Description
Technical field
The present invention relates to a kind of shrub and hedge trimmer.
Background technology
Usually, the shrub and hedge trimmer of bimanualness are equipped with the back handle that a relative tool body casing fixedly installs, and, proper site at instrument also may be provided with the front hand grip that a relative main body housing of energy pivots, 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 satisfy the requirement of comfortableness operation; Simultaneously for security consideration, be equipped with switch trigger gear on back handle and the front hand grip, when having only switch trigger gear when the switch trigger gear of back handle and front hand grip not to be operated the person simultaneously to trigger, the switch that is arranged in the handle just can be triggered, and then start the machine, by motor instrument is carried out driving work then; When needs stop the operation of machine, and only need the operator to discharge any one switch trigger gear in the above-mentioned forward and backward handle, switch just can disconnect, thereby has cut off the driving work of instrument.
A kind of shrub and hedge trimmer have been disclosed as European patent EP 1400319B1, 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 fixedly installs, then the 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 the 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, just can start the machine then, 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, cooperate transmission by the inclined-plane again between the lever, when the operator wants starting switch owing to being in different operating positions when front hand grip, 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, first switch trigger gear is set on the back handle, the second switch flip flop equipment is set on the front hand grip, a switch is set in the back handle.When the operator operates machines, need trigger first switch trigger gear and second switch flip flop equipment simultaneously, could start above-mentioned switch, first switch trigger gear directly triggers above-mentioned switch, the second switch flip flop equipment realizes that by slide block and rotating mechanism the interlock of above-mentioned switch triggers, and makes that these shrub and hedge trimmer are safe and reliable.But the second switch flip flop equipment of these shrub and hedge trimmer can only carry out folk prescription to operation, if operation during shrub and hedge trimmer on the vertical direction is just very inconvenient, and very uncomfortable.In addition because when must two switch trigger gears being triggered; shrub and hedge trimmer could start; as long as and have any one switch trigger gear wherein to be released; shrub and hedge trimmer will be shut down; these shrub and hedge trimmer are when vertically operating, because operation is uncomfortable, the operator is easy to break away from the second switch flip flop equipment; thereby shrub and hedge trimmer are shut down, so these shrub and hedge trimmer are unreliable.
