Embodiment
Referring to Fig. 1, be the combining structure schematic diagram of multi-functional high-altitude of the present utility model shrub and hedge trimmer, as main part cut handle 1, perching knife 2-1, billhook 2-2, active cutter plate 3, saw 4 is arranged in order and is installed on the central pin shaft 8.Wherein, perching knife 2-1, billhook 2-2 are that the one formation is decided snip 2, and deciding snip 2 is the boundary with middle pin hole, and the perching knife 2-1 of crescent shape is arranged to have in the upper-outer circumference top, can directly root out side shoot; Inner rim is the billhook 2-2 of circular arc concavity, and the disconnected side shoot of energy hook also is a working face of scissors simultaneously.Another working face of scissors is an active cutter plate 3, and its blade is a convex arc shaped, with decide snip 2 on the working face of circular arc concavity cooperate and constitute scissors.Ratchet 3-1 and active cutter plate 3 also connect one, are packed on the central pin shaft 8, and the rotation of ratchet 3-1 is stirred by cutting the ratchet 1-6 (see figure 5) that is provided with on the handle 1, by the effect of cutting handle 1, can realize the beta pruning operation.This scissors utilizes lever principle, when the blade mid point is constant to AL, can be lengthened to about 2.5m cutting handle, makes the power arm and the ratio of resistance arm reach 25～35 times, can increase shearing force greatly thus.Be provided with circular sleeve 2-4 at the lower end of deciding snip 2, be used to connect the mobile jib 5 that supports whole shrub and hedge trimmer, be equipped with in the side of sleeve 2-4 and be used to cut that handle 1 opens or the main spring 6 of return, the last elater 6-1 of main spring 6 stretches into and cuts in the handle 1, and following elater 6-2 is fixed on the mobile jib 5.Be provided with stay cord 7 near the place, outer end of cutting handle 1, be used to cut the flexible folding of handle 1.
In conjunction with Fig. 1, referring to Fig. 2, Fig. 3, Fig. 4, Fig. 5, be the structural representation of cutting handle 1, this is cut handle 1 and is the suit body, and built-in movable governor motion can be realized telescopic adjustment aloft.Cutting handle 1 is made up of outer toggle 1-1, interior toggle 1-2, moving tooth handle 1-3, auxilliary handle 1-4, movable governor motion, wherein, the end of moving tooth handle 1-3 is connected with interior toggle 1-2, for increasing the intensity of moving tooth handle 1-3, be provided with auxilliary handle 1-4 with the parallel place of moving tooth handle 1-3, and together be sleeved on the central pin shaft 8 with moving tooth handle 1-3, on moving tooth handle 1-3, be provided with the ratchet 1-6, the spring 1-7 that are used to stir ratchet, the solid tire 10, the spring 9 that are used for brake ratchet and retreat are installed on central pin shaft 8, Gu tire 10 under the effect of spring 9 with tightly interlock of ratchet 3-1.When cutting handle 1 when central pin shaft 8 rotates, ratchet 1-6 stirs ratchet 3-1 and rotates, and makes the active cutter plate 3 beta pruning acting of upwards overturning.When cutting handle 1 and upwards rotate, Gu that tire 10 blocks ratchet 3-1 is motionless, active cutter plate 3 can only rotate acting forward like this, can not reverse.The cross section of cutting inside and outside toggle 1-1, the 1-2 of handle 1 is a U-shaped, and Open Side Down for U (referring to Fig. 4), and wherein outer toggle 1-1 has inflexed hook, can be connected with interior toggle 1-2 suit also slidably.Be disposed with a plurality of location adjustment hole 1-5 on the outer toggle 1-1, interior toggle 1-2 is provided with the movable governor motion that can directly regulate aloft, is used to control cut elongating or shortening of handle.Movable governor motion is made up of button 11, spring 12, fulcrum 13, plug 14, lever 15, each member is installed on the interior toggle 1-2 successively, plug 14 is provided with 45 ° inclined-plane, and the bottom connects lever 15, and the other end of lever 15 connects the button 11 that spring 12 is housed.It manipulates method: cut handle 1 when standing state, it is sagging naturally parallel with mobile jib 5 under the traction of stay cord 7 to cut handle 1, when handle 1 is cut in the needs elongation, rope another skew back to mobile jib 5 is drawn, force button 11 to rely on mobile jib 5, utilize inwardly compression button 11 of mobile jib 5, under the effect of spring 12, lever 15 moves downward by fulcrum 13, drives toggle 1-2 in plug 14 retractions, outer toggle 1-1 is sagging naturally elongation under action of gravity, at this moment suitable slack rope is put down button 11 gently, when plug 14 runs into location adjustment hole 1-5 on the outer toggle 1-1, will spring into automatically, fix with this outer toggle 1-1.When handle 1 is cut in the needs shortening, unclamp rope, button 11 and plug 14 restPose, and the handle 1 of cutting that is fixed opens under the elastic force of main spring 6, moves stay cord 7 and the straight line that grows up to of cutting handle 1 when opening a business to 160 °～17 °.The pulling rope makes outer toggle 1-1 top hit the inclined-plane of plug 14, and when toggle 1-2 in plug 14 retractions, outer toggle 1-1 continued to slide into location adjustment hole 1-5, plug 14 ejected hand-hole, and outer toggle 1-1 is fixed.If wanting to continue to shorten cuts handle 1, continue stay cord 7, long to reaching desired shank.In this case, the effective length operated by rotary motion of cutting handle 1 is about 2.5m.
In conjunction with Fig. 1, referring to Fig. 6, the saw handle 4-1 position of described saw 4 is provided with locating button bolt 4-3 and the elastic steel sheet 4-2 that is used to lock saw blade, locating button bolt 4-3 and sawtooth one side in the same way is provided with the inclined-plane of 45, locating button bolt 4-3 is under the pressure of elastic steel sheet 4-2, see through the saw hole through another side, with decide snip 2 on the button door 2-3 of setting match, can lock saw blade.It manipulates method: saw 4 is sought a branch aloft and is done the strong point, reverse mobile jib 5, pass through the strong point, make saw 4 rotations,, utilize the inclined-plane of 45 on the locating button bolt 4-3 when saw 4 turns to when deciding snip 2 and contact around central pin shaft 8, saw 4 is attached to decides on the snip 2 when forwarding button door 2-3 position to, locating button bolt 4-3 springs in the button door 2-3, will saw locking, and can cooperate this moment with stay cord 7 saws an operation.After the operation of saw branch was finished, decide snip 2 down, saw 4 was in last position, and load suitably firmly presses down on trunk, and locating button bolt 4-3 is extracted out in button door 2-3, will saw 4 then and rotate the sagging standing state that returns to by former road.
Referring to Fig. 7, be of the present utility model couple of bar mode of operation figure, when the beta pruning operation when 9m is following, single swinging boom when operation height 9～15m, for stablize mobile jib 5, installs an auxiliary side lever 5a additional on mobile jib 5 tops, becomes two bars and operates; When operation highly surpasses 15m, can install a side lever again additional, become the operation of three bars.
