Abstract

A paper cutter comprises a cutter rest (1), a cutter holder (2) and a blade (3). The blade (3) is fixed on the cutter rest (1), an elongated fixing block (4) for fixing the blade (3) is arranged on a lower end face of the cutter rest (1), the height of the fixing block (4) is smaller than the length of the blade (3), a counter bore (5) is formed in the cutter holder (2), the cutter rest (1) is disposed in the counter bore (5), a groove (6) slidably connected with the fixing block (4) is formed in the bottom of the counter bore (5), a through hole (7) allowing a blade edge of the blade (3) to penetrate is arranged at the bottom of the groove (6), the depth of the through hole (7) is smaller than the distance from the blade edge of the blade (3) to the lower end face of the fixing block, and a reset mechanism is arranged between the lower end face of the cutter rest (1) and the bottom of the counter bore (5). Compared with the prior art, the paper cutter has the advantage of high using safety since during use, the blade is enabled to be exposed by pressing down the cutter rest by hands, and under the action of the reset mechanism, the cutter rest enables the blade edge of the blade to retract after being released by the hands.

Description

Hand papercutter

Technical field

The utility model belongs to office appliance field, particularly relates to a kind of hand papercutter.

Background technology

At present; hand papercutter often can be used in routine office work; the hand papercutter of prior art comprises knife rest, tool rest and blade; knife rest is connected on tool rest, and blade is fixed on knife rest on hand, but because the cutting edge of blade all exposes; in use; cutting edge incised wound user and other personnel, or scratch desktop or other object, therefore the security of using is poor.

Utility model content

The utility model provides a kind of safety in utilization good hand papercutter for above problem.

The utility model overcomes the above problems technical scheme used: a kind of hand papercutter with following structure is provided, it comprises knife rest, tool rest and blade, described blade is fixed on knife rest, described knife rest lower surface be provided with strip for the fixing fixed block of blade, the height of described fixed block is less than the length of blade, described tool rest is provided with counterbore, described knife rest is positioned at counterbore, described counterbore bottom is provided with the groove being slidably connected with fixed block, described bottom portion of groove is provided with the through hole passing for knife-blade, described via depth is less than knife-blade to the distance between fixed block lower surface, between described knife rest lower surface and counterbore bottom, be provided with resetting-mechanism.

Adopt after above structure, compared with prior art, the utility model is because counterbore bottom is provided with the groove being slidably connected with fixed block, bottom portion of groove is provided with the through hole passing for knife-blade, via depth is less than knife-blade to the distance between fixed block lower surface, and be provided with resetting-mechanism between knife rest lower surface and counterbore bottom, while using, knife rest is pressed down with hand, the blade of blade is exposed from the bottom surface of tool rest, now can carry out follow-up cutting work, and after hand is decontroled, knife rest is under the effect of resetting-mechanism, the blade of blade is retracted, the no longer exposed outside at tool rest of blade, this also just there will not be cutting edge incised wound user and other personnel, or scratch the situation of desktop or other object, safety in utilization is higher.Therefore the good feature of the utility model safety in utilization.

As improvement, on the side of described fixed block, be equipped with square stopper slot, the sidewall of described groove is provided with and coordinates spacing limited block with stopper slot, described limited block and stopper slot are slidably connected, the both sides of described counterbore bottom groove are equipped with the strip through-hole extending along groove length direction, the combination of limited block and stopper slot, the sliding scale of knife rest is limited, when resetting-mechanism resets, the situation that there will not be knife rest and tool rest to throw off, increases stability in use of the present utility model; The effect of guiding has been played again in simultaneously limited block and the combination of stopper slot, and direction and stability when fixed block is slided are better, prevents fixed block slip hour offset and the situation generation that causes fixed block to block, makes the slip of fixed block more smooth and easy; Moreover after strip through-hole arranges, make recess sidewall described in limited block all have the ability of strain, and while assembling, make limited block be easier to clamping and put in place, and then improve efficiency of assembling, reduce production costs.

As further improvement, described resetting-mechanism is shell fragment, described shell fragment is connected on knife rest lower surface, and shell fragment and knife rest are integral type structure, this shell fragment is simple in structure, and can with knife rest integrated injection molding, preparation cost is lower, omit the installation procedure of shell fragment simultaneously, further improved production efficiency of the present utility model.

As further improving, the lower surface of described fixed block is connected with the holder of fixed blade, after holder arranges again, after blade rust, holder is pulled down, changed subsequently new blade and again by holder clamping, make the replacing of blade convenient.

As shown in the figure: 1, knife rest, 2, tool rest, 3, blade, 4, fixed block, 5, counterbore, 6, groove, 7, through hole, 8, stopper slot, 9, limited block, 10, strip through-hole, 11, shell fragment, 12, holder.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described further.

As Fig. 1, a kind of hand papercutter shown in Fig. 2 and Fig. 3, it comprises knife rest 1, tool rest 2 and blade 3, described blade 3 is fixed on knife rest 1, described knife rest 1 lower surface be provided with strip for the fixing fixed block 4 of blade 3, the height of described fixed block 4 is less than the length of blade 3, described tool rest 2 is provided with counterbore 5, described knife rest 1 is positioned at counterbore 5, described counterbore 5 bottoms are provided with the groove 6 being slidably connected with fixed block 4, described groove 6 bottoms are provided with the through hole 7 passing for blade 3 blades, described through hole 7 degree of depth are less than blade 3 blades to the distance between fixed block 4 lower surfaces, between described knife rest 1 lower surface and counterbore 5 bottoms, be provided with resetting-mechanism, blade is greater than to the distance between fixed block 4 lower surfaces the summation that through hole 7 degree of depth add upper groove 6 degree of depth.

On the side of described fixed block 4, be equipped with square stopper slot 8, the sidewall of described groove 6 is provided with stopper slot 8 and coordinates spacing limited block 9, described limited block 9 is slidably connected with stopper slot 8, and the both sides of described counterbore 5 bottom grooves 6 are equipped with the strip through-hole 10 extending along groove 6 length directions.
