Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Please refer to Figure 1 - Figure 6 This utility model provides the following technical solution: an easily adjustable magnetic field probe, including a base 1, a support column 2 fixedly connected to the top of the base 1, and the base 1 and the support column 2 being vertically distributed; an extension rod 4 is installed inside the mounting slider 3, an adjusting sleeve 5 is slidably connected to the outside of the extension rod 4, and an angle adjustment structure is installed on the outside of the adjusting sleeve 5, the angle adjustment structure including a connecting block 8 rotatably connected to the outside of the adjusting sleeve 5, and a first worm gear 9 fixedly connected at the connection between the connecting block 8 and the adjusting sleeve 5, a first worm 7 rotatably connected to one side of the adjusting sleeve 5, and the outside of the first worm 7 and the outside of the first worm gear 9 meshing with each other; a quick-connect structure is installed at the end of the connecting block 8 away from the first worm gear 9, and a height adjustment structure for adjusting the bracket is installed inside the support column 2 and the mounting slider 3.

[0027] When the device is in use, the probe body 13 will be mounted on the extension rod 4. By rotating the first worm 7, the first worm wheel 9 will be driven to rotate. At this time, the first worm wheel 9 will drive the connecting block 8 to rotate around the adjusting sleeve 5. Since the first worm 7 and the first worm wheel 9 are self-locking, when the connecting block 8 stops rotating with the first worm wheel 9, the angle of the connecting block 8 will be fixed, thereby fixing the angle of the mounting sleeve 10 installed on one side of the connecting block 8 and the probe body 13, and thus adjusting the tilt angle of the probe body 13.

[0028] Example 2: Based on Example 1, a quick-connect structure and a height adjustment structure are also disclosed. The specific structures are as follows: The quick-connect structure includes a mounting sleeve 10 fixedly connected to one side of the connecting block 8, and a probe body 13 is slidably connected inside the mounting sleeve 10; a clamping slider 11 is slidably connected inside the mounting sleeve 10, and the clamping slider 11 and the mounting sleeve 10 are engaged with each other on the lower outer side of the probe body 13; a spring 12 is fixedly connected between the clamping slider 11 and the connecting block 8, and the top of the clamping slider 11 extends to the outer side of the top of the mounting sleeve 10; a slot is provided in the middle of the top of the extension rod 4, and a self-tightening screw 6 is engaged inside the slot. The self-tightening screw 6 is threadedly connected to the middle of the top of the adjustment sleeve 5, and the lower end of the self-tightening screw 6 passes through the top of the adjustment sleeve 5 and interacts with the slot at the top of the extension rod 4. The height adjustment structure includes a mounting slider 3 slidably connected inside the base 1, and two symmetrically distributed sliding rods are provided inside the mounting slider 3, and a vertically distributed sliding rod is fixedly connected to one side of the support column 2; the sliding rod is slidably connected to the inside of the mounting hole 15, and a lead screw 14 is rotatably connected inside the support column 2, and the lead screw 14 is threadedly connected to the inside of the mounting hole 15; the mounting slider 3 has a hollow structure inside, and a second worm gear 16 is fixedly connected in the middle inside the mounting slider 3; a second worm 17 is rotatably connected inside the mounting slider 3, and the outer side of the second worm 17 is in contact with the outer side of the second worm gear 16; a bevel tooth is fixedly connected to one end of the second worm 17, and the second worm 17 meshes with a rotating shaft 18 through the bevel tooth, and the rotating shaft 18 and the second worm 17 are distributed with bevel teeth.

[0029] The lower end of the probe body 13 is installed inside the mounting sleeve 10 via a detachable structure. A clamping slider 11 is slidably connected inside the mounting sleeve 10, and a spring 12 between the clamping slider 11 and the mounting sleeve 10 always drives the clamping slider 11 to slide closer to the mounting sleeve 10 and away from the connecting block 8. Since the top of the clamping slider 11 extends to the outer side of the top of the mounting sleeve 10, the extended part of the clamping slider 11 forms a handle. By pulling the clamping slider 11, it is separated from the inner end of the mounting sleeve 10, thereby separating the clamping slider 11 and the probe body 13. At this time, the probe body 13 can be taken out from inside the mounting sleeve 10. When the probe body 13 is installed inside the clamping slider 11, the spring 12 will drive the clamping slider 11 and the lower end of the probe body 13 to engage with each other, thereby fixing the lower end of the probe body 13 through the mounting sleeve 10 and the clamping slider 11. Thus, by controlling the clamping slider 11, the probe body 13 can be quickly disassembled, which is convenient for replacing probe bodies 13 of different specifications.

[0030] By rotating the self-tightening screw 6, the lower end of the probe body 13 is separated from the slot at the top of the extension rod 4. At this time, the sliding adjustment sleeve 5 is adjusted to adjust its position outside the extension rod 4, thereby adjusting the position of the probe body 13 outside the extension rod 4. At the same time, the screw 14 rotates inside the mounting hole 15, thereby driving the mounting slider 3 to move up and down inside the support column 2. With the adjustment sleeve 5 moving outside the extension rod 4, the probe body 13 can be adjusted to any position within the plane formed by the extension rod 4 and the support column 2.

[0031] Rotating the rotating shaft 18 drives each bevel tooth to rotate, which in turn drives the second worm gear 17 to rotate. Simultaneously, the rotation of the second worm gear 17 drives the second worm wheel 16 to rotate inside the mounting slider 3. During the rotation of the second worm wheel 16, the angle between the extension rod 4 and the mounting slider 3 will change. At this time, the rotation direction of the extension rod 4 and the rotation direction of the connecting block 8 are perpendicular to each other, thereby adjusting the orientation of the probe body 13.

For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
