When the drag chain body 4 needs to be supported, the frame 3 moves with one end of the drag chain body 4, and the servo motor 52 is turned on at the same time. The servo motor 52 rotates the screw 53, and the screw 53 moves the moving part 54 and the fixed rod, so that the support roller 57 on the bracket 56 moves to the center of the suspended drag chain body 4. The support roller 57 supports the drag chain body 4. The position of the support roller 57 on the bracket 56 is adjusted by the adjusting device 5, so that the support roller 57 is always located below the suspended drag chain body 4. At the same time, the maximum stroke of the drag chain body 4 is increased, and the practicality of the support frame is improved.
[0030] Reference Figure 1-4 As shown, the three support rollers 57 are linearly distributed, and the support rollers 57 fit the bottom of the drag chain body 4. The three support rollers 57 support the suspended part of the drag chain body 4, thereby increasing the support area and thus improving the support effect of the support rollers 57.
