A first embodiment of the present invention is directed to a firing device. As shown in fig. 1, 2, 3 and 4, the firing device includes: the device comprises a motor 1, a transmission component 2, a flywheel 3, an impact block 4, an elastic piece 5 and a striker 6, wherein the striker 6 is guided to a pipe 8. The guide pipe 8 is used for placing the struck object 11, the guide pipe 8 comprises a first pipe body 81 with the pipe orifice 80 and a second pipe body 82 vertically communicated with the first pipe body 81, the second pipe body 82 is used for placing the struck object 11, the struck objects 11 are sequentially arranged in the second pipe body 82 from bottom to top, the struck object 11 in the second pipe body 82 is pushed into the first pipe body 81, and the striker 6 pushes the struck object 11 entering the first pipe body 81 out of the pipe orifice 80. The transmission component 2 is connected with a main shaft of the motor 1, and the flywheel 3 is connected with the transmission component 2. The impact block 4 is rotatably connected to the flywheel 3, as in fig. 1, the impact block 4 is connected to the flywheel 3 by a pin 40. The beater 6 is rotatably connected with the flywheel 3, a bearing 10 is sleeved between the beater 6 and the flywheel 3, and the beater 6 cannot be driven to rotate by the rotation of the flywheel 3. The both ends of elastic component 5 are connected flywheel 3 and striking piece 4 respectively, and elastic component 5 is used for holding striking piece 4 when the rotational speed of flywheel 3 is not more than predetermineeing the rotational speed, and striking piece 4 rotates along with flywheel 3 with the same of flywheel 3 rotational speed this moment, and elastic component 5 is spring or shell fragment. When the rotating speed of the flywheel 3 is larger than the preset rotating speed, the impact block 4 rotates around the joint of the flywheel 3 and the impact block and impacts and pushes the striker 6. The beater 6 is provided with a beating main body 62 extending to the outer periphery of the flywheel 3, the beating main body 62 is inserted into the guide pipe 8 and is positioned in the first pipe body 81, when a beaten object 11 enters the first pipe body 81, the beating main body 62 is positioned between the pipe orifice 80 and the beating main body 62, and when the beaten object 11 is driven by the beater 6 to rotate, the beaten object 11 moves towards the pipe orifice 80 to be beaten, so that the beaten object 11 is ejected from the pipe orifice 80. The direction in which the struck object 11 is ejected is shown by an arrow a in fig. 1, and an arrow B is a direction in which the striker 6 rotates after being struck.

Through the above, it is easy to find that the transmission assembly is driven by the motor 1 to transmit, the transmission assembly drives the flywheel 3 to rotate, when the rotating speed of the flywheel 3 is greater than the preset speed, the impact block 4 overcomes the tensile force of the spring to rotate, the impact block 4 impacts and pushes the impactor 6, the impact main body 62 of the impactor 6 is driven by the impactor 6 to rotate, the object 11 to be impacted is impacted in the guide pipe 8, and the object 11 to be impacted is launched. Therefore, the struck object 11 is launched through the rotation of the motor 1, no gunpowder is ignited, the environmental pollution is reduced, no explosive sound exists, the noise is reduced, and the safety is ensured. The speed of the flywheel 3 can be adjusted by adjusting the rotating speed of the motor 2, so that the force of the impact block 4 impacting the impactor 6 is adjusted, the elastic thrust of the impactor 6 pushing the object 11 to be impacted is further adjusted, and the control of the launching distance and the height of the object 11 to be impacted is realized. So that the emission of the hit object 11 is more controllable and can be more accurately aligned with the ground to be emitted.

As shown in fig. 3 and 4, the transfer assembly 2 includes: the motor comprises a first gear 21, a clutch 22, a connecting shaft 23 and a second gear 24, wherein the first gear 21 is connected with a main shaft of the motor 1, the second gear 24 is meshed with the first gear 21, and the connecting shaft 23 is fixedly sleeved with the second gear 24. The coupling shaft 23 is connected to the clutch 22, and the clutch 22 is connected to the flywheel 3. The motor 1 rotates to drive the first gear 21 to rotate, the first gear 21 rotates to drive the second gear 24 to rotate, the second gear 24 rotates to drive the clutch 22 to rotate, and the clutch 22 rotates to drive the flywheel 3 to rotate. The clutch 22 eliminates the reaction when in operation, namely no recoil, and when in use, the electric power consumption is small, the energy is saved, the service life is longer, and the service life is prolonged.

As shown in fig. 3, the flywheel 3 is fixed to a housing of the clutch 22.

Further, as shown in fig. 1, 2, 3 and 4, the end of the impact block 4 connected to the elastic member 5 is heavier than the end of the impact striker 6. Therefore, when the rotating speed of the flywheel 3 is greater than the preset rotating speed, the heavier end of the impact block 4 can fly out under the action of gravity, the impact block 4 rotates around the pin 40, and the lighter end of the impact block 4 impacts the striker 6, so that the striker 6 rotates. And a pressure steel ball 41 is placed at the heavier end of the impact block 4 to increase the weight of one end of the impact block 4.

Further, as shown in fig. 1, 2, 3 and 4, the striker 6 includes: the transmission shaft 61 that sets up with the flywheel 3 is coaxial, with the one end bending connection's 63 that transmission shaft 61 extends to the flywheel 3 outside, and the one end that transmission shaft 61 was kept away from to connecting portion 63 is connected strikes main part 62, strikes main part 62 and transmission shaft 61 bending connection setting. The free end of the striking body 62, i.e. the end extending into the first tube 81, is operatively disposed opposite the mouth 80 of the guide tube 8. The drive shaft 61 has a radially projecting lug 610 thereon. The flywheel 3 has a radially extending recess 30, the projection 610 is in the recess 30, the impact block 4 is also mounted in the recess 30, the impact block 4 rotates the impact projection 610, and the recess 30 is arranged to allow the impact block 4 to rotate without interference. The connecting portion 63 is vertically connected with the transmission shaft 61, the striking main body 62 is vertically arranged with the connecting portion 63, the striking main body 62 is also vertically connected with the transmission shaft 61, the striking main body 62 is parallel to the first pipe 81 when the striking main body 62 strikes the struck object 11 and the struck object is ejected, and the connecting portion 63 is parallel to the second pipe 82. It is understood that the striking body 62, the transmission shaft 61 and the connecting portion 63 may not be perpendicular but may be at other angles.

In addition, as shown in fig. 3 and 4, the connecting portion 63 is disposed perpendicular to the transmission shaft 61, and the length of the connecting portion 63 is greater than the radius of the flywheel 3, and the striking head 62 is disposed perpendicular to both the connecting portion 63 and the transmission shaft 61. Therefore, the striking body 62 can be more conveniently inserted into the guide pipe 8 without being interfered by the flywheel 3, and the striking body 62 can move more smoothly while being convenient to install.

As shown in fig. 4, the side wall of the flywheel has a pair of oppositely disposed flat surfaces 31, and the distance between the pair of flat surfaces is smaller than the diameter of the flywheel 3. Therefore, the overall structure of the flywheel provided with the striker 6 is simpler and lighter, the connecting part 63 can be positioned outside the periphery of the flywheel 3 when the transmission shaft 61 is arranged for a short time, and materials are saved. The plane 31 is also convenient to install, and other parts can be installed in the area beside the plane 31, so that the overall layout of the firing device is more compact.

Finally, as shown in fig. 1 and 2, the struck object 11 launching device further includes a battery compartment 9 for supplying power to the motor 1. The device is convenient for the struck object 11 to run at any time, and is more beneficial to moving in more environments. And the triggered device can also be powered by an external power supply.

It will be understood by those of ordinary skill in the art that the foregoing embodiments are specific examples for carrying out the invention, and that various changes in form and details may be made therein without departing from the spirit and scope of the invention in practice.
