It will of course be understood that, the electric tool 100 of the hand-held can also be other instruments, such as angle mill, trimmer
Deng.As long as in fact, employing the essentiality content of this case scheme disclosed below, belonging to the model that the utility model is protected
Enclose.
As shown in Figure 1 to Figure 3, electric tool 100 includes：Handle casing 11, motor 12, output shaft 13, chuck 14, support
15th, the first fan 16 and the second fan 17.
Wherein, handle casing 11 as electric tool 100 shell, for accommodating motor 12, output shaft 13, the first fan
16 and second fan 17 etc..Handle casing 11 is also formed with the handle portion 111 for being gripped for user.Specifically, outside handle
Shell 11 substantially extends along a straight line, and it includes：First housing 112 and the second housing 113.First housing 112 is used for more than formation
Described handle portion 111, one end of the first housing 112 is used to install the power line of external AC, the company of other end formation first
Socket part 112a.First housing 112 is also about being formed with a first chamber 112b, and motor 12 is arranged in first chamber 112b.
Second housing 113 is formed with second connecting portion 113a, the other end close to one end of the first housing 112 and opened wide to cause output shaft 13
Part is extend out to outside handle casing 11.Second housing 113 is also about forming second chamber 113b, and support 15 is arranged on the second chamber
In the 113b of room, output shaft 13 is also mainly disposed in second chamber 113b.The periphery of second housing 113 can also be as supplying
The assist handle that user grips, enables a user to the more stable operation electric tool 100.First housing 112 passes through
Connections and second housing 113 of the first connecting portion 112a with second connecting portion 113a, which are constituted, to be fixedly connected, and both specifically may be used
Connection is constituted with the screw that first connecting portion 112a and second connecting portion 113a are sequentially passed through by one.
Motor 12 is arranged in handle casing 11, furthermore, is arranged on the first chamber that the first housing 112 is formed
In 112b.Motor 12 includes：Stator 121, rotor 122 and armature spindle 123, wherein, stator 121 and rotor 122 are arranged at
In the first chamber 112b that one housing 112 is formed, armature spindle 123 is that axle is spindle rotationally arranged in handle with first axle 101
In shell 11.Armature spindle 123 is mainly disposed in first chamber 112b, certainly, and armature spindle 123 can also partly extend out to first
Outside chamber 112b.It should be noted that motor 12 is arranged in first chamber 112b and is not restricted to armature spindle 123 and also sets completely
Put in first chamber 112b, for example in the present embodiment, stator 121 and rotor 122 are arranged in first chamber 112b, only
The only part of armature spindle 123 is extend out to outside first chamber 112b, at this moment still it is considered that motor 12 is provided in first chamber
In 112b.For the straight grinder, handle casing 11 overall extends approximately along the direction of first axle 101, because
This electric tool 100 is preferably a kind of linear instrument.
Output shaft 13 can be driven by motor 12 to be rotated with first axle 101 for axle, and output shaft 13 is also along the side of first axle 101
To extension, the part of output shaft 13 is arranged on the second housing 113 and surrounded in the second chamber 113b formed.Output shaft 13 is close to electricity
One end of machine 12 constitutes drive connection, the other end with armature spindle 123 and extend out to outside second chamber 113b to export power.
Chuck 14 be used for installment work annex, such as being installed blade wheel, emery wheel, polishing wheel, thus realize grinding,
The function of polishing etc..Specifically, chuck 14 is arranged on outside handle casing 11, and positioned at handle casing 11 away from circumscripted power line
One end.Chuck 14 is arranged on the one end of output shaft 13 away from armature spindle 123, and synchronous axial system is constituted with output shaft 13, so as to
Working accessory is driven to rotate to realize various functions.
Support 15 is arranged in the second chamber 113b that the second housing 113 is formed, and support 15 is used to rotatably support
Output shaft 13, so that the energy opposite brackets 15 of output shaft 13 and handle casing 11 are rotated.Specifically, support 15 is approximately along
The direction of one axis 101 is arranged in second chamber 113b, and output shaft 13 passes through support 15.Two axles are also accommodated in support 15
18 are held, the two bearings 18 are separately mounted on the position at the close two ends of output shaft 13.Therefore, support 15 here also may be used
To be the equal of the bearing block for spring bearing 18
First fan 16 is arranged in first chamber 112b, and the first fan 16 is also arranged on armature spindle 123.So,
After electric tool 100 starts, the first fan 16 can be driven and rotate by motor 12, so as to in first chamber 112b
The structure such as motor 12 radiated.
Second fan 17 is arranged in second chamber 113b, and the second fan 17 is also arranged on output shaft 13 and and output shaft
13 constitute synchronous axial system.After electric tool 100 starts, armature spindle 123 driving output shaft 13 rotate to export power, at this moment with
The second fan 17 that output shaft 13 constitutes synchronous axial system is also rotated in the lump with output shaft 13, so as to be produced in handle casing 11
It is raw to flow through the radiating airflow of support 15, and then the output shaft 13 in second chamber 113b, support 15 etc. are radiated.
Furthermore, the second housing 113 is opened wide in the end away from the first housing 112 towards chuck 14, the second fan
17 are arranged on the position being located in the second housing 113 of output shaft 13, and the second fan 17 is arranged on the direction of the second housing 113
The unlimited position of chuck 14.So, when the second fan 17 is rotated in the lump with output shaft 13, it can be dried towards chuck 14,
So as to which the dust of chuck 14 and the surface of the workpiece of the annex of chuck 14 be dispelled.
In order to effectively be radiated to output shaft 13, support 15 and bearing 18, during support 15 is also with first axle 101
Thimble is around output shaft 13, and the second housing 113 is also centered on first axle 101 around support 15, so, in the second housing 113
Inwall and support 15 outer wall between yet forms both at least partially along the gas channel extended parallel to the direction of first axle 101
19.Second fan 17 is arranged on gas channel 19 close to the side of chuck 14.In addition, be also formed with the second housing 113 with
The air flow inlet 113c that gas channel 19 is connected, air flow inlet 113c are also located at the one end of gas channel 19 away from chuck 14.From
And, when the second fan 17 is rotated with output shaft 13, radiating airflow can be oriented to and enter to gas channel from air flow inlet 113c
19, and support 15, output shaft 13 and bearing 18 etc. are radiated when flowing through support 15, then again from the second housing 113
The one end opened wide towards chuck 14 flow out and blow to chuck 14 and chuck 14 near, and then the setting of the second fan 17 can also
Improve drifting dust effect.
In addition, second chamber 113b is also closed with respect to first chamber 112b, such energy of first fan, 16 and second fan 17
Part in enough independent first chamber 112b and second chamber 113b to respective place radiates, so as to improve radiating effect
Really.Therefore, the one end of the first housing 112 away from the second housing 113 is also formed with the first air flow inlet 112c, first connecting portion
It is formed with 112a and second connecting portion 113a towards extraneous unlimited air stream outlet 112d, air stream outlet 112d and first chamber
112b is connected, so that, the first fan 16 can effectively be radiated when rotating to motor 12.
General principle of the present utility model, principal character and advantage has been shown and described above.The technical staff of the industry
It should be appreciated that above-described embodiment does not limit the utility model in any form, it is all by the way of equivalent substitution or equivalent transformation
The technical scheme obtained, all falls within protection domain of the present utility model.
