[0027] The working principle of the utility model is specifically described as follows:

[0031] When a cone with a larger diameter needs to be processed, the distance between the two first movable rollers 402 and the height of the second movable roller 404 can be adjusted by the knob 201. The operator can manually twist the knob 201. When the knob 201 is rotated, the first transmission shaft 202 below it is driven to rotate. When the first transmission shaft 202 is rotated, the first gear 203 connected thereto is driven to rotate. When the first gear 203 is rotated, the second gear 204 meshing therewith is driven to rotate. When the second gear 204 is rotated, the second transmission shaft 205 is driven to rotate. When the second transmission shaft 205 is rotated, the first movable block 206 screwed therewith is driven to move. When the first movable block 206 moves, the first movable roller 402 is driven to move through the first movable rod 401.

[0032] When the first transmission shaft 202 rotates, the second movable block 406 screwed together therewith moves upward. After the second movable block 406 moves upward, it drives the second movable roller 404 to move upward through the second movable rod 403, thereby completing the height adjustment of the second movable roller 404.
