[0022] Among them, a sliding groove 2 is opened at the upper end of the base 1, and a threaded rod 3 is rotatably connected between the inner walls on the left and right sides of the sliding groove 2. Both threaded ends of the threaded rod 3 are threadedly connected with a slider 4, the slider 4 is fixedly connected to the moving bar 6, the slider 4 is slidably connected to the inner wall of the sliding groove 2, the upper end of the slider 4 passes through the sliding groove 2 and is fixedly connected to the lower end of the moving bar 6, and a driving motor 5 is installed on the left side of the base 1. The output shaft of the driving motor 5 extends into the sliding groove 2 and is fixedly connected to the left end of the threaded rod 3. The driving motor 5 is a servo motor that can change the rotation direction.

[0023] Among them, it also includes a second limiting mechanism, which is used to limit the motor base. The second limiting mechanism includes a vertical plate 8 connected to the upper end of the base 1, and a support plate 9 is fixedly connected to the left side of the vertical plate 8. The central axis of the support plate 9 and the central axis of the mounting column 7 are in the same position. Two second slide grooves 14 are symmetrically opened on the left side of the support plate 9, and the inner bottoms of the two second slide grooves 14 are both installed with second electric telescopic rods 15. The telescopic ends of the two second electric telescopic rods 15 are both fixedly connected with second arc-shaped abutments 16, and the opposite sides of the two first arc-shaped abutments 12 are both fixedly connected with support plates 13.

[0024] In the utility model, when it is used, the staff first passes the motor winding through the mounting column 7, and then starts the two first electric telescopic rods 11, so that the two first arc-shaped bars 12 are extended synchronously and support the inner side of the motor winding, and then passes the two second arc-shaped bars 16 through the right side of the motor base, and starts the two second electric telescopic rods 15 to extend, so that the two second arc-shaped bars 16 move back to back and support the inner side of the motor base, the right side of the motor base contacts the right side of the support plate 9, and the left side of the motor winding contacts the two support plates 13;
