Abstract

The utility model relates to an improved blade trimmer for shutter. The ends of the upper and lower trimming seats are respectively sheathed with an elastic element; a connector pin is pivoted on the elastic element through inserting; two blades tangency with the upper and lower parts with corresponding cuts are provided by the upper and lower trimming seats. Thus, the main body of the blade trimmer is formed. A measuring device which is capable of pivoting, spacing, shifting and regulating is connected with the lower part of the lower trimming seat.

Description

Improved shutter blade trimmer

The utility model is about the terminal blade of louver window trimmer of pruning usefulness of a kind of blade of louver window, and its improved design is particularly repaiied below this trimmer main body and cut seat and measurement mechanism gage pivot joint, can make rotation and relative shift movement; The upper and lower Cutter apron of trimmer main body in addition can cooperate the cutoff edge of the correspondence of single otch or two incision; This trimmer can be pruned linear measure longimetry, and the gage revolution is hidden in the bottom with convenient harvesting, also can adapt to the pruning of two kinds of different fabric width blades.

A kind of improvement of blade of louver window trimmer, mainly provide blade to shear the trimmer of trimming usefulness, particularly can reach expection effective, accurate, simple and easy and apace and prune length, can be shared for two kinds of different fabric width size blades, and its gage can turn round again and be hidden in blade trimmer bottom, helps the customer and carries, uses.

Past is in order to shear the trimmer (referring to shown in Figure 7) of trimming blade of louver window end, its structure is on two upper and

lower pruning seats

1,2, be respectively installed with the upper and lower cutoff edge 3,4 of repairing, their corresponding up and down settings,

prune seat

1,2 tail ends two and articulate, make this two

prunings seat

1,2 can drive upper and lower cutoff edge 3,4 upper and lower the doing relatively reciprocating motion of repairing, make upper and lower shearing knife edge 3,4 with a pivot pin 5, form the shear knife as scissors, cut the blade of louver window end to repair.

The blade trimmer of this class formation is repaiied the intended purposes and the effect of cutting blade though can reach, and in the use, still has following shortcoming:

1. no any aided measurement device on the trimmer, the essential mark of on blade, making the expection sheared length earlier of user, and then blade placed between the sheared edge, whether arrive desired location with range estimation, remake shearing, cause the inconvenience in the use.

2. though make to have the shearing mark on the blade, align because of adopting the range estimation mode; Therefore, long or not enough incorrect shearing takes place in regular meeting.

3. sun blind of using for the household, the most frequently used person of its blade have 2.5 centimeters with the wide two kinds of sizes of 1.5 father-in-law, and trimmer only be the shearing knife edge of single size, so that can't be fit to that both are general, forms the inconvenience in the use.

So this kind blade trimmer, disadvantage are not have measurement mechanism, moreover be exactly the cutting blade mouth of single size, if a measurement mechanism is provided, and the cutting blade mouth that the cutoff edge of trimmer is designed to have two kinds of sizes, problem can be readily solved.

Main purpose of the present utility model is to provide a kind of improved blade of louver window trimmer that scalable adjustment gage is arranged, and makes blade can directly lean shearing, can correctly reach the expection sheared length.

A purpose more of the present utility model is to provide a kind of upper and lower shearing knife edge of trimmer, and it has recessed otch, the protruding incisxal edges of two kinds of different sizes, is beneficial to the shearing trimming of two kinds of blades that the household uses always.

Shown in Fig. 1,2 is a kind of improved blade of louver window trimmer, upper and lower the repairing of this trimmer cut suit one flexible member 23 between

seat

21,22 ends, insert with a latch 24 again and articulate, cut seat and upper and

lower cutoff edge

25,26 etc. is housed on 21,22 upper and lower repairing, constitute a main body 20, and under main body 20, repair and cut seat 22 bottoms in conjunction with a measurement mechanism 30 that can pivot and be shifted and adjust; Wherein,

Upper cutter sword 25 is plates, and middle body is provided with two location convex bodys 251, can repair to snap in the locating hole when cutting on the seat 21 on inserting and fix, and its side is concaved with the recessed otch 252,253 of two sizes;

Incision blade 26, also be plates, middle body is provided with two location convex bodys 261, can under inserting, repair to snap in the locating hole when cutting on the seat 22 and fix, its side convexes with the protruding incisxal edge 262,263 of two sizes, make this protruding incisxal edge 262,263 can with 252,253 corresponding the suiting of recessed otch of upper cutter sword 25;

Measurement mechanism 30, mainly contain the L type gage of forming with ruler 311 and right angle block body 312 31, its ruler 311 central authorities are provided with a microscler guide groove 313, are provided with the convex body 318 of equi-spaced apart in microscler guide groove 313 both sides, this convex body 318 can with under repair cut the seat the mutual chimeric location of set embeded slot, 22 bottoms; And 312 of bottom proximal end place and right angle block bodies have can be chimeric mutually spacing two positive stops 314 and microscler guide groove 315, and the locking of borrowing retaining element 316, so that right angle block body 312 can be made the line shifting stretching motion with ruler 311, and being provided with size scale in microscler guide groove 313 both sides of ruler 311, block body 312 ends in right angle inwardly convex with retaining edge 317; In addition between incision seat 22 and ruler 311, pivot 33 suits one a tension elastomeric element (the taper tension spring is best) 34, pass the through hole 221 on the incision seat 22 and the microscler guide groove 313 of ruler 311, relend a buckling piece 35 and be fastened on pivot 33 ends, whole blade trimmer 20 and this measurement mechanism 30 can be pivoted, and make blade trimmer 20 can on measurement mechanism 30, do the line shifting adjusting.

When the utility model uses, can make upper and lower repairing

cut seat

21,22 relative motions by trimmer main body 20, and make the recessed otch 252,253 and protruding 262,263 relative suiting of incisxal edge of upper and

lower cutoff edge

25,26, shear with blade different fabric widths; And can conjunction measuring device 30 make the ruler 311 relative displacements of trimmer main body 20 and measurement mechanism 30, and locating after the displacement relatively, prune (as shown in Figure 3) blade 40 is made fixed length, as if the size adjusting of being done at the trimmer main body 20 and the ruler 311 of measurement mechanism 30, can not reach required size, then can cooperate the telescopic adjustment (as shown in Figure 4) between ruler 311 and the right angle block body 312, to meet demand; If when not using, 20 rotations of trimmer main body can be overlapped with ruler 311, and the retaining edge that makes its end be embedded in right angle block body 312 blocks for 317 times, with reduced volume (as shown in Figure 6).Therefore, the utility model following advantage of having got everything ready at least:

1. can provide simultaneously the blade of two kinds of different fabric width sizes to shear trimming.

2. can be by gage to blade as the fixed length location that bridges, shear and simplify the operation to reach correct size.

3. when small size is pruned, the terminal right angle block body that connects of responsible ruler leans and finely tunes, and visual the repairing that can get rid of traditional small size cut.

4. ruler can hidden be affixed on down bar and cut the seat bottom, cuts function (as shown in Figure 5) except keeping repairing of its endless, and if the terminal right angle block body that embeds the ruler end of main body, can possess less integral outer appearance and convenient harvesting (as shown in Figure 6).
