[0020] Referring to Figs. 1-2 The utility model provides an embodiment:

[0021] A labor-saving unmanned plane throwing mechanism, including throwing base 1, the outer surface of throwing base 1 is provided with control mechanism, limiting mechanism and connecting rod A 911, control mechanism is responsible for driving limiting mechanism to act, the function of limiting mechanism is to limit the position of connecting rod A 911, the outer surface of one side of throwing base 1 is fixedly installed with cylinder pin B 6, connecting column 8 and cylinder pin A 9 respectively, connecting rod A 911 is rotatably installed at the outer surface of cylinder pin A 9, and cylinder pin A 9 is used for load operation, when limiting mechanism removes the limitation of cylinder pin A 9, connecting rod A 911 rotates around cylinder pin A 9 under the action of gravity, to achieve the purpose of releasing load.

[0022] Further, the limiting mechanism is composed of chain 4, connecting rod B 5 and tension spring 7, connecting rod B 5 is rotatably installed at the outer surface of cylinder pin B 6, one end of connecting rod B 5 is connected with tension spring 7, one end of tension spring 7 is connected with connecting column 8, the other end of connecting rod B 5 is connected with chain 4, the rotatable installation of connecting rod B 5, the elastic force of tension spring 7 and the tension transmission of chain 4 jointly constitute a stable and reliable limiting system, which ensures the safety of the throwing mechanism during the flight of the unmanned plane.

[0023] Further, the control mechanism is composed of steering gear 2 and steering gear arm 3, one end of steering gear 2 is fixed to the outer surface of throwing base 1, one side of steering gear 2 is connected with steering gear arm 3, one end of steering gear arm 3 is connected with chain 4, the use of steering gear 2 improves the high precision and reliability of the control mechanism, which is essential to ensure that the throwing mechanism can accurately and stably complete the throwing task during the flight of the unmanned plane.

[0024] Further, a plurality of screw grooves 912 are formed on the top end of the outer surface of the throwing base 1, which facilitates the connection and installation with the unmanned plane.

[0025] Further, one end of connecting rod A 911 and connecting rod B 5 is in right angle shape, which is used for mutual engagement and stability between the two groups, and the right angle design can ensure that the connecting rod is not easy to fall off or loosen under stress, thereby improving the reliability and safety of the whole throwing mechanism.

[0026] Further, the outer surface of the connecting rod A911 is wrapped with rubber, which has good friction and elasticity, and can increase the friction between the connecting rod and the mounted article or connecting component, preventing the article from slipping or loosening.

[0027] Working principle: before the unmanned aerial vehicle takes off and prepares to carry out the throwing task, the connecting rod A911 carries the article to be thrown, and is stably clamped with the connecting rod B5 through the right-angle end. The chain 4 is connected to the other end of the connecting rod B5 and is in a taut state, and through the tension of the chain, the connecting rod B5 and the connecting rod A911 form a stable limiting structure. When the unmanned aerial vehicle reaches the specified throwing position, the rudder 2 in the control mechanism starts to work. The rudder 2 drives the rudder arm 3 to rotate, and the rudder arm 3 pulls the connecting rod B5 through the chain 4. Due to the tension of the chain, the connecting rod B5 rotates around the cylindrical pin B6, gradually releases the limitation on the connecting rod A911, and as the connecting rod B5 rotates, the connecting rod A911 loses the limit and starts to rotate around the cylindrical pin A9 under the action of gravity. With the rotation of the connecting rod A911, the article mounted thereon is smoothly released, and after the load is released, the rudder 2 continues to work to control the rudder arm 3 to rotate reversely, thereby releasing the tension of the chain 4 on the connecting rod B5. At this time, the tension spring 7 starts to work, and pushes the connecting rod B5 to rotate reversely around the cylindrical pin B6 by using the elastic force, until it returns to the initial state. With the resetting of the connecting rod B5, the whole throwing mechanism returns to the initial state.
