Weight: ≤ 255g (without key and package);

Implementation standard: "GA1512-2018 public security single police equipment metal handcuffs"

Safety: When in the anti-lock positioning state, the fan teeth cannot rotate; When locking, the anti-dial net working time should be greater than or equal to 2min; When locking, after falling from a height of 2m to the concrete floor, it can normally open, lock and anti-lock positioning;

Durability: working times shall not be less than 7000 cycles;

Firmness: after the horizontal and vertical static tensile forces of 2600N and 2200N respectively and the static pressure of 3500N on the fixed connector, there is no obvious deformation and normal use; apply a torque of 3Nm to the key of the metal handcuffs and keep it for 30s. After the test, the key can be used normally.
