Description
Technical field
The utility model relates to a kind of vegetation pruning machine, especially relates to a kind of vegetation pruning machine by motor driven.
Background technology
At present, occur the multiple instrument that the plant class is pruned that is used on the market, for example scissors is used to prune some tiny relatively branches and leaves.Also have pruner to be commonly used to prune relative thick trees etc. with chain saw.
Traditional chain saw comprises one by chain be used for the working head that the gripper shoe of support chains forms, chain is subjected to motor driven, rotate around gripper shoe, traditional chain saw also comprises the main handle that is positioned at the working head rear portion, the assist handle between working head and main handle.When cutting, the working head of this traditional chain saw just is subjected to motor-driven to make chain rotate around gripper shoe usually, gripper shoe generally is motionless, in the cutting process, operator one holds main handle, another holds assist handle, carries out smoothly in order to guarantee cutting, and operator's hand need revolve towards cut direction and add a pressure.When cutting from top to bottom, because machine itself has downward gravity, this traditional chain saw is easier to relatively and is more laborsaving.But cutting from the bottom up perhaps needs to cut from the side if desired, and the operator will feel relatively to require great effort.
U.S.'s publication application has disclosed a kind of chain saw for US2005/0022388A1 number and has comprised by chain and be used for the working head that the gripper shoe of support chains forms, chain is subjected to motor driven, rotate around gripper shoe, this chain saw also comprises a pair of arm that is pivoted relative to each other around a fixed axis, and working head is installed on one of them arm and can pivots around relative another arm of described fixed axis with this arm.The handle portion that all is connected with of each arm correspondence is held for the operator.In the operating process, make cutting everything goes well with your work and carry out thereby the relative described handle portion of pivot of operator can make cutting head move towards cut direction.But this structure makes that in that operation is just not too comfortable in some cases, for example when needing the branch of cutting eminence, operator's application of force is just relatively more difficult; In addition, when needs cuttings was placed on the ground wooden, the operator just need stoop the waist operation, if the working time just is easy to the people is felt fatigue than length like this.
The applicant has submitted a Chinese 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; The gripper shoe that is used for the supporting flexible chain, gripper shoe have the gripper shoe plane, and gripper shoe can pivot around a fixed axis in this gripper shoe plane; Motor has the drive cutting element that motor output shaft is used to rotate; Motor shell is used to accommodate motor; Chain saw also comprises a guiding mechanism that is 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; Link to each other by bindiny mechanism between handle apparatus and the gripper shoe, this bindiny mechanism makes the linear movement of handle apparatus be converted to the pivoting action of gripper shoe.Because handle apparatus is to do linear movement,, be difficult for causing fatigue so can make that the operator can be pleasant in what direction operation.But this chain saw is when handle moves linearly, and its motor is normally motionless, have only gripper shoe to move by bindiny mechanism, the chain saw of this structure in process to the requirement of machining accuracy than higher, so can make relatively difficulty of processing, processing cost is than higher.
