As further improvement of the utility model, the top and bottom of above-mentioned lever are all also provided with the pulley card of a restriction steel wire rope position, make steel wire rope along lever setting; Above-mentioned lever lower end is also provided with handgrip, and handgrip is positioned at the pulley card below of lever lower end, and above-mentioned steel wire rope lower end is fixed on handgrip, when using scissors, adopts handgrip to pull steel wire rope, can be more laborsaving.
Further, between the lower handle of above-mentioned scissors and lever, be also connected with back-moving spring, make scissors be finished lower handle afterwards and get back to original position, keep scissors mouth open configuration.
Further, the above-mentioned power circuit special cutter of removing obstacles also comprises and is arranged on the containment vessel of saw on cutter, and containment vessel is coated on outside the sawtooth of saw cutter, and the two ends of containment vessel are respectively bolted on saw cutter by two.Saw cutter, when not using, is fixed on containment vessel on saw cutter, and sawtooth is wrapped in containment vessel, prevents its accidental injury maintainer; During use, turn on bolt and take off containment vessel and can use.
Preferably, above-mentioned billhook, scissors, saw cutter consist of stainless steel or high-carbon steel.
For further making the edge of a knife of billhook and scissors keep sharp, the sawtooth of saw cutter is long-term, there is larger pressure and frictional force ability to bear, as preferably, the high-carbon steel that above-mentioned billhook, scissors, saw cutter are CW6Mo5Cr4V2 by the trade mark forms.
With respect to prior art, the utlity model has following advantage and beneficial effect:
1, the utility model integrates billhook, scissors and saw cutter, without replacing instrument, very easy to use while removing different branches;
2, the utlity model has long lever, without maintainer, climb work high above the ground, reduce operating risk;
3, the utility model is simple in structure, cost is low, easy to carry.

Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but execution mode of the present utility model is not limited only to this.
[embodiment 1]
As shown in Figure 1, the power circuit of the present embodiment special cutter of removing obstacles, comprises a cylindrical long lever 1 and is arranged on billhook 2, scissors 3, the saw cutter 4 on lever 1, wherein: saw cutter 4 is vertically arranged on lever 1 top; Billhook 2 and scissors 3 are arranged on the both sides on lever 1 top, and the blade of billhook 2 is downward, the outside horizontally set of scissors 3 point of a knife, and the upper handle 31 of scissors 3 is fixed on lever 1, and lower handle 32 is connected to lever 1 lower end by steel wire rope 7.During use, for some little branches, weeds etc., can adopt billhook 2 to cut off it; The plants such as the tendril that is not easy to cut off for some, can adopt scissors 3 to cut off, and fix lever 1 during use, and then the application of force pulls steel wire rope 7 that scissors 3 closures can be cut off; For some larger branches, scissors 3 and plastic cutter 2 all cannot be cut off, and can use saw cutter 4 that it is sawed-off.The power circuit of the present embodiment special cutter of removing obstacles integrates billhook 2, scissors 3 and saw cutter 4, without replacing instrument, very easy to use while removing different branches.During manufacture, billhook 2, scissors 3, saw cutter 4 are that in an integrated whole , factory, succession is cast, and are then fixed on lever 1 top, and the connection of cutter is more firm like this.
