The invention relates to the technical field of special cutting tools for gardens and discloses a connecting rod-linked two-piece garden saw. The saw comprises a fixed frame and two bilaterally-symmetrical arc-shaped saw blades with oppositely arranged concave arcs. The same ends of the two arc-shaped saw blades are rotatably connected with the fixed frame in virtue of rotating shafts respectively; the lower end of the fixed frame is provided with a supporting rod; one ends of four pullback springs are fixed at the lower parts of the two arc-shaped saw blades in an intersected manner; the other ends of the four pullback springs are connected through a scissor-type connecting rod; the lower ends of the two arc-shaped saw blades are respectively connected with pull rods through the rotating shafts; the free ends of the two pull rods are both connected with a vertically arranged guide rod via the rotating shafts; the central part of the upper end of the fixed frame is provided with a guiding slideway which is in sliding fit with the lower part of the guide rod; the lower part of the guide rod is located in the guiding slideway; and the opening between the upper parts of the two arc-shaped saw blades is splayed. The connecting rod-linked two-piece garden saw provided by the invention has the beneficial effects of high cutting efficiency and capacity of saving physical power of users.
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 connection-rod linkage formula 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 connection-rod linkage formula 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; The bottom of two arc saw blades is provided with support bar; The bottom intersection of two arc saw blades is fixed with four extension springs; Four extension spring other ends connect by scissor-type connecting rod; The bottom of two arc saw blades also each axis of rotation is connected with a pull bar; The free end of two pull bars is all connected with a guide post rotating shaft vertically arranged; Fixed frame upper center has the guide slide coordinated with guide post lower slide; In guide post lower portion guide slide; Opening between the upper end of two arc saw blades is in the shape of falling the Eight characters.
Further optimization the technical program, the support bar of connection-rod linkage formula biplate garden saw is socketed by least two in the longitudinal direction and the sleeve pipe be slidably matched is formed; Adjacent two sleeve pipes are tightened by Bolt to position.
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, four extension springs arranged in a crossed manner are pressure required when saw blade provides cutting, two pull bar reverse sync motions under the restriction of guide post, conductor rod moves up and down in wire slideway; 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, support bar changes length by the socket length between adjustment sleeve pipe, can adapt to the cutting operation of differing heights.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Shown in Fig. 1, Fig. 2, connection-rod linkage formula 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; The bottom of fixed frame 1 is provided with support bar 5; The bottom intersection of two arc saw blades 3 is fixed with four extension springs 6; Four extension spring 6 other ends connect by scissor-type connecting rod 7; The bottom of two arc saw blades 3 also each axis of rotation is connected with a pull bar 8; The free end of two pull bars 8 is all connected with guide post 9 rotating shaft vertically arranged; Fixed frame 1 upper center has the guide slide 10 coordinated with guide post 9 lower slide; In guide post 9 lower portion guide slide 10; Opening 11 between the upper end of two arc saw blades 3 is in the shape of falling the Eight characters; Support bar 5 is socketed by least two in the longitudinal direction and the sleeve pipe 12 be slidably matched is formed; Adjacent two sleeve pipes 12 are tightened by Bolt to position.
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 5 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 11 slippage.Opening 11 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 11 tree limb during tree limb, simple to operate.
Four extension springs 6 are arranged in a crossed manner, connected together by scissor-type connecting rod 7, jointly for two arc saw blades 3 provide the pulling force remaining in closed trend, in the process of cutting tree limb, can save the muscle power that operating personnel consume on operation support bar 5.
The effect of two pull bars 8 makes the action reversed of two arc saw blades 3 synchronous, and its principle is that the guide post 9 by sliding up and down in guide slide 10 keeps the pin joint of two pull bars 8 to be positioned at two pull bars 8 all the time pressing from both sides on bisector of angle.Such support bar 5 is just in two arc saw blades 3 and presss from both sides on bisector of angle, and the thrust apply support bar 5 or pulling force press from both sides on bisector of angle at two pull bars 8 does not have component.
