Through the arrangement, the protective sleeve can protect the outer annular surface and the two end surfaces of the annular body builder, so that the use safety and the service life of the annular body builder are further improved.

Further setting the following steps: the outside cladding of restrictive coating has the oversheath layer, and this oversheath layer extends to the handle by caulking groove department or the edge department of protective sheath of restrictive coating.

Through the arrangement, the outer sheath layer coats the inner ring surface and the two end surfaces of the handle and the sheath layer to play a role in secondary encapsulation, the gripping effect is improved, and the metal impurities entering the sheath layer when the sheath layer encapsulates the framework are prevented from damaging a user.

Further setting the following steps: the sheath layer is connected with the outer sheath layer in an integrated manner.

Further setting the following steps: and anti-skid grains are arranged at the position of the outer sheath layer corresponding to the handle.

Compared with the prior art, the annular body builder has the advantages of simple structure and convenience in manufacturing, improves the production efficiency of the annular body builder, thereby improving the economic benefit, and simultaneously improving the tight and reliable combination of all the parts and the good use safety.
