Abstract

The utility model relates to a pair of multi-purpose forest fruit shears which is improved and designed on the basis of the existing lopping shears. The utility model comprises a grab handle, an operational handle, an operational handle shaft, a spring, a rod pipe, an upper sleeve, a lower sleeve, a pair of mutually engaged ratchet wheels, ratchet wheel shafts, a ratchet wheel impaction device, a groove pulley, a spherical radial bearing, a groove pulley shaft, a thin steel rope, a left shearing arm, a right shearing arm and a shearing shaft, wherein the steel rope connected to the right shearing arm is turned by the groove pulley, passes through an inner cavity of the rod pipe and is fixed to a rope hole at the lower end of the operational handle. The action of shearing at hand part can be spread to the right shearing arm of the upper part through the thin steel rope, the shears are used for pruning operation, and the engaged ratchet wheels can be used for rotating the shears at any angle.

Description

Use fruit tree shears more

The utility model is used fruit tree shears more, is a kind of instrument that is used for the agriculture and forestry beta pruning, plucks fruit, belongs to agriculture and forestry machinery.

Shrub and hedge trimmer in the past are hand-held, and the weak ixeris herb and the spring that are combined by lever and lever constitute; Only be useful on and shear the branch that arm gets at, perhaps use the ladder beta pruning, very inconvenient, and also dangerous, also damage forest.At present still do not have suitable shrub and hedge trimmer can cut branch and fruit, the flower etc. of eminence, and agriculture and forestry are badly in need of this suitable instrument very much in terrestrial operation.

Task of the present utility model will design a kind of how cutting with the high pin of industry of planting forest or fruit tress exactly, be used to cut the branch of eminence and fruit etc., and require scissors can turn to needed angle aloft, flexible as the hand-held shrub and hedge trimmer, it is simple, quick, safe and reliable to cut branch, can increase work efficiency.

The utility model is to improve design according to above-mentioned invention task on the basis of existing hand-held shrub and hedge trimmer, shown in Figure of description the utility model by lever 1, lever 23, operation arbor 2, rod tube 4, setting of casing 3, last sleeve pipe 5, intermeshing a pair of ratchet 12,11 and ratchet shaft 10, compress the spring 8 and the nut 9 of ratchet, groove pulley 6 and groove pulley spindle 19, seizing wire 17,20, left side right shearing arm 13,15 and cut axle 14; Lever 1 is fixedly connected on the setting of casing 3, setting of casing 3 is connected with rod tube 4 with screw thread respectively with last sleeve pipe 5, and with holding screw 21,18 are locked on the rod tube 4, fixedly connected with quiet ratchet 11 in left side, last sleeve pipe 5 upper ends, fixedly connected with groove pulley spindle 19 in the right side, groove pulley 6 is contained on the groove pulley 19, can rotate around axle 19, seizing wire 17,20 upper ends are fixed on right shearing arm 15 lower ends, pass through in the middle of rod tube 4 by groove pulley 6, be fixed to the rope hole 22 of lever 23, moving ratchet 12 is fixedlyed connected with left shearing arm 13, and is fixed on the ratchet shaft 10 with holding screw 7, and ratchet shaft 10 can slide in quiet ratchet centre bore 11 or rotate, the engagement of two ratchet nationality teeth, nationality spring 8 and nut 9 compress.When scissors and the rotation of moving ratchet,, quiet ratchet can not can only force ratchet shaft 10 to be gone here and there to the right and move along with rotation because of being fixed on the sleeve pipe 5, compression spring 8, when scissors forwards required angle to, power stops operating, scissors just is fixed on this position by quiet ratchet, carries out cut operator; During the beta pruning action, hold lever 1 and lever 23, when pressing lever 23, the seizing wire 17,20 that is fixed on the rope hole 22 is pulled downwards, affect right shearing arm 15 by groove pulley 6, and compression spring 16 makes left right shearing arm produce shear action, when hand is decontroled, spring 16 resets, and scissors opens again.

Preferred forms: for scissors energy balanced rotation certain angle, the horizontal segment of requirement seizing wire 17 and ratchet shaft 10 center lines are on same straight line, should adopt self-centering type (standard component) sphere radial bearing to guarantee that become different angles time slot pulley 6 to rotate with pipe smooth when scissors between groove pulley spindle 19 and the groove pulley 6, for alleviating the deadweight that high pin is cut, each parts is guaranteeing to adopt light material under mechanical strength and the life-span prerequisite as far as possible, as aluminium alloy, engineering plastics etc., because of the material difference, connected mode also can change; The nut 9 on quiet ratchet 11 left sides for the ease of with whole spring 8 degrees of tightness of hand adjustment, can adopt wing nut; Rod tube 4 can adopt multi-section type, comes spreading rod tube 4 according to the height of setting; During on-the-spot the use,, can before act is got on, rotate by hand,, scissors can be propped up hard branch, force scissors to rotate, forward certain angle to, to adapt to the operation needs if in use will change the scissors angle underground as changing the angle of scissors; Seizing wire also can replace with nylon rope.

Effect of the present utility model:

(1) rod tube spreading is arbitrarily held the branch that following lever and action bars can be cut eminence.

(2) angle of sound ratchet engages adjustable scissors is arranged, the branch that can wipe out is all wiped out from crotch, can not adjusting angle because of scissors, and it is oversize to stay oblique stubble, gives birth to water sprout from here again, only consumes nutriment and does not yield positive results.

(3) the utility model can be used for vast rural area, gardens, fruit tree, flower industry, is used for beta pruning, retraction tree crown, applied range.

(4) this product design is reasonable, and is easily manufactured, the small investment of founding the factory, and instant effect, cost is low, high efficiency.Small towns and individual enterprise that the most suitable fund is few practice midwifery.
