U型方型多轴器：
Type U square shaft multi-spindle tool
方型可调式多轴器结构与圆型相同。工作孔距如属直线或长方型万向多轴器，以免移位置太大损害万向节接头寿命。使用方法与圆型相同。（尽量配合工作之孔距坐标，设计齿轮箱结构即定镗孔位）
The structure of the square shaft multi-spindle tool is the same as the structure of the round shaft multi-spindle tool.
This multi-spindle tool is suitable for the straight line of the rectangular working hole. When using, don't move too muchto reduce the lifetime of the cardan joint. The usage is also the same as the round shaft one.
(When designing the structure of the gear case or the position of the bore, try to build the coordinate per working hole.)
万向节注意事项：
1、调整时不能超过规定的角度15度。
2、如超过此极限心轴易磨损或断裂。
3、工作时应经常加润滑油脂。
Note of cardan joint:
1、DO not set the angle to more than the specified
     15 degrees.
2、If the limit is exceeded, the shaft will be easy to
      wear or break.
3、During work, lubrication should be added
      frequently.

万向节组装注意事项
Note of cardan joint installation
U 型多轴器输出轴由上下2个万向节配合六角传动轴组成，组装时须注意万向节内侧爪须同一位置、方向，以免造成挠曲偏摆量
过大损及其寿命。
Tthe output shafts of the type U multi-spindle tool consist of two (up and down) cardan joint and hexagonal driven shafts.
When installing, note to have the inner clutches of the cardan joint in the same position and direction, and avoid too much
wrest or twist that may cause damage or influence thelifetime.
