In this embodiment, a through groove 102 is formed on the inner walls of the two half rings 1 along the respective arc direction, and the through groove 102 is formed through the half rings 1. The two through grooves 102 are opposite, the outer ends of the two half rings 1 are respectively provided with a through hole 103 in the axial direction, and the through hole 103 penetrates through the two side walls of the through grooves 102. A rotating shaft 2 is movably inserted in the two through holes 103 respectively. For convenience of operation, the outer end of the rotating shaft 2 is provided with a holding part, for example, the holding part may be a knob structure fixedly arranged at the outer end of the rotating shaft 2, and the structure is convenient for manually holding the knob to drive the rotating shaft to rotate; the holding part can also be a cylindrical cap body arranged at the outer end of the rotating shaft 2, and the end face of the cap body is provided with an inner hexagonal blind hole structure through which a hexagonal wrench can be used for driving the rotating shaft to rotate. In the design, a locking mechanism is arranged between the rotating shaft 2 and the semi-ring 1, and the position of the rotating shaft is fixed in time through the locking mechanism. The elastic sealing band 4 is preferably a rubber band with a thickness of 1-3mm, and is located in a space enclosed by the two half rings 1, the width of the elastic sealing band 4 is smaller than the width of the through groove 102, so that after the elastic sealing band 4 moves outwards along with the rotating shaft 2 in the axis direction of the half rings for a certain distance, the elastic sealing band 4 can still keep a flat state without wrinkles, both ends of the elastic sealing band 4 are respectively fixed on the rotating shaft 2, for example, the elastic sealing band 4 can be fixed on the rotating shaft 2 by screws, or the end part of the elastic sealing band 4 and the rotating shaft 2 can be adhesively fixed by using an adhesive, when an adhesive fixing mode is adopted, in order to improve the adhesive firmness, 1/2 that the circumferential length of the rotating shaft adhesive area is not smaller than the circumferential length of the rotating shaft needs to be ensured, that is, the central angle of the rotating shaft adhesive area is not smaller than 180 degrees.
