Specific embodiment:
To make the objectives, technical solutions and advantages of the present invention clearer, below by shown in the accompanying drawings
Specific embodiment describes the utility model.However, it should be understood that these descriptions are merely illustrative, and it is not intended to limit this reality
With novel range.In addition, in the following description, descriptions of well-known structures and technologies are omitted, to avoid unnecessarily mixing
Confuse the concept of the utility model.
Here, it should also be noted that, in order to avoid having obscured the utility model because of unnecessary details, in the accompanying drawings
It illustrate only the structure and/or processing step closely related with scheme according to the present utility model, and be omitted practical with this
The little other details of new relationship.
As shown in Figure 1, Figure 2, Figure 3 shows, present embodiment use following technical scheme: it include frame 1, waffle slab 2,
Rack 3, coordinate points attracting device 4；The inside of frame 1 is provided with waffle slab 2, and waffle slab 2 is internally provided with actuation plate, frame
The downside of frame 1 is provided with mounting groove, and rack 3 is equipped in mounting groove, and rack 3 is internally provided with coordinate points attracting device 4,
Coordinate points attracting device 4 is pull-in on waffle slab 2, and grid lines and coordinate, while the inside of waffle slab 2 are provided on waffle slab 2
Be provided with actuation block, be attracted the actuation that block is able to achieve magnet, the coordinate points attracting device 4 include shell 5, spring return type around
Line roller 6, insertion pipe 8, lock plunger 9, grafting set 10, is attracted magnet 11 at bracing wire 7；The bottom of shell 5, which is equipped with, is attracted magnet 11,
