The gear linkage type dual-blade garden saw disclosed by the invention has the beneficial effects that the cutting efficiency is high and the physical power of personnel can be saved.
Description
Technical field
The present invention relates to gardens Special cutting tool technical field.
Background technology
At present, the eminence pruning cast-cutting saw that traditional gardens pruning is special, connect a saw blade by support bar to form, by arm, pressure and push-pull effort are applied to support bar during use, by the limb of eminence saw under, need not re-use ladder or other climb device climb eminence, saved pruning efficiency, avoid the potential safety hazard that high-rise working brings, improve operating efficiency.
But because saw blade is positioned at eminence, operating personnel are positioned at lower and exert a force to it, so just due to muscle power that effort lever principle consumption is too much.Concrete principle is as follows: during saw blade cutting tree limb, need three power, i.e. the thrust in blade length direction, the pulling force in blade length direction and the pressure perpendicular to cutting track.In three power, thrust and pulling force are all the power being parallel to support bar direction, and support bar is all axially stressed, this for operating personnel with on level land, cut trunk be as good as; The same vertical and support bar of pressure perpendicular to cutting track, due to support bar add operating personnel grip a little with the arm of force of saw blade cut point, so operating personnel will apply, than cutting the larger pressure of trunk on level land, so just to increase physical consumption.
Summary of the invention
Technical problem to be solved by this invention is the technical deficiency for above-mentioned existence, and provide a kind of gear linkage type biplate garden saw, its cutting efficiency is high, can save the muscle power of user of service.
The technical solution used in the present invention is: provide a kind of gear linkage type biplate garden saw, comprises fixed frame, arc saw blade that two symmetrical and concave arcs are arranged in opposite directions; Same one end of two arc saw blades is respectively rotationally connected by a rotating shaft and fixed frame; Each rotating shaft is respectively provided with a gear; Each gear and its link at the arc saw blade of same rotating shaft; Two gears meshing; The bottom of fixed frame is provided with support bar; The bottom of two arc saw blades connects by extension spring; Opening between the upper end of two arc saw blades is in the shape of falling the Eight characters.
Further optimization the technical program, each arc saw blade of gear linkage type biplate garden saw all with the rotating shaft pin joint at its place; Fixed frame comprises two fixed heads be arranged in parallel; Two fixed heads are fixed by the bolt of surrounding; The two ends of each rotating shaft are placed in the axis hole of two fixed heads respectively; The upper end of support bar is fixed with U-shaped geometrical clamp; Two sides of U-shaped geometrical clamp respectively with two fixed heads by bolt tightening.
The invention has the beneficial effects as follows:
1, simple to operate, time saving and energy saving.The present invention in use, the upper end of direct two arc saw blades pushes the tree limb that will cut to, then reciprocating sliding support bar, extension spring is pressure required when saw blade provides cutting, and two meshed gears ensure that two arc saw blades must link under keeping symmetry status; Below operating personnel's reciprocating sliding support bar, need not apply pressure along the radial direction of support bar again.In addition, because the present invention adopts two arc saw blades to cut simultaneously, improve cutting efficiency.
2, stabilized structure, maintainability are by force.Two bolt of fixing plates connect and compose can the fixed frame of dismounting, and arc saw blade and rotating shaft pin joint, be convenient for changing after damage.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Shown in Fig. 1-Fig. 3, gear linkage type biplate garden saw, comprises the arc saw blade 3 that the symmetrical and concave arc 2 of fixed frame 1, two is arranged in opposite directions; Same one end of two arc saw blades 3 is respectively rotationally connected by a rotating shaft 4 and fixed frame 1; Each rotating shaft 4 is respectively provided with a gear 5; Each gear 5 links at the arc saw blade 3 of same rotating shaft 4 with it; Two gears 5 engage; The bottom of fixed frame 1 is provided with support bar 6; The bottom of two arc saw blades 3 connects by extension spring 7; Opening 8 between the upper end of two arc saw blades 3 is in the shape of falling the Eight characters; Each arc saw blade 3 all with rotating shaft 4 pin joint at its place; Fixed frame 1 comprises two fixed heads be arranged in parallel 9; Two fixed heads 9 are fixed by the bolt of surrounding; The two ends of each rotating shaft 4 are placed in the axis hole 10 of two fixed heads 9 respectively; The upper end of support bar 6 is fixed with U-shaped geometrical clamp 11; Two sides of U-shaped geometrical clamp 11 respectively with two fixed heads 9 by bolt tightening.
When cutting tree limb, two arc saw blades 3 open, the concave arc 2 of two arc saw blades 3 is arranged in opposite directions, is conducive to angle between the cut point line of reduction two arc saw blades 3 and the cutting track line of arc saw blade 3 like this, thus the thrust provided required for reduction support bar 6 or pulling force.In addition, the concave arc 2 of two arc saw blades 3 can also prevent tree limb in the process of cutting from opening 8 slippage.Opening 8 is herringbone shape, like this when pushing two arc saw blades 3 to tree limb, can slide between two arc saw blades 3 from opening 8 tree limb during tree limb, simple to operate.
The effect of extension spring 7 makes two arc saw blades 3 remain in the pulling force of closed trend, in the process of cutting tree limb, can save the muscle power that operating personnel consume on operation support bar 6.
Two meshed gears 5 effects make the action reversed of two arc saw blades 3 synchronous, because gear 5 and arc saw blade 3 are linked by rotating shaft 4, so when engagement two gears 5, keep the line of symmetry of two arc saw blades 3 parallel with support bar 6, such support bar 6 is just in two arc saw blades 3 and presss from both sides on bisector of angle.
