucket, one removable casing is arranged at the top of pen bucket, removable casing diameter of bore difference, to adapt to the different thick propelling pencil of penholder thickness, with securing member Grinding wheel is fixed in the lead dust collecting vessel, swivelling cover and lead dust collecting vessel constitute lead dust and collect box, the axis conllinear of the rotation centerline of swivelling cover and Grinding wheel, the center line of pen bucket and the axis coplane of Grinding wheel and be mutually certain angle, the center line of pen bucket and a bus of Grinding wheel intersect, and, folded acute angle between the center line of pen bucket and this bus of Grinding wheel is between 4 °～20 °, the length that the degree of depth control lead for retractable pencil that leads fixing pit stretches out thick propelling pencil, lead for retractable pencil is neither fractureed and can be by sharpening, the edge that leads fixing pit can stop the penholder head end of thick propelling pencil enter lead fixing pit in, the center line that leads fixing pit relatively the elevation angle of level between 20 °～90 °, wipe lead and adopt soft material to make, and embed in this pit above sharpening device.
Advantage of the present utility model and effect are as follows:
1. be grinding to lead for retractable pencil, so lead for retractable pencil is not easy to fracture very much.
2. lead dust can directly be collected lead dust and collects in the box, and environment is not polluted.
3. plumbous its length of point that institute's grinding is good and tapering are very easy to guarantee.
4. strong to the different thick propelling pencil adaptability of penholder thickness.
5. lead for retractable pencil can fully be used, and makes waste minimum.
6. there is not lead dust on the plumbous point, clean during use.
7. face shaping is unrestricted, can make the shape of liking.
8. rational in infrastructure, principle advanced person, part is easy to processing and manufacturing.
9. service life is very long.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the profile according to the multi-functional thick propelling pencil sharpening device that the utility model proposes, and Fig. 2 is the vertical view according to the multi-functional thick propelling pencil sharpening device that the utility model proposes.
Describe structural shape and mode of operation in detail below in conjunction with Fig. 1 according to the multi-functional thick propelling pencil sharpening device that the utility model proposes.A kind of multi-functional thick propelling pencil sharpening device, its structural shape a: fixed axis (11) with the Grinding wheel coaxial line is arranged above the Grinding wheel (5), a bolt (7) is arranged below the Grinding wheel, with nut (6) Grinding wheel is fixed in the lead dust collecting vessel (8), matched in clearance swivelling cover (12) on the fixed axis, the pen bucket (3) that one thick propelling pencil is not only arranged on the swivelling cover, and also have one to lead fixing pit (9) and a wiping lead (10),, there is a duck eye at the bucket end of pen bucket, one removable casing (2) is arranged at the top of pen bucket, swivelling cover and lead dust collecting vessel constitute lead dust and collect box, the axis conllinear of the rotation centerline of swivelling cover and Grinding wheel, the center line of pen bucket and the axis coplane of Grinding wheel and be mutually certain angle, crossing and angle is preferably between 4 °～20 ° the center line of pen bucket with a bus of Grinding wheel, thereby guarantee the tapering and the length of the sharpening position of lead for retractable pencil on Grinding wheel and the plumbous point (4) that grinds, the diameter of bore of casing guarantees thick propelling pencil (1) plug freely, the length that the degree of depth control lead for retractable pencil that leads fixing pit stretches out thick propelling pencil, lead for retractable pencil is neither fractureed and can be by sharpening, the edge that leads fixing pit can stop the penholder head end of thick propelling pencil enter lead fixing pit in, the center line that the leads fixing pit elevation angle of level relatively is 90 °, wipe lead and adopt soft material to make, and embed in the pit.Its mode of operation is: the lead for retractable pencil of thick propelling pencil is stretched out and puts into lead fixing pit on earth the control projected length of lead.Finish changing a casing of suitable diameter of bore.With thick propelling pencil insert a casing to the pen bucket on earth.Hold pencil, along clockwise or counter clockwise direction, with the Grinding wheel axis is the rotating shaft rotation, make the bus of Grinding wheel change the position constantly with the contact wire that is ground the sharp bus of lead, lead for retractable pencil is also just by sharpening little by little, simultaneously, lead dust falls in the lead dust collecting vessel and is directly collected.The plumbous point of thick propelling pencil and wiping lead rubbed mutually just wipe lead dust on the plumbous point.
