[0021] The first tension spring 603 is fixedly connected to the inner wall of the placement groove 5 on one side thereof. By setting the positioning mechanism 6, the positioning rod 601 can cooperate with the connecting plate 3 and the transducer seat 2 to quickly assemble and fix the transducer 4 to the ultrasonic measuring meter 1, thereby avoiding the problem that the transducer 4 cannot be quickly installed when docking with the ultrasonic measuring meter 1. The transmission mechanism 7 includes a square plate 701, two traction rods 702, a movable block 703, a transmission rod 704 and a second tension spring 705. The square plate 701 is located at the front side of the inner cavity of the placement groove 5 and is fixedly connected to the inner wall of the placement groove 5. The two traction rods 702 are movable blocks 703, a transmission rod 704 and a second tension spring 705. The square plate 701 is located at the front side of the inner cavity of the placement groove 5 and is fixedly connected to the inner wall of the placement groove 5. The traction rods 702 are respectively located on the left and right sides of the top of the square plate 701 and are movably connected to the top of the square plate 701 through a rotating shaft.

By setting the movable hole 14, the movable hole 14 avoids the transmission rod 704 from contacting the inner wall of the transducer seat 2 during movement to generate friction.

[0023] The working principle of the utility model is as follows: when in use, the transmission rod 704 is pushed backward to move, and the transmission rod 704 will drive the movable block 703 to move during the movement, and the movable block 703 will stretch the second tension spring 705 when moving, and contact with the surface of the traction rod 702 and apply force to the traction rod 702, and the traction rod 702 will rotate through the connection point with the rotating shaft of the square plate 701 after being applied force, and the traction rod 702 will drive the connecting rod 602 to move through the connection end with the connecting rod 602 and the active trajectory of the inner cavity of the connecting rod 602 when rotating, and the connecting rod 602 will stretch the first tension spring 603 and drive the positioning rod 601 to move during the movement, and after the positioning rod 601 moves to a suitable position, the transducer 4 is docked with the ultrasonic measuring meter 1.

[0024] During the docking process, the connecting plate 3 will fit with the surface of the transducer seat 2. After the docking is completed, the transmission rod 704 is loosened, and the tension of the second tension spring 705 is contracted, which will quickly drive the movable block 703 to reset. During the resetting process of the movable block 703, the traction rod 702 will lose the stressed state. After the traction rod 702 loses the stressed state, the tension of the first tension spring 603 is contracted, which will quickly drive the positioning rod 601 to insert into the inner cavity of the positioning groove 13 through the connecting rod 602. After the positioning rod 601 is inserted into the inner cavity of the positioning groove 13, the transducer 4 and the ultrasonic measuring meter 1 can be quickly assembled and fixed through the cooperation of the connecting plate 3 and the transducer seat 2.
