Embodiment
Describe the present invention below in conjunction with accompanying drawing.
The present invention discloses a kind of extension type insulation cutter, and it comprises: adjusting portion, for regulating the working depth of insulation cutter according to actual needs; Pruning portion, is located at adjusting portion one end, for carrying out pruning action; Operating portion, is located in adjusting portion, and is connected to drive the action of pruning portion with pruning portion.
Particularly, as shown in Figure 1, the adjusting portion in the present embodiment is that the insulating sleeve 1 socket-connected by more piece is formed, and namely forms the insulating telescopic bar of hollow, is wherein positioned at outermost sleeve (i.e. outer sleeve) bottom and extends to form extension 2 downwards vertically.Pruning portion comprise be connected with inner most insulating sleeve 1 top insulated fixing rod 3, be located at first of insulated fixing rod 3 one end cut body 4 and be articulated with on insulated fixing rod 3 for cutting body 4 and coordinate to carry out second of pruning action with first and cut body 5, first cuts body 4 and second is cut between body 5 and is connected by spring 6 elasticity.When first cuts body 4 and second and cut this spring 6 when body 5 coordinates to do pruning action and be stretched.In the present embodiment, second cut the stage casing of body 5 and insulated fixing rod 3 hinged, first cuts on body 4 and is formed with the first blade 20, second first end 17 cutting body 5 is provided with the fixing hole 8 for being connected with insulation stay cord 19 (hereafter will introduce in detail), second end 18 is formed with the second blade 21 with the first blade 20 respective outer side edges, for carrying out pruning action.Concrete, in the present embodiment, the first blade 20 is arcs of recesses, and as shown in Figure 1, first cuts body 4 is approximately sickle shaped, and the second blade 21 is the convex matched with above-mentioned arcs of recesses.Operating portion comprises housing 9 and is located at the reel 11 being arranged with insulation stay cord 19 in housing 9, this reel 11 has the coiling handle 12 stretched out outside housing 9, housing 9 one end is provided with the first directive wheel 13 of guiding insulation stay cord 19, the part that housing 9 is provided with this first directive wheel 13 stretches in extension 2 by the second perforation 14 being located at extension 2, to extend in inner most insulating sleeve 1 along the axis of extension 2 after the free end of insulation stay cord 19 walks around the first directive wheel 13 and stretch out to be connected with fixing hole 8 from the upper end of inner most insulating sleeve 1, allow to cut body 5 by pulling this insulation stay cord 19 to pull second, body 4 is cut away from first to make the second end 18.When second cuts body 5 under the alternating action of the pulling force of stay cord 19 and the restoring force of spring 6 that insulate, its second end 18 can do near or cut the reciprocating motion of body 4 to prune action continuously away from first.
Further, as shown in Figure 2, in order to better fixed insulation dead lever 3, pruning portion in the present embodiment also comprises a connection piece 7, insulated fixing rod 3 is connected with inner most insulating sleeve 1 by connector 7, this connector 7 is the insulating sleeve of open at both ends, and its two ends are threaded with insulated fixing rod 3 and inner most insulating sleeve 1 respectively.In addition, perforation passing for insulation stay cord 19 can be set on this connector 7 or insulated fixing rod 3, perforation passing for insulation stay cord 19 also can be set certainly on the insulating sleeve 1 of innermost layer.Be offer perforation on the sidewall of the insulating sleeve as connector 7 in the present embodiment, stretch out to be connected with fixing hole 8 to make the insulation stay cord 19 stretched out from the upper end of inner most insulating sleeve 1 through this perforation.
During concrete operations, the fixing hole 8 that body 5 cut by insulation stay cord 19 and second is fixedly connected with, launch more piece insulating sleeve 1 according to actual needs to reaching Len req, shake coiling handle 12, insulation stay cord 19 is made to pull the first end 17 that second cuts body 5 downwards, second cuts body 5 utilizes lever principle to rotate around the bearing pin being positioned at its middle section, until the corresponding end that its second end 18 and first cuts body 4 interacts realize clipping function, namely cuts off branch etc.; Due to when pollard, be connected to first to cut the spring 6 that body 4 and second cuts on body 5 and be stretched, therefore there is stronger restoring force, now rotate backward coiling handle 12 or unclamp coiling handle 12, second cuts body 5 resets by the restoring force effect of spring 6, namely its second end 18 cuts body 4 away from first, now, again pulls insulation stay cord 19 can carry out second time and prunes action.In order to carry out spacing to insulation stay cord 19 more accurately, prevent insulation stay cord 19 from wearing and tearing simultaneously, can the second directive wheel 15 be set outside insulated fixing rod 3, regulating wheel 16 is set in extension 2.
Certainly, also a dot structure can be changed on the basis of above-described embodiment, make it have another kind of operation format, concrete, as shown in Figure 3, the bilateral symmetry relative in housing 9 lower end arranges the plate 10 that is relatively fixed, housing 9 and fixed head 10 are connected to form L-type, wherein vertical portion is housing 9, horizontal component is fixed head 10, the housing 9 be positioned between two fixed heads 10 is provided with the first perforation, and (owing to being fixed, plate 10 blocks, therefore not shown in Fig. 3), above-mentioned first directive wheel 13 is set between two fixed heads 10, the part that fixed head 10 is provided with the first directive wheel 13 stretches in extension 2 by the second perforation 14, the free end of insulation stay cord 19 is stretched in extension 2 by the first perforation and the second perforation 14 successively.Further, this the second perforation 14 is the strip gab of length direction parallel insulation sleeve 1 axis in fact, the length direction of this strip gab is simultaneously parallel with the length direction of housing 9, when for carrying out pruning work, by on carry and control insulation stay cord 19 with drop-down housing 9 and move, and then control second cuts the motion that body 5 relative first cuts body 4, to realize pruning action.
Adopt the extension type insulation cutter of the present embodiment, length can be regulated according to actual needs, to be climbed to the high point by ladder or stool without the need to user and carry out pruning work, use manpower and material resources sparingly, increase work efficiency, and mostly be insulative type material due to this extension type insulation cutter material, therefore by it, trees near alive circuit are pruned or carry out harvesting work, safety is high.
Above embodiment is only exemplary embodiment of the present invention, and be not used in restriction the present invention, protection scope of the present invention is defined by the claims.Those skilled in the art can in essence of the present invention and protection domain, and make various amendment or equivalent replacement to the present invention, this amendment or equivalent replacement also should be considered as dropping in protection scope of the present invention.
