[0027] A sliding cavity is provided inside the connecting rod 7, and a counterweight ball 14 is placed inside the sliding cavity; a plurality of springs are fixedly connected between the sliding seat 1 and the sliding frame 2, and the springs are sleeved on the guide rod 11; the elastic force of the springs on both sides of the sliding frame 2 is consistent; during operation, when the sliding frame 2 has finished shaking, the sliding frame 2 is pushed by the spring to restore the sliding frame 2 to its original position, and then the push rod 8 is kept at the bottom position by the pressure of the counterweight ball 14, so that the restoration of the sliding frame 2 can be more accurate, and by resetting the sliding frame 2, the light inside the frosted glass 3 can be more uniform when the irradiation lamp 10 irradiates the frosted glass 3.
