[0037] A plurality of assembly holes are provided between the rotating portion 3 and the output end of the driving mechanism 2.

[0038] The top of the base portion 1 is provided with an annular rotating groove 4, and a connecting member 5 is installed on the lower side of the rotating portion 3. The connecting member 5 extends into the rotating groove 4 and is slidably connected to the rotating groove 4;

[0039] A plurality of electromagnetic drive structures 6 are installed inside the rotating tank 4. The output end of each electromagnetic drive structure 6 is directed toward each connecting member 5, and a friction member 7 is installed between them.

[0040] Each electromagnetic drive structure 6 adopts a mature structure in the existing technology to reduce production costs;

[0041] The friction member 7 is provided with a magnetic portion that contacts the electromagnetic drive structure 6. When each electromagnetic drive structure 6 is activated, magnetism is generated. The magnetic portion of the friction member 7 pushes the friction member 7 toward the connecting member 5. The connecting member 5 reinforces the drive mechanism 2, thereby improving the firmness of the rotating part 3 when the drive mechanism 2 is not activated.

[0042] A plurality of elastic members 8 are installed between the lower side of the friction member 7 and the bottom of the rotating groove 4. The elastic member 8 includes a first column and a second column. The top end of the first column is fixedly connected to the friction member 7, and the bottom end of the second column is fixedly connected to the bottom of the rotating groove 4.

[0043] The first column is slidably connected to the corresponding second column, and a spring is installed between them;

[0044] After the electromagnetic drive structure 6 stops working, each elastic member 8 resets the friction member 7 to prevent the friction member 7 from continuing to contact the connecting member 5.

[0045] See also Figure 2 , a sliding groove is provided on the outer side of the connecting member 5;

[0046] An annular reinforcement member 9 is installed inside the rotating groove 4 , and the reinforcement member 9 is slidably connected to the sliding groove of the connecting member 5 .

[0048] One end of each locking member 11 located inside the base portion 1 is rotatably connected to the corresponding reinforcement plate 10;

[0049] When the locking member 11 rotates along the base portion 1 , the reinforcing plates 10 are driven to slide. When each reinforcing plate 10 slides to one side of the driving mechanism 2 , the driving mechanism 2 is reinforced.

[0050] The connecting member 5 is provided with a plurality of extension portions extending to the upper side of the base portion 1;

[0051] A plurality of receiving grooves are provided on the lower side of the rotating portion 3 , and the size and distribution position of each receiving groove correspond to the size and distribution position of each extending portion of the connecting member 5 .

[0055] While working:

[0056] Assemble the receiving grooves in the rotating part 3 with the extension parts of the connecting member 5 respectively. After assembly, first fix the rotating part 3 to the output end of the driving mechanism 2, and then use bolts to penetrate the corresponding first screw holes and second screw holes to fix each extension part to the receiving groove.

[0057] Finally, rotate each locking member 11 to move the corresponding reinforcement plate 10 to one side of the driving mechanism 2 to reinforce the driving mechanism 2;

[0058] During use, the driving mechanism 2 drives the rotating part 3 to rotate. After the rotation, each electromagnetic driving structure 6 is activated to move the friction member 7. The friction member 7 moves to the lower side of the connecting member 5 by stretching each elastic member 8 and contacts the connecting member 5. The friction between the friction member 7 and the connecting member 5 improves the firmness of the rotating part 3.

[0059] Subsequently, before the driving mechanism 2 needs to rotate the rotating part 3 , each electromagnetic driving structure 6 stops working, and each elastic member 8 resets the friction member 7 to cut off the friction between the friction member 7 and the connecting member 5 .
