[0033] In this embodiment, multiple groups of fixed blocks 603, rotating rods 604, rotating tubes 605, and clamping plates 606 are arranged in a circular pattern and their central axes are on the same horizontal line, so that the connecting pipe can be clamped at multiple locations, thereby enabling the valve 2 to be tightly fixed to the connecting pipe.

[0045] When the valve 2 is initially clamped at the connecting pipe, by holding the handle 609 at the top of the rotating rod 604, it can synchronously drive the rotating rod 604 to rotate clockwise. Since the outer wall of the rotating rod 604 is provided with a threaded groove 610, and the inner wall of the rotating tube 605 is provided with a threaded protrusion 611 with the same number of threads and size as the threaded groove 610, at the same time, the outer wall of the rotating tube 605 is welded with a clamping block 612, and one end of the clamping block 612 is provided with a plug-in groove, and a guide rod 613, one end of which is fixedly connected to the inner wall of the fixed tube 602, is limitedly inserted in the inner cavity of the plug-in groove, and the limit clamping groove 607 provided in the inner cavity of the fixed block 603 and the limit clamping block 612 fixedly connected to the inner wall and the outer wall of the rotating rod 604 are provided. 08 The two are movably connected, so that it will not affect the rotation of the rotating rod 604 on the fixed block 603, and at the same time the rotating rod 604 can be limited and fixed on the fixed block 603. When the rotating rod 604 rotates clockwise, the rotating tube 605 can move toward the connecting tube on the outer wall of the rotating rod 604, so that the connecting tube can be clamped and fixed by the overall arc-shaped clamping plate 606, and a second rubber sheet 614 is bonded to one side wall of the clamping plate 606, so that the friction between the inner wall of the clamping plate 606 and the outer wall of the connecting tube can be increased, so as to prevent the clamping plate 606 from sliding on the connecting tube, so as to achieve the effect of making it convenient for users to fix the leak-proof valve on the connecting pipe.
