Abstract
The utility model discloses a device special for sharpening short pencils. A pencil fixing device is arranged in a sleeve; the lower part of the fixing device is provided with an arc clamping plate; the clamping plate is connected with a clamping handle; the upper part of the clamping handle is perpendicular, and the lower part of the clamping handle is of an inclined arc; the middle of the clamping handle is movably connected with a longitudinal shaft; two ends of the shaft are connected with the wall of the sleeve; the wall of the sleeve is provided with a horizontal threaded pipe; the threaded pipe is provided with a screw; the head of the screw is in contact with the upper part of the clamping handle; a horizontal spring is arranged on the upper part of the clamping handle; the other end of the spring is connected with the wall of the sleeve; the screw and the spring correspond to each other horizontally and are positioned in the same vertical plane; the inner wall of the sleeve is provided with a positioning device; a distance from the positioning device to the bottom opening of the sleeve is less than 1.2cm. The device can firmly clamp a short pencil, and provides convenience for a user to sharpen the short pencils. The device also can fix ultrashort pencils, so that the user continuously uses the pencils, the pencils are saved to the maximum and the waste of resources and the like is reduced to the maximum.
Description
technical fieldthe utility model relates to a kind of device, specifically relates to a kind of special purpose device of cutting short pencil.
background technologywhen pencil remains to such an extent that only have 3-4cm long, these pencils are inserted in and in extension pipe, can also continue drawing and write, but if it is just not too easy to cut these pencils, because sharpening a pencil with cutter, especially cut very short pencil and will take larger strength, general pencil elongated pipe be not enough to by these short pencils very firm fix, while sharpening a pencil with cutter, pencil will slide, unless more than pencil is inserted to extension pipe 2.5cm, the stability of pencil can be relatively good, but can not guarantee that it is completely firm, if the long pencil of 3cm inserts after extension pipe, its pencil that exposes extension pipe outside is very short, cannot implement cutter cuts at all.When pencil only has 3-4cm to grow or more in short-term, is also difficult to roll up and cut with pencil sharpener, when short pencil inserts after various pencil sharpeners, the pencil that exposes outside is substantially all very short, and hand makes not roll up and cut energetically at all; In addition, many pencil sharpeners often can be disconnected by pencil-lead volume, so many people still adopt cutter to sharpen a pencil, so more easily controls, and prevents that pencil-lead from breaking.Just, because of above-mentioned reason, a lot of people can abandon the pencil of 3-4cm, if a people will use pencil for a long time, it accumulates the short pencil quantity of wasting is also larger.From macroscopic view, the people of the so many students in the whole nation and other use pencils is as abandoned the pencil of 3-4cm, and it is quite huge causing so the resources such as timber and some other energy waste.
summary of the inventionthe utility model object: be to provide a kind of special purpose device of cutting short pencil for addressing the above problem.
The technical solution adopted in the utility model is: in a sleeve pipe, be provided with pencil fixture, this fixture bottom is curved splint, this clamping plate bottom flushes with mouth at the bottom of sleeve pipe, these clamping plate are near sleeve pipe one side inwall, and this clamping plate top is connected with clamp holder bottom, and described clamp holder top is vertical configuration, this clamp holder bottom is oblique arcuation, this clamp holder middle part is flexibly connected with horizontal longitudinal axis, and this axle two is connected with sleeve pipe tube wall, and this axle is in middle, sleeve pipe left and right; Described sleeve pipe tube wall is provided with a horizontal horizontal thread pipe, and this screwed pipe is provided with screw with handles, and this screw head contacts with clamp holder top; Described clamp holder top is provided with a horizontal transverse compression spring, and the other end of this spring is connected with sleeve pipe tube wall, and this spring two is overlapped respectively and had minor axis, and this minor axis is connected with sleeve pipe tube wall with clamp holder top respectively; Described screw and spring left and right is corresponding and be on same vertical plane; Described internal surface of sleeve pipe is provided with a positioner, and the distance at the bottom of this positioner and sleeve pipe between mouth is below 1.2cm.
The beneficial effects of the utility model: the utility model can be clamped short pencil firmly, thus be convenient for people to cut these short pencils with cutter etc.When pencil elongated pipe cannot be used ultrashort pencil, the utility model also can be used as the uses such as pencil elongated pipe, ultrashort pencil reliably can be fixed, and makes people can continue to use these ultrashort pencils, thereby capable of saving pencil, reduces the waste of resource etc. as much as possible to greatest extent.The utility model, as long as turn screw can be clamped short pencil, is used very convenient.
accompanying drawing explanationfig. 1 is the utility model application schematic diagram.
the specific embodimentnow by reference to the accompanying drawings the utility model is further described.
As shown in Figure 1,1. screws in figure, 2. clamp holder top, 3. axle, 4. positioner, 5. spring, 6. clamping plate.
In a sleeve pipe, be provided with pencil fixture, this fixture bottom is curved splint 6, these clamping plate 6 bottoms flush with mouth at the bottom of sleeve pipe, these clamping plate 6 are near sleeve pipe one side inwall, and these clamping plate 6 tops are connected with clamp holder bottom, and described clamp holder top 2 is vertical configuration, this clamp holder bottom is oblique arcuation, this clamp holder middle part is flexibly connected with horizontal longitudinal axis 3, and these axle 3 two are connected with sleeve pipe tube wall, and this axle 3 is in middle, sleeve pipe left and right; Described sleeve pipe tube wall is provided with a horizontal horizontal thread pipe, and this screwed pipe is provided with screw with handles 1, and this screw terminal 1 head contacts with clamp holder top 2; Described clamp holder top 2 is provided with a horizontal transverse compression spring 5, and the other end of this spring 5 is connected with sleeve pipe tube wall, and these spring 5 two are overlapped respectively and had minor axis, and this minor axis is connected with sleeve pipe tube wall with clamp holder top 2 respectively; Described screw 1 is corresponding with spring 5 left and right and be on same vertical plane; Described internal surface of sleeve pipe is provided with a positioner 4, and the distance at the bottom of this positioner 4 and sleeve pipe between mouth is below 1.2cm.
Short pencil is inserted in sleeve pipe, and wherein a side of pencil contacts with curved splint 6; Because being provided with positioner 4, make length that short pencil inserts below 1.2cm and can be not oversize; Turn screw 1, make screw 1 head press closer clamp holder top 2 and make clamp holder top 2 (or left side) rotation towards right side, and (or right side) rotation also clamps pencil gradually towards left side by clamp holder bottom, to drive clamping plate 6, along with screwing completely of screw 1, under the drive of clamp holder, clamping plate 6 are also just tightly clamped pencil, pencil is fixed firmly, people are that available cutter sharpens a pencil, because short pencil is fixed firmly, and also can be more convenient as cut these short pencils with pencil sharpener.Cut after pencil, can unclamp screw 1, spring 5 backs down clamp holder top 2 automatically, makes clamp holder and clamping plate 6 unclamp reset, and people just can use after short pencil can being taken off and inserting pencil elongated pipe again.When pencil elongated pipe cannot be used the 2.5cm ultrashort pencil that even 2cm grows, the utility model also can be used as the uses such as pencil elongated pipe, the ultrashort pencil that 2cm is long inserts sleeve pipe 1cm, clamping plate 6 can reliably be fixed it completely, the long pencil of 1cm that sleeve pipe exposes outside can be used after cutting with cutter, thereby capable of saving pencil, reduces the waste of resource etc. as much as possible to greatest extent.
