Spring.
By using above-mentioned technical proposal, deep-slotted chip breaker coordinates steel ball to realize the automatic installation of skeleton, is given after installation
Sound and dynamics feedback, it is to avoid skeleton produces vibration in the course of the work.
The utility model is further arranged to：Described buffer board is wholely set with skeleton, described limiting plate periphery with
Skeleton inner circumferential coordinates in screw thread.
By using above-mentioned technical proposal, limiting plate periphery with skeleton inner circumferential in screw thread cooperation, can simple-mounting-dismounting, more
Change buffer spring and seal.
The utility model is further arranged to：Compression is provided with sealant between described skeleton periphery and standing groove.
By using above-mentioned technical proposal, set up sealant and avoid fluid seepage between skeleton and standing groove, strengthen close
