Perforating mechanism, grabbing device and glass combining equipment

The embodiment of the utility model provides a perforating mechanism, a grabbing device and glass combining equipment. The through hole structure can be used for assisting the outgoing line to penetrate through the mounting hole of the back plate glass. The perforating mechanism includes: a main body; the supporting frame is connected to the main body; the two clamping pieces are oppositely arranged in a spaced mode, each clamping piece comprises a transmission rod and a clamping plate connected with the transmission rod, the transmission rods are movably connected to the supporting frame, and the transmission rods are used for driving the clamping plates to be switched between the opening state and the closing state; wherein under the condition that the clamping piece enters the mounting hole, the transmission rod drives the clamping plate to move to the opening state under the pressure action of the back plate glass so as to enable the clamping plate to be connected outside the outgoing line in a sleeving m
