[0030] A control device is also fixed between the two gun body side plates 52. The control module is arranged between the front direction control follower mechanism 6 and the reaction force buffer follower mechanism 7. The control module is electrically connected to the two servos 61 respectively for controlling the rotation of the output shaft of the servo 61.

[0031] The control module is connected to the remote control module signal on the ground, so that the staff can remotely control the rotation direction of the servo 61 through remote control, thereby changing the up and down angle of the gun barrel and increasing the water flushing area.

[0035] like Figure 5 As shown, the reaction force buffer follower mechanism 7 includes a resetter adjustment fixing member 71, a rear sliding sleeve assembly 73 and an oil pressure spring resetter 72. The resetter adjustment fixing member 71 is sleeved on the barrel 2 and is located behind the front sliding sleeve assembly 63. The top is hinged to one end of the oil pressure spring resetter 72. The other end of the oil pressure spring resetter 72, i.e., the telescopic end, is connected to the rear sliding sleeve assembly 73.

[0042] When the water gun 1 sprays a water column, it will generate a backward recoil force. At this time, the front direction control follower mechanism 6 slides backward under the action of the front sliding sleeve assembly 63, and the fixed assembly 5 also moves backward with the front direction control follower mechanism 6. The reaction force buffer follower mechanism 7 arranged at the rear end of the fixed assembly 5 also moves backward under the action of the fixed assembly 5. At this time, with the cooperation of the oil pressure spring returner 72, the rear sliding sleeve assembly 73 and the front sliding sleeve assembly 63, part of the recoil force can be absorbed, and the barrel 2 can be driven to reset after the recoil force subsides, thereby reducing the pressure of the drone to automatically correct the balance and improving the flight stability.

[0043] The parts not involved in the present invention are the same as the existing technology or can be implemented by using the existing technology.

[0044] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself.
