Abstract:
1. An apparatus for testing strength of a corner portion of an object, the apparatus comprising: a support platform; an installation mechanism comprising a slidable plate slidably mounted on the support platform; a force gauge fixed to the slidable plate; a drive mechanism connected to the slidable plate to move the slidable plate and the force gauge; and a push-pull mechanism connected to the force gauge to be pushed or pulled by the force gauge and exerting push or pull force on the corner portion of the object; wherein the push-pull mechanism comprises a stand portion fixed on the platform, a sliding portion mounted to the stand portion and slidable relative to the stand portion, a driving portion attached to the sliding portion to exert force on two sides of the corner portion to urge the two sides to be deformed toward different directions, and a connecting portion connecting the force gauge and the sliding portion; wherein the driving portion comprises a fixing flange extending out from a top thereof; the fixing flange defines a fixing hole; the push-pull mechanism further comprises an adjusting element received in the fixing hole of the fixing flange; and a distal end of the adjusting element abuts the sliding portion to adjust position of the driving portion relative to the sliding portion.
