Description

The file perforating device

Technical field

The present invention relates to a kind of file puncher, particularly a kind of motor of single rotation direction that uses can make cutter finish the file puncher of a complete punching action of punching and answer location.

Background technology

Organigram shown in Fig. 1 (a), existing file puncher 11, be under the effect of a fulcrum formation 111, allowing strength Fx that the user executed drive cutter 112 punches on file, and, make and just can reach needed punching strength F with lower thrust by long force arm 113.Therefore, in order to obtain the strength F that punches, the strength that we must provide is Fx=F*a/b.

Please refer to Fig. 1 (b) again, its be with above-mentioned lever construction the further organigram from dynamic puncher 12 of exploitation, add one group of gear 122 at force arm 121 1 ends, when driving mechanism 123 transmits as shown in the drawing clockwise direction and rotates, to drive cutter 125 under the effect of fulcrum formation 124 realizes file is punched downwards, after cutter 125 reached the bottom, driving mechanism 123 was again counterclockwise to rotate the location of cutter 125 being taken back the top.Such driving mechanism is very directly will originally make manually that the reciprocating action of force arm is converted to the reciprocating action of own power mechanism, allows the more convenient operation of user.

But in the said structure, driving mechanism 123 must have towards the ability of two directions running, make that this driving mechanism 123 and the cost of corresponding controlling organization (not shown) are higher, and the running of two directions also causes the relation of driving mechanism 123 because of stopping operating and recovering again to rotate, except making driving force that the situation of waste take place, also make driving mechanism 123 life-span thereby be affected.And shown in Fig. 1 (c), a kind of newer file puncher 13 (correlation technique sees also United States Patent (USP) 4987811) is developed, this mechanism utilizes lever principle, but in the output of the power of driving mechanism 131, then change and adopt a bent axle 1311 and drive force arm 132 and carry out reciprocating action, bent axle 1311 is when least significant end, the location up that cutter 133 is relative, and when bent axle 1311 turns round to peak, cutter 133 moves down and punches, and will get back to the location of top along with the cutter that remains in operation of bent axle.131 needs one-directional rotation of whole process driving mechanism can be finished, solved before stop operating and recover to rotate again problem.Yet in the application that bent axle and lever merge,, cause the parts fault because of gap enlargement easily after use a period of time because of a large amount of frictions that increased newly between bent axle and lever are worn and torn.
