Use steps of quick locking pin:
1. Rotate the bolt so that the five balls in the lock pin completely fall into the lock pin.
2. Insert into the standard hole, then turn the screw clockwise to make the ball inside the lock pin protrude.
3. Finally, fully tighten the locking pin with an Allen wrench.
4. When taking out, rotate it anticlockwise for several turns, and take out the lock pin when the ball completely falls into the lock pin.
Note: due to the unique structural design of this type of lock pin, whether the screw is screwed up or down to the end, the ball inside the lock pin will protrude, so the lock pin cannot be pulled out. Therefore, as a new user, when using the lock pin, pay special attention to whether the ball has completely fallen into the lock pin, and do not use brute force to knock out the lock pin, so as to avoid damaging the platform hole Position accuracy (generally from the tightening state to the time when the ball is completely trapped in the lock pin, rotate it 6 times anticlockwise manually). When locking, first tighten it clockwise by hand, and then tighten it with an Allen wrench.
Countersunk locking pin: it is convenient for the platform and auxiliary parts to be connected closely by rotating the pin screw. The locking body and the head of the pin screw have countersunk heads. After the pin is tightened, it just fits with the chamfer of the platform hole. The clamping will not interfere with the external, and the locking force is large, which is commonly used in the parts that are not often disassembled.
