Detailed description of the invention
Please refer to the drawing 1 with shown in Fig. 2, the electric tool of present embodiment comprise renovate 10, be positioned at renovate fixture 20 below 10, for install renovate 10 rotating shaft 30, the out-of-work button 40 of electric tool can be made and be installed on respectively renovate 10, a pair sensing element on fixture 20.A pair sensing element can be referred to as inductive component.In the present embodiment, sensing element comprise magnetic part 50 and with sensor 60.In the present embodiment, magnetic part 50 is magnet.In other embodiments, button 40 is not limited to the function that quits work of electric tool, can for opening any button renovating 10.
Renovating 10 is a platy structure extending longitudinally, and its surface has certain radian.Renovate the rotating hole 11 that 10 settings are positioned at its rear end, rotating shaft 30 is through rotating hole 11, and renovating 10 can around rotating shaft 30.Renovate 10 also to comprise and be positioned at its front end and for the snap fit 12 with the mutual clamping of stop button 40, snap fit 12 comprises from renovating 10 surfaces to the connecting portion 121 of downward-extension and the Access Division 122 that extends to stop button 40 direction from connecting portion 121.Access Division 122 is for fastening the lower surface of stop button 40.Can provide an elastic component (not shown) renovating between 10 and rotating shaft 10, be not subject to External Force Acting when renovating 10, elastic component can be upspring renovating 10, makes to renovate 10 and is in tip-up state.Operator can be reduced like this and stir the action of renovating 10.
Renovate 10 be also provided with the accepting groove 14 that is positioned at its lower surface and from its lower surface to the extending column 13 of downward-extension, accepting groove 14 is positioned at the centre position of extending column 13, and wherein, accepting groove 14 is for accommodating part sensing element, in the present embodiment, the sensing element be contained in accepting groove 14 is magnet 50.Certainly, in other embodiments, accepting groove 14 is not limited to the centre position of extending column 13, can be positioned at some other positions of renovating on 10, as long as the accepting groove 14 arranged can be used in accommodating magnet 50.
Fixture 20 is a part of structure of electric tool, fixture 20 is provided with another sensing element interactional with magnet 50, and in the present embodiment, the sensing element be positioned on fixture 20 is sensor 60, when renovating 10 and closing, sensor 60 is positioned at immediately below magnet 50.Whether the position judgment carrying out induced magnet 50 by sensor 60 is renovated 10 and is dug, when renovate 10 be closed on, sensor 60 can sense magnet 50, so can judge that renovating 10 is in closure state, thering is provided to described electric tool can the instruction of trouble free service, the parameter of electric tool or the current electric tool of effective reflection can be started, if renovate 10 to be in tip-up state, so sensor 60 cannot sense the position of magnet 50, sensor 60 provides to electric tool and is in dangerous instruction at present, the parameter work of enabled instruction or the setting according to current electric tool can not be provided electric tool, now the start-up circuit of electric tool disconnects or the disconnection of transformation parameter command link, electric tool or can not according to current parameter work cannot be started.
In other are implemented, according to sensor in the present embodiment 60 and the interactional principle of magnet 50, inductive component can be replaced by the sensing element of other types, as: contact switch, capacitance component, resistor assembly, Inductive component etc.As arranged a contact switch respectively renovating 10, on fixture 20, when two contact switch contacts, can electric tool be started, when two contact switch do not contact, cannot electric tool be started; Or a capacitance component or resistor assembly or Inductive component are set respectively renovating 10, on fixture 20, when two capacitance components or resistor assembly or Inductive component interact, electric tool can be started, when two capacitance components or resistor assembly or Inductive component do not interact, electric tool cannot be started.
When renovating 10 and being closed, the sensing element on fixture 20 detects the sensing element renovated on 10, causes the parameter that can start electric tool or the current electric tool of effective reflection, according to the parameter work arranged at present; When renovating 10 and opening, the sensing element on fixture 20 can not detect the sensing element renovated on 10, causes the parameter that can not start electric tool or can not reflect current electric tool, the parameter work that can not show according to current electric tool.Therefore, renovating the sensing element 10 and fixture 20 being arranged respectively mutual induction, cause and just can only can make electric tool work when renovating 10 and being closed, avoid because of the parameter button on careless shake-up electric tool or start button, and the unexpected phenomenon occurred.
Stop button 40 comprises the adjutage 41 to renovating 10 directions extensions, and adjutage 41 matches with snap fit 12, and the Access Division 122 of snap fit 12 is connected in the lower surface of adjutage 41, and adjutage 41 prevention is renovated 10 and popped up.When pressing stop button 40 downwards, snap fit 12 and adjutage 41 depart from mutually, and renovate 10 and pop up, operating personnel can carry out optimum configurations to electric tool.
When renovating 10 and digging, in any case regulate the parameter being positioned at any button renovated below 10, even if encountered start button because of carelessness, electric tool can not start, only have when renovating 10 and closing, when sensor 60 has sensed magnet 60, electric tool could start or according to the parameter work arranged at present.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
