When the axis of the driving handle is coaxial with the axis of the guide rod, the sealing sleeve is in a natural state, when the driving handle rotates by 90 degrees around the rotating pin, the side positioning plane is in contact support with the rear end face of the guide sleeve, the guide rod is pulled backwards for a section of displacement, the sealing sleeve is extruded, and the outer surface of the sealing sleeve expands to tightly seal the water nozzle to realize sealing.

Preferably, a handle is fixed on the side surface of the guide sleeve. When the handle is used, one hand holds the handle, the other hand holds the driving handle to rotate the driving handle by 90 degrees, and the handle is more convenient to use.

Preferably, the front end of the guide sleeve extends forwards to form a connecting convex ring. The seal cover is located between stop collar and the connection bulge loop, and the connection bulge loop also can insert in the water injection well choke to ensure the effective sealing of seal cover.

Preferably, the outer side of the sealing sleeve is provided with a plurality of sealing convex rings. The multiple sealing convex rings form multiple sealing, and the sealing effect is better.

Therefore, the invention has the advantages of convenient use, good sealing performance and effective improvement of the detection efficiency of the water channel.
