With reference to shown in Fig. 2 and Fig. 3, the present invention relates to a kind of electric hand tool, for Multi Role Aircraft 100 in present embodiment, including battery bag 110, housing 120, the motor (not shown) being arranged in housing 120 and eccentric gearing structure 130, by the eccentric drive mechanism 130 output shaft 140 with action oscillating traverse motion, the work 150 that driven by output shaft 140.
Eccentric gearing structure 130 includes eccentric shaft 131, eccentric part 132 and shift fork 133.
Please continue to refer to Fig. 4, eccentric shaft 131 eccentric setting is on the end face of the motor shaft 10 of motor, and namely the centrage b-b of the centrage a-a of eccentric shaft 131 and motor shaft 10 is at intervals.Eccentric part 132 be shaped as round platform, the end of eccentric shaft 131 is through the middle part of eccentric part 132.Shift fork 133 be shaped as U-shaped, have bottom 133a and two adjutage 133b.The bottom of shift fork 133 is fixing with output shaft 140 to be connected, and two adjutage 133b are oppositely arranged, and abut with the circumference of eccentric part 132.
During motor work, drive motor axle 10 rotates, and motor shaft 10 drives eccentric shaft 131 to circle.When eccentric shaft 131 drives the left side adjutage 133b of eccentric part 132 overall deflection shift fork 133, the overall left avertence of shift fork 133；In like manner, as eccentric part 132 overall deflection the right adjutage 133b, the overall right avertence of shift fork 133.Deflecting of shift fork 133 drives output shaft 140 to do oscillating traverse motion around the own axes of output shaft 140, thus driving work 150 to make.
Refer to Fig. 5, housing 120 caves in enclosure interior away from one end of work 150, forms battery compartment 121, the shape of battery compartment 121 and the mating shapes of battery bag 110, is used for holding battery bag 110.The bottom of battery compartment 121 is provided with at least two power end 122.Described power end 122 is laminar plug-in unit.
The axis c-c of output shaft 140 is vertical with the first plane 160, and the extension plane of power end 122 is parallel with the first plane 160, also parallel with the direction of the oscillating motion of Multi Role Aircraft 100.When Multi Role Aircraft 100 works, under work 150 effect of inertia swung, housing 120 also correspondingly swings, and the power end 122 in drive battery compartment 121 swings also with the direction of oscillating motion.
Please also refer to Fig. 6 and Fig. 7, battery bag 110 has at least two electrode slice 111, some first battery units 112 and circuit board 113.
Some first battery unit 112 parallel stacks build up set of cells 114.In present embodiment, three the first battery units 112 are stacked into set of cells 114, and axis d-d and three first battery unit 112 of set of cells 114 is parallel, and set of cells 114 side vertical with axis d-d is triangular in shape.
Circuit board 113 is arranged on the triangle side of set of cells 114, it is possible to set of cells 114 overcharges/Cross prevention, and gathers the temperature signal of battery bag 110, voltage signal or charging and discharging state signal etc..
Electrode slice 111 is welded on circuit board 113, including anelectrode, negative electrode and some pickup electrodes.Anelectrode, negative electrode are used for exporting energy to Multi Role Aircraft 100, and some pickup electrodes are used for temperature signal, voltage signal or the charging and discharging state signal etc. that export in battery bag 110.
The standard output voltage of every batteries unit is approximately 3.6V, and the output voltage of described battery bag 110 is approximately 10.8V.
Further, battery bag 110 includes three the first battery units 112 and second battery unit 115.Three the first battery units 112 are stacking triangular in shape, and the second battery unit 115 overlays on the end face of the first battery unit 112.The rest of the end face of three the first battery units 112 forms a platform 116.Described electrode slice 111 is positioned on platform 116.
The standard output voltage of every batteries unit is approximately 3.6V, and the output voltage of described battery bag 110 is approximately 14.4V.
In present embodiment, electrode slice 111 includes the first electrode slice 111a and the second electrode slice 111b, first electrode slice 111a and the second electrode slice 111b all includes the metal burst 117 that at least two is oppositely arranged, and is formed and form the second long narrow gap 118b between the two metal bursts 117 of long narrow the first gap 118a, the second electrode slice 111b between the two metal bursts 117 of the first electrode slice 111a.When battery bag 110 is encased in battery compartment 121, power end 122 is inserted respectively in the gap of the electrode slice 111 of correspondence, contacts so that power end 122 is stable with electrode slice 111.
The bearing of trend of the second gap 118b of the first gap 118a and the second electrode slice 111b of the first electrode slice 111a is parallel with the first plane 160, also parallel with the direction of the oscillating motion of described Multi Role Aircraft 100, and the bearing of trend of the first gap 118a and the second gap 118b is vertical with the axis d-d of battery bag 110.
