A clamping device to prevent the plate from being held in place.

Abstract

A clamping device for preventing plate jamming includes a frame, a first support unit, and a first auxiliary support unit. The frame has two clamping arms spaced apart from each other. Each clamping arm has a first side, a second side opposite to the first side, a connecting end and an end portion opposite to the first side, and two third sides connecting the first side and the second side. The first support unit has first support members respectively disposed on the first side of the two clamping arms and spaced apart from the corresponding connecting ends. The first auxiliary support unit is disposed on the two clamping arms and away from the connecting ends, including at least two spaced second support members disposed on the clamping arms, and a first auxiliary support member connected to the second support members and having a first auxiliary support portion. This prevents the substrate from being impacted or squeezed by the plate jamming.
