[0029] like Figure 1-Figure 5As shown, in this embodiment, a first limiting mechanism is further provided on the side where the gimbal 2 and the balancing weight 3 abut. The first limiting mechanism comprises a plurality of first inserting blocks 32 evenly mounted within the groove 31. The first inserting blocks 32 do not extend beyond the groove 31. The convex ring 22 is provided with a plurality of first slots 23 evenly spaced. The first slots 23 are equal in number and positioned correspondingly to the first inserting blocks 32. The first inserting blocks 32 are inserted into the first slots 23. The above components achieve the following effects: the first inserting blocks 32 are equal in number and positioned correspondingly to the first slots 23. When inserted into the first slots 23, the convex ring 22 is prevented from sliding and rotating along the groove 31, thereby maintaining a stable connection between the gimbal 2 and the balancing weight 3. Furthermore, the corresponding position of the first inserting blocks 32 and the first slots 23 ensures that the subsequent through holes 34 can accurately align with the threaded holes 25, facilitating accurate assembly of the gimbal 2 and the balancing weight 3, reducing workload and improving accuracy.

[0030] like Figure 1-Figure 5 As shown, in this embodiment, a second limiting mechanism is further provided on the side where the gimbal 2 and the balancing weight 3 abut each other. The second limiting mechanism includes a plurality of second inserting blocks 24 evenly mounted on the edge of the protruding ring 22.

When inserted into the second slots 33, the second inserting blocks 24 not only prevent the protruding ring 22 from sliding along the groove 31, but also prevent the protruding ring 22 from rotating along the groove 31. This, in conjunction with the first limiting mechanism, maintains the stability of the connection between the gimbal 2 and the balancing weight 3. Furthermore, because the second inserting blocks 24 correspond to the second slots 33, the subsequent through holes 34 can accurately align with the threaded holes 25. This, in conjunction with the first limiting mechanism, facilitates accurate assembly of the gimbal 2 and the balancing weight 3, reducing workload and improving accuracy.

[0031] like Figure 1-Figure 5 As shown, in this embodiment: a sleeve hole 21 is opened in the center of the balance ring 2, and the sleeve hole 21 matches the outer surface of the motor rotor 1; the effect achieved by the above components is: the opening of the sleeve hole 21 allows the balance ring 2 to be sleeved on the outer surface of the motor rotor 1.

[0033] like Figure 1-Figure 5 As shown, in this embodiment: a locking washer 5 is provided between the end of the bolt 4 and the balancing weight 3, and the bolt 4 and the locking washer 5 lock the balancing ring 2 and the balancing weight 3; the effect achieved by the above components is: the bolt 4 is inserted into the threaded hole 25 through the through hole 34, and after being threaded in the threaded hole 25, the end of the bolt 4 squeezes the balancing weight 3 through the locking washer 5, so that the balancing ring 2 and the balancing weight 3 can be locked.

[0034] like Figure 1-Figure 5 As shown, in this embodiment: the threaded end of the bolt 4 is coated with thread locking glue; the effect achieved by the above components is: the threaded end of the bolt 4 is coated with thread locking glue, so that when the bolt 4 is threadedly connected in the threaded hole 25, the connection is tighter.

[0035] The operating principle of the present utility model is as follows: first, the balancing ring 2 is fixed to the outer surface of the motor rotor 1 through the sleeve hole 21, and then the balancing block 3 is installed on the balancing ring 2, so that the convex ring 22 is embedded in the groove 31, and the first plug 32 is embedded in the first slot 23, and the second plug 24 is embedded in the second slot 33.
