Abstract

The utility model discloses a secateur, which is composed of two shear blades provided with handles and axially connected with each other in a cross mode. On the contacted shearing surfaces of the two crossed shear blades, arris strips called reinforcing ribs are longitudinally and concavely arranged on the shearing surfaces and are convex to the corresponding surfaces. Each of the arris strips can be in the shape of a straight line or an arc line or a curved line according to the shape of the secateur. When the secateur of the utility model is used for shearing and trimming thick and hard twigs and branches, the shearing force on the shear blades can be largely enhanced, the shear blades can not be twisted and deformed, the thickness of edge steel of the shear blades can be thinned, and the material is saved; thus, the manufacturing cost is reduced, and the utility model is portable and sharp in use.

Description

Shrub and hedge trimmer

Technical field

The utility model relates to a kind of garden instrument, specifically a kind of shrub and hedge trimmer of pruning arrangement flower tree branches and leaves.

Background technology

The general at present shrub and hedge trimmer that using, be that shear blade by two band shear shanks intersects to be coupling and forms, have at least one to have sharp blade in two shear blades, for ease of cut operation, increase shrub and hedge trimmer and shear the shearing force of thick and stiff branch fork fork, shrub and hedge trimmer are often put long shear shank or augmentor, such as Chinese patent application number 022154094 disclosed scalable sleeve shear shank, the augmentor of the Chinese patent application number long moment twisting of 022154116 disclosed shear shank shear blade, after shearing force strengthens, for making shear blade can bear the bigger force intensity that is subjected to, shear blade must be thickeied, and widens, and is subjected to force intensity and torsional deformation in order to avoid exceed, but widen, the shear blade of thickening is when the grinding sword, the entrance angle of blade strengthens, and blade is reduced the cut-out power that is sheared the thing branch, and the shear blade of widening thickening simultaneously makes the shrub and hedge trimmer heaviness, effort inconvenience during use, the cost of making shrub and hedge trimmer increases.

Summary of the invention

The purpose of this utility model is to overcome deficiency of the prior art, and providing a kind of does not need to thicken, widen the shrub and hedge trimmer shear blade and just can increase substantially the shrub and hedge trimmer that shear blade bears shearing, thus make shrub and hedge trimmer light and handy, save cost of manufacture.

For reaching above-mentioned purpose, shrub and hedge trimmer of the present utility model are intersected to be coupling by the shear blade of two band handles and form, on the shear surface of shear blade cross-shear contact, and the rib that is commonly called as reinforcement that vertical depression is arranged and protrude to the shear surface opposite face.The shape that rib is looked shear blade linearly, lonely line, curve-like.

The beneficial effects of the utility model are: 1, shear blade bears intensity of shear and increases substantially, can torsional deformation when shearing thick and stiff branch.2, can reduce the thickness and the width of shear blade, make shrub and hedge trimmer lighter sharp.3, can reduce high-speed steel materials, the reduction cost of manufacture of making shear blade.

Description of drawings

Fig. 1 is a structure front view of the present utility model.

Fig. 2, Fig. 3 are the utility model structure front views of two kinds of embodiment in addition.

Embodiment

The utility model is described in further detail in conjunction with the embodiments with reference to the accompanying drawings.

Shown in Figure 1, shrub and hedge trimmer are by shear blade 1,2 intersections are coupling and form, in order to alleviate the weight of shrub and hedge trimmer, reduce material cost, it is beautiful to increase outward appearance, the fixing shaft-like shear shank 3 of high-strength colour plastics on the short metal shears handle of a knife under the shrub and hedge trimmer intersecting axle, 4, to prolong the handle of cutting of shrub and hedge trimmer, omit the length of the shaft-like shear shank of plastics among Fig. 1, the actual length ratio at axis two ends that uses can be 1: 2～12, the metal shears blade of shrub and hedge trimmer heats to stamp out in mould when blank forming and is positioned at shear blade 1, be commonly called as the rib of vertical one side depression one side protrusion of reinforcement on the 2 wide skew centre positions, shear blade base substrate with rib is after the thermal treatment of grinding blade, two shear blades intersection is coupling, on short metal shears handle of a knife, the shaft-like shear shank of adjunction highstrenghtpiston, Fig. 2, the blade of its shear blade shown in Figure 3 is arc shaped and curve-like, the base substrate heating of shear blade, the mould punch line is camber line and curve-like during the mould punching press, grinding blade intersection is coupling, adjunction high-strength colour plastics shear shank on short metal shears handle of a knife, or adjunction sleeve rod-pulling type shear shank, or the augmentor of the long moment twisting of adjunction shear shank shear blade.

Claims

1, a kind of shrub and hedge trimmer are intersected to be coupling by the shear blade of two band handles and form, and it is characterized in that: on the shear surface of shear blade cross-shear contact, and the rib that is commonly called as reinforcement that vertical depression is arranged and protrude to the shear surface opposite face.

2, shrub and hedge trimmer as claimed in claim 1 is characterized in that: rib is a linearity.

3, shrub and hedge trimmer as claimed in claim 1 is characterized in that, rib is an arc shaped.
