The limiting frame 813 is slidably connected to the middle part of the microscope main body 1. An L-shaped plate 814 is arranged through the limiting frame 813. One side of the L-shaped plate 814 is fixedly connected with a first damping rod 815. The end of the first damping rod 815 away from the limiting frame 813 is fixedly connected with one side of the L-shaped plate 814. The surface of the first damping rod 815 is sleeved with a first spring 806. One end of the first spring 806 is fixedly connected with one side of the limiting frame 813. The end of the first spring 806 away from the limiting frame 813 is fixedly connected with one side of the L-shaped plate 814 close to the limiting frame 813. After the support frame 802 is taken away from the water surface, the L-shaped plate 814 is manually inserted through one side of the limiting frame 813. Then the L-shaped plate 814 is pulled towards the limiting frame 813 through the first spring 806. Thus the L-shaped plate 814 is limited in the limiting frame 813. In this way, the moving block 812 can be limited on one side of the limiting frame 813 close to the middle part of the microscope main body 1 through the L-shaped plate 814. Thus the support frame 802 can be well away from the water surface. In this way, the part can be well drained.

[0035] With reference to Figure 7 and Figure 8The limiting device 9 comprises two moving frames 901, both of which are slidingly sleeved on the surface of the support frame 802, and the opposite surfaces of the two moving frames 901 are fixedly connected with rubber plates 904; when the limiting device 9 is used, the moving frames 901 are controlled to slide on the surface of the support frame 802, so that the two moving frames 901 clamp the part, and the rubber plates 904 are pressed on one side of the part, so as to avoid that the part moves on the top of the support frame 802 when the part is moved by the support frame 802; the inner wall of the moving frame 901, close to one side of the microscope main body 1, is fixedly connected with a second damping rod 902, one side of the second damping rod 902, away from the moving frame 901, is fixedly connected with the inner wall of the middle section of the support frame 802; the surface of the second damping rod 902 is sleeved with a second spring 903, one end of the second spring 903 is fixedly connected with one side of the inner wall of the middle section of the support frame 802, and the end of the second spring 903, away from the middle section of the support frame 802, is fixedly connected with one side of the moving frame 901; the moving frame 901 is pulled towards the middle position of the support frame 802 by the second spring 903, so that the moving frame 901 can be well pressed on one side of the part; the bottom of the moving frame 901 is provided with a rotating groove 906, the inner wall of the rotating groove 906 is fixedly connected with a rotating rod 907, the surface of the rotating rod 907 is rotatably sleeved with a rotating plate 908, one end of the moving frame 901, close to the second damping rod 902, is fixedly connected with a baffle 909, the baffle 909 is arranged on one side of the rotating plate 908, one side of the baffle 909 is provided with a rectangular block 905, and the rectangular block 905 is fixedly connected with one side of the inner wall of the support frame 802; the top of the rotating plate 908 is fixedly connected with an elastic rope 910, and one end of the elastic rope 910, away from the rotating plate 908, is fixedly connected with the top of the inner wall of the rotating groove 906; when the moving frame 901 moves on the surface of the support frame 802 towards the middle of the support frame 802, the rotating plate 908 is pressed and rotated on the surface of the rotating rod 907, so that the moving frame 901 can move towards the middle of the support frame 802; when the moving frame 901 is pressed on the surface of the part, the baffle 909 clamps the rotating plate 908, so that the rotating plate 908 cannot rotate on the surface of the rotating rod 907, and the moving frame 901 is limited on one side of the part to a certain extent; when it is needed to move the moving frame 901 back to the original position, the rotating plate 908 is manually controlled to be parallel to the ground, so that the rotating plate 908 can be stored in the rotating groove 906, and the moving frame 901 can be controlled to return to the original position.

[0036] The working principle is that when using the ultrasonic microscope, water is added to the inside of the microscope body 1, and then the part to be detected is placed at the bottom of the water. Then the detection head 3 is squeezed forward and backward by the second hydraulic device 5, and the detection head 3 is squeezed left and right by the first hydraulic device 4, so that the ultrasonic waves emitted by the detection head 3 can pass through every position of the part, and the inside of the part can be well seen through the display screen 7. In this way, the part can be directly observed to see whether it meets the specifications. When using the moving device 8, because the U-shaped plate 809 is away from the water surface, the U-shaped plate 809 is manually controlled to slide on the inner wall of the limiting groove 808. Because the gear 811 and the clamping block 810 are engaged with each other, the gear 811 can well drive the round rod 803 to rotate, so that the connecting rope 807 is wound around the surface of the round rod 803 provided on the inner wall of the groove 805, and then the connecting rope 807 pulls the support frame 802. In this way, the support frame 802 can well slide upward on the inner wall of the sliding groove 801, so that the support frame 802 can well move away from the water surface. After the support frame 802 is taken away from the water surface, the L-shaped plate 814 is manually inserted through one side of the limiting frame 813, and then the L-shaped plate 814 is pulled towards the limiting frame 813 by the first spring 806. In this way, the L-shaped plate 814 can limit the moving block 812 on one side of the limiting frame 813 close to the middle of the microscope body 1, so that the support frame 802 can well move away from the water surface. In this way, the part can be well drained, so that the part can be taken after it is completely drained. In this way, the water in the microscope body 1 can be prevented from being taken out to a certain extent. When the part needs to be placed at the bottom of the water, the round rod 803 is rotated in the opposite direction, so that the third spring 804 pulls the support frame 802 downward, and at the same time the connecting rope 807 moves away from the round rod 803. In this way, the support frame 802 can well slide downward on the inner wall of the sliding groove 801, so that the support frame 802 and the part provided on the top thereof can be well set at the bottom of the water. When using the limiting device 9, the moving frame 901 is pulled towards the middle position of the support frame 802 by the second spring 903, so that the moving frame 901 can well press on one side of the part. The two moving frames 901 clamp the part, and the rubber plate 904 presses on one side of the part, so that the part can be prevented from moving on the top of the support frame 802 when the support frame 802 moves. When the moving frame 901 moves towards the middle of the support frame 802 on the surface of the support frame 802, the rotating plate 908 is pressed to rotate on the surface of the rotating rod 907, so that the movement of the moving frame 901 towards the middle of the support frame 802 is not affected. When the moving frame 901 presses on the surface of the part, the baffle 909 clamps the rotating plate 908, so that the rotating plate 908 cannot rotate on the surface of the rotating rod 907, thereby limiting the moving frame 901 on one side of the part to a certain extent. When the moving frame 901 needs to return to the original position,The manual control rotating plate 908 is parallel to the ground, so that the rotating plate 908 is stored in the inside of the rotating groove 906, so that the moving frame 901 is controlled to return to the original position.
