Detailed Description
The shaft for conversion shown in fig. 1 or 2 includes a shaft mounting base 100, and a first shaft mounting mechanism 200 is provided on the shaft mounting base 100. The first shaft mounting mechanism 200 includes first to third annular portions 210, 220, and 230 that are provided in steps.
A first shaft installation groove 211 is formed in the first annular part 210, a second shaft installation groove 221 is formed in the second annular part 220 and the third annular part 230, and the diameters of the first to third annular parts 210, 220 and 230 are gradually reduced; the ratio of the diameters between the first to third annular portions 210, 220, and 230 is 17: 29: 35. the top directions of the first shaft mounting groove 211 and the second shaft mounting groove 221 are oppositely arranged;
on one side of shaft mount 100 is provided second shaft mount mechanism 300, second shaft mount mechanism 300 being in the opposite direction of first shaft mount mechanism 200, second shaft mount mechanism 300 including fourth annular portion 310 and fifth annular portion 320, third shaft mount slot 311 being provided in fourth annular portion 310 and fifth annular portion 320. The diameter of the fourth annular portion 310 is greater than the diameter of the fifth annular portion 320.
The direction of the third shaft mounting groove 311 is the same as that of the second shaft mounting groove 221. In addition, the shaft mounting base 100 is provided with a mounting hole 101.
The notches of the first shaft mounting groove 211, the second shaft mounting groove 221 and the third shaft mounting groove 311 are provided with chamfers having an angle of 45 °.
Due to the structure, the utility model can lock the vibration pressing wheel through the slow rotating shaft to achieve the effect of no back pressure when the packing paper is replaced;
and after the sharp corner of the lock block is rotated to push the lock block to leave the notch, the self-locking function is released, and the vibration pressure function is recovered.
