[0031] In this embodiment, the tailstock 7 is in a convex shape, and three support frames 9 are respectively installed in three directions of the convex shape of the tailstock 7.

[0032] In this embodiment, the clamping slide cavity 71 and the head of the base 2 are both semicircular, which is convenient for processing and for limiting the matching accuracy between the base 2 and the tail stock 7 during the up and down sliding process of the base 2 pushed into the clamping slide cavity 71.

[0033] In this embodiment, the cross section of the lower part of the support frame 9 is waist-shaped, so that the positional relationship between the support frame 9 and the measuring rod 6 is limited by the shape of the cross section of the support frame 9 during the movement of the measuring rod 6 mounted on the support frame 9.

[0034] In this embodiment, a base column 21 is disposed on the base 2 , the axis of the base column 21 is perpendicular to the surface of the base 2 , and the nozzle head 101 can be sleeved on the base column 21 .

[0035] In this embodiment, the measuring rod 6 is divided into two sections with the rotating axis 61 as a node, and the distance of the front section of the measuring rod 6 is one quarter of the distance of the rear section, so that the movement distance of the front end of the measuring rod 6 is magnified four times by the measured rear end, which is convenient for observing the distance change of the spherical side head of the front end of the measuring rod 6 in the measured hole 102.

[0036] In this embodiment, the guide slide cavity 32 is in an open circular shape, so that when the spherical slider 62 slides in the guide slide cavity 32, the distance from the center of the spherical slider 62 to the surface of the guide slide cavity 32 is always the same, and limit plates 33 are provided at both ends of the guide slide cavity 32 to limit the sliding distance of the spherical slider 62 in the guide slide cavity 32.

[0037] In this embodiment, the calibration disc 3 is in the shape of a ring, and the guide slide cavities 32 are arranged in three adjacent 120° angles.

[0038] In this embodiment, there is an air bubble in the middle of the level measuring plate 5, and whether the level measuring plate 5 is in a horizontal state can be determined by the air bubble.

[0039] In this embodiment, the spherical probe 8 is spherical, so that the distance from the surface of the spherical probe 8 to the center of the sphere is the same. When the measuring rod 6 drives the spherical probe 8 to move through the rotating shaft 61, the spherical probe 8 can always fit on the inner wall of the measured hole 102.

[0040] When using

[0041] First, the nozzle head 101 is put on the base column 21, and then the base 2 is pushed into the clamping slide cavity 71 of the tail stock 7. Further, the measured hole 102 is aligned with the spherical probe 8, and at the same time, the moving magnetic ring 22 on the base 2 is attracted to the fixed magnetic ring 23 on the tail stock 7.

[0042] Furthermore, under the action of gravity, the calibration disc body 3 drives the spherical probes 8 at the front ends of the three measuring rods 6 to simultaneously fit against the side walls of the measured holes 102 close to the center axis of the nozzle head 101. During this process, the spherical slider 62 at the end of the measuring rod 6 slides in the guide slide cavity 32. At this moment, when the distances from the three measured holes 102 of the nozzle head 101 to the center axis of the nozzle head 101 are different, the measuring rod 6 will transmit the detected size difference to the end of the measuring rod 6, and the movement distance of the front end of the measuring rod 6 will be magnified four times by the measured rear end, so that the calibration disc body 3 will be distorted under the support of the three measuring rods 6, so that the calibration disc body 3 drives the horizontal measuring disc 5 to distort, that is, by observing whether the horizontal measuring disc 5 is horizontal, it is determined whether the distances from the side walls of the three measured holes 102 of the nozzle head 101 close to the center axis of the nozzle head 101 to the center axis of the nozzle head 101 are the same.

[0043] Further, the active magnetic ring 4 is pressed, at this moment the active magnetic ring 4 will attract the passive magnetic ring 31 to make the passive magnetic ring 31 drive the calibration disk 3 to lift, so that the calibration disk 3 drives the measuring rod 6 to move, that is, the measuring rod 6 drives the spherical measuring heads 8 at the front ends of the three measuring rods 6 to simultaneously fit the side wall of the measured hole 102 away from the central axis of the nozzle head 101, and in this process, the spherical slider 62 at the end of the measuring rod 6 slides in the guide slide cavity 32; at this moment, when the distances from the three measured holes 102 of the nozzle head 101 to the central axis of the nozzle head 101 are different, the calibration disk 3 drives the horizontal measuring disk 5 to tilt, that is, by observing whether the horizontal measuring disk 5 is horizontal, it is determined whether the distances from the side walls of the three measured holes 102 of the nozzle head 101 away from the central axis of the nozzle head 101 to the central axis of the nozzle head 101 are the same.

[0044] Furthermore, when the distances from the ends of the three measured holes 102 side walls away from the central axis of the nozzle head 101 and the distances from the ends of the three measured holes 102 side walls close to the central axis of the nozzle head 101 to the central axis of the nozzle head 101 are respectively the same, that is, the diffusion hole positions of the nozzle head 101 meet the detection requirements, so that the milk foam can be kept thick and mellow during the milk frothing process of the nozzle head 101, the detection design is ingenious, the operation is simple, and it is easy to use.
