The inner collar and spindle serve to constrain the compression spring and magnets, and the spindle can also serve to link with the rotating machine.

Preferably, a radial hole is formed in the first fixing block, a locking screw is matched in the radial hole, and the locking screw is fixed in the radial hole in a threaded manner, so that the end part of the locking screw abuts against the fixing sleeve. The fixing sleeve is arranged to rotate relative to the fixing block.

The utility model has the advantages of can fix the axle type work piece, can not make axle type work piece by the clamp wounded.
