The other ends of the first springs 12 are fixed to the moving plate 9. A square rod 15 is slidably connected inside the rotating rod 7. A knob 16 is fixed at one end of the square rod 15. A plug rod 17 is fixed on the side of the knob 16 close to the shell 6. A slot 18 is opened on one side of the shell 6. The plug rod 17 is sleeved inside the slot 18. By pulling the knob 16 to drive the square rod 15 to move outwards, the plug rod 17 is disengaged from the inside of the slot 18, so that the knob 16 can be rotated. By twisting the knob 16 to drive the rotating rod 7 to rotate, and at the same time the elliptical plate 8 rotates, the limitation of the moving plate 9 is released. By the resilience of the first spring 12, the moving plate 9 is pushed to drive the limiting rod 10 to disengage from the inside of the limiting groove 11.

[0026] Working principle: The user drives the square rod 15 to move outwards by pulling the knob 16, so that the insertion rod 17 disengages from the inside of the slot 18, enabling the knob 16 to rotate. By twisting the knob 16, the rotating rod 7 is driven to rotate, and at the same time, the elliptical plate 8 rotates to release the limit on the moving plate 9. The moving plate 9 is pushed by the resilience of the first spring 12 to drive the limit rod 10 to disengage from the inside of the limit slot 11. At this time, the height of the reflector 5 can be adjusted and fixed. By adjusting the reflector 5 up and down and cooperating with the scale lines 22 provided on both sides of the support plate 2, it is convenient to calculate the accuracy of the measurement by the ultrasonic instrument 4, thus ensuring the accuracy of the measurement result. The structure is compact and convenient to operate. By setting the structure of the L-shaped rod 13 and the through groove 14, the movement track of the moving plate 9 can be restricted to avoid tilting, which affects the accuracy of the measurement. By setting the structure of the sliding groove 19 and the slider 20, the moving direction of the square rod 15 can be restricted to prevent the user from exerting too much force when pulling the knob 16 and causing the square rod 15 to disengage from the inside of the rotating rod 7. By setting the second spring 21, the resilience of the second spring 21 can be used to constrain the position of the insertion rod 17, saving manpower when fixing the knob 16.
