As shown in
As shown in
The axis bodies 4 and the drums 2 have the specific structures as follows:
As shown in
As shown in
When any one of the drums 2 rotates on the corresponding axis bodies 4, the fixed columns 41 of the axis bodies 4 rotate in any direction in the bearing installation holes 21 through second bearings 6, and meanwhile the axis levers 43 can rotate in the axis holes 25 and the second built-in slots 26 in respective.
It is worth noting that diameters of the fixed columns 41 are less those that of the axis levers 43, and the stability when the drums 2 rotate on the side walls of the axis levers 43 is ensured by increasing the diameters of the axis levers 43.
To reduce the discomfort caused by sharp parts to human bodies during rotation of the drums 2, a transition surface 22 from a side wall of any one of the four drums 2 to the two end faces thereof is an arc surface, and a transition edge 23 from the two end faces of any one drum 2 to the each of the first built-in slots 24 and each of the second built-in slots 26 is an arc edge, to reduce the transition surface 22 from the side wall of each of the drum 2 to the two end faces thereof; and if the transition surface 22 is a sharp shape, a situation of a blocked rotation in fingers and palms is caused during rotation, and meanwhile the design that the transition edge 23 from the two end faces of the drums 2 to each of the first built-in slots 24 and each of the second built-in slots 26 is the arc edge can also prevent a situation of flesh cuts caused on the finger skin by the end faces.
