2. The lock hook can withstand a pulling force of 50KG without obvious permanent deformation, anti-vibration and anti-prying design;
3. Small size, light weight, sensitive response, simple control, water resistance, low current, energy saving and power saving;
4, low power consumption, low voltage, two AA batteries directly supply power, unlocking times up to 20,000 times;
5. Adopt special structural design, good stability, high strength vibration can be accepted, and the problem that the lock is easy to fall off is overcome;
