The liquid bag 8331 is filled with supersaturated sodium acetate solution.

The working process of the anti-disengagement lock 8 is as follows: in the initial state, the lock tongue is retracted in the chuck without interfering the snap ring to be buckled on the chuck. When the snap ring is fastened, the snap ring passes over the lock tongue 81 and abuts on the guide surface 8211 to drive the knock pin 821 to retract, the knock pin 821 retracts to drive the seesaw lever 822 to swing, the seesaw lever 822 swings to press the lock tongue 81 to extend the lock tongue to block the direction in which the snap ring falls, and the snap ring cannot fall off the chuck 21.

When the snap ring is to be taken down, the driving head 8333 is pressed, the driving head extrudes the liquid bag 8331 and enables the elastic sheet 8332 to deform, the elastic sheet deforms to generate disturbance to the supersaturated sodium acetate solution in the liquid bag, the supersaturated sodium acetate solution is crystallized after being disturbed and releases heat to enable the temperature in the liquid bag to rise, the temperature rise enables the temperature in the liquid bag to be higher than the external temperature, the first temperature sensor and the second temperature sensor feed the detected temperature back to the controller, the controller finds that the internal temperature of the liquid bag is higher than the external temperature by more than 1 ℃ to enable the electromagnet 832 to be communicated with a power supply to be electrified, after the electromagnet is electrified, the electromagnet generates adsorption to enable the spring bolt to contract and lose the blocking effect on the snap ring, and a user can open the snap ring. When the time for connecting the electromagnet with the power supply reaches a set value, the controller disconnects the electromagnet from the power supply so that the spring bolt can extend out after the snap ring is buckled next time. In order to ensure that the supersaturated sodium acetate solution can be dissolved again after being crystallized, the invention is also provided with an electric heater for heating the liquid sac, and the liquid sac is heated once after the lock is opened once so as to ensure that the crystals of the supersaturated sodium acetate solution are dissolved again.
