A finger strengthening rotation disk comprises a left palm support omnidirectional column-shaped member (1), a left finger plate (3), a left base plate (4), a right base plate (5), a right finger plate (6) and a right palm support omnidirectional column-shaped member (8) sequentially disposed in an axial direction. A plurality of finger holes (301, 601) for finger insertion are provided on the plate faces of the left and right finger plates (3, 6) having the left and right palm support omnidirectional column-shaped members (1, 8) thereon. A rotation shaft (9) is provided between the left base plate (4) and the right base plate (5), and a magnetic metal flange (901) is radially provided at a middle portion of the rotation shaft (9), and the rotation shaft (9) is sleeved with a pair of magnetic rings (11, 12) respectively located at two sides of the magnetic metal flange (901). A fastening cover (10) covers the magnetic rings (11, 12) and the magnetic metal flange (901). One end of the rotation shaft (9) passes through the fastening cover (10), and then is fixedly connected to the left base plate (4). The fastening cover (10) is fixedly connected to the right base plate (5). The magnetic rings (11, 12) are respectively fastened in the fastening cover (10) facing each other. The finger strengthening rotation disk can enhance motor skills and dexterity of fingers, thereby indirectly improving instrument playing capability of the fingers. |
