Firework fixing device

Abstract

The utility model discloses a firework fixing device, which relates to the technical field of firework fixing and comprises a base, an annular support, a lifting mechanism and a fixing mechanism. The inner surface of the base is fixedly connected with a mounting bracket; the lifting mechanism is fixedly arranged at the top of the mounting support and used for adjusting the height of the annular support. According to the utility model, the rotary knob is screwed to drive the transmission rod to rotate, so that the two screw rods in opposite directions are driven to synchronously rotate. Due to the rotation, when the two screw rods rotate, the two guide blocks are dragged to move towards each other or away from each other. When the guide block moves, the first connecting rod is pulled, and meanwhile, in the movement process of the first connecting rod, the second connecting rod plays an auxiliary supporting role to jointly promote the mounting plate to move upwards. And along with ascending of the mounting plate, the annular support achieves ascending and descending actions, the device can meet the position requirement when fireworks are set off in a height adjusting mode, and convenience is brought to operators.
