Description
The application is applicant is " plant pruning machine " in the denomination of invention of application on December 11st, 2009, the dividing an application of the Chinese invention patent application that application number is 200910260820.3.
Technical field
The present invention relates to a kind of plant pruning machine, especially relate to a kind of plant pruning machine driving by motor.
Background technology
At present, occur the multiple instrument of pruning for plant on market, for example scissors is for pruning some relatively tiny branches and leaves.Also have pruner and chain saw to be commonly used to prune relative thick trees etc.
Traditional chain saw comprises one by chain and is used for the working head that the gripper shoe of support chains forms, chain is driven by motor, around gripper shoe, rotate, traditional chain saw also comprises the main handle that is positioned at working head rear portion, the assist handle between working head and main handle.When cutting, the working head of this traditional chain saw is just subject to motor driving that chain is rotated around gripper shoe conventionally, gripper shoe is generally motionless, in cutting process, operator one holds main handle, another holds assist handle, in order to guarantee to cut, carries out smoothly, and operator's hand need to revolve and add a pressure towards cut direction.When cutting from top to bottom, because machine itself has downward gravity, this traditional chain saw is relatively easy and more laborsaving.If but need to cut from the bottom up, or need to cut from the side, operator will feel relatively to require great effort.
U.S.'s publication application has disclosed a kind of chain saw for No. US2005/0022388A1 and has comprised by chain and be used for the working head that the gripper shoe of support chains forms, chain is driven by motor, around gripper shoe, rotate, this chain saw also comprises a pair of arm being pivoted relative to each other around a fixed axis, and working head is installed on one of them arm and can be with this arm around described fixed axis another arm pivotable relatively.The handle portion that is connected with that each arm is corresponding is held for operator.In operating process, thereby described in the relative pivotable of operator, handle portion can make cutting head move and make cutting everything goes well with your work to carry out towards cut direction.But this structure makes operation is just not too comfortable in some cases, and for example, when need to cut the branch of eminence, operator's application of force is just more difficult; In addition, in the time need to cutting wood on the ground, operator just needs bending operation, if the working time is grown and is just easy to people is felt fatigue like this.
The applicant has submitted only one China patent application on April 20th, 2009, and application number is CN200910137817.2, and this Chinese patent application has disclosed a kind of chain saw, and this chain saw comprises: flexible chain; For the gripper shoe of supporting flexible chain, gripper shoe has gripper shoe plane, and gripper shoe can be around a fixed axis pivotable in this gripper shoe plane; Motor has the drive cutting element of motor output shaft for rotating; Motor shell is used for accommodating motor; Chain saw also comprises a guiding mechanism being connected with motor shell, and this guiding mechanism has a longitudinal extending axis; The exercisable longitudinal extending axis along this guiding mechanism of handle apparatus is done linear movement; Between handle apparatus and gripper shoe, by the ，Gai bindiny mechanism that is connected of bindiny mechanism, make the linear movement of handle apparatus be converted to the pivoting action of gripper shoe.Because handle apparatus is to do linear movement, so can make the operator all can be pleasant at what direction operation, be difficult for causing fatigue.But this chain saw is when handle moves linearly, its motor is normally motionless, only have gripper shoe to move by bindiny mechanism, the requirement to machining accuracy in process of the chain saw of this structure is higher, so can make processing more difficult, processing cost is higher.
