Alternatively, the groove of indent is provided with the outside of the support.
Alternatively, the support is integrally formed with cavity.
Magnetic of the present utility model rule, magnet assembly is fixed in the cavity that magnetic advises by adsorption magnet, can avoid because
The contradiction with magnetic rule cavity secure fit caused by washer, magnet tolerance.And when washer, magnet positioning bonding are in frame
Afterwards, the absorption affinity between adsorption magnet and washer, magnet 8 can be overcome easily, magnetic rule is departed from magnetic circuit system.
It is of the present utility model other by referring to the drawings to the detailed description of exemplary embodiment of the present utility model
Feature and its advantage will be made apparent from.

The description only actually at least one exemplary embodiment is illustrative to be never used as to this practicality below
New and its application or any restrictions used.
It may be not discussed in detail for technology and equipment known to person of ordinary skill in the relevant, but in appropriate situation
Under, the technology and equipment should be considered as part for specification.
In shown here and discussion all examples, any occurrence should be construed as merely exemplary, without
It is as limitation.Therefore, other examples of exemplary embodiment can have different values.
It should be noted that：Similar label and letter represents similar terms in following accompanying drawing, therefore, once a certain Xiang Yi
It is defined, then it need not be further discussed in subsequent accompanying drawing in individual accompanying drawing.
With reference to figure 1, Fig. 2, the utility model provides a kind of magnetic rule, and it includes being used for what is be combined together with magnet assembly
Cavity 1, size, the shape of the side wall of cavity 1 are configurable for positioning the magnetic gap of magnetic circuit system.
Fig. 2 shows it is schematic diagram of the utility model magnetic rule when positioning magnetic circuit system, and the magnetic circuit system shown in Fig. 2 is
Internal magnetic circuit structure, to those skilled in the art, magnetic rule of the present utility model can be also used for external magnetic circuit, two magnetic route structure
Positioning.For the ease of description, now magnetic of the present utility model rule are introduced in detail by taking the internal magnetic circuit shown in Fig. 2 as an example.
Specifically, the cavity 1 has a hollow inner chamber, its inwall 3 be used for outside the washer 9 in magnetic circuit system, magnet 8
Wall is combined together, and its outer wall 2 is used to be combined together with the inwall of frame 7 in magnetic circuit system.The outer wall 2, interior advised by magnetic
Wall 3 defines the shape of the magnetic gap of magnetic circuit system, size.
Magnetic rule of the present utility model, in addition to the support to be linked together positioned at the upper end of cavity 1 with the cavity 1, and
It is arranged on the adsorption magnet 5 that the upper end of cavity 1 is used to adsorb magnet assembly in cavity 1.Support of the present utility model and cavity 1 can be with
It is integrally formed, the support can play a part of handle, so that operator operates magnetic rule.
Adsorption magnet 5 of the present utility model can be arranged directly on the upper end of cavity 1；It is preferable in the utility model one
