Specific embodiment

It please join shown in Fig. 1 and Fig. 2, the electric tool of present embodiment includes flip lid 10, the fixation positioned at 10 lower section of flip lid Part 20, for install flip lid 10 rotary shaft 30, electric tool can be made to stop working button 40 and be respectively arranged in flip lid 10, a pair of of sensing element on fixing piece 20.A pair of of sensing element can be collectively referred to as inductive component.In the present embodiment, sensing element Including magnetic part 50 and with sensor 60.In the present embodiment, magnetic part 50 is magnet.In other embodiments, the not office of button 40 It is limited to the function that stops working of electric tool, can is any button of unlatching flip lid 10.

Flip lid 10 is a plate structure longitudinally extended, and surface has certain radian.10 setting of flip lid is located at thereafter The rotating hole 11 at end, rotary shaft 30 pass through rotating hole 11, and flip lid 10 can be around rotary shaft 30.Flip lid 10 further includes being located at its front end And the hook 12 for being mutually clamped with stop button 40, hook 12 include the interconnecting piece 121 extended downwardly from 10 surfaces of flip lid And the clamping portion 122 extended from interconnecting piece 121 to 40 direction of stop button.Clamping portion 122 is for clasping under stop button 40 Surface.An elastic component (not shown) can be provided between flip lid 10 and rotary shaft 10, when flip lid 10 is not affected by external force, bullet Property part flip lid 10 can be bounced so that flip lid 10 be in tip-up state.Operator can be reduced in this way stirs the dynamic of flip lid 10 Make.

Flip lid 10 is additionally provided with container 14 and the extending column 13 that extends downwardly from its lower surface positioned at its lower surface, receives Tank 14 is located at the middle position of extending column 13, wherein container 14 is used for collecting part sensing element, in the present embodiment, receives The sensing element being dissolved in container 14 is magnet 50.Certainly, in other embodiments, container 14 is not limited to extending column 13 Middle position, can be located at flip lid 10 on some other positions, as long as setting container 14 can be used in accommodate magnetic Iron 50.

Fixing piece 20 is a part of structure of electric tool, is provided on fixing piece 20 another with the interaction of magnet 50 One sensing element, in the present embodiment, the sensing element on fixing piece 20 is sensor 60, when flip lid 10 closes, is passed Sensor 60 is located at the underface of magnet 50.Judge whether flip lid 10 is dug by sensor 60 come the position of induced magnet 50, when Flip lid 10 is in closure, and sensor 60 can sense magnet 50, then can be determined that flip lid 10 in closed state, to described Electric tool offer can be can star electric tool or effectively be reflected the ginseng of current electric tool with the instruction of trouble free service Number, if flip lid 10 is in tip-up state, sensor 60 can not sense the position of magnet 50, and sensor 60 gives electronic work Tool provides and is currently in dangerous instruction, cannot provide electric tool enabled instruction or according to the setting of current electric tool Parameter work, at this time electric tool start-up circuit disconnect or configured transmission command link disconnect, electronic work can not be started Tool cannot work according to current parameter.

In other implementations, the principle to be interacted according to sensor 60 in the present embodiment and magnet 50, inductive component can To be replaced by other kinds of sensing element, such as: contact switch, capacitance component, resistor assembly, Inductive component etc..Such as renovating 10, a contact switch is respectively set on fixing piece 20, when two contact switch contact, can star electric tool, when two When a contact switch does not contact, it is not possible to start electric tool;Or a capacitor is respectively set on flip lid 10, fixing piece 20 Perhaps Inductive component interacts when two capacitance components or resistor assembly or Inductive component for component or resistor assembly When, it can star electric tool, when two capacitance components or resistor assembly or Inductive component do not interact, it is not possible to Start electric tool.

When flip lid 10 is closed, the sensing element on fixing piece 20 detects the sensing element on flip lid 10, and causing can be with Starting electric tool or the parameter for effectively reflecting current electric tool, work according to the parameter being arranged at present;When flip lid 10 When opening, the sensing element on fixing piece 20 cannot detect the sensing element on flip lid 10, cause that electric tool cannot be started Or cannot reflect the parameter of current electric tool, it cannot be worked according to the parameter that current electric tool is shown.Therefore, it is renovating 10 and fixing piece 20 on the sensing element of mutual induction is respectively set, Shi Caineng can only be closed in flip lid 10 by, which causing, make electric tool Work, avoid because accidentally touch electric tool on parameter button or start button, and appearance unexpected phenomenon.

Stop button 40 includes the adjutage 41 extended to 10 directions of flip lid, and adjutage 41 is matched with hook 12, hook 12 clamping portion 122 is connected in the lower surface of adjutage 41, and adjutage 41 prevents flip lid 10 from popping up.Stopping is pressed when downward Button 40, hook 12 are mutually disengaged with adjutage 41, and flip lid 10 pops up, and operator can carry out parameter to electric tool Setting.

When flip lid 10 is dug, the parameter for being located at any button of 10 lower section of flip lid is adjusted anyway, even if accidentally Start button is encountered, electric tool can not start, and only when flip lid 10 closes, sensor 60 has sensed magnet 60 When, electric tool could start or work according to the parameter being arranged at present.

The embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously Limitations on the scope of the patent of the present invention therefore cannot 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, various modifications and improvements can be made, these belong to guarantor of the invention Protect range.Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
