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 to be solved in the present invention 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 solution adopted in the present invention is: a kind of pruner, comprise counter-rotating resetting means, tool section and tool section support, offer groove on the described tool section respectively, be respectively arranged with eccentric cam in the described groove, described tool section connects by tool section support and counter-rotating resetting means, described counter-rotating resetting means comprise output shaft, with coaxial gear wheel that connects of output shaft and torsion spring, be connected by torsion spring between described gear wheel and the output shaft.
According to another embodiment of the invention, a kind of pruner further comprises between described 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 described spacer greater than groove.
According to another embodiment of the invention, a kind of pruner further comprises the coaxial setting of described torsion spring and output shaft.
According to another embodiment of the invention, a kind of pruner comprises that further described output shaft two ends are respectively arranged with bearing.
According to another embodiment of the invention, a kind of pruner comprises that further described gear wheel cooperates with described output shaft clearance.
According to another embodiment of the invention, a kind of pruner comprises that further described output shaft and described tool section support connect.
According to another embodiment of the invention, a kind of pruner comprises that further described output shaft one end is provided with the shaft shoulder, and gear one end is extended with projection, described 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 described 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 by torsion spring; energy stored when utilizing torsion spring work releases energy automatically owing to strain when tool section blocks again; the counter-rotating of drive output shaft; 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
The present invention is further detailed explanation with preferred embodiment in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram 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 as Figure 1-3, comprise counter-rotating resetting means, tool section 1, tool section 1 ' with tool section support 5, described tool section 1, tool section 1 ' on offer respectively groove 2, groove 2 ', described groove 2, groove 2 ' in be respectively arranged with eccentric cam 7, eccentric cam 7 ', described tool section 1, tool section 1 ' connect by tool section support 5 and counter-rotating resetting means, described counter-rotating resetting means comprise output shaft 4, with output shaft 4 coaxial gear wheel that connects 3 and torsion springs 6, described output shaft 4 connects with described tool section support 5, is connected by torsion spring 6 between described gear wheel 3 and the output shaft 4.
Described tool section 1, tool section 1 ' between be provided with spacer 12, the area of described spacer 12 is greater than the area of groove, can prevent that eccentric cam from deviating from from groove.
Described gear wheel 3 adopts matched in clearance with described output shaft 4, described torsion spring 6 and output shaft 4 coaxial settings, described output shaft 4 two ends are respectively arranged with bearing 9, be convenient to slide, described output shaft 4 one ends are provided with the shaft shoulder 15, gear one end is extended with projection 16, described torsion spring 6 one ends and protruding 16 close-fittings, an end and the shaft shoulder 15 close-fittings, wherein, the described shaft shoulder 15 is back taper, and described protruding 16 are positive taper, makes that torsion spring 6 middle parts are loose than two ends, can guarantee torsion spring 6 multi-turns gathering converse rotating force like this, when tool section 1, tool section 1 ' when blocking, torsion spring 6 is a tool section 1, tool section 1 ' bigger energy is provided is convenient to tool section 1, tool section 1 ' move relative to counter-rotating.
Operation principle of the present invention is as follows: 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 by torsion spring 6, because the shaft shoulder 15 of output shaft 4 is back taper, the projection 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 by 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 determine its technical scope according to the claim scope.
