Abstract
The invention relates to a pruning machine which comprises a reversal resetting device, a blade and a blade bracket, wherein grooves are respectively arranged on the blade; eccentric cams are respectively arranged in the grooves; the blade is adapted with the reversal resetting device by the blade bracket; the reversal resetting device comprises an output shaft, a bull wheel which is coaxially adapted with the output shaft, and a torsion spring; and the bull wheel is connected with the output shaft by the torsion spring. The invention automatically releases energy due to elastic deformation when the blade is clamped by utilizing energy stored when the torsion spring works by the skillful matching of the torsion spring with the bull wheel and the output shaft and drives the output shaft to reverse so as to drive the blade to automatically reset and reverse, protects cutter teeth on the blade without clamping hard objects, such as steel wires, and the like, is difficult to damage the blade and improves the safety of a consumer in use.
Description
Technical field
The present invention relates to a kind of electric tool, especially a kind of pruner.
Background technology
Pruner belongs to the special-purpose cutting implement of gardening, can prune and repairs for shrub, hedge, along with the continuous development of afforestation undertaking; Pruner becomes a kind of indispensable greening instrument; It has efficient height, advantage such as easy to use, shows also that in actual use safety shut-down control is very important, has only two kinds and brake modes is current; One of which is a mechanical brake, the mechanical brake complex structure; It two is an electric brake.
Existing pruner is because of the multiple rotating function that do not reset; So when tool section is blocked by steel wire or other hard thing, be difficult to tool section is separated with steel wire or other hard thing, and; When by force tool section being separated with steel wire or other hard thing; Make tool section be easily damaged, bring quite inconvenience, also easily the user is caused danger to the user.
Summary of the invention
In order to overcome above defective, the technical problem that the present invention will solve is: propose a kind of simple and reasonablely, can reset when tool section is stuck, do not allow the counter-rotating resetting means of flimsy pruner.
The technical scheme that the present invention adopted is: a kind of pruner; Comprise counter-rotating resetting means, tool section and tool section support; Offer groove on the said tool section respectively, be respectively arranged with eccentric cam in the said groove, said tool section connects through tool section support and counter-rotating resetting means; Said counter-rotating resetting means comprise output shaft, with coaxial gear wheel that connects of output shaft and torsion spring, be connected through torsion spring between said gear wheel and the output shaft.
According to another embodiment of the invention, a kind of pruner further comprises between said two tool sections and is provided with spacer.
According to another embodiment of the invention, a kind of pruner further comprises the area of the area of said spacer greater than groove.
According to another embodiment of the invention, a kind of pruner further comprises the coaxial setting of said torsion spring and output shaft.
According to another embodiment of the invention, a kind of pruner comprises that further said output shaft two ends are respectively arranged with bearing.
According to another embodiment of the invention, a kind of pruner comprises that further said gear wheel cooperates with said output shaft clearance.
According to another embodiment of the invention, a kind of pruner comprises that further said output shaft and said tool section support connect.
According to another embodiment of the invention, a kind of pruner comprises that further said output shaft one end is provided with the shaft shoulder, and gear one end is extended with convexity, said torsion spring one end and protruding close-fitting, an end and shaft shoulder close-fitting.
According to another embodiment of the invention, a kind of pruner further comprises the said shaft shoulder, protruding tapered.
The invention solves the defective that exists in the background technology; Cooperate with the ingenious of gear wheel and output shaft through torsion spring, energy stored when utilizing torsion spring work releases energy owing to strain when tool section blocks automatically again, drives the output shaft counter-rotating; The counter-rotating thereby driving knife bar automatically resets; Protected the cutter tooth on the tool section can not block hard things such as steel wire again, tool section is not easy to damage, and has improved consumer's safety in use.

Embodiment
Combine accompanying drawing and preferred embodiment that the present invention is done further detailed explanation now.These accompanying drawings are the sketch map of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
A kind of pruner shown in Fig. 1-3; Comprise counter-rotating resetting means, tool section 1, tool section 1 ' with tool section support 5; Said tool section 1, tool section 1 ' on offer respectively groove 2, groove 2 '; Said groove 2, groove 2 ' in be respectively arranged with eccentric cam 7, eccentric cam 7 ', said tool section 1, tool section 1 ' connect, said counter-rotating resetting means through tool section support 5 and counter-rotating resetting means comprise output shaft 4, with output shaft 4 coaxial gear wheel that connects 3 and torsion springs 6; Said output shaft 4 connects with said tool section support 5, is connected through torsion spring 6 between said gear wheel 3 and the output shaft 4.
Said tool section 1, tool section 1 ' between be provided with spacer 12, the area of said spacer 12 is greater than the area of groove, can prevent that eccentric cam from deviating from from groove.
Said gear wheel 3 adopts matched in clearance with said output shaft 4, and said torsion spring 6 is respectively arranged with bearing 9 with output shaft 4 coaxial settings, said output shaft 4 two ends, is convenient to slide; Said output shaft 4 one ends are provided with the shaft shoulder 15, and gear one end is extended with convexity 16, said torsion spring 6 one ends and protruding 16 close-fittings; One end and the shaft shoulder 15 close-fittings, wherein, the said shaft shoulder 15 is back taper; Said protruding 16 are positive taper, make that torsion spring 6 middle parts are loose than two ends, can guarantee torsion spring more than 6 circle gathering converse rotating forces like this; When tool section 1, tool section 1 ' when blocking, torsion spring 6 is tool section 1, tool section 1 ' bigger energy is provided, be convenient to tool section 1, tool section 1 ' reverse relatively and move.
Operation principle of the present invention is following: the motor 13 that is connected with gear wheel 3 drives gear wheel 3 rotations; Gear wheel 3 drives output shaft 4; Thereby drive eccentric cam 7, eccentric cam 7 ' rotation; The translation of eccentric cam 7, eccentric cam 7 ' drive respectively blade 1, blade 1 ' do relative direction is sheared to produce, and reaches the pruning purpose.Cooperate with gear wheel 3 and the ingenious of output shaft 4 through torsion spring 6, because the shaft shoulder 15 of output shaft 4 is back taper, the convexity 16 of gear wheel 5 is positive taper; Make that torsion spring 6 middle parts are loose than two ends, stored energy when utilizing torsion spring 6 work is when blade 1, blade 1 ' when being blocked by hard things such as steel wires; Torsion spring 6 releases energy automatically; Drive output shaft 4 counter-rotatings, thereby make blade 1, the blade 1 ' counter-rotating that resets, reach the purpose that automatically resets and break away from.With above-mentioned foundation desirable embodiment of the present invention is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
