At the same time, six groups of connecting rods are evenly provided on the outer side of the circumference of the mounting ring.
[0009] Preferably, positioning seats are fixedly installed on the ends of the six groups of connecting rods, and the sizes of the positioning seats are adapted to the sizes of the positioning grooves. At the same time, positioning seats are installed inside the six groups of positioning grooves.
