[0032] Reference Figure 4 The adjustment assembly 10 includes an adjustment seat 11 fixedly connected to the inner wall of the rectangular opening, and the inner walls on both sides of the adjustment seat 11 are rotatably connected to the same bidirectional screw 12. The setting of the adjustment seat 11 facilitates the installation of the bidirectional screw 12.

[0033] Reference Figure 4 The outer wall of the bidirectional screw 12 is screwed with two threaded sleeves 13, and the outer walls of the two threaded sleeves 13 are rotatably connected with connecting plates 15. The threaded sleeves 13 are driven to move by the rotation of the bidirectional screw 12, thereby facilitating the movement of the two connecting plates 15.

[0034] Reference Figure 4 The inner wall of the rectangular opening is slidably connected with a rack 16, and one end of the two connecting plates 15 is rotatably connected to the rack 16, and the rack 16 is conveniently driven to move by moving the connecting plate 15.

[0035] Reference Figure 4 A circular groove is provided on the outer wall of one side of the adjustment seat 11, and a rotating part 14 is rotatably connected to the inner wall of the circular groove. The setting of the rotating part 14 facilitates manual rotation of the bidirectional screw 12, thereby facilitating adjustment of the position of the rack 16.

[0036] Reference Figure 4 One end of the rotating part 14 is fixedly connected to the bidirectional screw 12, and the cross-section of the rotating part 14 is a regular hexagon. The rotating part 14 with a prism structure is convenient for operation with an electric wrench.

[0037] Reference Figure 2 The outer walls on both sides of the wing body 3 are fixedly connected with L-shaped mounting plates 5, and the outer walls on the opposite sides of the two mounting plates 5 are fixedly connected with two sliders 6.
