Abrégé

A conical plastic-shelled bomb includes a plastic shell (1) and an ammunition piece (2) provided in the internal cavity of the plastic shell (1). A firing bore (3) is provided in the bottom (4) of the shell. The plastic shell (1) is a cone structure. The outer diameter of the bottom (4) of the plastic shell (1) is less than that of the top (5) of the plastic shell (1). The shell according to the invention uses cone structure design, such that the plastic-shelled bomb may be put into place very easily, the firing rate of shooting needle can be improved 50%, and the damage of the ammunition piece (2) and unsafe accident can be avoided when the piston cylinder strikes the bomb to its place. Moreover, the ammunition piece (2) which has a raised arc end-surface is loaded in the plastic shell (1) to facilitate the end-surface of the ammunition piece (2) to contact with the bottom of a chamber provided in a nail device, and make the ammunition piece (2) have a more complete combustion and a stronger explosive force, so that the amount of the nitrocellulose can be reduced to further reduce the production cost.
