Pop-up device applied to data recording disk box

The invention provides a pop-up device applied to a data recording disk box. The pop-up device comprises a pop-up bottom shell and a cover plate covering the pop-up bottom shell. A strip-shaped grooveis formed in a side plate of the pop-up bottom shell. A spring and a sliding block are arranged in the strip-shaped groove. A cavity is formed in the sliding block. A central bulge is formed in the center in the cavity. The mold cavity consists of a first mold cavity part, a second mold cavity part and a third mold cavity part. The bottom of the second cavity part is of a boss structure higher than the bottom of the first cavity part and the bottom of the third cavity part. The first sliding block splicing part extends towards the cavity to form a vertex angle. A concave part is formed in theposition, opposite to the vertex angle, of the center protrusion, a first guide slope and a second guide slope are arranged at the bottom of the junction, close to the vertex angle, of the upper endof the second cavity part and the upper end of the third cavity part, a clamping hook is further arranged in the cavity, an inserting hole is formed in the third side plate splicing part, and the lower end of the clamping hook is inserted into the inserting hole. The recording disc is simple in overall structure, few accessories are used, and popping-up operation of the recording disc can be achieved more conveniently.
