Preferably, the side of the brake block adjacent to the rotating shaft is semi-arc shaped.
Preferably, the brake blocks correspond to the rotation shaft.
Preferably, the fan blades are three in number.
Preferably, a rubber strip is fixedly connected to one side of the brake block close to the rotating shaft.
Preferably, a sliding block is fixedly connected to the brake block, and a sliding groove corresponding to the sliding block is formed in the inner wall of the device shell.
Has the advantages that:
1. the first braking device and the second braking device brake simultaneously, so that the effects of slowing and braking the rotating shaft are achieved, and the speed of the rotating shaft can be better controlled.
2. The utility model discloses an electric putter promotes brake pads extrusion axis of rotation and produces great frictional force, reduces the rotational speed of axis of rotation to reach the effect that the axis of rotation slows down, brakies.
