And the inner connecting sleeve 3 and the outer connecting sleeve 4 are both axially provided with first openings 8 in a penetrating way. The inner connecting sleeve 3 and the outer connecting sleeve 4 are made of manganese steel with good elasticity, the loop 5 is made of No. 20 steel, and the surface of the loop is plated with wear-resistant chromium. The lengths of the rotary sleeve 2, the inner connecting sleeve 3, the outer connecting sleeve 4 and the loop 5 are equal. The bearing is arranged on a shaft extending out of the right end of the supporting seat 1 of the movable sleeve wheel.
When the outer connecting sleeve 4 moves rightwards relative to the inner connecting sleeve 3, the outer connecting sleeve 4 and the inner connecting sleeve 3 are tensioned between the loop 5 and the rotary sleeve 2 under the action of the conical surface, and the loop 5, the outer connecting sleeve 4, the inner connecting sleeve 3 and the rotary sleeve 2 are fixedly connected together; when the outer connecting sleeve 4 moves leftwards relative to the inner connecting sleeve 3, a gap is formed between the outer connecting sleeve 4 and the loop 5 under the elastic action, and the loop 5 can be replaced at the moment. The loop 2 is made of steel pipe and plated with chrome on the surface, so that the wear resistance of the loop can be improved, a large amount of steel is saved, and the manufacturing cost is reduced. The loop 5 and the rotary sleeve 2 are detachably connected through the matching between the outer connecting sleeve 4 and the inner connecting sleeve 3, the requirement on the machining size precision of the inner circle of the loop 5 is not high, and the machining cost of the loop 5 is reduced. The loop 5 can be replaced quickly after being worn, so that the maintenance time is reduced, the production efficiency and the equipment operation time are improved, and the yield is increased. Because the manufacturing cost of the loop 5 is low, the loop is used as a wearing part and is directly scrapped after being worn without maintenance, and a large amount of maintenance cost can be saved.
