Detailed Description

In the drawings 1-3, the utility model is composed of a spanner bar 1, a reinforcing rib 2, an arc body 3 and a pin shaft 4, wherein the spanner bar 1 is welded with the arc body 3, and the reinforcing rib 2 connects, reinforces and fixes the spanner bar 1 and the arc body 3. Supporting convex surfaces 5 are arranged at two ends of the inner wall of the arc-shaped body 3. The joint of the pin shaft 4 and the inner surface of the positioning panel 6 is provided with an annular groove 7. The end part of the big end of the pin shaft 4 is chamfered to form an inner groove wall, and the tail end of the outer groove wall and the tail end of the inner groove wall are butted to form a concave conical groove 7. Only the supporting convex surface 5 contacts with the surface 82 of the piece to be dismounted, the rest surfaces do not contact with the surface 82 of the piece to be dismounted, the inner surface of the positioning panel 6 contacts with the end surface 83 of the piece to be dismounted for positioning, and the piece to be dismounted is rotated through the pin shaft 4 which is arranged on the inner surface of the positioning panel 6 and inserted into the dismounting hole, so that the aim of dismounting and mounting is achieved.
