Referring to Fig. 1, Fig. 5, Fig. 6, Fig. 7, described switch plunger 4 can be connected on electric tool by axis of rotation, institute
State the moving block 5 that pull switch push rod 4 is rotatably connected on switch plunger 4, switch plunger 4, moving block 5 are all set in rotating shaft
On, described moving block 5 is connected by connecting rod 6 with fore trigger 1, and described connecting rod 6 and fore trigger 1 rotate and be connected, described connecting rod 6 with turn
Motion block 5 rotates and connects, and the equal integral type in two ends of described connecting rod 6 is provided with connecting post 17, and connecting post 17 is formed by connecting rod 6 bending, even
Connect post 17 and the connecting hole 18 being coordinated with connecting post 17 all offered on described connecting rod 6, described fore trigger 1, moving block 5,
In connecting post 17 insertion connecting hole 18, connecting post 17 rotates flexibly with respect to connecting hole 18；
Referring to Fig. 1, Fig. 5, Fig. 6, described switch plunger 4 offers the groove 13 accommodating moving block 5, moving block 5 rotates
When moving block 5 and groove 13 side wall interfere and pull switch push rod 4, on described moving block 5 and one end of switch plunger 4 assembling
Integral type is provided with the curved portions 14 that shape of cross section is 1/2 circle, and this curved portions 14 makes moving block 5 with respect to 4 turns of switch plunger
Dynamic flexible, reset convenience；
Referring to Fig. 1, Fig. 3, described middle trigger 2 is rotatably connected on electric tool and pull switch push rod 4, middle trigger
2 can be contacted with switch plunger 4 during pulling, so that can be with pull switch push rod 4 when middle trigger 2 is pulled, such as Fig. 1
Shown, fore trigger 1 rotates clockwise, and drivening rod 6 moves right, and connecting rod 6 moves right and drives moving block 5 rotate counterclockwise,
Now, moving block 5 and the side wall of groove 13 produce interference, and switch plunger 4 rotate counterclockwise certain angle, now, due to only pressing
Lower fore trigger 1, and the moving range of fore trigger 1 e insufficient to the switch 100 making switch plunger 4 touch electric tool, fore trigger 1
When depressing with middle trigger 2 simultaneously, the rotation of middle trigger 2 up time can pull switch push rod 4 rotate counterclockwise, fore trigger 1 with after
Trigger 3 is depressed simultaneously, and the scope of switch plunger 4 rotate counterclockwise becomes big, so that switch plunger 4 touches opening of electric tool
Close 100, open electric tool；
Referring to Fig. 1, Fig. 4, Fig. 8, described rear trigger 3 passes through pull bar 7 pull switch push rod 4, and described pull bar 7 is away from rear trigger
3 one end is provided with the turn of bilge 8 of pull switch push rod 4 when pulling pull bar 7, and described turn of bilge 8 is provided with turn of bilge 8 pull switch push rod
The column 9 contacting with switch plunger 4 when 4, column 9 is integral type structure with pull bar 7, is provided with appearance in described middle trigger 2
Receive the cavity 10 of pull bar 7, described cavity 10 is provided with, away from one end of rear trigger 3, the cavity 11 accommodating turn of bilge 8, described cavity 11 with
Cavity 10 communicates, and is provided with the cooperation turn of bilge 8 when pulling pull bar 7 and pushes pull bar 7 to switch and push away between described cavity 11 and cavity 10
The inclined-plane 12 of bar 4, described rear trigger 3 is provided with the chute 15 with pull bar 7 cooperation, and the length direction of described chute 15 is along pull bar 7
Moving direction setting, on described pull bar 7, integral type is provided with the traveller 16 with chute 15 cooperation, and described traveller 16 is perpendicular to described
Pull bar 7；As shown in figure 1, depressing rear trigger 3 clockwise, pull bar 7 moves right, and now the turn of bilge 8 on pull bar 7 and inclined-plane 12 connect
Touch so that pull bar 7 turns clockwise certain angle, the column 9 on pull bar 7 is contacted with switch plunger 4, pull bar 7 dextrorotation
Pull switch push rod 4 rotate counterclockwise when turning, when only depressing rear trigger 3, the rotating range of rear trigger 3 is insufficient to allow switch plunger
The switch 100 of 4 touching electric tools, therefore, only just can make switch push away when rear trigger 3 is depressed with middle trigger 2 simultaneously
The switch 100 of electric tool touched by bar 4.
With respect to prior art, switch 100 opener of electric tool, structure simply reduces electricity to above-mentioned embodiment
The manufacturing cost of power driven tools, and opener is not easy stuck in use, optimizes the serviceability of opener；
In above-described embodiment, fore trigger 1, rear trigger 3, middle trigger 2 and switch plunger 4 center of rotation on electric tool are not done
Concrete restriction；The i.e. fixation of position on switch plunger 4 for the rotating shaft and the bearing pin on fore trigger 1, rear trigger 3, middle trigger 2
Position does not limit, but should ensure that fore trigger 1, middle trigger 2 or rear trigger 3, middle trigger 2 can promote out when depressing simultaneously
Close the switch 100 that push rod 4 touches electric tool.
In above-described embodiment, the connected mode of switch plunger 4 and spill spin block can also be replaced in the following ways：Described open
Close push rod 4 and be provided with column, during moving block 5 rotation, moving block 5 and column interfere simultaneously pull switch push rod 4, column and moving block 5
For integral type structure.
Switch plunger 4 in above-mentioned embodiment, for mitigating the weight of switch plunger 4, can also open on switch plunger 4
If lightening grooves 20, to mitigate the weight of switch plunger 4, optimize the serviceability of electric tool.
These are only preferred implementation of the present utility model it is intended to embody prominent technique effect of the present utility model and excellent
Gesture, is not the restriction to the technical solution of the utility model.Those skilled in the art will appreciate that all are based on this reality
Modification, change or the substitute technology feature made with new technique content, all should be covered by right appended by this utility model
Require in the technology category of opinion.
