[0022] Referring to Figures 1 - 4 , a lightweight high-speed motor with good stability, including a high-speed motor body 9. A base 8 is sleeved outside the high-speed motor body 9. A plurality of first fixing plates 5 are welded on the upper surface of the base 8. Threaded holes are provided on one side of the plurality of first fixing plates 5. A threaded rod 11 is threadedly connected in the threaded holes. One end of the threaded rod 11 is rotatably connected to a connecting plate 7 that moves horizontally along the base 8. Two clamping blocks 4 are welded on one side of the connecting plate 7. A plurality of clamping grooves 3 are provided on the circumferential outer wall of the high-speed motor body 9, and the clamping blocks 4 are clamped with the clamping grooves 3. Through the clamping of the clamping blocks 4 and the clamping grooves 3, the base 8 and the high-speed motor body 9 are connected. A chute 15 is provided at one end of the threaded rod 11. A square block 14 is slidably connected in the chute 15. A magnetic block 12 that adsorbs to the threaded rod 11 is adhered to one end of the square block 14. A plurality of second fixing plates 6 are welded on the upper surface of the base 8, and the threaded rod 11 passes through the second fixing plates 6. Grooves 13 are provided on one side of the plurality of second fixing plates 6, and the magnetic block 12 is clamped with the grooves 13. Through the clamping of the magnetic block 12 and the grooves 13, the threaded rod 11 is fixed, so that the threaded rod 11 will not rotate under the vibration of the motor, thereby enabling the base 8 to be stably connected to the motor, and improving the connection stability between the motor and the base 8.

[0023] In this utility model, a tension spring 16 is welded to the end of the square block 14 away from the magnetic block 12, and the tension spring 16 is fixed to the threaded rod 11. The tension spring 16 will be stretched during the process of pulling the square block 14 to move, and the magnetic block 12 will reset under the action of the tension spring 16. A plurality of positioning rods 1 are welded on the circumferential outer wall of the high-speed motor body 9. A plurality of notches 2 penetrating through the base 8 are provided at the top of the base 8. The plurality of positioning rods 1 correspond to the plurality of notches 2 one by one, and the positioning rods 1 are slidably connected to the notches 2 to position the base 8. During the installation of the base 8, through the cooperation between the positioning rods 1 and the notches 2, the base 8 can be positioned, thereby facilitating the installation of the base 8. A fixing ring 10 for supporting the base 8 is welded on the circumferential outer wall of the high-speed motor body 9 below the base 8, thereby reducing the gravity borne by the base 8. A plurality of fixing holes for installing the base 8 are provided on the upper surface of the base 8.

[0024] Working principle: When installing the base 8, the base 8 is sleeved outside the high-speed motor body 9, and the positioning rod 1 enters the notch 2, so as to position and install the base 8. When the installation groove of the base 8 contacts the fixing ring 10, the fixing ring 10 will support the base 8 at this time, thereby reducing the gravity received by the base 8. Then, the magnetic block 12 is pulled to move. The magnetic block 12 will drive the square block 14 to move and disengage from the groove 13. At the same time, the square block 14 will stretch the tension spring 16. At this time, the magnetic block 12 can be used to drive the square block 14 to rotate. The square block 14 will drive the threaded rod 11 to rotate. The threaded rod 11 will move through the thread engagement with the threaded hole. The threaded rod 11 will drive the connecting plate 7 to move horizontally along the base 8. The connecting plate 7 will drive the clamping block 4 to move, so that the clamping block 4 is clamped into the clamping groove 3, thereby connecting the base 8 with the high-speed motor body 9. Then, the magnetic block 12 is released. At this time, under the action of the tension spring 16, the magnetic block 12 will be pulled back to its original position, and the magnetic block 12 will be clamped into the groove 13, thereby fixing the threaded rod 11 and preventing the threaded rod 11 from rotating under the vibration of the motor. Thus, the base 8 can be stably connected to the motor, improving the stability of the connection between the motor and the base 8.
