They can have a flat, corrugated or wavy surface to provide greater sealing ability.

[0039] The working principle of the above embodiment is:

[0040] First, the hob cutter 4 is installed in the installation groove 3 of the installation shaft 2 through the installation seat 501. At this time, the limit seat 503 and the cushion block 504 at the bottom of the installation seat 501 can be tilted and matched to be close to the installation shaft 2.

[0041] Secondly, the threaded rod 506 is driven to move by pulling the mounting block 505, and the threaded rod 506 can cooperate with the threaded groove 5012 to flexibly adjust the height in the fixed cylinder 502, and the threaded rod 506 drives the limit seat 2 507 to move, and the limit seat 2 507 is limited in the sliding groove 509 of the fixed cylinder 502 by the sliding blocks 508 on both sides. When the limiting hole 5010 in the limiting seat 2 507 coincides with the fixing hole 5011 in the fixed cylinder 502, the limiting seat 1 503 is passed through the limiting seat 2 507 by moving the mounting seat 501.

[0042] Finally, after the fixing bolt 5015 penetrates the upper connecting block 5013 and the lower connecting block 5014, and is fixed by the sealing gasket 5016 and the fixing nut 5017, the hob tool 4 is installed on the hob shaft body 1. Therefore, after the hob tool 4 has been used for a long time, the hob tool 4 can be flexibly removed from the hob shaft body 1, thereby enhancing the practicality of the gear edge chamfering hob and other advantages.
