[0023] As a technical optimization solution of the present invention, the provision of the tooth groove 12 can facilitate the movement of the vertical plate 6 when the gear 3 rotates, and the provision of the stop block 13 can limit the position of the vertical plate 6.

[0024] refer to Figure 4 The surface of the vertical plate 6 is slidably connected with a sleeve 14, and bolts 15 are provided on the front and rear sides of the right side of the sleeve 14. The threaded end of the bolt 15 extends to the left side of the sleeve 14 and is threadedly connected to the right side of the sling 1.

[0025] As a technical optimization solution of the present invention, the position of the vertical plate 6 can be limited by the setting of the sleeve 14 to prevent the vertical plate 6 from detaching from the sling 1, and the sleeve 14 can be prevented from detaching from the sling 1 by the setting of the bolt 15.

[0026] refer to Figure 2 The front side of the surface of the fixed rod 5 is fixedly connected with a bearing 16, the front side of the bearing 16 is fixedly connected to the inner wall of the sling 1, and the left side of the support block 7 is provided with a movable groove 17 for use with the movable rod 11, and the surface of the movable rod 11 is slidably connected to the inner wall of the movable groove 17.

[0027] As a technical optimization solution of the present invention, the position of the fixed rod 5 and the gear 3 can be limited by the setting of the bearing 16 to prevent the fixed rod 5 and the gear 3 from shaking when rotating.

Then the user starts the motor 4, and the output end of the motor 4 drives the gear 3 to rotate counterclockwise. The gear 3 rotates counterclockwise to drive the vertical plate 6 to move upward, so that the vertical plate 6 is disengaged from the groove 19. At this time, the user puts the wind power flange forging on the surface of the fixed rod 5, and then performs the opposite operation to limit the wind power flange forging on the surface of the cross bar 2 through the vertical plate 6, thereby preventing the wind power flange forging from being separated from the sling 1 and the cross bar 2 when the sling 1 moves, thereby increasing the safety of the sling 1.
