Description

Light power puncher

Technical field

The utility model relates to the puncher field in the office stationary, is specially a kind of light power puncher.

Background technology

In daily office, often some files and paper punching binding need be in the same place, so that carry, read or deposit.Therefore, puncher is the office stationary commonly used of routine office work, and its quality quality directly has influence on office efficiency.Two drifts of the puncher of 30 or 30 above 80g copy papers of existing bookbinding are being horizontally disposed with of equal in length, and the cutting edge of drift arrives the paper that needs punching simultaneously, in use can relatively require great effort.If laborsaving machine side is set, will cause machine volume bigger.In addition, the cutting edge of drift is flat, and in use the resistance arm between drift and the tailing axle is constant, makes puncher relatively harder in use, is unfavorable for improving office efficiency.

The utility model content

The purpose of this utility model is to have the deficiency of using effort at the above existing puncher, proposes a kind of more compact structure, and is more laborsaving during use, improves the light power puncher of office efficiency.

The utility model is achieved in that light power puncher, comprises face support, drift axle, tailing axle, drift, support and base, and the face support flexibly connects by tailing axle and support, and support is fixed on the base; The drift axle is connected with drift, and the drift axle flexibly connects by chute and the face support that is arranged on the face support, and the drift axle can slide in chute.Chute can make and form the resistance arm that changes between drift axle and the tailing axle: tailing axle immobilizes, the drift axle is with the rotation of face support (machine side) around tailing axle, slide before and after doing in the chute of face support, drive drift and move up and down, the resistance arm between impulsion axle and the tailing axle is also in continuous variation.According to lever principle: power arm (face support) and resistance are constant, and resistance arm is more little, and then the power that puts on the power arm is more little.

Described drift is made up of long drift and short drift, and the length of long drift is longer than short drift, forms structure different in size.The first cut paper of long drift in the process of puncher cut paper, when its cut paper dynamics cross maximum when beginning to diminish short drift begin cut paper again, form the different time differences when utilizing the length of two drifts not coexist cut paper, dynamics avoids reaching simultaneously maximum when making two drift cut papers.

The length of described long drift is than the long 1.5～3mm of short drift.

The cutting edge of described drift is the inclined-plane setting, and similar in appearance to the scissors mouth, cut paper is easier when making its cut paper.

Described cutting edge inclined-plane and drift center line angle are 84 ± 2 °.

The length of utilizing two drifts of the present utility model does not form the different time differences when not coexisting cut paper, and dynamics avoids reaching simultaneously maximum when making two drift cut papers, has reached the labour-saving purpose; The chute of face support makes and forms the resistance arm that changes between drift axle and the tailing axle, and is laborsaving convenient again during use; The cutting edge of drift is for being obliquely installed, and similar in appearance to the scissors mouth, cut paper is easier when making its cut paper.Generally speaking, compared with prior art, the utility model compact conformation uses laborsaving convenience, can improve office efficiency significantly, has broad application prospects.

The specific embodiment

Below in conjunction with accompanying drawing the light power puncher of the utility model is described in detail.

Light power puncher as shown in Figure 1, is made up of assemblies such as comprising face support 1, drift axle 2, tailing axle 3, drift 4, support 5 and base 6.Face support 1 flexibly connects by tailing axle 2 and support 5, and support 5 is fixed on the base 6.Drift axle 2 is connected with drift 4, and drift axle 2 drives drift and does cutting movement up and down.Drift axle 2 flexibly connects with face support 1 by the chute 8 that is arranged on the face support 1.As shown in Figure 2, face support 1 is provided with tailing axle hole 7 and chute 8.Chute 8 is an elongate in shape, and drift axle 2 can be free to slide in chute 8.Chute 8 can be to make to form the resistance arm A that changes between drift axle 2 and the tailing axle 3: tailing axle 3 immobilizes, and drift axle 2 rotates around tailing axle 3 with face support 1 (machine side), slides before and after drift axle 2 is done in the chute 8 of face support 1, drives drift 4 and moves up and down; Resistance arm A between impulsion axle 2 and the tailing axle 3 is also in continuous variation, and the active force situation of puncher is also in continuous variation.According to lever principle: 1 support 1 of power arm face support and resistance are constant, and resistance arm is more little, and then the power that puts on the power arm is more little.Resistance arm changes specific as follows: as shown in Figure 1, and in the original state of using, the resistance arm A maximum between drift axle 2 and the tailing axle 3; As shown in Figure 6, in use, tailing axle 3 immobilizes, and drift 4 slides up and down, and drift axle 2 slides in the chute 8 of face support 1, and drift axle 2 diminishes gradually to the resistance arm A between the tailing axle 3; As shown in Figure 7, after changing to minimum, the resistance arm between the tailing axle 3 do not beginning to become gradually big when drift axle 2.That is to say, when just beginning, drift 4 cut paper resistance arm A maximums, least laborsaving; To move downward the cut paper dynamics big more along with drift 4, and A is more little for resistance arm, and is laborsaving more; When drift 4 cut paper dynamics are maximum, the resistance arm minimum, the most laborsaving; At last, drift 4 cut paper resistance arms are big more not laborsaving more.Rely on the variation of resistance arm, the maximum dynamics of punching work is reduced.

As shown in Figure 5, drift 4 is made up of long drift 4-2 and short drift 4-1, and long drift 4-2 is longer than short drift 4-1, forms structure different in size.In puncher cut paper process, long drift 4-2 elder generation cut paper is crossed maximum when beginning to diminish when its cut paper dynamics, and short drift 4-1 begins cut paper again, form the different time differences when utilizing the length of two drifts not coexist cut paper, dynamics avoids reaching simultaneously maximum when making two drift cut papers.Preferably, long drift is than the long 1.5～3mm of the long drift of short drift.

As shown in Figure 3 and Figure 4, the cutting edge 9 of drift 4 is provided with for the inclined-plane.The inclined-plane of cutting edge 9 is 84 ± 2 ° with drift center line angle, and similar in appearance to the scissors mouth, cut paper is easier during its cut paper.

The utility model compact conformation uses laborsaving convenience, can improve office efficiency significantly, has broad application prospects.
