[0047] In the embodiment, one end of the tightening ropes one 33 and the tightening ropes two 34 penetrates the mounting plate 31, and the end of the tightening ropes one 33 is lower than that of the tightening ropes two 34, so that the tightening ropes one 33 can be connected with the winding disc of the tightening shaft one 35.

[0048] The working principle of the utility model is as follows:

[0049] When one end of the bellows is placed between the inner extension pipe 11 and the outer extension pipe 21, the hand wheel outside the outer extension pipe 21 of the tightening shaft one 35 can be manually rotated to rotate the tightening shaft one 35 and reverse rotate the tightening shaft two 36 through the transmission of the gear two 38 and the gear one 37, so that the tightening shaft one 35 and the tightening shaft two 36 tighten one end of the tightening rope one 33 and the tightening rope two 34, respectively, and since the other end of the tightening rope one 33 and the tightening rope two 34 is fixedly connected below the mounting plate 31, the tightening rope one 33 and the tightening rope two 34 are tightened inward during winding, so that the arc-shaped wave plate 41 also starts to move towards the inner extension pipe 11 through the receiving plug plate 46 outside the periphery of the arc-shaped wave plate 41, thereby quickly connecting the bellows.

[0050] During the winding of the tightening rope one 33 and the tightening rope two 34, since the fixed end of the tightening rope one 33 and the tightening rope two 34 opposite to the mounting plate 31 is opposite, the rotation directions of the tightening shaft one 35 and the tightening shaft two 36 are opposite, and when the tightening rope one 33 and the tightening rope two 34 are wound, the forces exerted by the tightening rope one 33 and the tightening rope two 34 on the plurality of positioning assemblies 4 are uniform, so that the positioning of the bellows is also more uniform, and thus the number of rotations does not need to be recorded during connection, so that the connection is more rapid and convenient, and the force is uniform.

[0051] During the inward extrusion of the plurality of arc-shaped wave plates 41, the extension arc plate 43 at one end of the arc-shaped wave plate 41 will slide above the abutting arc plate 42 at the other end of the arc-shaped wave plate 41, and the abutting arc plate 42 will gradually move towards the other end of the arc-shaped wave plate 41, so that when the plurality of arc-shaped wave plates 41 are inwardly contracted and pressed towards the periphery of the bellows, the pressure gap is avoided, thereby ensuring the airtightness.
