The invention relates to a firework battery (10), comprising at least one receiving part (11) for at least one pyrotechnic charge (20) and a border (13), which is connected via at least one hinge part (14) to a further receiving part (11) and/or an extension element (15) that continues the border and that is arranged on a receiving part (11), the axis of rotation of the hinge part being arranged vertically in relation to a ground. According to the invention, it is provided that the geometric arrangements of the receiving part (11) and/or of the extension element (15) are movable relative to one another, whereby a bordered support base (30) of the firework battery (10) is enlarged.

A device for launching fireworks, the device includes: a plastic plug and a locking base. The plastic plug includes: a resistance heating wire, a slot for accommodating the resistance heating wire, two metal conductors, two plate-like electrodes, and an upper clamping structure. The locking base includes: a lower clamping structure, two spring electrodes, and a circuit connecting socket. The top of the plastic plug is provided with the slot for accommodating the resistance heating wire. The resistance heating wire is fixed in the slot for accommodating the resistance heating wire and two ends of the resistance heating wire are electronically connected with one ends of the two metal conductors. The other ends of the two metal conductors are respectively electronically connected with the two plate-like electrodes and fixed at a bottom of the plastic plug. The bottom of the plastic plug is provided with the upper clamping structure.

Disclosed is a kind of combination fireworks, in which a plurality of paper tubes form a tube row, and the plurality of tube rows are stacked and assembled for forming, wherein each tube row is provided with a bottom cardboard, two sides of the bottom cardboard are correspondingly provided with notch positioning holes, and the bottom cardboard beside the notch positioning holes forms the protruding cardboard beside the holes; the cardboard beside the holes is folded and stuck on both sides of the paper tube, and both ends of the paper tube are respectively embedded in corresponding notch positioning holes. The structure of spaced tube rows is adopted, so that the radial size error of the tube body of the paper tube is not accumulated in the tube rows, thus allowing the tube body to accurately reach a predetermined work position, and improving the accuracy and reliability of subsequent processes.

A Cold Spark Device (CSD) is provided and includes a CSD base, wherein the CSD base includes a CSD collector defining a collector cavity, wherein the CSD collector includes a collector top, collector sides and a collector bottom, the collector top defining a top opening, and wherein the collector bottom defines a first collector bottom opening and a second collector bottom opening, a CSD sparkling device, and a CSD display case, wherein the CSD base includes a base structure which defines a base cavity for containing the CSD sparkling device, wherein the base structure defines a base cavity opening communicated with the base cavity.

A modular pyrotechnic launch unit includes a launch module, a first module, and a second module. The launch module includes a launch barrel. The first module is coupled in series to the launch module. The first module includes a first ignition state in which the first module ignites a pyrotechnic element that will then pass through the launch barrel. The first module also includes a first pass-through state in which the first module allows a pyrotechnic element ignited by another module to pass through the first module. The second module is coupled in series to the first module. The second module includes a second ignition state in which the second module ignites a pyrotechnic element that will then pass through the first module and through the launch barrel.
