The invention provides an integral clamping mechanism of an aircraft traction rod, and belongs to the technical field of aircraft traction equipment. The technical problem that safety is poor due to the fact that a tractor drags an airplane through a traction rod is solved. The integral clamping mechanism of the airplane traction bar comprises a first clamping head, a second clamping head, a first supporting rod and a second supporting rod, the first supporting rod and the second supporting rod are arranged on the two sides of the draw bar in the length direction of the draw bar, and a first guide rod is arranged between the first supporting rod and the first clamping head. The first guide rod is sleeved with a first guide block and a first reset spring located between the first guide block and the first clamping head, a second guide rod is arranged between the second supporting rod and the second clamping head, and the second guide rod is sleeved with a second guide block and a second reset spring located between the second guide block and the second clamping head. A wedge-shaped block and a telescopic piece which can drive the wedge-shaped block to move so that the first clamping head and the second clamping head can get close to each other or get away from each other are arranged between the first supporting rod and the second supporting rod. One degree of freedom of the draw bar can be reduced, and the safety of the draw bar for drawing an airplane is improved.

    本发明提供了一种飞机牵引杆的整体式夹紧机构,属于飞机牵引设备技术领域。它解决了牵引车通过牵引杆牵引飞机的安全性差等技术问题。本飞机牵引杆的整体式夹紧机构包括夹紧头一和夹紧头二及沿牵引杆长度方向的支杆一和支杆二,支杆一和支杆二设置在牵引杆两侧,支杆一和夹紧头一之间设有导向杆一,导向杆一上套设有导向块一和位于导向块一及夹紧头一之间的复位弹簧一,支杆二和夹紧头二之间设有导向杆二,导向杆二上套设有导向块二和位于导向块二及夹紧头二之间的复位弹簧二,支杆一和支杆二之间设有楔形块和能带动楔形块移动使夹紧头一和夹紧头二相互靠近或远离的伸缩件。本发明能减少牵引杆一个自由度,提高牵引杆牵引飞机的安全性。
