Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe.
Fig. 1-2 is referred to, the utility model includes tables 1 and positive and negative switch 16, and the bottom of tables 1 is provided with four supports
Leg, supporting leg bottom are provided with slipmat, and the middle position of tables 1 opens up fluted, and is plugged with major axis through rotation in groove
2, the upper end of major axis 2 is connected with the bottom of supporting table 14, and the top of supporting table 14 is rotatably connected to dispenser 15 by screw, branch
The intracavity bottom of support platform 14 is provided with permanent magnet 12, and supporting table 14 is arranged right below electromagnet 11 and spring 13, the He of electromagnet 11
Spring 13 and in the grooves, the number of electromagnet 11 and spring 13 at least six, and the annular point centered on major axis 2
Cloth.
The lower end of major axis 2 is fixedly connected with limited block 3, and the side wall of major axis 2 is connected with fixture block 10, and the number of fixture block 10 has six
It is individual, and angularly annular spread is presented between fixture block 10, the activity of major axis 2 is plugged in sleeve 4, and the madial wall of sleeve 4 opens up
There is a neck 5 that clamping is matched with fixture block 10, the upper end of sleeve 4 and the lower surface rotation connection of tables 1, the lower end of sleeve 4 and the
