Inside the fixed cover 1 and at the upper and lower positions, storage grooves 103 are formed. Inside the fixed cover 1 and near the upper position, a rod groove 102 is formed. The storage grooves 103 communicate with the annular grooves 104. The storage grooves 103 can store the first arc-shaped movable plate 6 and the second arc-shaped movable plate 5 when not in use. On the inner surfaces of the first retaining ring 2 and the second retaining ring 3, a rotating ring 201 is formed. On the opposite side surfaces of the first retaining ring 2 and the second retaining ring 3 and at the upper position, an embedding groove 202 is formed. The transmission member 8 includes a rotating rod 801, a gear 802, and a bevel gear 803. On the surface of the rotating rod 801 and near both ends, the gears 802 are fixedly sleeved. On one end surface of the rotating rod 801, a bevel gear 803 is fixedly installed. The cooperation between the bevel gear 803 and the bevel gear groove 704 can drive the transmission member 8 to rotate when the rotating member 7 rotates. The rotating member 7 includes a worm gear 701 and a connecting ring 702. On the front surface of the worm gear 701, a connecting ring 702 is fixedly installed. On the outer surface of the connecting ring 702, a rotating groove 703 is formed. On the inner surface of the worm gear 701, a bevel gear groove 704 adapted to the bevel gear 803 is formed.
