[0028] According to this specific embodiment, the clamping assembly is disposed on the corresponding positioning flange 105 . When in use, the clamping assembly can lock the valve stem 209 of the valve body 104 .

[0029] The fixing plate 203 is fixedly connected to the corresponding positioning flange 105, one end of the two support rods 205 is fixedly connected to the fixing plate 203, the other end of the two support rods 205 is penetrated by a sliding member, the two ends of the spring 204 are fixedly connected to the fixing plate 203 and the sliding member respectively, the movable gear 202 is fixedly linked to the sliding member, the fixing gear 201 is fixedly connected to the valve stem 209 of the valve body 104, the fixing gear 201 is meshed with the movable gear 202, and when the valve stem 209 of the valve body 104 needs to be rotated, the fixing gear 201 is pressed down. The movable gear 202 drives the sliding member to move, and the sliding member drives the spring 204 to contract, so that the driven gear moves away from the fixed gear 201, and then the valve stem 209 of the valve body 104 can be rotated. When the rotation is completed, the driven gear is released, and the spring 204 resets and stretches to drive the sliding member to move, and the sliding member drives the driven member to move up and mesh with the fixed gear 201, so that the fixed gear 201 cannot rotate and the valve stem 209 of the valve body 104 cannot rotate, thereby improving the stability of the valve body 104.

When it is necessary to rotate the valve stem 209 of the valve body 104, the movable gear 202 is pressed down, and the movable gear 202 drives the sliding member to move. The sliding member drives the spring 204 to contract, so that the driven gear moves away from the fixed gear 201. Then, the valve stem 209 of the valve body 104 can be rotated. When the rotation is completed, the driven gear is released. At this time, the spring 204 resets and stretches to drive the sliding member to move. The sliding member drives the driven member to move up and mesh with the fixed gear 201, so that the fixed gear 201 cannot be rotated and the valve stem 209 of the valve body 104 cannot be rotated, thereby improving the stability of the valve body 104.
