A fixing component for abutting against the inner wall of the slide groove is connected inside the hole. An adjusting ring is connected along the outer periphery of the fixing base. The adjusting ring has several through holes, which correspond to the slide grooves. An adjusting rod is connected inside each through hole. One end of the adjusting rod extends into its corresponding slide groove and contacts the sliding block. The other end of the adjusting rod is connected to a fixing plate. A return spring is fitted on the other end of the adjusting rod between the fixing plate and the adjusting ring. A positioning groove is provided on one end of the adjusting rod. A positioning bolt connected to the positioning groove passes through the adjusting ring.

[0022] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0023] Example
[0024] like Figure 1 , Figure 2 and Figure 3 As shown, an adjustment mechanism for a magnetic stress probe includes a fixed base 1, which is circular in structure. An excitation column 2 is connected to the center of the fixed base 1. Several induction columns 3 are connected along the circumference of the circular fixed base, and the induction columns 3 are spaced equidistantly. A coil 4 is connected to both the induction columns 3 and the excitation columns 2. A sliding groove 5 is formed in the radial direction of the fixed base 1, and the number of sliding grooves 5 is the same as the number of induction columns 3. A sliding block is slidably connected within each sliding groove 5. 6. The sensing column 3 is connected to the sliding block 6. The sliding block 6 has a fixing hole 7 on its side. A fixing component 8 for abutting against the inner wall of the slide groove 5 is connected in the fixing hole 7. An adjusting ring 9 is connected along the outer periphery of the fixing base 1. The adjusting ring 9 has several through holes 10. An adjusting component that makes the sliding block move at equal distances is connected to the adjusting ring through the through holes. The adjustment of the adjusting component corresponds to the movement of each sliding block. The fixed block is used to fix the moved sliding block in position, thereby realizing the detection of different products.
[0025] Furthermore, the adjustment assembly includes an adjustment rod, a fixed plate, a return spring, a positioning groove, and a positioning bolt. The adjustment rod 11 is connected inside the through hole 10. One end of the adjustment rod 11 extends into its corresponding sliding groove and contacts the sliding block 6. The other end of the adjustment rod 11 is connected to the fixed plate 12. A return spring 13 is fitted on the other end of the adjustment rod 11 between the fixed plate 12 and the adjustment ring 9. A positioning groove 14 is provided on one end of the adjustment rod 11. A positioning bolt 15 connected to the positioning groove passes through the adjustment ring 9.
[0026] The aforementioned positioning bolt is screwed onto the adjusting ring and tightened into the positioning groove. When the adjusting rod is not in use, the adjusting rod is retracted by the return spring, thereby ensuring that it will not come into contact with the sliding block.
[0027] Furthermore, the adjusting rod 11 is connected to a top block 16 that contacts the sliding block. The top block can improve the contact with the sliding block, thereby increasing the stability of the sliding block when it moves.
[0028] In this invention, the fixing component can lock the sliding block in a designated position, thereby allowing the sensing column on the sliding block to remain in the required position, which can be used for the detection of different products.
[0029] Furthermore, the fixing component 8 includes a fixing block 81, which is slidably connected to the fixing hole 7 opposite to the inner wall of the slide groove 5. A blocking block 82 is connected to the fixing block 81. A fixing spring 83 is fitted on the fixing block 81 between the blocking block 82 and the inner wall of the slide block 6. A fixing bolt 84 is connected to the fixing hole 7. An abutment block 85 is connected to the lower end of the fixing bolt 84 that contacts the blocking block 82.
[0030] The contact block 85 has a conical structure. When the contact block is twisted, the conical part will contact the fixing block, causing the fixing block to protrude out of the fixing hole and contact the inner wall of the slide groove. At the same time, the fixing block is provided with anti-slip stripes, which can effectively improve the contact with the inner wall of the slide groove and improve the stability of the sliding block.
[0031] Furthermore, the fixing hole 7 has an L-shaped structure. The L-shaped fixing hole can make the fixing block contact the inner wall of the slide groove, and can also screw the abutment block onto the sliding block. It makes full use of its structure, ensuring fixation while reducing the usable area.
[0032] The adjusting ring 9 of this utility model is connected to the fixed base 1 by fixing screws. The adjusting ring is locked to the fixed base by fixing screws. When the fixed base is working, the adjusting ring can be removed. At the same time, the adjusting ring can be adjusted to the corresponding position according to the position of the slide groove, so that the adjusting component corresponds to the sliding block.
[0033] The working principle of this utility model is as follows:
[0034] In practice, when installing the fixed base, connect the adjusting ring to the fixed base and extend the adjusting rod into the corresponding slide groove. Then, adjust the position of the sliding block in the slide groove by adjusting the adjusting rod in turn. After confirming the position of the sliding block, lock the adjusting rod in the designated position by the positioning bolt and positioning groove, so that the position of each sliding block is kept at the same distance. Finally, lock the sliding block in the slide groove by the fixing component.
[0035] The working principle of this utility model has been disclosed (publication number: CN210346952U), and will not be described in any further detail.
[0036] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0037] In the description of this application, it should be noted that the terms "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0038] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or vertical, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.
