本发明所述的第三通孔由设置在圆角梯形片外侧大孔及设置在圆角梯形片内侧小孔组成，所述大孔与小孔连通，大孔的直径大于小孔。
本发明所述的大孔内设有轴承。
本发明所述的拉杆的下端设有套环，在拉杆的上端设有第三轴套，所述第二轴套设置在第三轴套内，金属销穿过第四通孔、第二轴套并且将拉杆连接在希拉控制臂上，套环套在球头上。
本发明与现有技术相比，采用一组向位器装置替代传统的两组对称设置的向位器，在不影响向位器装置实现功能的基础上，减少零件的用量，进一步降低了生产成本。

具体实施方式
下面结合实施例对本发明的技术方案作进一步的详细说明。
如图1和图2所示，本发明的遥控模型直升机的向位器装置，设有一组向位器装置15，该向位器装置15连接倾斜内盘8上的球头12，向位器装置15包括中心座3、希拉控制臂4和拉杆9，其中：
如图3所示，所述中心座3由横向设置的矩形块31和设置在矩形块31下端的立柱32组成，该立柱32设置在矩形块31的中部，该矩形块31上横向设有第一通孔33，遥控模型直升机的旋翼16轴接在第一通孔33内，在立柱32的一侧与矩形块31平行的设有突起13，该突起13与立柱32连接构成L型结构，在突起13上横向设有第二通孔14，该第二通孔14与第一通孔33呈90度夹角设置；
如图4所示，所述希拉控制臂4由两个圆角梯形片41和连接两个圆角梯形片41的连接片42组成，该圆角梯形片41与连接片42构成N字型结构，连接片42设置在圆角梯形片41的长边一侧，在靠近连接片42一侧的圆角梯形片41上设有第三通孔43，在圆角梯形片41的短边一侧设有第四通孔44；

当主轴旋转时，主轴带动中心座3，中心座3带动希拉控制臂4转动，同时希拉控制臂4带动塑胶连杆9及倾斜内盘8，保证倾斜内盘8能与主轴同步旋转。
本发明中的向位器装置只连接了倾斜内盘上的一个球头，只需用1组向位器装置就能实现控制倾斜内盘旋转方向与角度的功能，比现有模型所采用的向位器装置少用了1组，零件使用数量上的减少，进一步降低了模型产品的生产成本。
