An over-loading protection pressing device adapted for pressing an object includes a housing, a pressing head and a protection portion. The housing has a clamping portion fixed thereon. The pressing head protrudes from the housing, and the pressing head is configured for pressing the object. The protection portion is configured to be received in the housing and coupled to the pressing head via a supporting pole. The protection portion is clamped by the clamping portion. When a pressure along a lengthwise direction of the housing is in a predetermined range, the clamping portion is clipped on a first position of the protection portion; when the pressure is over a predetermined range, the clamping portion can move from the first position to a second position.
