Description

A kind of pruner

Technical field

The utility model relates to a kind of pruner.

Background technology

Pruner is the instrument that is used for cutting commonly used in the industry of gardens, to branch, hedge or shrub are pruned arrangement, particularly along with the continuous development of motherland's afforestation undertaking, people improve constantly the requirement of living and working environment, pruner is because easy to use, fast, the efficient advantages of higher, obtained the large-scale popularization use, there are scientific and technical personnel that traditional pruner is constantly made new improvement for this reason, as the patent No. is that 03231441.8 Chinese patent is a class of representative, security control mechanism to pruner improves, when having only shift knob on the major-minor handgrip all to press, pruner could be worked, improved safety, avoided the generation of pruner casualty accident, also having the patent No. is the Chinese patent " pruner " of 200420107583.X, it has carried out improving design to the handgrip of pruner, handgrip can be rotated, adapt to the use on the various occasions, thereby reduce labor intensity.But, the common fault that pruner just exists is, set of blades changes from main frame not too easily, and in the actual use, set of blades is than the parts that are easier to wear and tear or destroyed by extraneous foreign matter, and is pretty troublesome if set of blades can not change or change, in case will cause set of blades to be worn or destroy, the user can not go to repair it, and whole pruner has just been scrapped, and causes wasting of resources phenomenon, secondly, traditional pruner adopts one type pruning set of blades, causes the scope of application narrow, can only prune, can not be used for sawing, can not be used for cutting big branch, so, limited promoting the use of of it; In addition, the handle of pruner is shorter, so can not be used for pruning on the wall or the branch on the high tree, the help that need use ladder makes many users feel very inconvenient, at last, traditional pruner can not be close to the ground and prune, and needs people's operation of bending over, and is very painstaking, so, need us to do further improvement.

Summary of the invention

Technical problem to be solved in the utility model provide a kind of rational in infrastructure, prolong handle, widen the pruner scope of application, use pruner easy to carry.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of pruner, it includes casing, electromotor is installed in the casing, drive the set of blades up and down that is connected with the output shaft of electromotor, control electromotor work whether shift knob and power unit, it is characterized in that described casing molds a jack for the connecting rod insertion in the rear end, Electric plug with shutter is housed in the jack, accordingly, connecting rod is provided with electric-connected socket in insertion end, plug is electrically connected with socket, and, on the connecting rod upper handle, button is housed, be the trigger switch that cooperates below the button, trigger switch is by electric wire and plug, socket and electromotor form the control electric power loop.
