[0030] Secondly, the plurality of support components are respectively arranged between the fixing sleeve 125 and the mounting block 103. The fixing sleeve 125 is fixedly connected to the adjusting rod 106 and is sleeved on the end of the adjusting rod 106 away from the rotating ring 121. The arrangement of the support component and the fixing sleeve 125 can facilitate the improvement of the stability of the adjusting rod 106 during movement, thereby improving the service life of the adjusting rod 106 and the fixing tube 105.

[0032] When the utility model is used to adjust the horizontal position of the ranging roller, the rotating disk 117 is rotated to drive the screw 118 to rotate, and the screw 118 rotates under the action of the rotating ring 121. At the same time, the adjusting rod 106 is slowly moved out of the fixed tube 105 under the action of the thread groove 124, so that the adjusting rod 106 drives the ranging roller 114 to move horizontally, and the stability of the adjusting rod 106 when moving can be improved by setting the supporting rod 126 and the supporting tube 127, thereby improving the service life of the adjusting rod 106 and the fixed tube 105. In this way, the problem that the lateral support rod 126 uses a telescopic rod to support the ranging roller 114 is solved, and the telescopic rod in the above scheme is fixed by a pin to the telescopic length, so as to complete the adjustment of the telescopic rod.
