[0037] With reference to Figure 3 and Figure 6The plurality of clamping grooves 59 are evenly arranged on the outer side of the moving rod 53 and are matched with the limiting rods 57, so that the precise positioning of the moving rod 53 at different positions can be realized. The limiting rods 57 are inserted into the inner wall of the clamping grooves 59. The rear side of the moving rod 53 is arranged in a T shape. The T shape increases the contact area and friction force between the moving rod 53 and the inner wall of the extrusion plate one 55 and the extrusion plate two 56. When the position of the extrusion plate is adjusted by sliding the moving rod 53, the force can be more smoothly and stably transmitted, so that the action of the extrusion plate is more stable.

[0038] Referring to Figure 2 The inner wall of the moving block 2 is provided with a limiting assembly. The limiting assembly comprises an extrusion piece 71. The extrusion piece 71 is slidingly connected to the inner wall of the moving block 2. When it is necessary to adjust the position of the moving block 2, the extrusion piece 71 is pressed to overcome the elastic force of the compression spring two 72, so that the limitation of the moving block 2 is released. Therefore, the moving block 2 can be moved. The side close to the base 1 of the extrusion piece 71 is arranged in a circular arc surface, which is convenient for contacting the surface of the base 1. The outer side of the extrusion piece 71 is elastically connected to the moving block 2 through the compression spring two 72. The elastic force of the compression spring two 72 is provided for the extrusion piece 71. When the extrusion piece 71 is not subjected to external force, the limiting state of the moving block 2 can be maintained.

[0039] Working principle: in use, the size and shape of the sensor to be calibrated are observed. The limiting rod 57 is pressed to overcome the elastic force of the reset spring 58 and slide out of the clamping groove 59. The moving rod 53 is no longer fixed and can slide in the rotating shaft 52. The extrusion plate one 55 and the extrusion plate two 56 change the included angle. After adjusting to the appropriate position, the limiting rod 57 is released. The reset spring 58 pushes the limiting rod 57 to insert into the corresponding clamping groove 59. The position of the moving rod 53 is fixed. The preliminary size adaptation adjustment of the sensor is completed.

[0040] The driving motor 4 is started. The driving motor 4 drives the bidirectional threaded rod 3 to rotate. Since the bidirectional threaded rod 3 is threadedly connected with the support frame 51, the two groups of support frames 51 move axially along the bidirectional threaded rod 3 in the inner wall of the moving block 2. With the movement of the support frame 51, the whole clamping assembly is brought close to or away from the sensor until the extrusion plate one 55 and the extrusion plate two 56 contact and clamp the sensor. The anti-skid pads on the outer side of the extrusion plate increase the friction force with the surface of the sensor, so that the sensor is prevented from sliding during the clamping process.

[0041] When it is needed to rotate the rotating shaft 52 to adjust the angle of the pressing plate, the limiting member 61 is pushed to be separated from the current limiting groove 63 against the elastic force of the compression spring 62, the rotating shaft 52 is rotated to the appropriate angle, the limiting member 61 is released, and the limiting member 61 is clamped into the new limiting groove 63 under the action of the compression spring 62 to fix the rotating angle of the rotating shaft 52, so that the adjustment of the angle of the sensor is realized.

[0042] If the calibration environment requires adjustment of the position of the sensor, the pressing member 71 in the inner wall of the moving block 2 is pressed to separate the arc surface on the side of the pressing member 71 close to the base 1 from the limitation on the moving block 2 against the elastic force of the compression spring 72, so that the position of the moving block 2 on the base 1 can be moved. After being adjusted to the appropriate position, the pressing member 71 is released, the compression spring 72 pushes the pressing member 71 to reset, and the position of the moving block 2 is limited again, so that the adjustment of the position of the sensor is completed.

[0043] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the present application has been described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, should be included in the protection scope of the present application.
