[0036] A vertical arm 3 is installed on the cross beam 2, and a conical tooth block 31 is provided on the surface of the vertical arm 3. An electric push rod 32 is installed inside the vertical arm 3, and the output end of the electric push rod 32 is connected to a linkage rod 33, and the end of the linkage rod 33 away from the electric push rod 32 is connected to a connecting rod 35, and the end of the connecting rod 35 away from the linkage rod 33 is connected to a valve plate 36, and pins 37 are provided at both ends of the connecting rod 35, and the connecting rod 35 is respectively connected to the valve plate 36 and the linkage rod 33 through the pins 37.

When the first servo motor 14 drives the second gear plate 13 to rotate, the second gear plate 13 can push the main frame 1 to rotate and adjust on the base 12 through the first gear plate 11.

[0038] In this example, an adjustment groove is opened inside the main frame 1, and the driving rod 16 is located in the adjustment groove and is rotatably connected to the main frame 1. The driving rod 16 and the adjustment block 21 are connected by a through-type thread.
