Strength testing device for glass production

The invention discloses a strength testing device for glass production. The strength testing device comprises a second shell, an impact mechanism, a protection mechanism and a clamping mechanism, wherein the impact mechanism is used for fixing and releasing a metal impact ball, the impact mechanism comprises a cylinder body and an electric push rod, and the electric push rod is installed at the top of the inner side of the cylinder body; wherein the protection mechanism is used for preventing glass fragments from splashing, and the protection mechanism comprises a cover plate and a baffle plate; wherein the clamping mechanism is used for fixing to-be-tested glass at a test position. During use, the electromagnet is arranged to be matched with the inclined hole plate to fix the metal impact ball, after release, the baffle is matched with the cover plate and the second shell to limit splashing of glass fragments, and damage to testers caused by splashing of the fragments is prevented; in addition, the manual re
