When disassembly and maintenance are needed later, the bidirectional screw rod 206 is reversed to move the four connecting frames 203 away from the measuring pipe 1, and then the latches 304 are pulled out. The ultrasonic measuring instrument 305 is repaired and replaced without the need of using more reinforcing parts for reinforcement, and the staff does not need to perform complicated operation steps when disassembling and fixing, which improves the measurement efficiency of the equipment and the convenience of use. When the bidirectional screw rod 206 moves in the connecting groove 202 with the connecting strips 205, the two connecting strips 205 are limited by the connecting frames 203 on both sides of the installation base 201, so that they can stably slide forward and backward in the connecting groove 202 without motion interference.
