Therefore, the technical solution of this embodiment effectively solves the problem of poor versatility of the stop nut removal tool in the related art.

[0031] like Figures 1 to 3 as well as Figure 6 As shown, in this embodiment, a plurality of mounting grooves 30 are symmetrically arranged, and the angles between any two adjacent mounting grooves 30 are equal. The above arrangement enables the limit column 40 to cooperate with the stop nut, thereby ensuring the disassembly and assembly of the stop nut.

[0032] like Figures 1 to 3 as well as Figure 6As shown, in this embodiment, the adjusting part 20 includes an adjusting disk 21, and a avoidance hole 211 is provided at the center of the adjusting disk 21. The adjusting disk 21 has a simple structure and good structural strength, and the avoidance hole 211 can avoid the stud.

[0033] Specifically, the adjustment disk 21 is a circular disk.

[0034] like Figures 1 to 5 As shown, in this embodiment, the stop nut disassembly tool further includes a magnetic structure 50, which includes a magnetic member 51 and a magnetic member 52 for magnetic attraction. The slot wall of each installation slot 30 is provided with a magnetic member 51, and each limit column 40 is provided with a magnetic member 52.

The width of the mounting hole gradually increases in the direction from the sleeve to the arm body. The third large diameter section can pass through the mounting hole at the maximum width of the mounting hole so that the second small diameter section is located in the mounting hole. The arm body is then adjusted so that the second small diameter section is located at the minimum width of the mounting hole, thereby making the position of the limiting column 40 more stable.

[0046] A screw is arranged between the arm body and the sleeve to lock the position between the arm body and the sleeve.

[0047] It should be noted that the structures of the second limiting arm 72 , the third limiting arm 73 and the fourth limiting arm 74 are the same as that of the first limiting arm 71 .

Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0049] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0050] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0051] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
