Driving force transmission pin 100a is in correct position, two end is engaged with corresponding engaging claw 11 ' respectively, and respectively to two
Engaging claw 11 ' applies torque T 1 equal in magnitude and opposite direction so that and rotary driving force receiving member 10 ' normally rotates, from
And it can steadily transmit rotary driving force.
Referring next to Fig. 4 b, wherein rotary driving force transmission pin 100a is moved due to loosening along its axis, drive shaft 100
Change with the relative position of rotary driving force transmission pin 100a, only rotary driving force transmission pin 100a a end can with connect
It closes the engagement of pawl 11 ' and applies torque T 1 to the engaging claw, while the spherical free end of drive shaft 100 receives structure with rotary driving force
The spherical concave surface of part 10 ' contacts and generates torque T 2, and torque T 2 is much smaller than torque T 1, so that rotary driving force receives structure
Part 10 ' rotates relative to axis because of force unbalance and swings；Correspondingly, drive shaft 100 is because of rotary driving force reception
The reaction force of component 10 ' and equally rotate relative to axis and swing, eventually lead to two engaging claws 11 ' with rotation
Driving force transmission pin 100a is detached from.
