Abstract
The invention discloses a double-action switch structure which is applied to gardening tools and motor assemblies connecting the gardening tools. The double-action switch structure comprises a guide feeler lever, a first action part which drives the guide feeler lever to move in the first direction, a second action part which drives the guide feeler lever to move in the second direction intersected with the first direction, and a switch which can be triggered after the guide feeler lever moves in the first direction and the second direction. The first action part and the second action part drive the guide feeler lever respectively, enable the guide feeler lever to move in the first direction and the second direction, and then trigger the switch, and double action can be achieved though only one switch. The double-action switch structure has a few of arranged wires, and is simple, convenient to assemble and lower in cost. Further, the cost of the pruner with the double-action switch structure is lower.

Move in a second direction after 1534 drivings, but do not move along the first direction, namely lead feeler lever 151 to up movement not backward
Movement has gap so that leading between the contact 1513 of feeler lever 151 and conductive part 1541.Contact 1513 does not act on to conductive part 1541
It is impossible to make switch 154 conducting, switch 154 is off power.
The double step switch structure 150 of present embodiment must press the first button 1523 and the second button 1533 just can make out
Close connection.No matter first press the first button 1523 or the second button 1533 or press simultaneously and all can realize driving and lead feeler lever
151 conducting switches.When two buttons are pressed simultaneously, the first button 1523 will lead feeler lever 151 toward pusher, and the second button 1533 will
Lead feeler lever 151 up to push up so that switch 154 turns on.Press the second button 1533 in the ban and press the first button 1523 again, due to second
Button 1533 has been given and has been led feeler lever 151 with certain spacing, leads feeler lever 151 and withstands switches conductive under the first button 1523 thrust
Portion 1541 makes switch 154 conducting.Press the first button 1523 in the ban and press the second button 1533 again, due to the first button 1523
Make through to leading feeler lever 151 with certain spacing, leading feeler lever 151 and withstanding switches conductive portion 1541 under the second button 1533 pressure
Switch 154 conducting.
Second contact site 1512 be inclined-plane setting, the second drive division 1534 also be relative set inclined-plane, and with level
In the inclined plane at an acute angle of face, there is certain length.Be arranged such, no matter the second button 1533 first press or after press all
The second drive division 1534 can be made to contact with the second contact site 1512.By arranging limiting section in housing 110（Not shown）Deng side
Method to lead feeler lever 151 arrange certain spacing so that only moving in certain width range.After feeler lever 151 is led in setting, this reality
150, double step switch structures applying mode need to arrange one and switch, and wiring is few, and structure is simple, easy to assembly, from forming
This is relatively low, and makes the pruner 100 with this pair of step switch structure 150 also can reduces cost.Double step switch structures 150 are fitted
For garden instrument, such as pruner 100 and chain saw（Not shown）Deng.
Embodiment described above only have expressed the several embodiments of the present invention, and its description is more concrete and detailed, but simultaneously
Therefore the restriction to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, some deformation can also be made and improve, these broadly fall into the guarantor of the present invention
Shield scope.Therefore, the protection domain of patent of the present invention should be defined by claims.
