Wherein, described left shell is the integrative-structure of compression molding, and right casing is the integrative-structure of compression molding.

Wherein, be equipped with tooth bar on first groove of described left shell, second groove, first raised line, second raised line, be equipped with tooth bar on described right casing the 3rd groove, the 4th groove, the 3rd raised line, the 4th raised line, be equipped with fixed orifice in left cover top portion and right casing bottom.

Advantage of the present utility model is:

1. the utility model has solved by frock, and complicated procedures of forming such as tool are finished the problem of assembling, and has realized easy for installation, quick, and quick detachable.

2. the utility model can be saved the labour, reduces work hours, and enhances productivity, and the utility model does not need welding, has strengthened reliability and tensile strength, Stability Analysis of Structures.

3, the utility model is simple in structure, only is made up of porcelain bushing, left shell, three parts of right casing.
