Preferably, the sliding handle is provided with a connecting plate, the connecting plate is a U-shaped plate, the U-shaped plate is provided with a hinge hole and a limiting hole, the hinge hole and the limiting hole are respectively connected with a pin shaft, the pin shaft transversely penetrates through the waist circular hole in the circular tube and moves back and forth along the waist circular hole, and the pin shaft in the hinge hole penetrates through the two claws of the hinge claw.

Preferably, the two claws of the claw are connected in the U-shaped groove of the U-shaped plate through pin shafts.

Preferably, the sliding handle is provided with a pull ring.

Preferably, the tail end of the pin shaft is provided with a jack, and a cotter pin is inserted into the jack.

The edges of all parts need to be chamfered, and the corners need to be smoothly transited and blackened.

The use principle of the cover extractor for the spiral finned tubes, the membrane walls and the serpentine tubes is as follows: the two claws of the claw are driven to do reciprocating motion along the waist circular hole by the sliding handle, and the two claws of the claw are limited by the limiting plate at the tail end and the limiting plate at the front end of the moving groove in the reciprocating motion process, so that the two claws of the claw can finish grasping and loosening actions respectively.

The utility model has simple and reasonable structure, can effectively and quickly take off the plastic protective cover at the end part of the pipe, and does not damage the plastic protective cover through the arrangement of the claw arc plate, so that the plastic protective cover can be repeatedly used, thereby reducing the cost; the clamping jaw can be adjusted, stretched and retracted to clamp plastic protective covers of pipes with different specifications and sizes, and the application range is wide.
