The chamfer 17 facilitates the side baffle 16 to be inserted into the slot 14.

[0021] The working principle of this utility model is as follows: During disassembly, the nut on the fixing screw 15 is removed, and then the threaded rod 8 is rotated. The threaded rod 8, through the threaded engagement with the threaded hole, pushes the inner bracket 6 upward. The inner bracket 6 moves vertically upward under the action of the guide rod 7. During the movement of the inner bracket 6, it pushes the connecting shaft 5 upward. The connecting shaft 5 drives the roller frame 4 and the side fixing shaft 11 upward. The side fixing shaft 11 drives the left bracket 1 and the right bracket 2 upward, causing the left bracket 1 and the right bracket 2 to move out of the positioning stop 18 and disengage the side baffle 16 from the slot 14. At the same time, the fixing screw 15 disengages from the oval hole 13. Then... Remove the left bracket 1 and right bracket 2, and simultaneously remove the pressure sleeve 10. Then, the roller frame 4 can be removed for maintenance. After maintenance, reset the inner bracket 6, insert the side fixing shaft 11 into the support bearing 12 on the left bracket 1 and right bracket 2, insert the left bracket 1 and right bracket 2 into the positioning bracket 18, and let the fixing screw 15 pass through the oval hole 13. Then, let the side baffle 16 be inserted into the slot 14 to position the left bracket 1 and right bracket 2, thereby positioning and installing the roller frame 4. Then, fix the roller frame 4. This allows for positioning and installation after the roller frame 4 has been disassembled and maintained, which is convenient for disassembling and maintaining the roller frame 4, saves time, and improves efficiency.
