Abstract
The present invention discloses an electric tool which includes a housing, a motor, an eccentric member and a synchronization member. The motor is disposed in the housing, the output shaft of the motor is engaged with a driven gear driven by a drive gear, the driven gear is fixed together with or integrated with the eccentric member, the drive gear and the eccentric member are rotatably coupled with the shaft, the shaft is fixed on the housing, the periphery of the eccentric member is slide and coupled with the displacement hole of the synchronization member, the guide arm of the synchronization member is reciprocating sliding and coupled with the guide support fixed on the housing, the synchronization member has a connection part protruding to the outside of the housing. The invention is simple in structure and assembly and low in cost.
Description
Technical field
The present invention relates to a kind of power hand tool.
Background technique
Existing electric tool, the disclosed power hand tool of Chinese patent literature CN1284419 for example, the live axle that is arranged on the motor in the housing bevel gear that is in transmission connection, driven shaft of bevel gear drive by the bearing supporting, driven shaft rotates and drives eccentric part and synchronous piece to-and-fro motion, and bevel gear drive is arranged in the separable housing.Have the following disadvantages: complex structure, the assembling trouble, efficient is low, the cost height,
Summary of the invention
The object of the present invention is to provide a kind of simple in structurely, assemble simple electric tool.
In order to achieve the above object, technological scheme of the present invention is: a kind of electric tool, comprise housing, motor, eccentric part and synchronous piece, motor is arranged in the housing, the output shaft of motor is by actuation gear and driven gear engagement driving, driven gear is fixedlyed connected with eccentric part or is made one, driven gear and eccentric part and axle are rotatably assorted, axle is fixed on the housing, the displacement aperture of eccentric part periphery and synchronous piece is slided and is matched, the leading arm of synchronous piece reciprocatingly slides with guided bearing on being fixed on housing and cooperates, and synchronous piece has and stretches out the outer joint of housing, and the joint that has on the housing for synchronous piece stretches out and reciprocating groove.
After adopting said structure, because driven gear is fixedlyed connected with eccentric part or made one, driven gear and eccentric part and axle are rotatably assorted, and axle is fixed on the casing, and axle does not rotate, and has cancelled the structure of bearings rotating shaft of the prior art, and is therefore, simple in structure; Because driven gear is fixedlyed connected with eccentric part or made one, and the displacement aperture of eccentric part periphery and synchronous piece is slided and matched, so compact structure, assembling is simple again.And when assembling, driven gear can be put into casing earlier, refills motor then, need not the casing of together packing into again after the two assembling earlier, and is simple to operate, the efficient height, and cost is low.

Embodiment
The embodiment who provides below in conjunction with accompanying drawing does explanation in further detail to the present invention.
As Fig. 1,2,3, shown in 4, electric tool of the present invention, comprise housing 1, motor 2, eccentric part 6 and synchronous piece 8, motor 2 is arranged in the housing 1, the output shaft of motor 2 is by actuation gear 3 and driven gear 4 engagement driving, driven gear 4 is fixedlyed connected with eccentric part 6 or is made one, driven gear 4 and eccentric part 6 are rotatably assorted with axle 5, axle 5 is fixed on the casing 1, the displacement aperture 8-3 of eccentric part 6 peripheries and synchronous piece 8 slides and matches, the leading arm 8-1 of synchronous piece 8 reciprocatingly slides with guided bearing 7 on being fixed on casing 1 and cooperates, and synchronous piece 8 has and stretches out the outer joint 8-2 of housing 1.
Shown in Fig. 1,4,5, guided bearing 7 is gripped by the grip slipper 1-4 on the left and right housing that is located at housing 1.
As shown in Figure 1, 2, 3, actuation gear 3 is spur gears, and driven gear 4 is ring gears.Certainly, actuation gear 3 and driven gear 4 all can be umbrella gear; Actuation gear 3 and driven gear 4 can all be spur gears also, or helical gear etc.
As shown in Figure 2, for the centre distance of regulating driven gear 4 and actuation gear 3 to reach the optimal engagement state, be provided with pad 9 between the both ends of the surface of driven gear 4 and the housing 1.
As shown in Figure 4, the joint 8-2 that has on the housing 1 for synchronous piece 8 stretches out and reciprocating groove 1-3.
Shown in Fig. 2,6, for motor 2 is installed easily, the shell two ends of motor 2 have boss 2-1, all have corresponding supporting base 1-1 on the left and right housing of housing 1, all have the groove 1-1-1 that snaps in for boss 2-1 on each supporting base 1-1.
As shown in Figure 1, in the housing 1 battery compartment 1-2 is set.
As shown in Figure 1, switch 11 is housed also on the housing 1, switch 11 is electrically connected with battery compartment 1-2 and motor 2.
As shown in Figure 1, when the present invention works, press switch 11, make the battery in the battery compartment 1-2 give motor 2 power supplies, the output shaft of motor 2 drives driven gear 4 by actuation gear 3 and eccentric part 6 rotates on axle 5.The displacement aperture 8-3 of the periphery of eccentric part 6 and synchronous piece 8 is slidingly matched, and makes synchronous piece 8 move left and right.At this moment, the leading arm 8-1 of synchronous piece 8 reciprocatingly slides in guided bearing 7.The joint 8-2 of synchronous piece 8 is connected with cutter 10, and cutter 10 moves back and forth with synchronous piece about 8.Cutter 10 can be blade or saw blade or file etc.
