Referring to fig. 1, 2 and 3, a multifunctional firework setting off device comprises a base 1 and balancing weights 19 fixedly connected to two sides of the base 1 and used for increasing the weight of the base 1, so that the base 1 is more stable. The base 1 both sides fixedly connected with mounting bracket 2 is equipped with support 3 between the mounting bracket 2, sets up the hole 4 of placing that a plurality of linear array set up on the support 3 for place the fireworks of waiting to set off. The support 3 is located and places 4 below sliding connection of hole and have backup pad 5, and backup pad 5 supports the fireworks bottom of placing in the hole 4. The equal fixedly connected with pivot 6 in support 3 both sides, pivot 6 are located support 3 both sides middle part position, and 6 levels in two pivots set up and the axis coincidence, and two pivots 6 rotate with two mounting brackets 2 respectively and are connected. One of them pivot 6 passes mounting bracket 2 fixedly connected with worm wheel 7, and one side fixedly connected with mount pad 8 that mounting bracket 2 is close to worm wheel 7 rotates on the mount pad 8 and is connected with drive shaft 9, and 9 one end fixedly connected with worms 10 of drive shaft, worm 10 and the meshing of worm wheel 7, and worm 10 rotates can drive worm wheel 7 and rotate.

This multi-functional fireworks setting off device can drive worm 10 when rotating drive shaft 9 and rotate, and worm 10 rotates worm wheel 7 and rotates, and worm wheel 7 rotates and drives pivot 6 simultaneously and rotates to make support 3 revolute 6 rotations of pivot, and then the change is located support 3 and places the fireworks angle in hole 4.

Referring to fig. 1, 2, 3, the one end that worm 10 was kept away from to drive shaft 9 passes mount pad 8 fixedly connected with driving-disc 11, and driving-disc 11 can drive shaft 9 and rotate when rotating, and one side fixedly connected with drive handle 12 that driving-disc 11 kept away from drive shaft 9, and drive handle 12 is located eccentric settings on driving-disc 11, can drive driving-disc 11 through rotating drive handle 12 and rotate to make drive shaft 9 rotate.

Spacing groove 13 has been seted up to support 3 and is located 5 both sides of backup pad, the vertical setting of

spacing groove

13, 5 both ends of backup pad stretch into spacing inslot 13 with support 3 sliding connection, carry on spacingly to backup pad 5 through spacing groove 13 for backup pad 5 reciprocates along spacing groove 13. The supporting plate 5 is rotatably connected with a threaded rod 14 which is vertically arranged, one end, far away from the supporting plate 5, of the threaded rod 14 penetrates through the support 3 and is in threaded connection with the support 3, and the threaded rod 14 can drive the supporting plate 5 to move up and down when rotating, so that the bottoms of fireworks with different lengths are supported.

Referring to fig. 1, fig. 3, fig. 4, support 3 is located and places the downthehole fixture that is equipped with of hole 4, fixture includes two relative clamp splice 15 that set up, two clamp splice 15 are located same horizontal plane, holding tank 16 has all been seted up to support 3 both sides in being located and placing hole 4, two clamp splice 15 are located respectively in two holding tank 16 with support 3 sliding connection, be equipped with reset spring 17 between clamp splice 15 and the support 3, reset spring 17 drives two clamp splice 15 and is close to each other and carry out the centre gripping fixed to the fireworks that lie in between two clamp splice 15, shake when reducing fireworks and setting off.

Accommodating groove 16 is T shape, and clamp splice 15 is close to reset spring 17's one end both sides fixedly connected with stopper 18, and stopper 18 is located accommodating groove 16 and support 3 sliding connection. When clamp splice 15 stretches out holding tank 16 certain distance, stopper 8 is contradicted with support 3, and stopper 18 is spacing clamp splice 15, avoids clamp splice 15 to be popped out holding tank 16 by reset spring 17. Two 15 adjacent sides of clamp splice all are equipped with the silica gel cushion, and the silica gel cushion can reduce the damage that clamp splice 15 caused fireworks outside when carrying out the centre gripping to fireworks.

The working principle is as follows: during the use, remove through rotating 14 drive backup pad 5 threaded rod, make backup pad 5 adjust to suitable height, the fireworks bottom of putting off is conveniently supported, the fireworks that will wait to set off are inserted and are placed in the hole 4 again, it can carry out the centre gripping to fireworks to be located two clamp splices 15 of placing in the hole 4 and fix, reduce the shake of fireworks in-process of putting off, then required angle when setting off according to fireworks, rotation drive handle 12 drives drive shaft 9 and rotates, thereby make worm 10 drive worm wheel 7 rotate, and then make pivot 6 drive support 3 rotate, stop rotating drive handle 12 after adjusting suitable angle, 7 worms on the worm wheel 10 realize the auto-lock, thereby make the setting off device angle fixation, effect when suggestion fireworks are set off.

The above, only be the embodiment of the preferred of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, which are designed to be replaced or changed equally, all should be covered within the protection scope of the present invention.
