Snap-on Shackle Kit

A randomly combinable shackle kit features a universal buckle plate where various toys can be inserted to form different shackles The buckle automatically fastens, and sliding the latch unlocks it An updated version of the lock structure was recently released, using a sliding cover plate that can be secured with a hidden lock or a 20-25mm padlock (this also includes timed locks or Yijuanci's heart-shaped Bluetooth locks) to self-lock the latch The new version moves the Phillips head of the screw to the back side, because friends found that the old version could be opened from the front with a screwdriver haha The complete set recommends 3 buckle plates plus 1 extension rod plus the full kit to achieve multiple functions

Currently, only the hardware version is complete a non-hardware version may be developed later

The hardware used is uniformly M3*20 round head screws and standard M3 nuts The springs used are the most common springs found in ballpoint pens For small productions, materials can be sourced locally
