Description
Technical field
The present invention relates to a kind of shrub and hedge trimmer.
Background technology
Conventionally, the shrub and hedge trimmer of bimanualness are equipped with the back handle that a relative tool body casing is fixedly installed, and, in the proper site of instrument, also may be provided with a relative main body housing of energy and carry out the front hand grip of pivotable, the operating position of above-mentioned front hand grip can be according to operator's different needs, carry out the adjusting of different angles, thereby meet the requirement of comfortableness operation; Simultaneously for security consideration, in back handle and front hand grip, be equipped with switch trigger gear, only have when the switch trigger gear of back handle and the switch trigger gear of front hand grip are triggered by operator simultaneously, the switch being arranged in handle just can be triggered, and then start the machine, then by motor, instrument is carried out to driving work; In the time need to stopping the operation of machine, and only need operator to discharge any one switch trigger gear in above-mentioned forward and backward handle, switch just can disconnect, thereby has cut off the driving work of instrument.
As European patent EP 1400319B1 has disclosed a kind of shrub and hedge trimmer, these shrub and hedge trimmer are shrub and hedge trimmer of a kind of bimanualness, this tool body casing is provided with former and later two handles, the relative shrub and hedge trimmer main body of back handle is fixedly installed, shrub and hedge trimmer main body housing is pivotally connected relatively for front hand grip, therefore front hand grip relatively main body be pivoted, when operator operates shrub and hedge trimmer, all need operator's both hands to trigger the switch trigger gear that is installed on forward and backward handle simultaneously, then just can start the machine, and then the operation of pruning.The trigger action of the switch trigger gear in this shrub and hedge trimmer front hand grip transmits by lever, between lever, by inclined-plane, coordinate transmission again, due to when front hand grip is in different operating positions and operator while wanting starting switch, the reliability of the lever transmission action in the switch trigger gear of this front hand grip is not very high, and easy inefficacy causes can not starting switch.
For solving the deficiency of shrub and hedge trimmer that EP1400319B1 discloses, China bulletin patent CN200948578Y improves it, shrub and hedge trimmer have disclosed a kind of shrub and hedge trimmer, these shrub and hedge trimmer have former and later two handles, the first switch trigger gear is set on back handle, second switch flip flop equipment is set in front hand grip, a switch is set in back handle.When operator operates machines, need to trigger the first switch trigger gear and second switch flip flop equipment simultaneously, could start above-mentioned switch, the first switch trigger gear directly triggers above-mentioned switch, the interlock that second switch flip flop equipment is realized above-mentioned switch by slide block and rotating mechanism triggers, and makes these shrub and hedge trimmer safe and reliable.But the second switch flip flop equipment of these shrub and hedge trimmer can only carry out one direction operation, if while operating shrub and hedge trimmer on vertical direction, just very inconvenient, and very uncomfortable.In addition owing to must two switch trigger gears being triggered; shrub and hedge trimmer could start; as long as and have any one switch trigger gear to be wherein released; shrub and hedge trimmer will be shut down; these shrub and hedge trimmer are when vertically operating, and because operation is uncomfortable, operator is easy to depart from second switch flip flop equipment; thereby shrub and hedge trimmer are shut down, and therefore these shrub and hedge trimmer are unreliable.
Summary of the invention
