X, in this state, the two claws 544 are parallel to the end face of the limit ring 530;

the hook claw 544 is shifted to swing around the rotating shaft 541, the hook 540 overcomes the elastic force of the elastic member 510 to rotate, at this time, the eccentric swing rod 542 swings towards the inside of the guide hole 12, the roller 543 arranged on the eccentric swing rod 542 presses the push plate 520 to make the push plate 520 far away from the opening side of the guide hole 12, the hook claw 544 is converted from a state parallel to the end face of the limiting ring 530 to a state perpendicular to the end face of the limiting ring 530, and at this time, the hook claw 544 is used for hooking the equipment to be maintained or the maintenance tool to provide illumination.

It should be noted that, the hook 540 and the elastic member 510 cooperate to enable the explosion-proof strong light flashlight 10 to have an automatic resetting capability, when the explosion-proof strong light flashlight 10 is taken down from the hanging position, the external force of the hook claw 544 is lost, the elastic member 510 pushes the push plate 520 to move towards the opening side of the guide hole 12, so as to drive the hook 540 to rotate reversely until the hook claw 544 abuts against the limiting ring 530, and the hanging assembly 500 returns to the initial state.

Further, the two sides of the holding boss 521 are held to apply torsion force to drive the push plate 520 to rotate, so that the boss 521 is staggered with the two rollers 543, and the elastic force provided by the elastic member 510 does not act on the hook 540 through the push plate 520, i.e. the hook 540 does not automatically recover to the initial state after the external force is removed.

For two settings of push plate 520, the following 2 different applications are applicable:

1. when the explosion-proof strong light flashlight 10 needs to be directly hung in the air to provide temporary illumination:

holding the two sides of the boss 521, applying force to rotate the push plate 520, so that the boss 521 is staggered with the two rollers 543, the elastic force applied by the elastic piece 510 to the hook 540 is relieved, the hook 544 is poked, the hook 544 is overturned to be perpendicular to the end face of the limiting ring 530, the hook 544 can be hung at a target position, and the explosion-proof strong light flashlight 10 is used as a temporary ceiling lamp.

After the explosion-proof strong light flashlight 10 is taken down, the hook 544 is shifted, the hook 544 is turned over to be attached to the end face of the limiting ring 530, then the boss 521 is held, the push plate 520 is pressed by applying force, the push plate 520 is sunk, the push plate 520 is rotated, the boss 521 faces the roller 543 again, after the boss 521 is loosened, the push plate 520 is pushed by the elastic piece 510 to reset, the boss 521 is abutted against the roller 543 again, and the hook 544 is kept in an attached state with the end face of the limiting ring 530 by providing elastic force through the elastic piece 510.

2. When the explosion-proof strong light flashlight 10 needs to be hung on a maintenance tool 20 (such as a cross wrench) to provide illumination:

referring to fig. 9, in an initial state, the two fingers 544 are moved to move the fingers 544 away from the end surface of the stop collar 530, so that the two fingers 544 are close to each other, and the long shank portion 21 of the maintenance tool passes through the fingers 544. The hook claws 544 are loosened, the hook claws 540 are reversed under the action of the elastic piece 510, the two hook claws 544 are further pushed away from each other, the hook claws 544 are propped against the long handle portion 21 in the process of approaching the end face of the limiting ring 530, and finally the long handle portion 21 is clamped between the limiting ring 530 and the hook claws 544, so that the explosion-proof strong-light flashlight 10 is fixed on a maintenance tool, and when the equipment is maintained, illumination is provided along with the fact that the maintenance tool stretches into a fault position, and the two hands of a constructor can be liberated.

The fingers 544 are again shifted to move the two fingers 544 away from the long shank portion 21, the long shank portion 21 is pulled away, the fingers 544 are released, and the fingers 544 are restored to the original position under the elastic force provided by the elastic member 510.

The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
