Description of the drawings
Fig. 1 is immovable support described in the utility model and movable carriage schematic view of the mounting position.
Fig. 2 is insulating bar structural schematic diagram described in the utility model.
Fig. 3 is driving mechanism structure schematic diagram described in the utility model.
Specific implementation mode
The following describes the utility model in further detail with reference to the accompanying drawings, to enable those skilled in the art with reference to explanation
Book word can be implemented according to this.
As shown in Figure 1, the utility model provides a kind of flexible averruncator of insulated type, including immovable support 110, it is described solid
The top of tool fixing frame 110 is provided with fixed blade 111.The middle part of movable carriage 120 is hinged on immovable support 110, to make
Movable carriage 120 can be rotated around hinge joint relative to immovable support 110.The movable carriage 120 is fixedly arranged at the front end with activity
Blade 121, the fixed blade 111 and movable blades 121 constitute two blades of scissors, by making 120 turns of movable carriage
It is dynamic, make movable blades 121 close to fixed blade 111, makes to form shearing force between them, branch is cut.
One end of spring 130 is connected to the top of immovable support 110, and the other end is connected to the rear end of movable carriage 120, leads to
The pulling force effect for crossing spring 130 keeps fixed blade 111 and movable blades 121 mutually separate, makes to open up into maximum angle between them
Degree.
The bottom of the immovable support 110 is provided with mounting hole, together referring to Fig.2, the top of insulating bar 140 is provided with company
Connector 141, the connector 141 are inserted into mounting hole, to make immovable support 110 be fixed on the top of insulating bar 140
End.The connector 141 is connect with mounting hole by bolt-type and ball connection type, or is attached using screw thread.
The bottom of the insulating bar 140 is provided with connecting hole, and two insulating bars 140 can link together, will wherein one
The connector 141 and the connecting hole of another insulating bar 140 of a insulating bar 140 are attached.Can according to actual height demand,
Multiple insulating bars 140 are connected, realize the flexible effect lengthened.Bolt-type and ball are equally used between two insulating bars 140
Connection type connects, or is attached using screw thread.
The utility model further include with driving mechanism, for drive movable carriage 120 relative to immovable support 110 rotate,
Keep fixed blade 111 and movable blades 121 mutually close, is sheared.
The driving mechanism includes the first pulley 112 being arranged in 110 lower part of immovable support, is arranged in movable carriage 120
The second pulley 122 of rear end, also cotton rope 150.One end of the cotton rope 150 is fixed on the rear end of movable carriage 120, then line
Rope 150 bypasses first pulley 112 and second pulley 122 successively, then hangs to lower section.Make energy when pulling downward on cotton rope 150
The elastic force for enough overcoming spring 130 makes movable carriage 120 be rotated relative to immovable support 110, is sheared.
As shown in figure 3, the driving mechanism further includes that the lower part of the lowermost insulating bar 140 is being provided with spool
151, the spool 151 is rotatable to be connect with insulating bar 140.It is coaxially fixed with worm gear 152 with the spool 151.Worm screw 153
Both ends be rotatably supported at positioned at the lower part of the lowermost insulating bar 140, the worm screw 153 nibbles with 152 phase of the worm gear
It closes.One end of the worm screw 153 is provided with handwheel, drives worm screw 153 to rotate by rotating handwheel, and then drive 152 He of worm gear
The logical rotation of spool 151 1, cotton rope 150 is wrapped on spool 151, equally plays the role of pulling downward on cotton rope 150.Due to snail
Characteristic of the worm and gear transmission with self-locking, what need not be continued as direct pull cotton rope pulls down, and need to only rotate certain
The handwheel of angle, stopping can be rotated further, and cotton rope will not return, this brings great convenience for operator.
The top of the immovable support 110 is additionally provided with saw blade 113, and the branch cut can will be not easy by saw blade 113
Under saw.Fixed blade 111 and movable blades 121 are all made of SK5 carbon, C steel materials and are made.
The utility model, to needing working at height pruning trees to carry out implementation application, uses under transmission line of electricity power channel
The convenient and efficient completion tree trimming of the tool improves and manually coordinated the working efficiency trimmed with Operation Van in the past, subtracts
Labor intensity is lacked, has reinforced using proficiency to averruncator during routine use, promote the work of power channel trimming
Industry quality, while also adding at a distance from danger area, increases safety, and labor intensity is big, efficiency is low to solving, and
Has the problem of certain risk.
It is not only in the description and the implementation although the embodiments of the present invention have been disclosed as above
Listed utilization.It can be applied to various fields suitable for the present invention completely.For those skilled in the art,
