Description

Technical Field

[0001] The utility model relates to the field of fireworks manufacturing and design, in particular to a fireworks setting device. Background Art

[0002] With the development of economy and the improvement of people's living standards, people's requirements for quality of life are getting higher and higher. Among the current fireworks products, small rotating fireworks have a single way of playing, the design of the fireworks setting device is relatively simple, and the fireworks effects that can be presented are relatively single, lacking innovation and diversity, which makes it difficult to meet people's growing aesthetic needs for fireworks performances, and also makes people unable to experience the fun of setting off fireworks, and the experience is bad. At the same time, because some fireworks are set off close to the human body, it is very easy to burn the human body, resulting in serious casualties and property losses. Utility Model Content

[0003] Based on this, it is necessary to provide a fireworks setting device to address the problems that the fireworks have a relatively single effect and are close to the human body when set off.

[0004] A fireworks setting device, comprising: a pull rope assembly; a rotating assembly, wherein the rotating assembly is provided with an axle accommodating hole, the rotating assembly is arranged on the pull rope assembly, a portion of the pull rope assembly is located at the axle accommodating hole and the pull rope assembly is passed through the rotating assembly; and a fireworks placing assembly, wherein the fireworks placing assembly is arranged on the rotating assembly.

[0005] The present application discloses a fireworks ignition device, wherein a rotating assembly is arranged on a pull rope assembly, and the pull rope assembly is located at a shaft body receiving hole provided on the rotating assembly, and the shaft body receiving hole can limit the moving range of the rotating assembly, prevent it from excessive shaking or deviation during the process of launching and rotating the fireworks, effectively ensure that the rotating assembly can stably rotate, help maintain the stability of the overall structure of the fireworks, reduce the occurrence of accidents caused by loose or unstable components, and improve the safety and reliability of the fireworks. At the same time, the cooperation between the shaft body receiving hole and the pull rope assembly can form a relatively tight connection, and this connection method can increase the contact area between the rotating assembly and the pull rope assembly, improve the strength and firmness of the connection, and can withstand greater centrifugal force and tension when the fireworks are launched and rotated, prevent the rotating assembly from separating from the pull rope assembly, and ensure the normal operation of the fireworks. Moreover, the rotating assembly is arranged on the pull rope assembly and connected using the shaft body receiving hole, which can make the assembly of the fireworks more convenient and quick, reduce the number and complexity of parts, reduce the difficulty of assembly, and improve production efficiency. Placing the fireworks placement assembly on the rotating assembly can ensure that the fireworks rotate with the rotating assembly, presenting a more colorful and dynamically changing fireworks show to the audience, increasing the viewing and interest of the fireworks. Moreover, through rotation, the light of the fireworks can be displayed at different angles and directions, expanding the visible range of the fireworks and allowing more people to appreciate the beauty of the fireworks.

[0006] In one embodiment, the pull rope assembly includes a rope and an assembly shaft, the rope is arranged on the assembly shaft, and the assembly shaft is arranged on the rotating assembly and located at the shaft receiving hole. By arranging the rope on the assembly shaft, and arranging the assembly shaft on the shaft receiving hole of the rotating assembly, the assembly shaft serves as an intermediate component connecting the rope and the rotating assembly, and plays the role of assembly and connection. The user can stand at both ends of the pull rope assembly and grab the pull rope assembly, and then ignite the fireworks placed on the rotating assembly. The fireworks generate a driving force to drive the rotating assembly to rotate, adding a dynamic element to the fireworks show.

[0007] In one embodiment, the assembly shaft body includes a first half shaft body and a second half shaft body. The first half shaft body and the second half shaft body cooperate with each other. The first half shaft body is provided with a first mating groove, and the second half shaft body is provided with a second mating groove. A part of the first half shaft body is clamped at the second mating groove, and a part of the second half shaft body is clamped at the first mating groove. By respectively arranging the first half shaft body and the second half shaft body in the second mating groove and the first mating groove, and matching the first half shaft body and the second half shaft body with each other and locating them in the corresponding mating grooves, the matching of the first mating groove and the second mating groove can help ensure that the second half shaft body and the first half shaft body have a high concentricity after assembly, which is crucial for the normal operation of the rotating assembly. Because if the two half shaft bodies are not concentric, it will lead to rotational imbalance, increased vibration and even damage to other components. Through the precise design of the mating grooves, the two half shaft bodies can be kept on the same axis as much as possible after assembly, thus ensuring the smoothness and precision of rotation. The mating grooves can also play a positioning role to ensure that the two half shaft bodies can be correctly aligned during installation, avoiding installation errors. At the same time, the mating grooves can also provide additional contact areas and connection points, thereby enhancing the connection strength between the two half shaft bodies, helping to ensure that the two half shaft bodies will not easily separate or loosen under the action of high-speed rotation and various forces of the rotating assembly, and can effectively and firmly clamp the rope, improving the stability and reliability of the entire structure.

[0008] In one embodiment, the rotating assembly includes a shaft matching column, a chassis, a support block, a rotating plate and a stop block. The pull rope assembly is arranged on the shaft matching column, the shaft matching column is arranged on the chassis, the shaft matching column is provided with the shaft accommodating hole, the chassis is provided with a wire groove, the rotating assembly is assembled with the pull rope assembly through the wire groove, the number of the support blocks is multiple, and the multiple support blocks are arranged around the shaft matching column, the number of the rotating plates is multiple, and the multiple rotating plates are arranged along the chassis, and the multiple rotating plates are connected to the fireworks placement assembly, the stop block is arranged on the shaft matching column and is located in the shaft accommodating hole, the assembly shaft is provided with an installation groove, and the stop block cooperates with the installation groove. By arranging the pull rope assembly on the shaft body matching column, and arranging the shaft body matching column on the chassis, the chassis, as the structural foundation of the rotating assembly, has a large area and weight, and can provide stable support for the shaft body matching column. The shaft body matching column is installed on the chassis, and multiple support blocks are arranged around the shaft body matching column, and multiple rotating plates are arranged along the circumference of the chassis and connect the fireworks placement assembly, which can ensure that the fireworks remain vertical and stable during the rotation process. Since the stop block cooperates with the installation groove, the rotating assembly will not shake, tilt or fall easily. At the same time, the pull rope assembly is arranged on the shaft body matching column, and the stability of the shaft body matching column can also be used to ensure that the pull rope assembly will not shake significantly during the pulling process, so that the rotation start of the fireworks is more stable and reliable. This structure helps to enhance the strength of the fireworks launching device. The shaft body mating column connects the chassis and the pull rope assembly, which plays a role in transmitting force and enhancing structural strength. When the pull rope assembly is pulled, the generated tension is transmitted to the shaft body mating column through the pull rope assembly, and then transmitted to the chassis by the shaft body mating column. The chassis can withstand a large force, thereby dispersing and bearing the tension generated by the pull rope assembly, avoiding local excessive force and causing structural damage.

[0009] In one embodiment, the shaft body matching column includes a main column and a secondary column, the main column and the secondary column are both arranged on the chassis, the main column and the secondary column are arranged opposite to each other, a plurality of support blocks are arranged around the main column and the secondary column, and the main column and the secondary column are enclosed to form the shaft body receiving hole. By arranging the main column and the secondary column on the chassis, the chassis can provide a stable basic support for the main column and the secondary column above, which can ensure that the entire structure can remain stable under various circumstances and is not easy to tip over or shake, and the main column and the secondary column are erected from the chassis to form a relatively stable three-dimensional structure, thereby enhancing the overall anti-interference ability. Arranging multiple support blocks around the main column and the auxiliary column can provide additional support for the main column and the auxiliary column. When the fireworks device is subjected to various external forces during use, such as wind force, the recoil force of the fireworks launch, etc., the support blocks can share part of the pressure to prevent the main column and the auxiliary column from tilting or deforming, thereby enhancing the stability of the entire structure. At the same time, multiple support blocks are arranged around to provide support from different directions, so that the main column and the auxiliary column can be well supported in all directions, further improving the stability of the structure. The shaft accommodating hole formed by the main column and the auxiliary column allows the pull rope assembly to be stably placed therein, providing basic support for the normal operation of the fireworks firing device. The shaft can rotate freely in the hole to achieve the rotating effect of the fireworks.

[0010] In one embodiment, the fireworks placement assembly includes a top shell, a rear shell and a connecting plate, the top shell and the rear shell are both arranged on the rotating assembly, and the connecting plate is arranged on the rotating assembly and connects the top shell and the rear shell respectively. By arranging the top shell and the rear shell on the rotating assembly, the top shell and the rear shell are combined with the rotating assembly to form a relatively stable overall structure, providing a stable installation platform for fireworks. By arranging the fireworks between the top shell and the rear shell, the position of the fireworks can be effectively fixed to prevent them from shaking or shifting during the rotation process, which helps to ensure that the fireworks can be launched according to the predetermined trajectory and direction, improve the effect and quality of the fireworks performance, and the stable installation can also reduce the possibility of accidents during the launch of fireworks, such as fireworks falling, tilting or deviating from the target. The connecting plate is arranged on the rotating assembly and the top shell and the rear shell are connected to form a more stable frame structure. This frame can provide a stable placement space for fireworks to prevent fireworks from large displacement in all directions. The fireworks are wrapped in this frame and supported and restricted from different directions, thereby enhancing the fixing effect of the fireworks. When the rotating assembly rotates, the frame structure can withstand external forces such as centrifugal force to ensure that the fireworks will not loosen or fall off due to rotation.

[0011] In one embodiment, the fireworks placement assembly further includes a stopper and a stopper, wherein the stopper is arranged on the rotating assembly, the stopper is arranged opposite to the rear shell, the rear shell is provided with a receiving groove, and the stopper is arranged on the rotating assembly and is located in the receiving groove. By arranging the stopper behind the rear shell, the user can easily place the fireworks in the receiving groove by using the elastic force of the stopper, and can effectively prevent the fireworks from moving backwards during rotation, ensuring that the fireworks are always in the correct installation position, and ensuring that the direction and angle of the fireworks are accurate. By limiting the backward movement of the fireworks, it helps to maintain the stable position of the fireworks in the entire fireworks placement assembly, which is crucial to achieving the expected effect of the fireworks, because the stable position can ensure that the combustion and explosion process of the fireworks is carried out according to the design, avoiding unexpected situations caused by position changes, such as the fireworks deviating from the predetermined orbit, affecting the launch of other fireworks, etc. If the fireworks move backwards too much during the rotation process, they may fall off the rotating assembly, causing safety hazards. The existence of the stopper can greatly reduce this risk, ensuring that the fireworks are always kept in a safe position during the entire use process, protecting the safety of surrounding people and property. At the same time, the blocking block is set on the rotating component and located in the receiving groove. The elastic force of the blocking block can be used to further limit the movement of the fireworks from the side and other directions, realizing all-round restriction. This can ensure that the fireworks are effectively fixed in all directions, greatly enhancing the stability of the fireworks position. Compared with the traditional method of using glue to stick the fireworks to limit the position, this method of limiting the position using the elastic force of the limiting block and the blocking block is more secure and safer. Since the top of the blocking block is facing the position where the fireworks are pushed into the installation, it is easier and smoother to put the fireworks into the receiving groove, increasing the convenience of the installation operation.

[0012] In one embodiment, the positioning block includes a fixed seat and a top block, the fixed seat is arranged on the rotating assembly, the top block is arranged on the fixed seat, and the top block is used to fix the position of the fireworks. By correspondingly arranging multiple top blocks on multiple fixed seats, the combination of multiple top blocks and fixed seats can fix the fireworks at multiple positions, and can also help maintain the launch angle of the fireworks. During the launch of fireworks, due to the influence of recoil and other factors, the fireworks may change their angle. The fixing effect of the top block can reduce such angle changes and ensure that the fireworks always maintain a stable angle during the launch process, thereby improving the accuracy and reliability of the fireworks launch. If the fireworks are not well fixed, these forces may cause the fireworks to shake in the rotating structure or even fall off. The presence of the top block can increase the friction and support force between the fireworks and the rotating assembly, reduce the shaking of the fireworks, thereby enhancing the stability of the fireworks firing device. The presence of the top block can greatly reduce the serious damage to the surrounding personnel and equipment, and improve the safety of the fireworks performance.

[0013] In one embodiment, the number of the fireworks placement components is multiple. By setting the number of fireworks placement components to multiple, the fireworks setting device can store multiple fireworks, producing more colorful, spectacular and shocking visual effects. Fireworks of different colors, shapes and effects bloom at the same time, which can attract the audience's attention and enhance the viewing and fun of the fireworks show. In addition, multiple fireworks blooming at different positions can create a rich layered picture and create a dynamically changing visual effect, so that the audience can feel a richer visual experience.

[0014] In one embodiment, it also includes a handle assembly, the number of which is two, and the two handle assemblies are arranged at both ends of the pull rope assembly, and the handle assembly is provided with a matching hole, and the pull rope assembly is adapted to the matching hole. By arranging two handle assemblies at both ends of the pull rope assembly, and the pull rope assembly is located at the matching hole provided in the handle assembly, firstly, the handle assembly provides a convenient gripping position, so that the operator can more easily grasp the pull rope assembly, and the handle design at both ends makes the operation on both sides more comfortable and stable, and it is convenient to pull the pull rope with force. Secondly, the existence of the handle assembly allows the operator to better control the strength of the pull rope. By holding the handle assembly, the pulling amplitude of the pull rope can be more accurately adjusted, thereby more accurately controlling the start-up and operation of the fireworks firing device. The pull rope assembly is located at the matching hole, and the handle assembly can play a role in fixing the pull rope position, which can prevent the pull rope from sliding or shifting during use, and ensure that the pull rope is always in the correct position, so as to effectively transmit power and control the fireworks firing device.

[0015] In one embodiment, the handle assembly includes a handle shell and a matching piece, the handle shell is correspondingly arranged on the matching piece, the matching piece is arranged on the pull rope assembly and located at the end of the pull rope assembly, the handle shell is provided with a placement hole, and the matching piece is provided with the matching hole. By arranging the handle shell on the matching piece, and arranging the matching piece at both ends of the pull rope assembly, since the handle shell is provided with the placement holes, an ergonomic gripping position is provided for the operator. Compared with directly holding the pull rope assembly, the shape and material of the placement holes can better adapt to the shape of the hand, provide a more comfortable gripping feeling, and reduce hand fatigue. The matching hole provided in the matching piece provides a fixed position for the pull rope assembly. When assembling, the rope of the pull rope assembly is stretched and knotted, and then placed in the matching hole, which can effectively prevent the pull rope assembly from sliding or shifting at will during use, thereby ensuring the safety of the fireworks setting device during use.

[0027] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0029] The fireworks setting off devices according to some embodiments of the present invention will be described below with reference to the accompanying drawings.

[0030] Example

[0031] like Figures 1 to 6As shown, this embodiment discloses a fireworks setting device, including: a pull rope assembly 1; a rotating assembly 2, the rotating assembly 2 is provided with an axle accommodating hole 201, the rotating assembly 2 is arranged on the pull rope assembly 1, a part of the pull rope assembly 1 is located at the axle accommodating hole 201 and the pull rope assembly 1 is passed through the rotating assembly 2; a fireworks placing assembly 3, the fireworks placing assembly 3 is arranged on the rotating assembly 2.

[0032] The present application discloses a fireworks ignition device, wherein a rotating assembly 2 is arranged on a pull rope assembly 1, and the pull rope assembly 1 is located at a shaft body receiving hole 201 provided on the rotating assembly 2, and the shaft body receiving hole 201 can limit the movement range of the rotating assembly 2, prevent it from excessive shaking or deviation during the fireworks launch and rotation process, effectively ensure that the rotating assembly 2 can stably rotate, help maintain the stability of the overall structure of the fireworks, reduce the occurrence of accidents caused by loose or unstable components, and improve the safety and reliability of the fireworks. At the same time, the cooperation between the shaft body receiving hole 201 and the pull rope assembly 1 can form a relatively tight connection, and this connection method can increase the contact area between the rotating assembly 2 and the pull rope assembly 1, improve the strength and firmness of the connection, and can withstand greater centrifugal force and tension when the fireworks are launched and rotated, prevent the rotating assembly 2 from separating from the pull rope assembly 1, and ensure the normal operation of the fireworks. Moreover, the rotating assembly 2 is arranged on the pull rope assembly 1, and connected by the shaft body receiving hole 201, which can make the assembly of the fireworks more convenient and quick, reduce the number and complexity of parts, reduce the difficulty of assembly, and improve production efficiency. Placing the fireworks placement component 3 on the rotating component 2 can ensure that the fireworks rotate with the rotating component 2, presenting a more colorful and dynamically changing fireworks show to the audience, increasing the viewing and interest of the fireworks, and through rotation, the light of the fireworks can be displayed at different angles and directions, expanding the visible range of the fireworks, allowing more people to appreciate the beauty of the fireworks.

[0033] like Figure 2 and Figure 4 As shown, in addition to the features of the above-mentioned embodiments, this embodiment further defines that: the pull rope assembly 1 includes a rope 11 and an assembly shaft 12, the rope 11 is arranged on the assembly shaft 12, and the assembly shaft 12 is arranged on the rotating assembly 2 and located at the shaft receiving hole 201. By arranging the rope 11 on the assembly shaft 12 and arranging the assembly shaft 12 on the shaft receiving hole 201 of the rotating assembly 2, the assembly shaft 12 serves as an intermediate component connecting the rope 11 and the rotating assembly 2, and plays the role of assembly and connection. The user can stand at both ends of the pull rope assembly 1 and grab the pull rope assembly 1, and then ignite the fireworks placed on the rotating assembly 2. The fireworks generate a driving force to drive the rotating assembly 2 to rotate, adding a dynamic element to the fireworks show.

[0034] like Figure 3As shown, in addition to the features of the above embodiments, this embodiment further defines that the assembly shaft body 12 includes a first half shaft body 121 and a second half shaft body 122. The first half shaft body 121 and the second half shaft body 122 cooperate with each other. The first half shaft body 121 is provided with a first mating groove 101, and the second half shaft body 122 is provided with a second mating groove 102. A part of the first half shaft body 121 is clamped at the second mating groove 102, and a part of the second half shaft body 122 is clamped at the first mating groove 101. By respectively arranging the first half shaft body 121 and the second half shaft body 122 in the second mating groove 102 and the first mating groove 101, and by mating the first half shaft body 121 and the second half shaft body 122 and positioning them in the corresponding mating grooves, the mating of the first mating groove 101 and the second mating groove 102 can help ensure that the second half shaft body 122 and the first half shaft body 121 have a high concentricity after assembly, which is crucial for the normal operation of the rotating assembly 2. Because if the two half shafts are not concentric, it will cause rotational imbalance, increased vibration, and even damage to other components. Through the precise design of the mating grooves, the two half shafts can be kept on the same axis as much as possible after assembly, thus ensuring the smoothness and accuracy of rotation. The mating grooves can also play a positioning role to ensure that the two half shafts can be correctly aligned during installation, avoiding installation errors. At the same time, the mating grooves can also provide additional contact areas and connection points, thereby enhancing the connection strength between the two half shafts, helping to ensure that the two half shafts will not easily separate or loosen under the action of high-speed rotation and various forces of the rotating assembly 2, and can effectively and firmly clamp the rope 11, improving the stability and reliability of the entire structure.

[0035] As Figure 1 and Figure 4As shown, in addition to the features of the above embodiments, this embodiment further defines: the rotating assembly 2 includes a shaft matching column 21, a chassis 22, a support block 23, a rotating plate 24 and a stop block 25, the pull rope assembly 1 is arranged on the shaft matching column 21, the shaft matching column 21 is arranged on the chassis 22, the shaft matching column 21 is provided with a shaft accommodating hole 201, the chassis 22 is provided with a wire groove 202, the rotating assembly 2 is assembled with the pull rope assembly 1 through the wire groove 202, the number of the support blocks 23 is multiple, and the multiple support blocks 23 are arranged around the shaft matching column 21, the number of the rotating plates 24 is multiple, and the multiple rotating plates 24 are arranged along the chassis 22, and the multiple rotating plates 24 are connected to the fireworks placement assembly 3, the stop block 25 is arranged on the shaft matching column 21 and is located in the shaft accommodating hole 201, the assembly shaft 12 is provided with an installation groove 103, and the stop block 25 cooperates with the installation groove 103. By setting the pull rope assembly 1 on the shaft body matching column 21, and setting the shaft body matching column 21 on the chassis 22, the chassis 22, as the structural basis of the rotating assembly 2, has a large area and weight, and can provide stable support for the shaft body matching column 21. The shaft body matching column 21 is installed on the chassis 22, and multiple support blocks 23 are arranged around the shaft body matching column 21, plus multiple rotating plates 24 are arranged along the circumference of the chassis 22 and connect the fireworks placement assembly 3, which can ensure that it remains vertical and stable during the rotation of the fireworks. Since the stop block 25 cooperates with the installation groove 103, the rotating assembly 2 will not easily shake, tilt or fall. At the same time, the pull rope assembly 1 is set on the shaft body matching column 21, and the stability of the shaft body matching column 21 can also be used to ensure that the pull rope assembly 1 will not shake significantly during the pulling process, so that the rotation start of the fireworks is more stable and reliable. This structure helps to enhance the strength of the fireworks launching device. The shaft body mating column 21 connects the chassis 22 and the pull rope assembly 1, which plays a role in transmitting force and enhancing structural strength. When the pull rope assembly 1 is pulled, the generated tension is transmitted to the shaft body mating column 21 through the pull rope assembly 1, and then transmitted to the chassis 22 by the shaft body mating column 21. The chassis 22 can withstand a large force, thereby dispersing and bearing the tension generated by the pull rope assembly 1, avoiding local excessive force and causing structural damage.

[0036] like Figure 4As shown, in addition to the features of the above-mentioned embodiment, this embodiment further defines that: the shaft body matching column 21 includes a main column 211 and a sub-column 212, the main column 211 and the sub-column 212 are both arranged on the chassis 22, the main column 211 and the sub-column 212 are arranged opposite to each other, a plurality of support blocks 23 are arranged around the main column 211 and the sub-column 212, and the main column 211 and the sub-column 212 enclose the shaft body receiving hole 201. By arranging the main column 211 and the sub-column 212 on the chassis 22, the chassis 22 can provide a stable basic support for the main column 211 and the sub-column 212 above, which can ensure that the entire structure can remain stable in various situations and is not easy to tip over or shake, and the main column 211 and the sub-column 212 are erected from the chassis 22 to form a relatively stable three-dimensional structure, thereby enhancing the overall anti-interference ability. Arranging multiple support blocks 23 around the main column 211 and the auxiliary column 212 can provide additional support for the main column 211 and the auxiliary column 212. When the fireworks device is subjected to various external forces during use, such as wind force, the recoil force of fireworks, etc., the support blocks 23 can share part of the pressure to prevent the main column 211 and the auxiliary column 212 from tilting or deforming, thereby enhancing the stability of the entire structure. At the same time, multiple support blocks 23 are arranged around to provide support forces from different directions, so that the main column 211 and the auxiliary column 212 can be well supported in all directions, further improving the stability of the structure. The shaft accommodating hole 201 formed by the main column 211 and the auxiliary column 212 allows the pull rope assembly 1 to be stably placed therein, providing basic support for the normal operation of the fireworks device. The shaft can rotate freely in the hole to achieve the rotating effect of the fireworks.

[0037] like Figure 4 and Figure 5As shown, in addition to the features of the above embodiments, this embodiment further defines that: the firework placement assembly 3 includes a top shell 31, a rear shell 32, and a connecting plate 33. The top shell 31 and the rear shell 32 are both arranged on the rotating assembly 2, and the connecting plate 33 is arranged on the rotating assembly 2 and connects the top shell 31 and the rear shell 32 respectively. By arranging the top shell 31 and the rear shell 32 on the rotating assembly 2, the combination of the top shell 31 and the rear shell 32 with the rotating assembly 2 forms a relatively stable overall structure, providing a stable installation platform for the fireworks. By placing the fireworks between the top shell 31 and the rear shell 32, the position of the fireworks can be effectively fixed, preventing them from shaking or shifting during rotation, which helps to ensure that the fireworks can be launched along the predetermined trajectory and direction, improving the effect and quality of the fireworks display. The stable installation can also reduce the possibility of unexpected situations during the launch of the fireworks, such as the fireworks falling, tilting, or deviating from the target, etc. Arranging the connecting plate 33 on the rotating assembly 2 and connecting the top shell 31 and the rear shell 32 constitutes a more stable frame structure. This frame can provide a stable placement space for the fireworks, preventing the fireworks from undergoing large displacements in all directions. The fireworks are wrapped within this frame and are supported and restricted from different directions, thereby enhancing the fixing effect on the fireworks. When the rotating assembly 2 rotates, the frame structure can withstand external forces such as centrifugal force, ensuring that the fireworks will not become loose or fall off due to rotation.

[0038] As Figure 4 and Figure 5As shown, in addition to the features of the above embodiments, this embodiment further defines that: the firework placement assembly 3 also includes a limit member 34 and a stop block 35, the limit member 34 is arranged on the rotating assembly 2, the limit member 34 is arranged opposite to the rear shell 32, the rear shell 32 is provided with a receiving groove 301, and the stop block 35 is arranged on the rotating assembly 2 and located in the receiving groove 301. By setting the limiting member 34 behind the rear shell 32, the user can easily place the fireworks in the receiving groove by using the elastic force of the limiting member 34, and can effectively prevent the fireworks from moving backwards during rotation, ensuring that the fireworks are always in the correct installation position, ensuring that the direction and angle of the fireworks are accurate, and limiting the backward movement of the fireworks helps to maintain the stable position of the fireworks in the entire fireworks placement assembly, which is crucial to achieving the expected effect of the fireworks, because the stable position can ensure that the combustion and explosion process of the fireworks is carried out according to the design, avoiding unexpected situations caused by position changes, such as fireworks deviating from the predetermined orbit, affecting the launch of other fireworks, etc. If the fireworks move backward too much during the rotation process, they may fall off from the rotating assembly 2, causing safety hazards. The existence of the limiting member 34 can greatly reduce this risk, ensuring that the fireworks are always kept in a safe position during the entire use process, protecting the safety of surrounding people and property. At the same time, the positioning block 35 is set on the rotating assembly 2 and located in the receiving groove 301, and the elastic force of the positioning block 35 can be used to further limit the movement of the fireworks from the side and other directions to achieve all-round restriction. This ensures that the fireworks are effectively fixed in all directions, greatly enhancing the stability of the fireworks position. Compared with the traditional method of using glue to stick the fireworks to the position, this elastic limit using the limit block 34 and the clamping block 35 is more secure and safer. Since the top of the clamping block 35 is facing the position where the fireworks are pushed into the installation, it is easier to put the fireworks into the receiving groove 301, which increases the convenience of the installation operation.

[0039] like Figure 4 and Figure 5As shown, in addition to the features of the above-mentioned embodiment, this embodiment further defines that: the positioning block 35 includes a fixing seat 351 and a top block 352, the fixing seat 351 is arranged on the rotating assembly 2, the top block 352 is arranged on the fixing seat 351, and the top block 352 is used to fix the position of the fireworks. By correspondingly arranging multiple top blocks 352 on multiple fixing seats 351, the combination of multiple top blocks 352 and fixing seats 351 can fix the fireworks at multiple positions, and can also help maintain the launch angle of the fireworks. During the launch of fireworks, due to the influence of recoil and other factors, the fireworks may change in angle. The fixing effect of the top block 352 can reduce such angle changes, ensuring that the fireworks always maintain a stable angle during the launch process, thereby improving the accuracy and reliability of the fireworks launch. If the fireworks are not well fixed, these forces may cause the fireworks to shake in the rotating structure or even fall off. The presence of the top block 352 can increase the friction and support force between the fireworks and the rotating assembly 2, reduce the shaking of the fireworks, and thus enhance the stability of the fireworks launching device. The presence of the top block 352 can greatly reduce the serious damage to the surrounding personnel and equipment, and improve the safety of the fireworks show.

[0040] like Figure 1 and Figure 4 As shown, in addition to the features of the above-mentioned embodiment, this embodiment further defines that: the number of the fireworks placement components 3 is multiple. By setting the number of the fireworks placement components 3 to be multiple, the fireworks setting device can store multiple fireworks, producing a more colorful, spectacular and shocking visual effect. Fireworks of different colors, shapes and effects bloom at the same time, which can attract the attention of the audience and enhance the viewing and fun of the fireworks show. Moreover, multiple fireworks bloom at different positions, which can create a picture with rich layers and create a dynamically changing visual effect, so that the audience can feel a richer visual experience.

[0041] like Figure 1 and Figure 6As shown, in addition to the features of the above-mentioned embodiment, this embodiment further defines: it also includes a handle assembly 4, the number of which is two, and the two handle assemblies 4 are arranged at both ends of the pull rope assembly 1, and the handle assembly 4 is provided with a matching hole 401, and the pull rope assembly 1 is adapted to the matching hole 401. By arranging the two handle assemblies 4 at both ends of the pull rope assembly 1, and the pull rope assembly 1 is located at the matching hole 401 provided on the handle assembly 4, firstly, the handle assembly 4 provides a convenient gripping position, so that the operator can more easily grasp the pull rope assembly 1, and the handle design at both ends makes the operation on both sides more comfortable and stable, and it is convenient to pull the pull rope with force. Secondly, the existence of the handle assembly 4 allows the operator to better control the strength of the pull rope. By holding the handle assembly 4, the pulling amplitude of the pull rope can be more accurately adjusted, so as to more accurately control the start-up and operation of the fireworks setting device. The pull rope assembly 1 is located at the matching hole 401, and the handle assembly 4 can play a role in fixing the pull rope position, which can prevent the pull rope from sliding or shifting during use, and ensure that the pull rope is always in the correct position, so as to effectively transmit power and control the fireworks setting device.

[0042] like Figure 1 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the handle assembly 4 includes a handle housing 41 and a matching piece 42, the handle housing 41 is correspondingly arranged on the matching piece 42, the matching piece 42 is arranged on the pull rope assembly 1 and at the end of the pull rope assembly 1, the handle housing 41 is provided with a placement hole 402, and the matching piece 42 is provided with a matching hole 401. By arranging the handle housing 41 on the matching piece 42, and arranging the matching piece 42 at both ends of the pull rope assembly 1, since the handle housing 41 is provided with the placement hole 402, an ergonomic gripping position is provided for the operator. Compared with directly holding the pull rope assembly 1, the shape and material of the placement hole 402 can better adapt to the shape of the hand, provide a more comfortable gripping feeling, and reduce hand fatigue. The matching hole 401 provided in the matching piece 42 provides a fixed position for the pull rope assembly 1. When installing, the rope of the pull rope assembly 1 is stretched and knotted, and then placed at the matching hole 401, which can effectively prevent the pull rope assembly 1 from sliding or shifting at will during use, thereby ensuring the safety of the fireworks device during use.
