Perforating device applied to plastic shells

The invention discloses a perforating device applied to plastic shells. The perforating device applied to the plastic shells comprises a horizontal strip-shaped support plate, wherein an inverted T-shaped support seat is fixed to one end of the support plate; a stand column is hinged to the other end of the support plate; a vertical double-screw bolt is formed at the upper end of the stand column;a vertical plate is arranged at the position, close to the stand column, of the support plate; a vertical inserting rod is formed at the lower end of the vertical plate and is inserted onto the support plate; a horizontal first support plate is formed on a side wall of the vertical plate; an adjusting bolt is in screw joint onto the support plate on the lower side of the first support plate; a support pillar is formed at the upper end of the adjusting bolt, and penetrates through the first support so as to be fixedly inserted and sleeved by a limiting sleeve; the limiting sleeve is abutted against the upper end surface of the first support plate; an L-shaped second support plate is formed at the upper end of the vertical plate; and two horizontal pressing rods are fixed onto two side walls of the second support plate and are distributed right above the support seat. According to the perforating device applied to the plastic shells provided by the invention, perforated parts on the plastic shells can be supported, the possibility of the damage of the plastic shells during perforating can be reduced, and the generation of scraps is reduced.
