The invention discloses an unmanned aerial vehicle with telescopic vehicle arms. The unmanned aerial vehicle comprises a vehicle body, a vehicle arm, a guide groove and a rotor wing assembly, whereinthe vehicle arm comprises a first arm rod and a second arm rod, one end of the first arm rod is connected with the vehicle body, a movable fastening shaft is arranged on the first arm rod, a flexiblepad is arranged at one end of the fastening shaft, and a limiting protrusion is arranged on the inner circumferential wall of the first arm rod; the guide groove extending in the axial direction of the second arm rod and is formed in the peripheral wall of the second arm rod, a plurality of limiting grooves are formed in the groove bottom wall of the guide groove and distributed in the length direction of the guide groove at intervals, the second arm rod slidably extends into the first arm rod, and the limiting protrusions are located in the guide groove; the second arm rod slides to enable the limiting protrusion to be matched with one limiting groove, and the fastening shaft moves to enable the flexible pad to abut against the second arm rod to fix the second arm rod. and the rotor wingassembly is arranged at the end, away from the first arm rod, of the second arm rod, and the device can achieve extension and retraction of the vehicle arm.

    本发明公开了一种具有伸缩机臂的无人机,包括:机身;机臂,机臂包括第一臂杆和第二臂杆,第一臂杆的一端与机身相连,第一臂杆上设有可移动的紧固轴,紧固轴的一端设有柔性垫,第一臂杆的内周壁上设有限位凸起;第二臂杆的外周壁上设有沿第二臂杆轴向延伸的导向槽,导向槽的槽底壁设有限位凹槽,限位凹槽为多个,多个限位凹槽沿导向槽的长度方向间隔排布,第二臂杆可滑动地伸入第一臂杆内,限位凸起位于导向槽内,第二臂杆滑动以使得限位凸起与其中一个限位凹槽配合,紧固轴移动以使得柔性垫与第二臂杆抵接以固定第二臂杆;旋翼组件,旋翼组件设于第二臂杆的远离第一臂杆的一端,本装置可实现机臂的伸缩。
