Abstract

The utility model discloses a hand crank paper shredder comprising a top cover, a lower cover, a fuselage, a litter bin, and two ends of a group of tangent bladed strip knives, a spiral knife and a shovel nose knife. Both ends of a group of tangent bladed strip knives, a spiral knife and a shovel nose knife are separately provided on a baffler. One end of the spiral knife is connected with the handle of the spiral knife through a connecting shaft, and the other end of the spiral knife is equipped with a small output gear which makes the two gears provided on both ends of the two strip knives meshed with each other through the gear driving mechanism and drives the opposite rotation of the two strip knifes. The gear driving mechanism comprises a big output gear which meshes with the small output gear, a small gear provided on the same shaft with the big gear, as well as another small gear which meshes with the small gear; a bearing is provided at both ends of the baffle; an paper inlet provided on the top of the top cover is shorter than the strip knife in the lower cover. The utility model smashes the confidential scrap paper to rice-shaped dust, which greatly enhances the confidential performance, simplifies the structure, reduces the cost; in addition, the utility adopts the hand crank as the driving force, which is not restricted by the electricity and can be widely used in various public places.

Description

Hand shredder

Technical field

The utility model relates to a kind of shredder, and especially a kind of is the shredder of power with hand.

Background technology

Shredder is a kind of modern handle official bussiness apparatus, is used for the processing of secret paper spare.Present shredder is most with the electric shredder, generally all is uses such as relatively large company, office, enterprises and institutions.Application number is " 02217847.3 ", " shredder ", it is power with the motor, and paper is pulverized grain of rice shape by means of the tangent circular knife of the tangent bar shaped cutter of one group of blade and one group of blade and flat blade, its security performance is better, but just can't use under situation about having a power failure.Application number is " 00263049 ", " the hand shredder of fragment shape ", though it is to be power with hand, be not subjected to the restriction of there is electric power or not, but owing to adopt one group of blade dislocation and the tangent circular knife of adjacent edge mutually, this circular knife processing difficulties, mounting process is had relatively high expectations, and has increased cost.

Summary of the invention

The technical problems to be solved in the utility model is to overcome the defective and the deficiency of above-mentioned prior art, for the office equipment field provide a kind of with hand be power, processing. easily manufactured shredder.

The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be: this hand shredder comprises loam cake, lower cover, fuselage and litter decoration, bar shaped cutter that one group of blade is tangent and circular knife, flat blade, its two end is installed on the baffle plate respectively, circular knife one end links to each other with handle by connecting axle, the other end is equipped with output pinion, this output pinion is meshed two gears that are installed in two bar shaped cutter ends by gear drive, and drives two bar shaped cuttves and rotate in opposite directions; Described gear drive comprise the input gear wheel that is meshed with output pinion, with the coaxial mounted pinion of this gear wheel and another pinion of being meshed with this pinion; Described baffle plate two ends are equipped with bearing; The length of paper feed port that is opened in tops is less than the length of bar shaped cutter in the lower cover.

Compared with prior art, advantage of the present utility model is its employing circular knife and combined structure of flat blade, secret waste paper grain of rice official form for filing a lawsuit bits have been ground into, improved security performance greatly, simplify the structure, reduced cost, and employing is a power with hand, be not subjected to the restriction of there is electric power or not, can be widely used in various office spaces.

The specific embodiment

As shown in the figure, this shredder comprises the shell body that loam cake 1, lower cover 7, fuselage 9 and litter decoration are formed.The tangent bar shaped

cutter

3,3 of one group of blade ' and circular knife 8, flat blade 12 is housed in the lower cover, their two ends be installed in baffle plate 2,2 ' on.Baffle plate 2,2 ' two ends bearing is housed, can strengthen rigidity like this, reduce Rotation Noise.Litter decoration just is placed in the fuselage 9 of shredder bottom.Handle 10 is by connecting axle 11 and circular knife 8 one end sockets, the other end of circular knife 8 is equipped with output pinion 6, this pinion 6 and 5 engagements of input gear wheel, be contained in the end of bar shaped cutter 3 with gear wheel 5 coaxial mounted pinions 4, with pinion 4 mutually the pinions 4 of engagement ' be contained in bar shaped cutter 3 ' the end, make bar shaped cutter 3,3 ' blade tangent, and rotate in opposite directions.Flat blade 12 1 end bearings are on knife rest 13, and its blade and circular knife 8 blades are tangent.Paper feed port 14 is arranged on the loam cake 1, and with two bar shaped cuttves 3,3 ' blade corresponding, the length of paper feed port can be stopped because of putting the two end paper jam phenomenons that paper is not just producing like this less than the length of bar shaped cutter in the fuselage.The width of paper feed port preferably is less than or equal to 2mm, and in the time of preventing to use, careless finger stretches into loam cake and injured.

During use, the paper that needs are pulverized is put into paper feed port, rotary handle, drive circular knife, thereby the output pinion that makes circular knife one end rotates and drives the input gear wheel, make and the pinion 4 of gear wheel coaxial rotation and the pinion 4 of bar shaped cutter 3 ' end ' rotation in opposite directions, paper is cut into strip, this strip shredded paper just becomes grain of rice shape through the cutting of circular knife and flat blade again.The utility model adopts circular knife and the combined structure of flat blade, and secret waste paper has been ground into grain of rice official form for filing a lawsuit bits, has improved security performance greatly.
