[Detailed ways]

As shown in Figures 1 to 3, a three-sided brush electric toothbrush includes a brush handle 1, an inner chamber (not shown) is provided on the brush handle 1, and a driving mechanism is provided in the inner chamber, which includes a driving motor 6 1. The bevel gear 7 connected with the driving motor, the bevel gear 7 meshes with the gear 8 with gear teeth on one side, the eccentric shaft 81 on the gear 8 is connected with a transmission rod 9, and the driving motor 6 is connected with a power supply; one end of the brush handle 1 A base 101 is provided, and a groove 1010 is provided on the base 101. A first brush head 2 that can be driven by a driving mechanism to slide back and forth is arranged in the groove 1010. The first brush head 2 is provided with bristles 3; the left and right sides of the base 101 There are left lug 1011 and right lug 1012 respectively extending in the same direction, and mounting holes 1014 are provided on the opposite sides of left lug 1011 and right lug 1012, and a second brush head is installed in the two mounting holes 1014 through shaft 402 4. Both the second brush heads 4 are provided with bristles 3, and there is a cavity 1013 connected between the left lug 1011, the right lug 1012 and the base 101, and a connecting piece 5 is placed in the cavity, and The first brush head 2 is connected as a whole, and the connecting piece 5 is connected with the transmission rod 9 .

Pulling forks 501 are respectively provided at both ends of the connecting piece 5 , and protruding locking blocks 401 are provided on the two second brush heads 4 , and the locking blocks 401 are clamped in the pulling forks 501 . In order to make the rotation angle of the second brush head 4 large enough, in the present invention, it is preferred that the area of the fork 501 surrounding the block 401 is surrounded by a "C"-shaped arc surface.
