Description

The structure-improved of adjustable puncher

Technical field

The utility model relates to a kind of puncher, particularly a kind of adjustable puncher structure.

Background technology

General commonly used puncher comprises: pedestal, two are arranged at perforation on the pedestal, two and are arranged on the pedestal and the tool rest corresponding with perforation and be articulated in the pedestal both sides and the corresponding pressing plate that pushes up the cutter of each tool rest of pulling; When under pressing plate, being pressed on the cutter top on the tool rest, the perforation that makes cutter to correspondence is pressed down mobile, thereby can on paper, extrude the position, hole of two fixed ranges.

Because traditional puncher only can extrude the position, hole of two fixed ranges, when the user need extrude position, three holes on paper, must be after extruding position, two holes, utilize the cutter of a tool rest on paper, to extrude another position, hole more again, yet the spacing after the 3rd position, hole extrudes will be different with previous two hole column pitch that extrude earlier, therefore needs that usually can't realistic utilization.In this case, the user must buy the puncher that can extrude position, three holes again, and thus, different holes figure place will have a kind of puncher, not only need to consume additional expense, and also easy-to-collection not of numerous puncheres.

The utility model content

At the above-mentioned problems in the prior art, the utility model proposes a kind of structure-improved of adjustable puncher, include: pedestal, its both sides are provided with first and second perforation, the the 3rd and the 4th perforation that has different spacing between described first and second perforation, contiguous described third and fourth perforation place is provided with two first location divisions and two second location divisions, described pedestal both sides are provided with two fixedly tool rests, described two fixedly tool rest correspond respectively to described first and second the perforation, described two fixedly the outside of tool rest have side plate respectively; Movable tool rest, it is articulated in described pedestal, and at described two fixedly between the tool rest, one side of described movable tool rest contacts with one of described first location division, and the locating hole of described movable tool rest bottom is positioned on one of described second location division, when described movable tool rest was positioned at one of described first and second location division, it was corresponding to the described the 3rd or the 4th perforation; And pressing plate, be articulated between described two side plates, and be positioned at described two fixedly tool rest and described movable tool rest tops.After above-mentioned movable tool rest is adjusted pitch-row, pressing plate is pressed down, can on paper, extrude position, hole as required with constant spacing.

The beneficial effects of the utility model are, by puncher is designed again, make the user can adjust the pitch-row of puncher voluntarily, thereby can extrude the position, hole with constant spacing as required on paper.
