Technical field
The present invention relates to a kind of Multi-head electric tool, particularly relate to and a kind ofly make user can the Multi-head electric tool of switch operating state fast.
Background technology
Garden instrument is due to its bulky feature, when needing to carry out the switching of instrument according to different operating modes, very inconvenient, but Multi-head electric tool solves this problem.Current Multi-head electric tool on the market generally adopts the collocation form of main body+pick-off gear casing+interchangeable working head, namely based on main body, collocation has multiple different working head, to adapt to the needs of different working environments, different working heads has different rated speeds, therefore also needs multiple different gear housing of arranging in pairs or groups.Although this technical scheme solves the trouble of diverter tool to a certain extent, but due to the important component part that gear housing is in this technical scheme, its volume and weight are also very large, and user still needs time and the energy of at substantial when changing.
Summary of the invention
The object of this invention is to provide a kind of can the Multi-head electric tool of switch operating state fast.
For achieving the above object, the technical solution used in the present invention is: a kind of Multi-head electric tool, comprise fuselage, be located at the motor on described fuselage, multiple working heads that can be in transmission connection with the output shaft of described motor respectively, multiple described working head works when described output shaft reaches corresponding setting speed respectively, described Multi-head electric tool also comprises the speed regulator for regulating described output shaft rotating speed, described speed regulator has multiple speed-regulating mode, the described setting speed one_to_one corresponding of described output shaft when the rotating speed of described output shaft and multiple described working head work under multiple described speed-regulating mode, described fuselage is also provided with the regulating element for switching multiple speed-regulating modes of described speed regulator.
Preferably, described regulating element is the speed disk that can rotate around its axial line, and described speed disk has multiple gear, and multiple described gear distributes separately along the circumference of described speed disk, multiple described gear and multiple described speed-regulating mode one_to_one corresponding.
Preferably, described regulating element is multiple button, multiple described button and multiple described speed-regulating mode one_to_one corresponding.
Further preferably, described multiple working head at least comprises working head for mowing grass.
Further preferably, described multiple working head at least comprises chain saw working head.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages: when user needs switching working mode, only needs to pull down old working head, install new working head, by operation regulating element, change motor speed, reach the maximum efficiency of new working head; Replacing gear-box before replacing with operation regulating element, brings facility to user.

Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, technical scheme of the present invention is further elaborated.
See the overall schematic of the Multi-head electric tool shown in accompanying drawing 1, that includes fuselage 1, fuselage 1 is in elongated rod shape, and be wherein link 2 near the one end on ground, link 2 place is provided with motor 4, motor 4 has motor shaft, for connecting different working heads, for each working head, there is the setting speed that corresponding, namely, when motor 4 equals this setting speed, this working head is in maximum operating efficiency value; Fuselage 1 inside is provided with speed regulator (not shown in FIG.), for controlling the voltage at motor two ends when Multi-head electric tool works, motor 4 is made to obtain above-mentioned setting speed, and then the efficiency making instrument reach the highest, in specific embodiment, described speed regulator have employed rheostat, and the voltage being controlled motor two ends by the size changing electric tool internal resistance finally changes rotating speed, makes current motor rotating speed identical with setting speed; Rheostat is provided with multiple alternative resistance sizes, is also multiple speed-regulating mode; With speed regulator accordingly, be provided with regulating element 3 on the fuselage 1, here preferred regulating element 3 is arranged on fuselage 1 one end away from ground, be convenient to user's operation, regulating element 3 is provided with the multiple gear corresponding with multiple speed-regulating modes of described speed regulator or button, design according to 6 speed-regulating modes in embodiment, represent with alphabetical A-F in accompanying drawing 2 and 3.In the actual production of product, can on the gear of the different speed-regulating modes of regulating element 3 or button, the pattern of the different operating head that printing is corresponding or electric tool, makes user identify different speed-regulating mode more easily.
Accompanying drawing 2 is the first embodiment of regulating element 3, is employed herein the form of speed disk 31, and speed disk 31 is slit into according to the quantity average mark of operation range that several are fan-shaped.Because the present embodiment devises 6 kinds of operation range, therefore speed disk 31 is divided into 6 60 degree fan-shaped.Speed disk 31 can rotate around its axial line, and speed disk side is also provided with arrow 32, when arrow 32 point to certain fan-shaped time, the size that the mode of operation that the internal resistance of Multi-head electric tool is just set to corresponding with current gear is mated.Accompanying drawing 3 is the second embodiment of control element, be employed herein the form of button 33, direct and 6 button one_to_one corresponding by 6 speed-regulating modes, when pressing certain button, the internal resistance of Multi-head electric tool is just set to the resistance sizes of mating with current speed-regulating mode.The essence of above accompanying drawing 2 and two embodiments described in accompanying drawing 3 is that 6 gears of regulating element 3 or the button resistance sizes different from 6 of speed regulator defines one-to-one relationship.
Accompanying drawing 4 and accompanying drawing 5 are sectional views that Multi-head electric tool changes two kinds of different operating heads.Accompanying drawing 4 correspondence be grass-mowing machine mode of operation, the working head of its correspondence is working head for mowing grass 5, and working head for mowing grass 5 can be beat the grass rope or plastic blade, and transmission is installed on the output shaft of motor 4, baffle plate 6 can also be installed again in addition, to prevent grass bits splashes.Accompanying drawing 5 correspondence be chain saw mode of operation, the working head of its correspondence is chain saw working head 7, and equally, chain saw working head 7 is in transmission connection with the output shaft of motor 4.The mode of operation of Multi-head electric tool includes but not limited to above two kinds, as long as the working head driven by electric machine rotation can with on the invention, working head of such as pruning, work of loosening the soil are first-class.No matter be any mode of operation, all should after determining its setting speed, by the internal resistance size of correspondence and the gear of regulating element 3 or button one_to_one corresponding.
After implementing above technical scheme, Multi-head electric tool, only needs regulating element 3 to be switched to corresponding speed-regulating mode without the need to synchronously changing the gear-box of its correspondence again when changing working head, time saving and energy saving.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
