The continuously sliding movable plate 201 will drive the rollers 203 on both sides to move in the two movable grooves 202. At the same time, the rollers 203 will contact with the movable grooves 202 and roll during the movement, making the movable plate 201 move more smoothly. The continuously moving movable plate 201 will drive a semicircular track 101 at the corresponding position to move. When the movable plate 201 is completely moved to the other side of the guide groove 200, the two ends of the semicircular track 101 will correspond to the other two tracks 102.
