Abstract
A clamping apparatus includes a main shaft, at least two pushing members, a follow member movably sleeved on the main shaft, a coupling member fixedly sleeved on the main shaft, at least two first linkages respectively pivoted to the follow member, at least two second linkages, and a nut. Each of the at least two second linkage is pivoted to the corresponding first linkage, the coupling member, and the corresponding pushing member. The nut is movably sleeved on the main shaft and positioned at a side of the follow member away from the coupling member. The nut is configured to move the follow member towards the coupling member, to enable the at least two pushing members to move away from the main shaft.
