[0029] Furthermore, the sliding block 42 is penetrated by the card rod 421 and is slidably connected to the card rod 421. The card rod 421 is provided with a through slot 425. The inner wall of the through slot 425 is fixedly connected to one end of a spring 1 422. The other end of the spring 1 422 is fixedly connected to the inner wall of the sliding block 42. The through slot 425 is penetrated by the oblique rod 423 and is slidably connected to the oblique rod 423. The outer wall of the oblique rod 423 is fixedly connected to a sliding plate 424. The end of the sliding plate 424 away from the oblique rod 423 is fixedly connected to a motion rod 426. The outer wall of the motion rod 426 is fixedly connected to one end of a spring 2 427. The other end of the spring 2 427 is fixedly connected to the inner wall of the sliding block 42.

[0030] When the valve body 1 is to be cut off, the sleeve 5 is removed, and the runner is then installed on the screw 45, and then turned to the screw 45. When the screw 45 rotates, the sliding block 42 moves downward under the action of the screw 45. When the sliding block 42 moves to the bottom, the fixed rod 11 contacts the moving rod 426. At the same time, the fixed rod 11 squeezes the moving rod 426, causing the moving rod 426 to move upward. When the moving rod 426 moves, the sliding plate 424 fixedly connected to the moving rod 426 drives the oblique rod 423 to move upward. During this process, the oblique rod 423 slides in the through groove 425. At the same time, the oblique rod 423 squeezes the clamping rod 421, causing the clamping rod 421 to completely enter the sliding block 42. When the clamping rod 421 enters When the piston rod 41 is inside the sliding block 42, the screw 45 continues to be rotated. During this process, the piston rod 41 slides toward the inner wall of the sliding block 42, and the spring three 44 undergoes elastic deformation. When the piston rod 41 moves, the air pressure inside the sliding block 42 increases. At this time, the rubber pad 43 will expand under the action of the air pressure, so that the rubber pad 43 fits more closely with the inner wall of the valve body 1, thereby improving the sealing effect of the valve body 1. When the screw 45 is rotated in the opposite direction, the screw 45 moves upward. When the screw 45 moves upward, the piston rod 41 will move upward under the action of the spring three 44. At this time, the rubber pad 43 will return to its original shape under the action of pressure. This design can effectively reduce the friction between the rubber pad 43 and the inner wall of the valve body 1 through the deformation of the rubber pad 43, thereby preventing the rubber pad 43 from wear.
