A movable block 506 is installed in the guide groove 503, and a number of No. 1 fixed rods 507 are installed in the movable block 506. A number of No. 2 fixed rods 508 are installed in the guide groove 503 and at one end close to the motor 501. The No. 2 fixed rods 508 correspond to the No. 1 fixed rod 507 one by one and are parallel to each other.
