A drive head (20) of a centrifuge drive for detachably connecting a rotor to the centrifuge. The drive head includes a drive head hub (58) including a plurality of recesses (62) formed in an outer sidewall, a locking shoe (66) movably retained within each of the plurality of recesses to define a hinge joint and pivotable about a hinge axis in a radially inward direction and a radially outward direction, and a resilient element for biasing each locking shoe in the radially inward direction. Each locking shoe is configured to exert a radially outwardly directed force (A2) on an interior sidewall of the hub (22) of the centrifuge rotor to prevent axial movement of the centrifuge rotor along the rotational axis of the centrifuge drive and rotational movement of the centrifuge rotor relative to the drive head, with the radially outwardly directed force increasing with a rising rotational speed of the drive head.

A drive head (20) of a centrifuge drive for detachably connecting a rotor to the centrifuge. The drive head includes a drive head hub (66) including a plurality of recesses (70) formed in an outer sidewall, a locking shoe (74) movably retained within each of the plurality of recesses by the retaining plate (68) so as to be pivotable about a pivot axis in a radially inward direction and a radially outward direction relative to the rotational axis of the centrifuge drive, and a resilient element (92) for biasing each locking shoe in the radially outward direction. Each locking shoe is configured to exert a radially outwardly directed force on an interior sidewall of the hub (22) of the centrifuge rotor to prevent axial movement of the centrifuge rotor along the rotational axis of the centrifuge drive and rotational movement of the centrifuge rotor relative to the drive head, with the radially outwardly directed force increasing with a rising rotational speed of the drive head.

A centrifugal driving apparatus and a centrifugal device are disclosed. The centrifugal driving apparatus includes a first rotating disc, a second rotating disc, a first transmission mechanism, a second transmission mechanism, and a driving mechanism; the driving mechanism drives the second rotating disc to rotate around its own rotation center; the first rotating disc is rotatably disposed on the second rotating disc, and the first rotating disc is connected to the second transmission mechanism by means of the first transmission mechanism; the first transmission mechanism and the second transmission mechanism can switch between a rotating state and a locked state, so that the first rotating disc rotates or is locked around its own rotation center when rotating synchronously with the second rotating disc. The first rotating disc can rotate or be locked when revolving with the second rotating disc.
