The first tooth set 22b and the second tooth set 22c are provided as two double teeth coaxially connected, so that the transmission stability of the transmission tooth set 22 can be ensured to some extent. In other embodiments of the present utility model, only one duplex gear may be provided for the first tooth set 22b and the second tooth set 22c, where the first tooth set 22b is meshed with the driving tooth 22a and the second tooth set 22c, and the duplex gear for the second tooth set 22c is provided with the missing tooth gear 225.

In this embodiment, the striker 30 is provided with a striker 31, a ladder tooth 32, ribs 33, a retaining head 34 and a stopper 35. The striking head 31 is located at an end of the striking rod 30 opposite to the transmitting tube 11, and the end of the striking head 31 is outwardly protruded with a protruding head 311, and the protruding head 311 is made of an elastic material (such as silica gel, rubber, sponge, etc.) for cooperating with the positioning table 110 to eject the pellets out of the housing 10. It should be noted that, the raised head 311 made of the elastic material can further slow down the impact force and reduce the probability of breaking the fragile pellets such as water bullet. The step tooth 32 is located on the opposite side of the striker bar 30 from the edentulous gear 225 and is detachably engaged with the edentulous gear 225. The ribs 33 are disposed opposite to the guide grooves 122 and are in a concavo-convex fit connection therewith, and the ribs 33 are movably connected in the guide grooves 122 along the extending direction of the guide grooves 122. The retaining head 34 is located at the other end of the striker 30 facing away from the striker 31, and the retaining head 34 is elastically connected to the inner wall of the guide tube 12 by a spring (not shown) for allowing the striker 30 to move in the opposite direction in the guide tube 12 under the elastic force of the spring when the ladder tooth 32 is separated from the tooth missing gear 225. The stopper 35 is configured to be in abutting connection with the projection 123 and is configured to limit a limit position of the movement of the striker 30.

In other embodiments of the present utility model, when the guide tube 12 is not provided with the guide groove 122 and/or the protrusion 123, the striker 30 may be correspondingly not provided with the rib 33 and/or the stopper 35. When the striker 30 is otherwise elastically coupled to the inner wall of the guide tube 12 (e.g., by an elastic V-shaped rod, etc.), the striker 30 may not be provided with the retaining head 34. The nose 311 may also be made of a hard material.

It should be noted that, the working principle of the transmitting device provided in this embodiment is approximately: when the motor 21 is started, the transmission gear group 22 is driven to rotate, and at the moment, the tooth missing gear 225 rotates to be meshed with the ladder teeth 32, and the ladder teeth 32 drive the plunger 30 to move in a direction away from the launching tube 11, so that the spring between the plunger 30 and the inner wall of the guide tube 12 is stressed to compress and store energy. When the gear 225 rotates to a position separated from the ladder teeth 32, the striking rod 30 is not pushed, so that the striking rod 30 can move toward the direction of the launching tube 11 under the action of elastic force, and the striking head 31 can strike the pellets in the guide tube 12 to move rapidly, so that the pellets pass through the positioning table 110 and finally are ejected out of the launching tube 11, and the launching process is completed. That is, the striking rod 30 of the launching device can reciprocate in the guide tube 12 under the action of the driving gear group 22 and the elastic force, so as to realize continuous projectile launching.

For clarity, certain features of the utility model that are described in the context of separate embodiments may also be provided in combination in a single embodiment. Furthermore, the various features of the utility model which are described in the context of a single embodiment may also be used in combination in a subcombination, alone or in any suitable manner.
