Face and a bottom surface are constituted, and multi-turn groove is wherein suppressed on side, and the center of bottom surface is provided with circular through hole, described
Middle ring is cylindrical iron hoop, and middle ring bottom is provided with ladder mouth, and the ladder mouth of middle ring is embedded in the bottom surface through-hole of outer wheel body, middle ring
Inside is opened there are three semi-circular recesses, and the outer wheel cap middle part is provided with through-hole, and outer wheel cap and outer wheel body pass through fixed spiral shell respectively
Bolt is fixed on the two sides of middle ring, and the outer ledge of outer wheel cap covers the opening of outer wheel body just, and the inner ring is C font iron
Ring, inner ring are embedded in middle ring, and are opened on the outside of inner ring there are three semi-circular recesses corresponding with middle ring groove, inner ring groove with
Space between middle ring groove is provided with connection bolt.
Further, the keyway of fixed rotating shaft is provided on the inside of the inner ring.
Further, the radius of the connection bolt is greater than the groove radius of middle ring and inner ring.
Compared with prior art, the utility model has the beneficial effects that
1. structure is simple, construction is reasonable, processing cost is low；
2. easy for assemble or unload, operation is easy；
3. fixation, intensity meet requirement.
