[0023] Please refer to Figure 2 , Figure 5 and Figure 6 , the inner ring of the fixed arc block 301 is fixedly connected to the connection part of the driving shaft 1. Positioning blocks 304 are fixedly connected to the opposite sides of the fixed arc block 301 and the receiving arc block 303;

[0024] Please refer to Figure 2 , Figure 5 and Figure 6 , positioning grooves 302 that cooperate with the positioning blocks 304 are opened at the tops of the fixed arc block 301 and the receiving arc block 303. By arranging the positioning grooves 302 and the positioning blocks 304, it can play a role in positioning and installation, facilitating the quick docking of the fixed arc block 301 and the receiving arc block 303, and in the docking state, preventing the fixed arc block 301 and the receiving arc block 303 from randomly moving up and down. Guide heads 313 are fixedly connected to the tops of the connecting frame 306 and the magnetic attraction frame 310;

[0025] Please refer to Figure 2 , Figure 5 and Figure 6, receiving grooves 305 for cooperating with the guiding heads 313 are provided inside both the fixed arc block 301 and the receiving arc block 303. By providing the receiving grooves 305 and the guiding heads 313, the positioning and guiding effects can be achieved, the movement stability of the connecting frame 306 and the magnetic attraction frame 310 can be ensured, an annular groove 308 is provided on the outer ring of the auxiliary disc 307. By providing the auxiliary disc 307 and the annular groove 308, the bottom ends of the connecting frame 306 and the magnetic attraction frame 310 can be installed, and the rotational stability of the connecting frame 306 and the magnetic attraction frame 310 can be further improved;

[0026] Please refer to Figure 2 , Figure 5 and Figure 6 , an auxiliary rod 312 is fixedly connected to the outer ring of the bottom of the auxiliary disc 307. By providing the auxiliary rod 312, the displacement of the hexagonal block 309 can be guided to ensure the movement stability of the hexagonal block 309. A spring 311 is fixedly connected to the bottom of the auxiliary disc 307 and on the outer side of the auxiliary rod 312. By providing the spring 311, the hexagonal block 309 can be elastically supported, and the hexagonal block 309 can be prevented from moving downward randomly without external force;

[0027] Please refer to Figure 2 , Figure 5 and Figure 6 , the bottom of the spring 311 is fixedly connected to the surface of the hexagonal block 309, and the hexagonal block 309 is adapted to the hexagonal groove 6. By providing the hexagonal block 309 and the hexagonal groove 6, the positioning and anti-rotation effects can be achieved, and the auxiliary disc 307 and the hexagonal block 309 can be prevented from rotating randomly in the installed state;

[0028] Please refer to Figure 1 , Figure 5 and Figure 6 , the number of the connecting frames 306 is several, the number of the magnetic attraction frames 310 is two, and the connections between the anti-cut net cloth 2 and the connecting frames 306 and between the anti-cut net cloth 2 and the magnetic attraction frames 310 are all fixedly connected;

[0029] The magnetic attraction frame 310 includes an auxiliary frame having the same specification as the connecting frame 306, and a magnet is fixedly inlaid on the surface of the auxiliary frame. The two magnetic attraction frames 310 cooperate to form a closed shell in the contact magnetic attraction state in cooperation with the anti-cut net cloth 2 and several connecting frames 306, and the dispersion disc body 5 can be completely covered and protected;

[0030] The guiding head 313 includes a short rod and a guiding ball. The bottom of the short rod is fixedly connected to the connecting frame 306 or the magnetic attraction frame 310, the top of the short rod is fixedly connected to the guiding ball, and the specification of the guiding ball is larger than that of the short rod. With this design, when the guiding head 313 slides in the receiving groove 305, the guiding head 313 can be prevented from falling off;

[0031] The bottom ends of the connecting frame 306 and the magnetic attraction frame 310 both extend into the annular groove 308 and are in sliding contact with the annular groove 308. The bottom ends of the connecting frame 306 and the magnetic attraction frame 310 are both convexly designed, and their shapes are similar to those of the guiding heads 313. At the same time, the outer edge opening of the annular groove 308 is smaller than the size of the bottom protrusions of the connecting frame 306 and the magnetic attraction frame 310. This design can ensure the circumferential rotation stability of the connecting frame 306 and the magnetic attraction frame 310 and prevent the connecting frame 306 and the magnetic attraction frame 310 from detaching from the auxiliary disc 307;

[0032] The auxiliary rod 312 passes through the hexagonal block 309 and is in sliding contact with the hexagonal block 309;

[0033] A stud is fixedly connected to the bottom of the positioning head 4. The bottom of the stud penetrates to the bottom of the dispersion disc body 5 and is threadedly sleeved with a nut. In this way, the positioning head 4 can be stably connected to the dispersion disc body 5, so that the dispersion disc body 5 rotates together with the drive shaft 1.

[0034] In the covering and protecting state, the guiding head 313 at the top end of the left connecting frame 306 is located in the receiving arc block 303, and the bottom end of the left connecting frame 306 is located in the auxiliary disc 307, which can prevent the connecting frame 306 from detaching from the receiving arc block 303 and the auxiliary disc 307. Since the auxiliary disc 307 is in a fixed and integral state, the connecting frame 306 can only slide circumferentially in the annular groove 308 on the auxiliary disc 307 and cannot displace linearly. When the right connecting frame 306 is placed in the fixed arc block 301, the right connecting frame 306 cannot displace linearly, so the auxiliary disc 307 is restricted and cannot move left and right, and the receiving arc block 303 will also not be able to displace left and right.

[0035] During use, all components are in the initial state. A number of connecting frames 306 and magnetic attraction frames 310 are all located in the receiving grooves 305 on the receiving arc block 303. When it is necessary to protect the dispersion disc body 5 against the secondary high, the hexagonal block 309 is pulled down, so that the hexagonal block 309 moves downward and the spring 311 is stretched. Then the receiving arc block 303 is translated. Under the cooperation of the positioning groove 302 and the positioning block 304, the receiving arc block 303 is quickly and accurately docked with the fixed arc block 301. At this time, the hexagonal block 309 is aligned with the hexagonal groove 6. The hexagonal block 309 is released, and under the elastic connection of the spring 311, the hexagonal block 309 automatically moves upward and resets into the hexagonal groove 6 to prevent the auxiliary disc 307 from rotating circumferentially, moving left and right, and moving forward and backward. At this time, the staff member pulls the magnetic attraction frame 310, so that the magnetic attraction frame 310 slides in the receiving groove 305 and enters the fixed arc block 301 until the two magnetic attraction frames 310 come into contact and magnetically attract each other. At this time, the anti-cut net cloth 2 can completely cover and protect the dispersion disc body 5.

[0036] In summary, for the dispersion disc protection device, by setting the anti-cut mesh cloth 2, the covering protection component 3 and the hexagonal groove 6, the problems that the device cannot be shrunk and folded, occupies a fixed space, affects actual transportation and storage, and has certain limitations are solved.
