Abstract
The utility model relates to a pair of single-edge type scissors for pruning, which is characterized in that a knife blade 3 is adopted. Handles 1, 2 are made of plastic. The handle 1 and a clamping body are formed into integration. The handle 2 is connected with the handle part of the knife blade 3 by a connecting rod 4. Compared with the prior art, the utility model has the advantages of laborsaving operation, portability, long service life, etc. Compared with similar products, the weight of the utility model is lighter by more than 60%.
Description
The utility model relates to the shrub and hedge trimmer of a kind of flowers or fruit tree, particularly single-blade formula shrub and hedge trimmer.
Shrub and hedge trimmer commonly used contain two blades, its blade can be sheared mutually, each blade and its handle are one, the turning point of each blade connects with a rivet as fulcrum, adopt the compression spring to connect between two handles, this compression spring opens two blades and handle automatically, and blade is sheared limb in the time of firmly.
The defective of above-mentioned twolip formula shrub and hedge trimmer is:
1. relying on during the application of force two blades to shear mutually cuts off limb, once fail to cut off as if the application of force for thicker limb, need execute opposite power two blades are opened, continue to must be noted that when the application of force is sheared that aiming at former joint-cutting shears again, cut again then waste physical if depart from former joint-cutting; Compression spring situation just unloaded and that cut off just can make blade open, and the spring force deficiency has only and executes opposite force artificially and just opened so that blade opens constantly the time cutting.Therefore shear repeatedly just can cut off the time at needs, some is to have done idle work in the muscle power that the operator consumes.
2. all parts are all made with metal material, and are comparatively heavy, operate and carry comparatively hard.
The purpose of this utility model provides a kind of single-blade formula shrub and hedge trimmer of in light weight, rapid operation, and its handle adopts plastics to make, and weight saving 60% only is provided with a blade, shearing repeatedly just can cut off limb the time, need not to apply opposite force, reduces labor intensity.
Below in conjunction with description of drawings, be described in detail the design's particular content.
Description of drawings:
Fig. 1 is the front view of single-blade formula shrub and hedge trimmer.
Fig. 2 is the cutaway view of Fig. 1.
The technical measures that realize the utility model purpose are: shearing place arranges a blade and a cramping body, arranges two outer arm torsionsprings and a connecting rod, and handle employing plastics are made and only need be applied grip and can cut off limb.
A kind of single-edge type scissors for pruning, comprise blade, handle, rivet, spring, it is characterized in that these shrub and hedge trimmer are by handle 1, handle 2, blade 3, connecting rod 4, outer arm torsionspring A, B, rivet C, D, E, F consists of, wherein handle 1 is the turnover shape, the turning point upper left quarter is the cramping body that clamping limb is used, right lower quadrant is that section is semiorbicular handle, the right part in front, turning point is provided with the perpendicular insert groove of a rivet hole and and rivet hole, and left part is provided with a rivet hole and a groove of arranging that outer arm torsionspring A uses, and the section of handle 2 is semiorbicular, it is provided with 2 rivet holes from top to bottom, the middle part of blade 3 and shank arrange respectively a rivet hole and a chute, and a rivet hole is respectively established at the two ends of connecting rod 4, and its middle part section is U-shaped; Blade 3 is connected with handle 1 by the rivet D that uses as fulcrum, outer arm torsionspring A is arranged in the groove of handle 1, the rivet C that employing is used as fulcrum is connected as a single entity handle 2, outer arm torsionspring A, handle 1, two arms of outer arm torsionspring A strut handle 1 and handle 2, rivet E is connected as a single entity outer arm torsionspring B, connecting rod 4, handle 2, two arms of outer arm torsionspring B strut handle 2 and connecting rod 4, and the other end of connecting rod 4 is connected with blade and is adopted the rivet F by the blade chute to connect. Handle 1 and handle 2 adopts plastics to make, for easy to carry and safe for the purpose of can be provided with a clasp and open a gap at blade 3 shanks at handle 2, after pruning is complete, clasp is buckled on the breach, blade is close to cramping body at this moment.
With prior art relatively, this programme has following advantage:
1. limb is positioned at edge, and the opposite side of limb is by the cramping body clamping of handle 1, and when applying grip, limb promptly is cut off; For thick and hard limb, applying grip repeatedly can very fast cut-out; Blade embeds in the limb all the time till cutting off in this course, the moment that grip is removed, and outside under the effect of brachiostrophosis spring A, B, the temporary transient cramping body that breaks away from automatically of limb.Needn't apply opposite force, depart from the problem of former joint-cutting when also not existing blade to shear once more, rapid operation, efficient improves.
2. handle 1,2 is all made of plastic, and section is semiorbicular, saves metal material, but weight reduction more than 60% is operated more laborsavingly, carries light.
3. only use a blade, be beneficial to and select the quality material manufacturing for use, improve the quality of products.
4. cost of raw and processed materials is low, helps to improve the market competitiveness.
Embodiment:
A kind of single-blade formula shrub and hedge trimmer, adopt Fig. 1, structure shown in Figure 2, blade 3 length are 120mm, Breadth Maximum is 20mm, the effective active length of blade is 50mm, rivet C, the D spacing is 32mm, handle 1,2 usefulness rigid plastics are made, and the blade line of rabbet joint is 2mm, connecting rod 4 is made by metal material, get material for H shape, once more after the punching press wherein discontinuity surface be U-shaped, blade chute right side boundary is a zigzag, outer arm torsionspring A makes handle 1,2 open, outer arm torsionspring B makes handle 2, connecting rod 4 opens, and blade 3 stretching degrees are spacing by connecting rod 4, to handle 1,2 when applying grip, connecting rod 4 promotes handle of a knife, make blade, the cramping body closure can cut limb maximum gauge be 24mm, and the limb of this diameter applies grip and can cut off for 5 times.This routine shrub and hedge trimmer total length is 190mm, and weight is 0.15kg.
