Description

Mono-hole punch

The present invention relates to a mono-hole punch.It has a base plate and two to be contained in to be used for fixing on the base plate one with by the bearing supporting of spring reset power and can rotating pressure handle.Pressure handle affacts on the pierce punch that moves both vertically, and constitutes a paper feeding mouth between base plate and bearing.Owing to a crank throw is arranged above the base plate, thereby constitutes the stop of paper feeding mouth.Be provided with the punching mark that centers in the pressure handle front.

Mostly be the diplopore puncher in actual applications.In order to punch arbitrarily, for example, get the hole of 4 or 6 multiples, have special puncher and have the adjustable multiple hole puncher of spacing.But, these puncheres are more expensive relatively.

Task of the present invention is, designs a kind of mono-hole punch that is well known, and makes it accurately get any amount of hole according to desirable spacing.

Solution of the present invention is: an additional positioner that is used for fixing any hole is set.The functional areas of this positioner are in the front end or the paper feeding port area of paper feeding mouth.Can be designed to the fork-shaped ruler-like to positioner, it can move between two bearings, perhaps, it is limited in the pressure handle front, at this moment, can make fork chi in location have one after the elevation angle, just can pitch chi to the location by this structure and be fixed on the front of pressure handle.

In structure of the present invention, location fork is to be made by a transparent material, and two parallel fork pin are arranged, and they and a flat pieces are connected as a single entity, and also can design the alice of rounding up at the free end of flat pieces.Embodying a kind of good project organization of the present invention is, the location fork is provided with the location link stopper, and it matches with corresponding locating slot.

Relevant structural applications of the present invention has all been mentioned in all claims.

Describe embodiments of the invention in detail by following all accompanying drawings:

Fig. 1 represents the mono-hole punch identical with material object on the size, and its location fork has been pushed in the machine;

Fig. 2 represents the location fork identical with full size;

The same Fig. 2 of Fig. 3, but the location fork has alice;

Fig. 4 represents to be contained in the location fork of a kind of modified structure on the mono-hole punch identical with full size, and the residing position of fork, location;

Fig. 5 represents new paper that has been equipped with the sample paper in hole and has also needed to hit the person seeing from vertical view and the residing position of mono-hole punch;

The same Fig. 1 of Fig. 6, but have the adjustable journey hoop of deciding;

Fig. 7 represents the identical journey hoop shape of deciding with full size;

Fig. 8 represents identical with full size, and forms holistic location fork with outer stopper; And

The same Fig. 8 of Fig. 9, but stop is positioned at the fork pin.

Known mono-hole punch has a base plate 1 and two bearings 2 that are fixed on the base plate 1, because reasons in structure, two bearings that are positioned on the base plate are made an integral body.Bearing 2 is used for accepting a pressure handle 3 that supports pivotally by spring reset power, and this pressure handle affacts on the pierce punch that moves both vertically.Between base plate 1 and bearing 2, constitute a paper feeding mouth 4.By the last crank throw of base plate 1, this paper feeding mouth 4 has a back stop 5.

In order accurately to make a call to a hole, on this mono-hole punch, establish the positioner of location fork 6 shapes in a certain precalculated position of a piece of paper.According to shown in Figure 1, this location fork 6 can move between two bearings 2, perhaps according to shown in Figure 4, can make it be limited in the front end position of pressure handle 3 regularly by a back alice 10.As shown in Figure 4, these location fork 6 free ends in 2 its fronts are closed to constitute a slotted hole 11.

The location fork 6 that moves between two bearings 2 is preferably made by a material transparent, two parallel legs 7 are arranged and fuses with flat pieces 8.In order to improve operation, the free end that is positioned at flat pieces 8 forms a tip-tilted coupling limit 9.Just as can being derived by Fig. 2, the ratio of the length of leg 7 and flat pieces 8 was near 3: 1, and this moment, its leg 7 had the same intensity with flat pieces 9.

The paper 14 of need punchings is placed the bottom of 13 the sample paper 12 of having openning hole with staggering, need the district of punching should place the periphery of sample paper 12.In when punching, the location fork 6 on the mono-hole punch be placed on existing sample hole 13 above, so just can accurately get new hole.

Because usually need to change the distance of trimming in practice to the hole, i.e. pitch-row, therefore, what must be able to change the paper that is perforated puts the depth degree.The modified structure that various paper shown in Fig. 6-9 are put into the degree of depth all can satisfy above-mentioned purpose.

According to the present invention, be respectively equipped with an adjustable stop 15 and adjustable decide journey hoop 16.Shown in Fig. 8 and 9, stop 15 is made an integral body with location fork 6.This stop 15 is by shown in Figure 8, and this stop 15 is positioned at location 6 liang of outer side edges of fork and is; According to shown in Figure 9, stop 15 is the inboards that are positioned at the terminal of slotted hole and location fork 6.Stop 15 has down a flange respectively.In the stop structure of this location, be positioned on the length of mobile distance of base plate 1 and be respectively equipped with a grooving or groove, match with flange with this.

Fig. 6 and 7 is another kind of organization plans of adjustable stop.Under the internal stress effect, decide journey hoop 16 and can be pulled on the bearing 2.Should decide journey hoop 16 and see type as U-from vertical view.The end that constitutes two flanges of location stop curves the right angle.In order to change the mobility of deciding journey hoop 16, make crosspiece be designed to hand.Can reach on the bearing 2 in order to make towards deciding the internal stress that journey hoop 16 moves, crosspiece is risen by two flanges and taperedly each other dwindles gradually, thereby it will open when pushing to, so, will between the exterior rim of the flange of deciding journey hoop 16 and bearing 2, form a kind of friction and connect.
