DETAILED DESCRIPTION

[0017] The technical solution of the utility model is further described below in conjunction with the accompanying drawings.

[0018] Embodiment 1: A protective frame for setting off large fireworks, such as Figure 1-Figure 3 As shown, it includes a base frame 1, the bottom of which is connected with four universal wheels 2 by bolts, the four universal wheels 2 are evenly spaced, a hand push frame 3 is fixedly connected to one side of the base frame 1, the hand push frame 3 is used to push the base frame 1, a rotating mechanism is provided on the base frame 1, and a clamping mechanism is provided on the base frame 1, the rotating mechanism is used to adjust the firing angle of fireworks to facilitate multi-angle firing, and the clamping mechanism is used to clamp the fireworks during firing to improve the stability of the fireworks and increase the safety of firing.

[0019] The rotating mechanism includes a rotating shaft 5, which is rotatably connected to the base frame 1, and a movable plate 6 is fixedly connected to the rotating shaft 5. The rotating shaft 5 is used to drive the movable plate 6 to rotate, and the bottom of the movable plate 6 is in contact with the top of the support plate 4. The support plate 4 is used to support the movable plate 6. A vertical plate 7 is fixedly connected to the movable plate 6, and the vertical plate 7 is perpendicular to the movable plate 6. A motor 8 is fixedly connected to the base frame 1, and a transmission assembly 9 is provided between the output shaft of the motor 8 and the rotating shaft 5. The motor 8 drives the rotating shaft 5 to rotate through the transmission assembly 9, and then drives the movable plate 6 to rotate.

[0020] The transmission assembly 9 includes a driving wheel, a driven wheel and a transmission belt. The driving wheel is fixedly connected to the output shaft of the motor 8, and the driven wheel is fixedly connected to one end of the rotating shaft 5. A transmission belt is wound between the driving wheel and the driven wheel, and the driving wheel drives the driven wheel to rotate through the transmission belt.

[0021] The clamping mechanism includes a mounting seat 10, the mounting seat 10 is fixedly connected to the vertical plate 7, a threaded rod 11 is rotatably connected to the mounting seat 10, the mounting seat 10 is used to install the threaded rod 11, the threaded rod 11 is provided with opposite threads, two sliding frames 12 are slidably connected to the vertical plate 7, the two sliding frames 12 are symmetrically arranged, the sliding frames 12 are connected to the threaded rod 11 by threads, the threaded rod 11 is used to drive the sliding frames 12 to move, a clamping plate 13 is fixed to the sliding frame 12, the threaded rod 11 drives the sliding frame 12 to move, and then drives the clamping plate 13 to move.

[0022] At the beginning, the staff holds the hand push frame 3 and moves the device to the firing point, and then places the fireworks on the movable plate 6 so that one side of the fireworks is in close contact with the vertical plate 7. When the firing angle of the fireworks needs to be adjusted, the staff starts the motor 8, and the output shaft of the motor 8 rotates through the transmission assembly 9 to drive the rotating shaft 5 to rotate, and the rotation of the rotating shaft 5 drives the movable plate 6 to rotate, and the rotation of the movable plate 6 drives the vertical plate 7 and the fireworks to rotate. Through the above operations, the firing angle of the fireworks can be conveniently adjusted to facilitate multi-angle firing. The movable plate 6 rotates to disengage from the support plate 4, and the vertical plate 7 will limit the fireworks. When the firing angle is adjusted, the staff turns off the motor 8 and rotates the threaded rod 11. Under the action of the threads on the threaded rod 11, the two sliding frames 12 will move in a direction approaching each other, and the two sliding frames 12 move in a direction approaching each other, driving the two clamping plates 13 to move in a direction approaching each other. The two clamping plates 13 move in a direction approaching each other. The two clamping plates 13 move in the direction away from each other, and the two clamping plates 13 move in the direction away from each other and break contact with the fireworks. Then the staff takes away the fireworks after they have been set off and adjusts the motor 8 to rotate in the opposite direction. The output shaft of the motor 8 rotates in the opposite direction to drive the shaft 5 to rotate in the opposite direction through the transmission assembly 9. The shaft 5 rotates in the opposite direction to drive the movable plate 6 to rotate in the opposite direction. The movable plate 6 rotates in the opposite direction to drive the vertical plate 7 to rotate in the opposite direction.

[0023] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 2 and Figure 4 As shown, a stabilizing mechanism is also included. The base frame 1 is provided with the stabilizing mechanism, and the stabilizing mechanism includes a mounting frame 14. Two mounting frames 14 are fixedly connected to the base frame 1, and the two mounting frames 14 are symmetrically arranged. A fastening nail 15 is slidably connected to the mounting frame 14, and the fastening nail 15 is used to increase the stability of the base frame. The fastening nail 15 is perpendicular to the bottom surface. A magnet 16 is fixedly connected to the bottom of the mounting frame 14, and a pedal 17 is fixedly connected to the lower end of the fastening nail 15. The pedal 17 is used to drive the fastening nail 15 to move up and down. The pedal 17 is made of iron material, and the pedal 17 is in contact with the magnet 16.

[0024] Initially, the magnet 16 is in contact with the pedal 17, and the magnet 16 absorbs the pedal 17, thereby limiting the position of the fastening nail 15. Before the fireworks are set off, the staff steps on the pedal 17 downward, and the pedal 17 moves downward and loses contact with the magnet 16. The magnet 16 no longer absorbs the pedal 17, thereby no longer limiting the position of the fastening nail 15. The pedal 17 continues to move downward to drive the fastening nail 15 to move downward, and the fastening nail 15 moves downward and will be inserted into the soil. Through the above operation, the stability of the fireworks can be further improved, and the safety of the setting off can be further increased. After the setting off is over, the staff pushes the pedal 17 upward, and the pedal 17 moves upward to drive the fastening nail 15 to move upward. The pedal 17 continues to move upward and contacts with the magnet 16, and the magnet 16 re-absorbs the pedal 17, thereby re-limiting the fastening nail 15.

[0025] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
