Cutting protection device for sound insulation glass

The cutting protection device comprises a pushing mechanism and a shielding mechanism, the lower end surface of the pushing mechanism is movably connected to the front end of an adjusting mechanism, the inner wall surface of the lower end of the adjusting mechanism is in threaded connection with a glass plate bearing table, and the upper end of the adjusting mechanism is in threaded connection with an electric push rod; the top end surface of a piston rod in the electric push rod is in threaded connection with a motor mounting frame, the inner wall surface of the motor mounting frame is in threaded connection with a cutting motor, a rotor of the cutting motor is in threaded connection with a cutting disc, and the pushing mechanism is movably connected to the upper end of the shielding mechanism. By arranging a glass plate push rod, a metal sliding plate and a glass plate limiting frame, the metal sliding plate and the glass plate push rod push a sound insulation glass plate to move front and back, the cutting
