An articulated seat 2 9 is also fixedly provided, and the articulated seat 2 9 is arranged close to the inner wall of the mounting groove 8. An electric push rod 10 is connected between the articulated seat 2 9 and the articulated seat 1 7. Under the telescopic action of the electric push rod 10, the U-shaped frame 4 is driven to swing in the left and right directions, and the guide roller 6 is adjusted to swing in the left and right directions. L-shaped support seats 11 are respectively provided on the front and rear side surfaces of the mounting frame 2 on the right side of the U-shaped frame 4, and the upper and lower ends of the two support seats 11 are also jointly provided with smoothing rollers 15 that can move relative to or opposite to each other.

[0020] A bidirectional screw rod 12 is rotatably provided between the top walls of the two support seats 11 and the top surface of the mounting frame 2. A sliding seat 13 matching therewith is provided at both ends of the bidirectional screw rod 12. A bearing seat 14 is provided at the opposite ends of the two sliding seats 13. A smoothing roller 15 is provided between the two bearing seats 14. A slide groove 22 is provided on the inner side wall of the support seat 11 along its height direction. Two sliding blocks 23 matching therewith are provided in the slide groove 22. The outer ends of the two sliding blocks 23 are fixedly connected to the corresponding end surfaces of the sliding seat 13. The cooperation between the slide groove 22 and the sliding block 23 can increase the stability of the sliding seat 13 during the up and down sliding process. An adjusting device that can control the synchronous rotation of the two bidirectional screw rods 12 is also provided on the bottom wall of the mounting frame 2.

[0021] The adjusting device includes a first bevel gear 17, a second bevel gear 18, a rotating shaft 19 and a double-axis motor 20.
