The handle 20 further comprises at least one motor 22, at least one transmission member 23, at least one linkage member 24 and a drive shaft 25. The motor 22 is installed inside the transmission member 23, and the link member 24 is sleeved outside the transmission member 23. The linkage 24 and the transmission member 23 are sleeved together to reduce the overall length and reduce the distance over which kinetic energy is transmitted. One end of the drive shaft 25 is fixed to one end of the link 24. The driving shaft 25 and the transmission member 23 are respectively fixed by two ends of the linkage member 24. The transmission member 23 and the linkage member 24 are sequentially and fixedly installed to form a transmission mechanism, and the transmission mechanism transmits the kinetic energy output by the motor 22 to the driving shaft 25. The kinetic energy is output from the motor 22 to the transmission member 23, and is further transmitted to the link member 24, and finally drives the drive shaft 25 fixed to the link member 24 to vibrate.
The transmission member 23 includes a sleeve portion 231 and a mounting portion 232, and the mounting portion 232 is formed at one end of the sleeve portion 231. The sleeve portion 231 is hollow and sleeve-shaped. The motor 22 is mounted in the sleeve portion 231, and is fixed to the sleeve portion 231. The link 24 is sleeved outside the sleeve portion 231, and the transmission member 23 and the link 24 are connected to form the transmission mechanism. The mounting portion 232 is fixedly mounted to the housing 21 so that the transmission mechanism is mounted to the housing 21. At least a portion of the mounting portion 232 may be deformed such that at least a portion of the mounting portion 232 may be displaced. The mounting portion 232 is deformed and displaced, and the sleeve portion 231 is movable relative to the housing 21. The transmission member 23 is movably mounted to the housing 21 to enable transmission.
The mounting portion 232 includes at least one elastic portion 2321 and at least one fixing portion 2322, and at least one fixing portion 2322 is formed on at least one side of the elastic portion 2321.

The mounting portion 232 further includes a connecting portion 2323, and the connecting portion 2323 connects the elastic portion 2321 and the sleeve portion 231. The connection portion 2323 extends from one end of the sleeve portion 231, and the elastic portion 2321 extends from the connection portion 2323 to at least one side. The elastic portion 2321 has at least one bending portion, so that the elastic portion 2321 can be stretched and extended for a certain distance. When the elastic portion 2321 is pressed by a force, the elastic portion can also contract and deform. The fixing portion 2322 is formed at an end of at least one side of the elastic portion 2321. Since the elastic part 2321 can be stretched or contracted, the elastic part 2321 can move in at least one direction when being applied with a force. The sleeve 231 is connected to the elastic portion 2321 through the connection portion 2323, and when the sleeve 231 is driven by the motor 22, the elastic portion 2321 is deformed by a force, and the sleeve 231 moves in at least one direction.
When the sleeve portion 231 is driven by the motor 22, the force applied to the sleeve portion 231 from the motor 22 is transmitted to the elastic portion 2321, and the elastic portion 2321 is deformed by the force, thereby pulling the sleeve portion 231 to move in at least one direction.
In an example of the present invention, the elastic part 2321 is bent and extended from the connection part 2323 to both sides, and the fixing parts 2322 are respectively formed at both ends of the elastic part 2321 to be fixed to the housing 21. The elastic portion 2321 is deformed and moved between the fixing portions 2322.
The elastic portion 2321 has a W-shape, and intersects with the extending direction of the connection portion 2323.

Fig. 5 to 7 show the movement of a drive mechanism of the electric toothbrush, which includes the motor 22, the transmission member 23, the link member 24, and the drive shaft 25. When the motor 22 is not started, the elastic portion 2322 of the transmission member 23 is in an initial state. The transmission 23, the linkage 24 and the drive shaft 25 are stationary and the levers are balanced. When the motor 22 is started, the transmission member 23 receives a force from the motor 22, the elastic portion 2322 is deformed, and the sleeve portion 231 moves in at least one direction, so as to drive the linkage member 24 to move in at least one direction, and further drive the driving shaft to move in at least one direction. When the motor 22 moves in another direction, the elastic portion 2322 is reversely deformed, and the sleeve portion 231 moves in at least another direction, so as to drive the link 24 to move in at least another direction, and further drive the driving shaft 25 to move in at least another direction. The drive mechanism moves in at least two directions.
