First embodiment electric tool 100 as shown in Figure 1 is specially a kind of polishing machine, and polishing machine can be used for polishing, beating
The operations such as mill, waxing.
For convenience of explanation, upside, downside, left side, right side, front side and the rear side in Fig. 1 shown in arrow are also defined.
As shown in Figures 1 to 4, electric tool 100 includes：Housing 11, motor 12, output shaft 13, executive item 14 and battery
Bag 15, wherein, motor 12 includes the motor shaft 121 that can be rotated with electrical axis 101 for axis.For polishing machine, the execution
Part 14 is specifically as follows chassis, and chassis has baseplane 141.
Housing 11 includes the first receiving portion 111 and the second receiving portion 112, and the first receiving portion 111 is along 101 direction of electrical axis
Extension, motor 12 are arranged in the space that the first receiving portion 111 surrounds.First receiving portion 111 includes being used to supply user
The handle 111a of gripping.Second receiving portion 112 is arranged on one end of the first receiving portion 111, overall, the first receiving portion
111 and second receiving portion 112 form entirety it is L-shaped.Output shaft 13 be at least partially disposed in the second receiving portion 112 surround and
Into space in.Housing 11 further includes the engaging portion 113 for battery pack 15 to be bound to housing 11, engaging portion 113 and second
Receiving portion 112 is separately positioned on the first receiving portion 111 along the both ends on 101 direction of electrical axis, in this way, handle 111a is positioned at electricity
Between pond bag 15 and output shaft 13, so that the center of gravity of complete machine is located at handle 111a, so that user can be more stable
The operation electric tool 100.
One end that motor 12 exports power is set close to output shaft 13, and output shaft 13 can be rotated with exporting axis 102 for axis,
Output axis 102 is mutually perpendicular to electrical axis 101.In order to realize the commutation of power, motor shaft 121 forms or is connected with
One travelling gear 122, output shaft 13 form or are connected with the second travelling gear 131, the first travelling gear 122 and the second transmission
Gear 131 cooperates, so that the power that motor 12 is exported is transferred to output shaft 13.
Output shaft 13 is used to drive executive item 14 to perform instrumental function, for polishing machine, as shown in figure 5, output shaft
13 are also formed with opposite 102 eccentric eccentric part 132 of output axis, and eccentric part 132 coordinates with the transmission of executive item 14.
For polishing machine, the baseplane 141 of executive item 14 also is normal to output axis 102, electrical axis 101 and bottom
Plane 141 is parallel to each other, and motor 12 can drive chassis to be rotated using an axis perpendicular to baseplane 141 as axis, so as to fulfill throwing
The function of light.
The part that first receiving portion 111 forms handle 111a is also symmetrical arranged on a symmetrical plane 103, this is symmetrical flat
Intersect identified plane with electrical axis 101 and output axis 102 and be parallel to each other or overlap in face 103.Handle 111a's
Downside is also provided with for controlling the switch 16 of motor 12 for user's operation.
Battery pack 15 is used to power to motor 12, and battery pack 15 is also formed with housing 11 and is detachably connected.When battery pack 15
When being bound to housing 11 by engaging portion 113, battery pack 15 is located at the rear side of the first receiving portion 111.
Specifically, as shown in Figure 6 and Figure 7, engaging portion 113 is formed with for being oriented to battery pack 15 along first straight line 104
Direction is bound to the guide frame 113a of housing 11, and guide frame 113a is specifically as follows guiding rib, corresponding, battery pack 15
Formed with the fit structure 151 coordinated with guide frame 113a.Wherein, battery pack 15 is bound to the first straight line 104 of housing 11
Direction also is normal to output axis 102 and perpendicular to electrical axis 101, in other words, relative to whole electric tool 100
Speech, battery pack 15 in left-right direction horizontal integration to housing 11.For polishing machine, battery pack 15 is bound to the of housing 11
One straight line, 104 direction is perpendicular to plane determined by output axis 102 and electrical axis 101, in this way, when user is gripped by first
During the handle 111a that receiving portion 111 is formed, battery pack 15 will not be pointed to the hand and hand of the user of the upside of the first receiving portion 111
Arm causes to interfere, moreover, the surface that battery pack 15 will not be pointed to the workpiece of the downside of the first receiving portion 111 causes to interfere.It is right
For polishing machine, 104 direction of first straight line that battery pack 15 is bound to housing 11 is also parallel with baseplane 141, so that in electricity
The workpiece that will not be pointed under baseplane 141 after 15 inserting to housing 11 of pond bag causes to interfere.
Still further, battery pack 15 has length direction, width and short transverse, and battery pack 15 is in length side
Upward size is more than its size in the direction of the width and more than its size in the height direction.Wherein, 15 edge of battery pack
Its length direction is bound to housing 11, and in other words, the length direction of battery pack 15 and battery pack 15 are bound to the of housing 11
One straight line, 104 direction is parallel to each other, in this way, after battery pack 15 is bound to housing 11, the length of the size maximum of battery pack 15
Direction is set in the lateral direction, and the length direction of battery pack 15 at this time is also vertical with above-below direction, this way it is possible to avoid electric
Pond bag 15 causes to interfere in operation and workpiece of the size to user of length direction, even if also saying, is bound in battery pack 15
After on housing 11, the relatively small width of size is set along the vertical direction, so because battery pack 15 is in width
Size is relatively small, so that the hand of handle 111a will not be gripped to user or arm cause to interfere, will not with positioned at battery
The workpiece interference of the downside of bag 15.
Specifically, battery pack 15 is after housing 11 is bound to, and battery pack 15 is along the size L1 on 102 direction of output axis
More than or equal to 60mm and it is less than or equal to 90mm, furthermore, battery pack 15 is more than along the size L1 on 102 direction of output axis
Equal to 60mm and it is less than or equal to 80mm, in other words, the size L1 of battery pack 15 in the direction of the width is more than or equal to 60mm and small
In equal to 90mm.Still further, along 102 direction of output axis, battery pack 15 is protruding upward in the portion of handle 111a
The size L2 divided is more than or equal to 0 and is less than or equal to 50mm, and furthermore, battery pack 15 is protruding upward in the part of handle 111a
Size L2 be more than or equal to 0 and be less than or equal to 25mm.For polishing machine, the point nearest apart from baseplane 141 of battery pack 15
The distance between baseplane 141 is more than or equal to 10mm and is less than or equal to 85mm, and furthermore, battery pack 15 is apart from baseplane
The distance between 141 nearest points and baseplane 141 are more than or equal to 55mm and are less than or equal to 85mm, in this way, can cause battery
Bag 15 and the distance between baseplane 141 are big enough in will not cause to interfere to the surface of workpiece.
As shown in figure 4, battery pack 15 further includes several battery core units 152, battery core unit 152 is columnar lithium battery,
The extending direction of battery core unit 152 is also parallel with 102 direction of output axis.Multiple battery core units 152 are along perpendicular to output axis
102 directions are set gradually.
