Sometimes it is also used as a safety device to prevent the coupled machine parts from bearing excessive load, and plays the role of overload protection, mainly used to couple the driving shaft and the driven shaft of different mechanisms firmly to rotate together, and transmit the mechanical parts of movement and torque. Sometimes also to couple the shaft with other parts (e.g. gears, pulleys, etc.). Usually, the two halves are combined and fastened to the two shaft ends by a key or a tight fit, and then the two halves are connected in a certain way. The coupling can also compensate the offset between the two shafts due to inaccurate manufacture and installation, deformation or thermal expansion in operation, and the like.
The existing pin-and-column type coupler carries out transmission by directly inserting the elastic pin, and the whole coupler is loose and easy to fall off due to the connection mode.
