Abstract

The utility model relates to a pair of gardening scissors with a positioning device. The utility model is provided with a positioning device on a handle of a blade, wherein the positioning device comprises a stop bar which is arranged at the front end of the handle of the blade and laterally extends, and the stop bar with elasticity moves in a toggling sheet. The toggling sheet with an n-shaped section is clamped between the front side and the rear side of the handle of the blade, and the opening end is inward; a pivot of a pivot shaft can be toggled up and down; two concave slots are arranged in the toggling sheet, and the stop bar is clamped into the position where the toggling sheet is fixed. The opening end of the toggling sheet is provided with a shaft bar which is correspondingly embedded into two gap holes at the bottom ends of two blades, so that the two blades are clamp in a closed state, and the effective positioning is realized.

Description

Gardening scissors with positioning device

The utility model relates to a kind of orchard shears with keeper.

The orchard shears of prior art, see also shown in Figure 1, with a catch 1 bolt-lock on following blade 2 handles 201, and establish a breach 301 in upper knife edge 3 tail end relevant position places, when folding scissors, embed breach 301, the safety of guaranteeing to receive and keep to support that upper knife edge 3 can not open by catch 1.Again referring to shown in Figure 2, should fixingly arrest the button structure, be fixed on the handle 201, make its deflection arbitrarily because of catch 1 is made of metal with bolt locking pivot, so must bestow the thrust that is enough to promote catch 1 when switching, therefore operation is difficult quite painstakingly when bringing into use; Also because so, bolt can reduce gradually to the coupling mechanism force of catch 1 in use for some time, relative catch 1 is kept out strength and is reduced, cause that the effect that supports greatly reduces to upper knife edge 3, can't effectively control the folding of blade, have again, when the bolt location of locking catch 1 is loosening, catch 1 is because of without any location structure, the free deflection state in the pruning process, cause false touch easily, cause blade to block motionlessly in the action suddenly cutting to close, the application of force is used and to be had some setbacks, have a strong impact on function of use, have much room for improvement.

The purpose of this utility model is to provide a kind of orchard shears with keeper.

The purpose of this utility model is to realize like this, a kind of orchard shears with keeper promptly is provided, it establishes keeper on two blade sheets intersect a blade sheet shank forward end of assembling scissors, this keeper comprises is located at a blade sheet shank forward end, the pin that extends laterally, it has suitable elasticity, and it is movable in a sliding piece, this sliding piece cutaway view is JiongZi Xing, be located in blade sheet shank front and back side, its openend inwardly, the mat pivot can be stirred up and down, nearly open end is established an axostylus axostyle, and corresponding embedding two blade sheet bottom parts are offered two scarce hole blocking two blade sheets and are the tight state that closes, and it seals distolateral two chases of establishing, when this pin snaps in the position of fixing sliding piece, realize location conscientiously.

The advantage of the orchard shears of the utility model band keeper is that its keeper can fix the location conscientiously with the sword sheet, can fold the sword sheet safely and effectively, and practicality is good.

Below in conjunction with accompanying drawing, embodiment of the present utility model is described, wherein:

Fig. 1 is a prior art orchard shears open configuration schematic perspective view;

Fig. 2 is a prior art orchard shears collapse state schematic perspective view;

Fig. 3 is the utility model orchard shears schematic perspective view;

Fig. 4 A, 4B, 4C are the utility model orchard shears operation chart.

See also shown in Figure 3, it is the orchard shears of the utility model band keeper, and it comprises that a cutter cuts 10, is the winding of intersecting axle pivot with its two blades sheet 11,12 and forms, its front end blade position can supply the usefulness of topiary, and the rear end articulates shank 13,14 for the staff gripping; In two blade sheets, 11,12 bottom center positions, offer downwards respectively and lack hole 111,121, close when tight when two blade sheets 11,12 are involutory, this two scarce hole 111,121 aligns with one heart, and wherein a bit of position of blade sheet 11 shanks, 13 front ends dwindles thickness, has caused difference in height and formed a bent oblique line shape to keep out edge, this is kept out edge and is divided into front and rear sections, leading portion 131a becomes horizontal back segment 131b then to be tilted to down approximately, keeps out position, edge the place ahead in this, and keeper 15 is set;

This keeper 15 comprises that being located at these blade sheet 11 shanks 13 front ends is the pin 151 that extends laterally, and the sliding piece 152 of stirring this pin 151 up and down; This pin 151 and shank 13 folder predetermined angulars, its position, top is circular-arc, makes with elastomeric material to have suitable elasticity, and is when upwards being stretched and compressing downwards, movable in sliding piece 152; This sliding piece 152 is that a sectional plane is JiongZi Xing, face as same fan-shaped lamellar body, be located in cutter in the double team mode and cut 10 shanks, 13 front and back sides, with its openend 152 ' inwardly, the center by 153 pivots of a pivot on shank 13, can be stirred up and down, it seals distolateral 152 " in have two chases 154; 155; can snap in the location for position, pin 151 top; fix sliding piece 152 location status; an axostylus axostyle 156 is established at sliding piece 152 near openend 152 ' positions; corresponding embedding two blade sheets 11, the two scarce holes 111 that 12 bottom parts are set, in 121, blocking two blade sheets 11,12 are the tight state that closes;

When the user grips above-mentioned cutter when cutting 10 2 shanks 13,14, earlier upwards promote sliding piece 152 with thumb, make this pin 151 snap in the sliding piece 152 in below chase 155 location, this moment, sliding piece 152 openends, 152 ' axostylus axostyles 156 " disengaging " two blade sheets 11,12 bottoms lacked hole 111,121, two blade sheets 11,12 are free state, shown in Fig. 4 A, and sliding piece 152 is horizontal against keeping out edge leading portion 131a position, any position-limiting action that do not recur, the application of force is used two blade sheets, 11,12 topiaries relatively; When desiring to pack up orchard shears 10 when finishing using, promptly grip and merge two blade sheets 11,12 this moments, its two bottom two lacked hole 111,121 align with one heart, shown in Fig. 4 B, it is downward to promote sliding piece 152 with thumb again, be resisted against and keep out edge back segment 131b position, can be again to lower swing, and pin 151 moves to when being stuck in sliding piece 152 another chases 154 of interior top, embed two blade sheets 11 with its axostylus axostyle 156 simultaneously, 12 lack hole 111, in 121, two blade sheets 11,12 keep closing tight collapse state, to guarantee to fold blade sheet 11,12 in safe condition, shown in Fig. 4 C, fold in the screens action at it, comprise two road security perimeters in this keeper sliding piece: one is that pin 151 snaps in chase 151.Second it be that axostylus axostyle 156 embeds in two blade sheets, 11, the 12 scarce holes 111,121, and the screens action puts in place, overcomes the shortcoming of prior art scissors effectively, and practicality is good.
