[0020] Compared with the prior art, the beneficial effects of the present utility model are:

[0021] (1) In this utility model, through the arrangement of structures such as a rocker, a driving gear, a mounting seat, a first transmission, a rotor rotating shaft, a generator, and a front protective shell, when the flashlight runs out of power during outdoor use, the rocker on the manual rotating handle can be used to drive the mounting seat to rotate on the driving gear, and the driving gear drives the rotor rotating shaft to rotate unidirectionally on the generator. Thus, the electric energy generated on the generator can be conveniently transmitted through a cable to the inside of the front protective shell for storage, facilitating the supply of electric energy for the lighting of the illuminating lamp. Moreover, manually generating electricity to supply electric energy to the illuminating lamp is not restricted by the usage place. Therefore, it not only increases the convenience and practicality of use, but also, by setting a charging indicator light, it can be directly seen whether the front protective shell is fully charged during hand-crank charging.

[0022] (2) In this utility model, through the arrangement of structures such as a circuit board, an illuminating lamp, a function lamp button, and an illuminating lamp button, during use, pressing the illuminating lamp button once briefly turns on the single flashlight, pressing the illuminating lamp button once again briefly turns on the dual flashlight, and pressing the illuminating lamp button one more time turns off the flashlight. Thus, it can be conveniently used in different places. At the same time, the replacement of the two types of lighting can effectively save electric energy. At the same time, pressing the function lamp button once briefly turns on the reading lamp, pressing the function lamp button once again briefly turns on the alarm lamp (red and blue flashing), and pressing the function lamp button one more time turns it off. Thus, the usage functions of the flashlight are increased. At the same time, the function lamp button and the illuminating lamp button are separately set, facilitating the user to operate intuitively.

[0023] (3) In this utility model, through the arrangement of structures such as a protective pad and a charging port, when using it at home, the charging port on the flashlight housing can be used to charge the front protective shell. During the charging process, the charging indicator light emits red light, and when the front protective shell is fully charged, the red light goes out. Thus, it can directly display whether the electric energy in the front protective shell is full.

[0024] (4) In this utility model, through the arrangement of structures such as a ratchet plate, a ratchet wheel, a positioning block, a guide rod, and a return spring, when it is tiring to use hand-crank power generation, or when it is not convenient to charge the front protective shell by hand-cranking with both hands, the rocker can be opened, and then the ratchet plate is pressed with one hand. The ratchet plate drives the ratchet wheel to rotate unidirectionally, and the ratchet wheel drives the rotor rotating shaft to rotate. Thus, the generator can also be powered. At the same time, by setting the return spring, the elastic energy of the return spring can be conveniently used to provide power for the reciprocating motion of the ratchet plate.

The rest of the features are the same as those in Embodiment 1.

[0041] The working principle is as follows: when using the flashlight at home, the front protective shell 22 can be charged using a data cable. During the charging process, the charging indicator light 35 will emit a red light. When the front protective shell 22 is fully charged, the red light of the charging indicator light 35 will go out. Then, when you need to read, you can manually short-press the function light button 25 once to turn on the reading light mode. At this time, the lighting lamp 21 emits a soft light to protect the user's eyes. In emergency use, short-press the lighting light button 26 once, one lighting lamp 21 emits light, short-press the lighting light button 26 twice, and the two lighting lamps 21 emit light at the same time, so that the brightness of the lighting lamp 21 can be adjusted according to the number of times the lighting light button 26 is pressed. When an accident occurs, short-press the function light button 25 twice to make the lighting lamp 21 emit intermittent alternating red and blue lights, thereby sounding an alarm. When used outdoors, when the front protective shell 22 of the flashlight is out of power, the handle 33 can be removed from the limit slot 3 on the flashlight housing 1. 4 is pulled out, and then the handle 33 is manually rotated. The handle 33 drives the rocker 32 to rotate, and the rocker 32 drives the mounting base 31 to rotate. The mounting base 31 drives the first transmission 36 to rotate, the first transmission 36 drives the second transmission 37 to rotate, and the second transmission 37 drives the rotor rotating shaft 38 to rotate in the generator 39, so that electrical energy can be conveniently generated. The generated electrical energy is transmitted to the front protective shell 22 through the cable for storage to be used for the next lighting lamp 21. When it is tiring to generate electricity with two hands, or it is inconvenient to use two hands to generate electricity, the ratchet plate 4 on the flashlight housing 1 can be manually squeezed, and the ratchet plate 4 is used to drive the ratchet 41 to rotate in one direction. At the same time, the ratchet plate 4 drives the return spring 46 on the guide rod 45 to be compressed, and the ratchet 41 drives the rotor rotating shaft 38 to rotate on the generator 39 to generate electricity. After loosening the ratchet plate 4, the elastic restoring force of the return spring 46 can be conveniently used to drive the ratchet plate 4 to move to the left, so that the ratchet plate 4 can be conveniently driven to return to its original position for the next use.
