Position relationship is to be described based on orientation shown in the drawings or position relationship, description embodiment merely for convenience with simplified, and
It is not instruction or implies signified device or element there must be specific orientation, with specific azimuth configuration and operation, because
This is it is not intended that to limitation of the present utility model.
Embodiment 1：
As shown in Figures 1 to 7, the present embodiment is a kind of electric tool, specifically a kind of shrub and hedge trimmer, and primary structure includes machine
Shell 1, motor 2 is installed in casing 1, motor 2 is connected with blade assembly 3, for the safety requirement of shrub and hedge trimmer, generally prunes
The casing 1 cut includes front hand grip 11 and back handle 12, an Operation switch is set generally in front hand grip 11, on back handle 12
One Operation switch is set, only simultaneously when two Operation switches are pressed, motor 2 can be just triggered and start, but it is this at present
Biswitch structure is there is also some problems, for example connects up that in disorder, part is more, assembling trouble, and process costs are higher.
The present embodiment is improved to biswitch structure, and the biswitch structure includes the be movably arranged in casing 1
One action bars 4, the second action bars 6, connecting rod 5, starting switch 7, connecting rod 5 be connected to the first action bars 4 and the second action bars 6 it
Between, starting switch 7 is located at the side of connecting rod 5, and using Fig. 2 to Fig. 4 as with reference to if, starting switch 7 is located at the top of connecting rod 5, this
Starting switch 7 in embodiment is microswitch, is connected with the motor 2.
The first action bars 4 is rotatably installed in casing 1 in the present embodiment, and is rotatably installed in front hand grip 11, and
The front end of first action bars 4 is provided with button 41, and at least part of button 41 is emerging in outside casing 1, the first action bars 4 it is another
End, that is, in Fig. 2 to 4 first action bars 4 rear end, be hinged with the front end of connecting rod 5, the rotation of the first action bars 4 and casing 1
Point is located among the front end of the first action bars 4 and the rear end of the first action bars 4, in addition, the front end of the first action bars 4 and casing 1
Between be additionally provided with the first return unit 42, the first return unit 42 is stage clip, for being supplied to the upward restoring force of the first action bars 4.
When the button 41 on the first action bars 4 is pressed down, the first action bars 4 rotates, and the rear end of the first action bars 4 tilts, from
And the front end for stirring connecting rod 5 is moved towards starting switch 7.
The second action bars 6 is also to be rotatably installed in casing 1 in the present embodiment, is specifically rotatably installed in back handle
In 12, the second action bars 6 is a trigger in the present embodiment, and its bottom is emerging in the outside of back handle 12, the second action bars 6
The rear end close to the second operation is located at the run-on point of casing 1, being provided with second between the second action bars 6 and casing 1 in addition resets
Part 62, the second return unit 62 is preferably stage clip, for being supplied to the downward restoring force of the second action bars 6.When the quilt of the second action bars 6
When applying upward power, the rear end that the front end of the second action bars 6 can stir connecting rod 5 is moved towards starting switch 7.
In other words, the first action bars 4 and the second action bars 6 stir connecting rod 5 towards starting switch 7 respectively when being operated
It is mobile, when the first action bars 4 stirs connecting rod 5, the front end of connecting rod 5 is only stirred, when the second action bars 6 stirs connecting rod 5, the only company of stirring
When the rear end of bar 5, the first action bars 4 and the second action bars 6 only one is operated, connecting rod 5 is struck equivalent to only one end,
Connecting rod 5 now will not be triggered to starting switch 7, and when being only struck at the both ends of connecting rod 5, connecting rod 5 can just be triggered to and open
Dynamic switch 7, this frame mode parts are fewer, it is not necessary to other parts, and also technique is simpler when assembling
It is single.
In the utility model, the junction of second action bars 6 and connecting rod 5 is provided with chute 61, is the specifically
The front end of two action bars 6 sets chute 61, and rotating shaft 51 is set in the rear end of connecting rod 5, and rotating shaft 51 is slidably fitted in chute 61, if
The advantages of putting chute 61 is that one section of idle stroke can be provided, it is possible to achieve the first action bars 4 and the second action bars 6 are separate
Do not interfere, if being not provided with chute 61, the displacement that the first action bars 4 stirs the end of connecting rod 5 is very limited, the first operation
Bar 4 wants to stir connecting rod 5 close to starting switch 7, certainly will be drawn to the generation activity of the second action bars 6 so that two action bars
Can not good independent operating.
And after chute 61 is set, it may refer in Fig. 3, after the first action bars 4 stirs connecting rod 5, the meeting of rotating shaft 51 of connecting rod 5 exists
Moved backward in chute 61, it is one section of idle stroke for the second action bars 6 that this section mobile, does not interfere with the second action bars
6 movement, that is, after setting chute 61, relative displacement occurs for the action bars 6 of connecting rod 5 and second, so as to so that the first action bars 4
After being operated, the second action bars 6 is not towed itself completely.
Equally, referring in Fig. 4, when the second action bars 6 is operated, the rear end of connecting rod 5 is stirred, the meeting of rotating shaft 51 of connecting rod 5 exists
It is moved along in chute 61, i.e., relative displacement occurs for the action bars 6 of connecting rod 5 and second, so that the second action bars 6 is operated
Afterwards, the first action bars 4 is not also towed itself.
Simultaneously using after chute 61, connecting rod 5 and one end that the first action bars 4 is connected can be struck farther distance,
That is set chute 61, not only realize the first action bars 4 and the second action bars 6 both when being operated between each other not by
Interference, draw, and the distance that connecting rod 5 is struck can also be improved.
On connecting rod 5, the first action bars 4, the second action bars 6 other concrete structures, reference can be made to Fig. 6 and Fig. 7, this implementation
Example in connecting rod 5, its top be provided be used for contact starting switch 7 contact projection 52, setting contact projection 52, facilitate connecting rod 5
Starting switch 7 is touched, prevents other position false touches of connecting rod 5 from encountering starting switch 7；
In addition as shown in fig. 7, the second action bars 6 is provided with the second U-lag 63 in the present embodiment, the two of the second U-lag 63
Individual side wall is respectively equipped with chute 61, and chute 61 is in waist type groove, certainly in other embodiments, the shape of chute 61 in the present embodiment
Shape can be rectangle, arc etc., and the both sides of the rear end of connecting rod 5 are correspondingly arranged two rotating shafts 51, the side of the second U-lag 63 respectively
Wall is provided with the second guiding surface 64 in the top of chute 61, and in assembling, two rotating shafts 51 of connecting rod 5, which are contacted to second, to be oriented to
On inclined-plane 64, so that two side walls of the second U-lag 63 extend out deformation, so that two rotating shafts 51 snap onto chute 61
It is interior.
Similarly, the first action bars 4 is provided with the first U-lag 43, and the front end of connecting rod 5 is hinged on two of the first U-lag 43
Between side wall, two side walls of the first U-lag 43 are provided with hinge hole 44, and the side wall of the first U-lag 43 is in the upper of hinge hole 44
Side is provided with the first guiding surface 45, and in assembling, the jointed shaft on the rear end of connecting rod 5 is snapped onto by the first guiding surface 45
In hinge hole 44.
