Abstract
The utility model discloses a kind of paper cutting pen, comprise sleeve pipe, hollow form sleeve pipe one end forms necking down, inside pipe casing is provided with bearing, the mandrel of T-shaped shape is fixed through the inner ring of bearing and fixed block end face, and the fixed block other end is fixed with parallel connecting plate, and circular shear blade is sleeved on the fixed axis between connecting plate, the spring one end being enclosed within mandrel outer wall place is connected with bearing inner race end face, and the other end is connected with fixed block.The utility model is by the axially-movable of mandrel, circular shear blade between connecting plate is leant out the end face of sleeve pipe, cutting out of paper can be realized, pass through rotary core shaft, circular shear blade also can rotate along with mandrel, thus realizes circular shear blade change direction in cutting process.
Description
Technical field
The utility model belongs to the crop tool field of paper, is specifically related to a kind of paper cutting pen.
Background technology
Paper knife is the general designation that a cutter uses class in daily life, in the use of sheet trimming, past we once with fine rule be adjacent to folding after paper edge cut out, also cutting can be carried out by the cutter of blade and so on to paper, and all multimodes and instrument replace by a kind of proprietary paper cutting tool, Here it is paper knife.Paper knife is cut by metal pair paper, and its metal edge is not sharp, but adopts mechanics to engage closely to make paper cut under metal function power.
Paper knife is marked with scale, for the paper of the different size of cutting, also has on some paper knives and vernier scale is housed, and facilitates when cutting and measures size use.The title of paper knife some be again hand papercutter or paper cutting board.
Paper knife when in use, first to the position being about to cutting, will adjust cutting size by moving left and right of the scale on paper knife, then firmly carries out cutting at the uniform velocity downwards by the handle of paper knife.Generally can cutting 4 ~ 5 80g paper.
And current paper knife is difficult to the direction changing cutting in cutting process, round and smooth curve can not be determined on paper.
Summary of the invention
The utility model proposes for solving prior art Problems existing, its objective is and provides a kind of paper cutting pen.
The technical solution of the utility model is: a kind of paper cutting pen, comprise sleeve pipe, hollow form sleeve pipe one end forms necking down, inside pipe casing is provided with bearing, the mandrel of T-shaped shape is fixed through the inner ring of bearing and fixed block end face, and the fixed block other end is fixed with parallel connecting plate, and circular shear blade is sleeved on the fixed axis between connecting plate, the spring one end being enclosed within mandrel outer wall place is connected with bearing inner race end face, and the other end is connected with fixed block.
Described mandrel and bearing inner race matched in clearance.
The utility model is by the axially-movable of mandrel, circular shear blade between connecting plate is leant out the end face of sleeve pipe, cutting out of paper can be realized, pass through rotary core shaft, circular shear blade also can rotate along with mandrel, thus realizes circular shear blade change direction in cutting process.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Wherein:
1 sleeve pipe 2 mandrel
3 bearing 4 fixed blocks
5 connecting plate 6 blades
7 springs.
Detailed description of the invention
Below, with reference to drawings and Examples, the utility model is described in detail:
As shown in Figure 1, a kind of paper cutting pen, comprise sleeve pipe 1, hollow form sleeve pipe 1 one end forms necking down, and sleeve pipe 1 inside is provided with bearing 3, and the mandrel of T-shaped shape 2 is fixed through the inner ring of bearing 3 and fixed block 4 end face, fixed block 4 other end is fixed with parallel connecting plate 5, circular shear blade 6 is sleeved on the fixed axis between connecting plate 5, and spring 7 one end being enclosed within mandrel 2 outer wall place is connected with bearing 3 inner ring end face, and the other end is connected with fixed block 4.
Described mandrel 2 and bearing 3 inner ring matched in clearance.
Described mandrel 2, fixed block 4, by being fixed together through the screw of fixed block 4, are welded with fixed axis between parallel connecting plate 5.
The utility model is by the axially-movable of mandrel, circular shear blade between connecting plate is leant out the end face of sleeve pipe, cutting out of paper can be realized, pass through rotary core shaft, circular shear blade also can rotate along with mandrel, thus realizes circular shear blade change direction in cutting process.
