Specific embodiment
Below with reference to embodiment shown in the drawings, the present invention will be described in detail.But these embodiments are simultaneously unlimited
The system present invention, the transformation in structure or function that those skilled in the art are made according to these embodiments include
Within the scope of the present invention.
Fig. 1 is the schematic diagram of the synchronization system of combination tool of the present invention, please refers to Fig. 1.The synchronization system 100 of combination tool
The synchronization of use state for combination tool, the synchronization system 100 of combination tool include adaptive device 110, the first electronic work
Tool 120 and the second electric tool 130.Adaptive device 110 includes connector 111 and sensor 112, and sensor 112 is wirelessly connected
In the second electric tool 130, there is the radio receiver (not shown) corresponding to sensor 112 in the second electric tool 130,
The transmitting of information, the second electric tool are realized between the mode and the second electric tool 130 of the communication of 112 available wireless of sensor
130 can make further according to the information received and be adaptively adjusted, for example, booting or shutdown.And connector 111 can be with sensor
112 integrated designs；Or two elements can also be independent, the row assembling again both when using.
Sensor 112 can be removably attached on the first electric tool 120 by connector 111.Herein, the first electricity
Power driven tools 120 do not need special matching design to cooperate the removable attachment of 112 upper connector 111 of sensor, that is, sense
The connector 111 that device 112 is only equipped with by itself can be realized and the attachment of the first electric tool 120.In this way, sensor 112
Can and different the first electric tool 120 realize and be attached, do adaptability design without the first electric tool 120, can be significantly
Ground increases the scope of application and convenience of sensor 112, for example, the first electric tool 120 can be different types of electronic work
The same type electric tool of tool or different manufacturers.And it will be situated between in detail below about the different embodiments of connector 111
It continues.
After sensor 112 attaches on the first electric tool 120, sensor 112 detects the first electric tool first
120 use state, then again by use state information wireless transmission to the second electric tool 130, the second last electric tool
130 are synchronized with the use state of itself according to received status information the use state of the first electric tool 120.I.e. when first
When the booting operation of electric tool 120, sensor 112 detects this status information and to be wirelessly transmitted to second electronic of being switched on
Tool 130, the second electric tool 130 also according to synchronization enter open state, shutdown.In this way, detecing by sensor 112
Survey the state synchronized that the synchronization system 100 of combination tool can be realized with transmitting.
In this present embodiment, sensor 112 is wirelessly connected in the second electric tool 130, i.e. sensor 112 need to be with the second electricity
Power driven tools 130 are used cooperatively, and in practical operation, are generally sold the two as a whole, electronic work as shown in Figure 1
Tool system 200.In this present embodiment, the second electric tool 130 is, for example, dust catcher, and adaptive device 110 is i.e. electronic as second
The matched attachment of institute carries out whole sell on tool 130 (such as dust catcher).In this way, when needing as the second electric tool 130
(such as dust catcher) is combined with other electric tools (the first electric tool 120 is, for example, sanding machine, grass trimmer or cutting machine) to be made
Used time can removably assemble matched adaptive device 110 with other electric tools (such as first electric tool 120).
The connector 111 for recycling adaptive device 110, does not need the connector that cooperation is arranged on other electric tools, adaptive device 110
It can be combined from different electric tools, to realize the effect synchronous with other electric tools of electric tool system 200.
Certainly, the number end of adaptive device 110 is depending on the use demand of user, for example, it is desired to the second electric tool 130
When being applied in combination simultaneously with multiple first electric tools 120, it is possible to use multiple adaptive devices 110.Multiple first electric tools
120 are attached adaptive device 110, right as long as have the first electric tool 120 starting in multiple first electric tools 120
After answering its sensor 112 to send status information to the second electric tool 130, the second electric tool 130 starts, for another example
When the first only all electric tools 120 is turned off, the second electric tool 130 is just closed, and when is started and when is closed, end view
The demand of client and be arranged.
And the specific embodiment about connector 111, be specifically described below: Fig. 2 is the one of inventive sensor
