For some beginners, they can already be flown by hand, and the price is relatively low. Remote control aircraft have entered ordinary families, with fun as the main direction; some enthusiasts also modify them to achieve more entertainment (such as aerial photography, load carrying, etc.). Because the rear wheels of the aircraft often collide during landing or takeoff taxiing, the servo of the remote control aircraft is easily damaged.

DETAILED DESCRIPTION
[0018] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.
[0019] Please combine Figure 1-4 A tail pulley change-of-direction structure of a remote-controlled aircraft of the present embodiment comprises: an aircraft shell, a server, and a control circuit board. The aircraft shell is assembled from two left and right side panels. An installation cavity for installing a control component is provided inside the aircraft shell. A flying wing is provided in the middle of the aircraft shell. A server is provided above the flying wing. A connecting swing arm is provided on the top of the rotating shaft of the server. The connecting swing arm is connected to a clutch structure through a connecting rod. The rear wheel of the aircraft is connected to the clutch structure. The clutch structure is installed in a slot at the tail of the aircraft shell. The control circuit board is electrically connected to the server and a power supply. The server is installed on a fixed bracket. The fixed bracket is fixed to the installation slot of the aircraft shell.
[0020] In the above scheme, the clutch structure is mainly composed of a fixed seat, a central shaft, a buffer spring, a clutch rotating block and an upper top block. The central shaft is arranged in the middle of the fixed seat, the bottom of the central shaft is connected to the rear wheel of the aircraft, the buffer spring is sleeved on the top of the central shaft, the upper top block is arranged on the top of the central shaft, and the clutch rotating block is connected to the connecting swing arm through a connecting rod. The upper top block is fixed to the top of the central shaft by bolts, the clutch rotating block located below the upper top block is sleeved on the top of the central shaft, the clutch rotating block moves up and down along the central shaft, and the bottom of the upper top block and the top of the clutch rotating block are both provided with waved circular ring columns, and the upper and lower waved circular ring columns are meshed with each other.
[0021] In the above scheme, a connecting portion extends outward from one side of the clutch rotating block, and two circular holes are provided on the connecting portion. One side of the connecting swing arm extends outward to form an extension plate, and two holes are provided on the extension plate. One end of the connecting rod is connected to the circular hole on the connecting portion, and the other end of the connecting rod is connected to the hole of the extension plate.
[0022] In the above scheme, one end of the buffer spring is pressed against the inside of the fixing seat, and the other end of the buffer spring is pressed against the disc of the central axis. Below the disc of the central axis is a cross cylinder, and a square slot is arranged inside the cross cylinder. One end of the connecting strip of the rear wheel of the aircraft is inserted into the square slot, and the other end of the connecting strip is hinged to the rear wheel of the aircraft. The fixing seat is inserted into the slot at the tail of the aircraft shell, and a circle of snap rings is arranged outside the fixing seat, and the clutch rotating block is located at the top of the fixing seat.
[0023] Steering principle: The control circuit board receives the control signal and sends a signal to the server. The servo shaft drives the connecting swing arm. When the connecting swing arm swings to a certain angle, the connecting swing arm can rotate the clutch block through the connecting rod, and the clutch block drives the entire central axis to rotate, thereby realizing the change of direction of the aircraft's rear wheels.
[0024] Clutch buffering principle: A buffer spring is set inside the clutch structure. When the remote-controlled aircraft is landing or taking off, the rear wheels of the aircraft need to glide. During the glide, the rear wheels of the aircraft will be subject to a certain degree of vibration, and the buffer spring can effectively filter out most of the vibration to avoid damage to the server. When the rear wheels of the aircraft are hit by a large external force, the buffer spring will be compressed to separate the upper block and the clutch rotating block from each other. At this time, the rear wheels of the aircraft are in a slipping state, and the external force will not be directly transmitted to the server, which can better protect the server and other components.
[0025] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
