[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention.

[0019] Hereinafter, a high-charge fireworks safety device according to an embodiment of the present invention will be described with reference to the accompanying drawings. Figures 1 to 6As shown, the high-charge fireworks safety ignition device includes a base 1 and a first splint 2 and a second splint 3 arranged on the base 1. A plurality of slide grooves 101 are opened on the base 1, and the slide grooves 101 are arranged equidistantly around. A first protrusion 201 is provided at the center of the bottom of the first splint 2, and a second protrusion 301 is provided at the center of the bottom of the second splint 3. The first protrusion 201 and the second protrusion 301 are respectively slidably installed in the plurality of slide grooves 101. An adjustment component is also provided at the bottom of the base 1 for adjusting the distance between the first splint 2 and the second splint 3.

[0020] Preferably, the number of the first clamping plates 2 and the number of the second clamping plates 3 are both two, and they are symmetrically arranged.

[0021] Preferably, the adjustment assembly includes a first boss 202, a second boss 302, a disc 4, a connecting rod 5 and a screw 6, the first boss 202 is fixedly mounted on the bottom of the first boss 201, the second boss 302 is fixedly mounted on the bottom of the second boss 301, the disc 4 is rotatably mounted at the bottom center of the base 1 through a bearing, and the connecting rod 5 is bent, wherein a support rod is integrally formed on the top of the disc 4, a bearing is nested on the support rod of the main gear 3, and the bearing is fixed to the bottom of the base 1.

[0022] Preferably, a screw hole 203 is provided on the first boss 202, and connecting seats 102 are symmetrically provided on both sides of the base 1. The screw 6 is rotatably installed on the two connecting seats 102 through a bearing. The screw 6 is threadedly connected to the screw hole 203 on the first boss 202. A knob 601 is provided at one end of the screw 6, and the surface of the knob 601 is provided with anti-slip grooves. By providing anti-slip grooves on the surface of the knob 601, it is easy to rotate the knob 601.

[0023] In a specific embodiment: bidirectional threads are symmetrically provided on the screw 6, and the screw 6 is threadedly connected to the screw holes 203 on the two first bosses 202. When the screw 6 rotates, it will drive the two first bosses 202 to move closer to or away from each other, thereby driving the first protrusion 201 on the top of the first boss 202 to move closer to or away from each other in the slide groove 101, and the first protrusion 201 drives the first splint 2 to move synchronously.

[0024] Preferably, a first support 7 is provided on the side walls of the first boss 202 and the second boss 302, four second supports 8 are equidistantly provided on the side wall of the disc 4, and there are two connecting rods 5, one end of the connecting rod 5 is hinged to the first support 7, and the other end of the connecting rod 5 is hinged to the second support 8.

[0025] In a specific embodiment, when the box for placing fireworks needs to be fixed, the screw 6 is driven to rotate by rotating the knob 601. Since the screw 6 is symmetrically provided with a bidirectional thread, the screw 6 will drive the two first bosses 202 connected thereto to move closer to each other when the screw 6 rotates. The first boss 202 will synchronously drive the first splint 2 to move closer to each other through the setting of the first boss 201. At the same time, since the side wall of the first boss 202 is provided with a first support 7, one end of the connecting rod 5 is hinged to the first support 7, and the other end is hinged to the side wall of the disc 2. The second support 8 is hinged, and when the first boss 202 moves, the disk 4 is driven to rotate through the transmission of the connecting rod 5. When the disk 4 rotates, the second boss 302 is driven to move closer to each other through the transmission of the connecting rod 5. The second boss 302 drives the second clamping plate 3 to move closer to each other synchronously. The box for placing the fireworks is fixed by two sets of first clamping plates 2 and second clamping plates 3 that are close to each other, so that the impact force generated during the firing process will not cause the fireworks to tilt, so that the fireworks can be fired more safely and with higher safety.

[0026] Working principle: When in use, place the launch tube for setting off fireworks on the base 1, and then turn the knob 601 to drive the screw 6 to rotate. Since the screw 6 is symmetrically provided with a bidirectional thread, when the screw 6 rotates, it will drive the two first bosses 202 connected with it to move closer to each other. The first boss 202 will synchronously drive the first splint 2 to move closer to each other through the setting of the first boss 201. At the same time, since the side wall of the first boss 202 is provided with a first support 7, one end of the connecting rod 5 is hinged to the first support 7, and the other end is hinged to the side wall of the disc 2. The second support 8 on the upper part is hinged. When the first boss 202 moves, the disk 4 is driven to rotate through the transmission of the connecting rod 5. When the disk 4 rotates, the second boss 302 is driven to move closer to each other through the transmission of the connecting rod 5. The second boss 302 drives the second clamping plate 3 to move closer to each other synchronously. The launch tube for firing the fireworks is fixed by the two sets of first clamping plates 2 and second clamping plates 3 that are close to each other, so that the launch tube will not tilt due to the impact force generated by the fireworks during the firing process, so that the fireworks can be fired more safely and with higher safety.
