Embodiment

As shown in Figure 1 and Figure 2, illustrate the specific configuration of the preferred embodiment of cutter 10 1, by a lever 12, one switch with One blade keeps assembly 40 to constitute.

The lever 12 has the two narrow sides 16 in wide face 14 and two, and these narrow sides 16 are continuous curved surfaces, is connected the side in two wide faces 14 Side, makes flat lever 12 to be gripped by hand and uses.Some rib-like structures 18 are arranged in wide face 14 and narrow side 16, lift lever 12 structural strength.

The lever 12 has two ends, is defined as cut end 11 and scraping end 13.The cut end 11 is flat rectangular surfaces, and connection is wide Face 14 forms a combined hole 15 led to inside lever 12 with narrow when 16 is corresponding, and in the end face of cut end 11.The scraping End 13 is the habitat on two narrow sides 16, can encase the root of a wing 17, and support the exsertion part of wing 17 to root out It is adhered to the adhesive tape of article surface or other films (drawing does not show).

The lever 12 also has one to hook hole 19, and the hook hole 19 is close to scraping end 13, secondly end is respectively towards corresponding wide Face 14.By the design for hooking hole 19, lever 12 is set to be suspended on hook.

Two assembling groves 20 are absorbed in corresponding wide face 14 respectively, and these assembling groves 20 are formed at the platform inside lever 12 by one 22 separate.In the elongated hole 24 of the formation of platform 22 one, two irregularly-shaped holes 26 and two clamping grooves 28, these assembling groves 20 and the phase of elongated hole 24 It is logical.

As shown in figure 3, central part of the elongated hole 24 in platform, the one of two short sides be closing, another short side with it is foregoing Combined hole 15 communicate.These irregularly-shaped holes 26 are located at the both sides of elongated hole 24, coordinate two shapes of composition of clamping groove 28 identical but direction phase Anti- elastic component 21.Two protrusions 23 each protrude from the opposite place of two elastic components 21, and the interval S 1 of these protrusions 23 is than long The distance on the long sides of the width W in hole 24 or two is short.These clamping grooves 28 are also in the both sides of elongated hole 24, and two clamping grooves 28 are separated by The distance on ultimate range S2 sides longer than the width W of elongated hole 24 or two is also long.

As Figure 1 and Figure 4, in the present embodiment, described switch is made up of one first toggle 30 and one second toggle 32. First toggle 30 has two parallel columns 34.The shape of second toggle 32 is roughly the same with the first toggle 30, and difference is in In：Post is not bound with, the sliding block 36 for but having a similar rectangle.The toggle 32 of sliding block 36 and second is designed to one, except top Face is formed beyond two recesses 38, also forms one narrow section 31 the one of the short side of sliding block 36 2, and two long sides protrude a salient point respectively 33。

When first, second toggle 30,32 inserts corresponding assembling grove 20, these columns 34 insert corresponding recess 38, Two toggles 30,32 are made to be combined together without separating easily.With narrow section 31 towards combined hole 15, sliding block 36 is set to insert platform In 22 elongated hole 24, two toggles 30,32 are not interfered but to be slidably reciprocated jointly in a closed position with an open position.

In some embodiments, the only one of which assembling grove 20 of lever 12, and also elongated hole 24 has the bottom surface of closing (drawing is not Show).Without the second toggle, but retain the structure of sliding block 36, facilitate the column 34 of the first toggle 30 to be embedded in the recessed of sliding block 36 Portion 38.

The switch of some embodiments, retains the second toggle 32 and sliding block 36, but without the first toggle, is still mountable to lever 12 assembling grove 20, and slidably reciprocated closing, opening two positions.

In Fig. 1, Fig. 2, described blade keeps assembly 40 to be made up of the firm blade 50 of a keeper 42.The holding Part 42 is that plastics constitute a body 44 and an extension 46, and in two passages 48 of formation of body 44.When blade 50 is wrapped by body 44 Cover, these passages 48 show the local blade 52 of blade 50 and blade 54.Each passage 48 is designed to not allow finger to enter Width, prevent blade 54 hurt skin.The wall of the extension 46 and the homonymy of passage 48 accompanies an angle, θ, and θ values are 30 ° ± 5 ° Scope.The described thickness of extension 46 is less than the height of combined hole 15, or the long side of combined hole 15 2 is separated by a distance, it is allowed to Extension 46 freely comes in and goes out the combined hole 15 of lever 12.The extension 46 has two pin 43 and two convex surfaces 45, these pin 43 and sheet Body 44 is at the different ends of extension 46.Each convex surface 45 is formed at the outside of pin 43.

Then Fig. 3, Fig. 4 are seen, the air line distance for defining two convex surfaces 45 is Breadth Maximum W3, not only greater than extension 46 Width, also the distance than the short side of combined hole 15 2 is also long.Therefore, two pin 43 draw close and reduce the straight lines of two convex surfaces 45 away from From extension 46 could enter the combined hole 15 of lever 12, untill body 44 is hampered by the cut end 11 of lever 12.This Carve, two convex surfaces 45 go deep into elongated hole 24, are no longer limited by the short side of combined hole 15, so that two pin 43 reply former according to elastic acting force Shape, related two convex surface 45 enters corresponding clamping groove 28.

At closed position, the common band movable slider 36 of first, second toggle 30,32 stress makes narrow close to cut end 11 Section 31 enters between two pin 43, prevents the air line distance reduction of two convex surfaces 45.Because Breadth Maximum W3 is less than two clamping grooves 28 ultimate range S2, but more than the distance of the short side of combined hole 15 2, so extension 46 can not depart from lever 12, so that lever 12, which combine blade, keeps assembly 40 and is difficult to separate.

Meanwhile, the air line distance of two salient points 33 is considered as Breadth Maximum W2, although less than the width W1 of elongated hole 24, but more than two The interval S 1 of protrusion 23.Therefore, the protrusion 23 blocks corresponding salient point 33, prevents sliding block 36 from moving back the closing toward elongated hole 24 End.Even if first, second toggle 30,32 no longer stress, the sliding block 36 still maintains closed position.

As shown in figure 5, in open position, first, second toggle drives sliding block 36 to move back the blind end toward elongated hole 24, with The space for causing narrow section 31 to leave between two pin 43.Two pin 43 affranchised, detach lever 12 in response to body 44 and are again introduced into knot Close hole 15.Although two convex surfaces 45 are suppressed by the short side of combined hole 15, and related two pin 43 produces deformation, until extension 46 Lever 12 is exited, two pin 43 could be restored.

This moment, two salient points 33 withstand protrusion 23 and moved back toward irregularly-shaped hole 26, cause elastic component 21 to deform phenomenon, simultaneously product Store the active force needed for protrusion 23 playbacks.When first, second toggle 30,32 from open position moves on to closed position, the elasticity The energy of the release accumulation of part 21, restores protrusion 23.
