Further, the insulation handle of a knife comprises at least two first insulation handle of a knifes, and at least two first insulation handle of a knifes removably connect successively.
Further, the end of adjacent two first insulation handle of a knifes is threaded connection.
Further, the insulation handle of a knife is hollow, and the insulation handle of a knife comprises at least two first insulation handle of a knifes, and at least two first insulation handle of a knifes connect by Telescopic antenna structure.
Further, cutter head comprises the first blade and the second blade that is oppositely arranged.
Further, the respectively radially extension of edge insulation handle of a knife of the first blade and the second blade.
Further, the insulation handle of a knife is length-adjustable.
The utility model is equipped with cutter head in an end of insulation handle of a knife.During electric power tool in using the utility model, the staff makes cutter head contact with branch by control insulation handle of a knife, and when cutting off branch, by control to the insulation handle of a knife power thrusts so that branch can not touch high-tension bus-bar in the process that drops, thereby eliminated potential safety hazard.The utility model also has characteristics simple in structure, low cost of manufacture simultaneously.
Description of drawings
The accompanying drawing that consists of the application's a part is used to provide further understanding of the present utility model, and illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not consist of improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 has schematically shown the structural representation of the electric power tool in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
The utility model provides a kind of electric power tool.As shown in Figure 1, electric power tool comprises: cutter head 10 and the insulation handle of a knife 20 that removably is connected with cutter head 10.
When using electric power tool, the staff is by control insulation handle of a knife 20, cutter head 10 is contacted with branch, and when cutting off branch, by control to the power thrusts of insulation handle of a knife 20 so that branch can not touch high-tension bus-bar in the process that drops, thereby eliminated potential safety hazard, ensured the security of operation of high-tension bus-bar.Because insulation handle of a knife 20 is non-conductive, thereby the handle of a knife 20 of avoiding insulating conducts out with high-tension electricity when high-tension bus-bar is touched in misconnection, thus cause the staff face electric shock danger, cause security incident, therefore improved the security of removing branch work.Preferably, insulation handle of a knife 20 is that plastics or the materials such as rubber or timber are made.The utility model also has characteristics simple in structure, low cost of manufacture simultaneously.
Preferably, the cutter head 10 in the utility model comprises the first connecting portion 11, and insulation handle of a knife 20 comprises the second connecting portion 21 that removably connects with the first connecting portion 11.Further, the first connecting portion 11 is connected with the second connecting portion 21 by screw thread.Among the embodiment as shown in Figure 1, the first connecting portion 11 of cutter head 10 is provided with internal thread, and the second connecting portion 21 places of insulation handle of a knife 20 are provided with the external screw thread that matches with the internal thread of the first connecting portion 11.Certainly, can also the first connecting portion 11 be connected the corresponding position of connecting portion 21 and by pin the two connected.Because cutter head 10 removably is connected with insulation handle of a knife 20, thereby when cutter head 10 damages, the cutter head 10 that can more renew easily.And when cutter head 10 needs mill, also can whet a knife easily 10 work of staff, and can not increase because insulation handle of a knife 20 is long 10 the difficulty of whetting a knife.
Preferably, insulation handle of a knife 20 is length-adjustable.
Insulation handle of a knife 20 in the utility model comprises that 22, at least two first insulation of at least two first insulation handle of a knifes handle of a knife 22 removably connects (please refer to Fig. 1) successively.Because the height of branch is inconsistent and for the ease of carrying insulation handle of a knife 20, thereby the handle of a knife 20 that will insulate is arranged to the form that a plurality of the first insulation handle of a knifes 22 make up.When using electric power tool, according to the definite number that uses the first insulation handle of a knife 22 of actual conditions, then a plurality of the first insulation handle of a knifes 22 are connected successively, then remove again the work of branch.Because insulation handle of a knife 20 is the form of multistage combination, so that each first insulation handle of a knife 22 has the advantages that to be convenient to make.Preferably, the end of adjacent two first insulation handle of a knifes 22 is threaded connection.Certainly can also by pin the two be connected in the end of adjacent two first insulation handle of a knifes 22.
In a not shown embodiment, insulation handle of a knife 20 is hollow, and insulation handle of a knife 20 comprises that 22, at least two first insulation of at least two first insulation handle of a knifes handle of a knifes 22 connect by Telescopic antenna structure.At least two first successively interior nonlocal nested settings of insulation handle of a knifes 22.When using electric power tool, be installed in innermost the first insulation handle of a knife 22 by pulling, other the first insulation handle of a knifes 22 are stretched out successively, and a plurality of the first insulation handle of a knife 22 fixed by the butt power between the end of adjacent two first insulation handle of a knifes 22.
Preferably, cutter head 10 comprises the first blade 12 and the second blade 13 that is oppositely arranged.Further, as shown in Figure 1, the first blade 12 and the second blade 13 be the radially extension of edge insulation handle of a knife 20 respectively.Because all there is blade the both sides of cutter head 10, thereby make things convenient for the staff to use electric power tool according to different situations, thereby improved operating efficiency.
When using the electric power tool in the utility model, all right segmentation pollard, main method is that the cross-section at branch cuts out a fracture (this moment, branch did not also block), then by the control electric power tool be subjected to force direction at the taper place of branch firmly, thereby so that branch drop to the direction away from high-tension bus-bar.In addition, the electric power tool in the utility model can also chop at a tree or collude branch.
Because the staff no longer needs to climb tree by using electric power tool can finish the work of removing branch, thereby not only saved the personal safety that manpower has also ensured the staff.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
