[0004] Although the prior art can prevent the skin inside the protective cover from being easily corroded, the compensator disassembly step is relatively cumbersome, and the service life of the skin is relatively short compared to the external connecting pipe. When the skin reaches the service life, the compensator cannot be disassembled, and the skin is replaced alone, which has certain limitations.

[0005] Therefore, we propose a detachable nonmetal compensator to solve the above problems. UTILITY MODEL CONTENTS

[0010] Further, the clamping mechanism comprises an external thread pipe, the external thread pipe is fixedly connected to the end side of the pipe body joint, and the outside of the external thread pipe is screw connected with an internal thread ring, the side of the pipe body joint is fixedly connected with a fixed rod, and the outside of the fixed rod is nested with a clamping block.

[0011] Further, the inside of the pipe body joint is provided with a butt joint groove, the end side of the skin is fixedly connected with a butt joint block, and the number of the butt joint blocks is equal to the number of the butt joint grooves, and the butt joint blocks can be connected to the inside of the butt joint grooves.

[0012] Further, the end side of the clamping block and the pipe body joint are fixedly connected with a torsion spring, the torsion spring is arranged on the outside of the fixed rod, and the lower end of the clamping block can be clamped with the end side of the skin.

[0013] Further, the clamping block and the fixed rod constitute a rotating structure through the internal thread ring, and the clamping block and the pipe body joint constitute an elastic structure through the torsion spring.

[0017] 2. When the positions of the two sets of pipe body joints and the skin are preliminarily adjusted, the inner threaded ring can be rotated, so that the inner threaded ring moves downward along the outer threaded pipe. During the downward movement of the inner threaded ring, the outer end of the clamping block is in contact with the inner side of the outer end, so that the clamping block rotates along the fixed rod. At this time, the inner end of the clamping block can clamp the end side of the skin, and the skin is further limited.
