A1

A clamp has an unpowered and automatic gripping unit, which includes a first engagement element (10), a drive mechanism (13), and a second engagement element (11). The drive mechanism (13) is connected with a rod (1) and transfers the up/down movement of the rod relative to the supporting base (3) to the first engagement element (10), so as to rotate the first engagement element (10); The second engagement element (11) is provided on said supporting base (3). The first engagement element (10) can rotate between an engagement position and a disengagement position, the first engagement element (10) engages with the second engagement element (11) at the engagement position, the first engagement element (10) disengages with the second engagement element (11) at the disengagement position. Thus, the clamp can realize the clamping action or loosening action when the clamp is raised or lowered, so that realizes the stacking operation for carbon blocks, without the help of the operator standing under the crane. The invention can reduce the hidden safety trouble and improve the work efficiency.
