The invention relates to a telescopic handle of a ship propeller, which comprises a handle rod and a handle tube which is sleeved on the handle rod and can axially move relative to the handle rod, and is characterized in that the handle rod is provided with a through hole which axially extends, and a rotating rod which can extend into the through hole and can axially move together with the handle tube is rotatably arranged in the handle tube; the outer wall face of the rotating rod is at least provided with a section of smoothly-connected outer arc face with the radius gradually increased in the circumferential direction, the inner wall face of the through hole is at least provided with a section of smoothly-connected inner arc face with the radius gradually increased in the circumferential direction, and when the rotating rod rotates in the through hole till the outer arc face corresponds to the inner arc face, the rotating rod is in clearance fit with the through hole. And when the rotating rod rotates in the through hole until the outer cambered surface is staggered on the inner cambered surface, the rotating rod is tightly matched with the through hole and is in a locking state. By the adoption of the structure, the handle pipe can be reliably positioned at any position at any time in the required state, stepless adjustment of the telescopic length of the handle can be achieved, and positioning is more reliable.

    本发明涉及一种船用推进器的伸缩式把手,包括有把手杆和套在把手杆上且能相对于把手杆轴向移动的把手管,其特征在于把手杆上开有轴向延伸的通孔,把手管的内转动地安装能伸入到该通孔内且能与把手管一起轴向移动的旋转杆,该旋转杆的外壁面上至少具有一段顺滑衔接的沿周向半径逐渐增大的外弧面,通孔的内壁面上至少具有一段顺滑衔接的沿周向半径逐渐增大的内弧面,且旋转杆在通孔内旋转至外弧面对应内弧面时,旋转杆与通孔相间隙配合;当旋转杆在通孔内旋转至外弧面错位于内弧面时,旋转杆与通孔相紧配而处于锁紧状态。采用上述结构,可以让把手管随时可靠地定位在任意位置所需状态下而能实现把手的伸缩长度的无极调节,且定位更加可靠。
