Embodiment
Please refer to Fig. 1 to 3, the shrub and hedge trimmer 100 of present embodiment comprise casing 110, be arranged on front hand grip 120 on casing 110, back handle 130, ratchet 140 and spring leaf 150 between casing 110 and back handle 130.
Please refer to Fig. 2 and Fig. 3, in back handle 130, be also provided with motor 160.Nested cooperation between casing 110 and back handle 130, casing 110 is inserted in back handle 130 and is fixed on by jackshaft 170 on the output shaft 162 of motor 160.Ratchet 140 is fixed on casing 110.Two ends 152 of spring leaf 150 are positioned at respectively in the groove 132 arranging on back handle 130, and the middle part of spring leaf 150 is provided with the projection 154 of an arc.In projection 154 teeth groove that are bearing on ratchet 140.So, in the time that back handle 130 need to rotate, spring leaf 150 will move under the drive at back handle 130 between the different teeth groove of ratchet 140, thereby reach the object that back handle 130 rotates, after being rotated in place, projection 154 still rests in the teeth groove of ratchet 140, and it is many that the easy to operate and back handle 130 of this mode can rotate the position of stop.In present embodiment, spring leaf 150 has two, is symmetrical arranged about ratchet 140, and spring leaf 150 also can have multiple, evenly arranges or otherwise arrange centered by ratchet 140, and it is more steady that multiple spring leafs 150 can make back handle 130 rotate.Two ends 152 of spring leaf 150 can also be fixed on back handle 130.
Please refer to Fig. 3, between back handle 130 and spring leaf 150, be also provided with the pin 180 being arranged on movably on back handle 130.Pin 180 is connected in the projection 154 of spring leaf 150, thereby projection 154 is limited in the teeth groove of ratchet 140, and back handle 130 is in the lock state.In the time that needs rotate back handle 130, only need to pull pin 180 to move by being arranged on the toggle switch in back handle 130 outsides, just can remove the locking of back handle 130, back handle 130 can be rotated.
In addition, the position that it may be noted that ratchet 140 and spring leaf 150 can exchange, on back handle 130, ratchet structure is set, on casing 110, be also that ratchet structure surrounds spring leaf by spring positioning, can realize equally the object that back handle 130 rotates freely with respect to casing 110.
The front hand grip 120 of present embodiment is to be installed in rotation on casing 110, and it comprises front hand grip shell 122 and is contained in the switch control trigger on front hand grip shell 122.
Please refer to Fig. 4 to Fig. 9, switch control trigger comprises trigger 123, push pedal 124, turning cylinder 125, moving block 126, briquetting 127 and returning spring 128.Push pedal 124, turning cylinder 125, moving block 126 and briquetting 127 are all positioned at front hand grip shell 122, and front hand grip shell 122 is provided with the opening (not label) passing in and out for briquetting 127.
One end of push pedal 124 is rotationally connected by bearing pin 124a and trigger 123, and the middle part of push pedal 124 is provided with rotating spacer pin 124b, and the other end of push pedal 124 is provided with pushing pin 124c.In push pedal 124, be also provided with protuberance 124d, the upper cover of protuberance 124d has the back-moving spring 124e that is bearing on trigger 123, makes push pedal 124 be able to after trigger 123 returns also return smoothly.In front hand grip shell 122, be provided with the baffle plate 122a that is positioned at spacer pin 124b mono-side, to stop spacer pin 124b in the time that trigger 123 is pulled, thereby push pedal 124 rotated while moving following trigger 123 simultaneously taking spacer pin 124b as axle center.Please refer to Fig. 5, in front hand grip shell 122, be also provided with actuator 122b moving up and down.Trigger 123 is provided with chute 123a.One end of actuator 122b is connected in chute 123a, makes to reach and be slidably connected between trigger 123 and actuator 122b.
Please refer to Fig. 4 and Fig. 5, turning cylinder 125 is fixed in front hand grip shell 122.Moving block 126 is rotatably installed on turning cylinder 125.One end of moving block 126 is abutment end 126a, and the middle part of moving block 126 is provided with support portion 126b; The other end of moving block 126 is provided with through hole 126c to be connected with one end of briquetting 127 by bearing pin; Between abutment end 126a and support portion 126b, form breach 126d.The pushing pin 124c of push pedal 124 extend in breach 126d and under the bullet Positive & negative inotropic effect of returning spring 128 with abutment end 126a and keeps tangent original state.Support portion 126b is resisted against actuator 122b in front hand grip shell 122 to limit the initial position of moving block 126.Moving block 126 drives briquetting 127 to stretch out front hand grip shell 122 while rotation, to contact with the mechanism in casing 110, and then turning circuit.Returning spring 128 is enclosed within on briquetting 127, and it can make briquetting 127 returns unclamping after trigger 123.
Please refer to Fig. 4 to Fig. 9, the course of work of switch control trigger is described below.
Fig. 4 is that the state of trigger 123 while not pulled illustrated.
Please refer to Fig. 5, when cocking 123, baffle plate 122a blocks spacer pin 124b, and push pedal 124 is rotated taking spacer pin 124b as axle center to the right, pushing pin 124c acts on abutment end 126a and drives moving block 126 to rotate, and 126 promotion briquettings 127 of moving block stretch out front hand grip shell 122.
Please refer to Fig. 6, when cocking 123, push pedal 124 is followed trigger 123 and is moved left, and pushing pin 124c rotates moving block 126, and 126 promotion briquettings 127 of moving block stretch out front hand grip shell 122.
Please refer to Fig. 7 to Fig. 9, upwards, when upper right or upper left side cocking 123, trigger 123 drives actuator 122b move up (please refer to actuator 122b below arrow upwards), actuator 122b acts on the support portion 126b of moving block 126 and moving block 126 is rotated, and 126 promotion briquettings 127 of moving block stretch out front hand grip shell 122.And in process to the right aforementioned or cocking 123 left, because actuator 122b and trigger 123 are slidably connected, therefore do not affect the motion of trigger 123.
Hence one can see that, all can make briquetting 127 stretch out front hand grip shell 122 to different directions cocking 123.Therefore, the switch control trigger of present embodiment can be realized the object operating in any position of trigger 123, and realizes this purpose only by a link gear, simple in structure.
To sum up, the back handle 130 of present embodiment shrub and hedge trimmer 100 can rotate around casing 110, and the position that rotates conveniently and can rotate stop is many.In addition, the front hand grip 120 of present embodiment shrub and hedge trimmer 100 can operate easily in any position of trigger 123.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
