[0062] This embodiment uses a locking mechanism and a magnetic attraction mechanism between the flashlight body 100 and the protective shell 200 to achieve reliable assembly and convenient disassembly, thereby increasing the service life and reliability of the flashlight.

[0063] In another embodiment, if Figure 3 The magnetic attraction mechanism between the flashlight body 100 and the protective shell 200 can be designed as a push-card. Specifically, a plurality of second magnetic elements 251 are arranged on the protective shell 200 along its axial direction at intervals, and each second magnetic element 251 provides magnetic attraction resistance between the flashlight body 100 and the first magnetic element when the flashlight body 100 is removed from the protective shell 200.

[0064] With such a design, the flashlight body 100 can be manually pushed to move in sequence between the positions corresponding to the plurality of second magnetic elements 251, thereby forming a card-pushing effect, allowing the user to exercise finger flexibility and increase the fun of use when replacing the protective shell 200 or using it normally.

[0065] Preferably, the second magnetic member 251 is a magnetic block or a magnetic ring matching the size of the protective shell 200 or a plurality of magnetic blocks arranged at intervals along the circumference of the protective shell 200; more preferably, the intervals between adjacent second magnetic members 251 are equal.

[0071] In this embodiment, the locking mechanism is engaged by cooperating with the latch 242 and the limiting rib 241 through an abutment surface that is inclined relative to the slide groove of the protective shell 200. When the locking member 140 is locked into place, the friction between the abutment surface and the limiting rib 241 can keep the protective shell 200 stable. The clamping surface formed by the upward bending of the back side of the locking member 140 enhances the friction between the abutment surface and the limiting rib 241.

[0072] In specific operation, it is only necessary to push the locking member 140 forward. When the applied pushing force is sufficient to overcome the friction between the abutting surface and the limiting rib 241 , the distal end of the locking member 140 disengages from the locking port 242 on the protective shell 200 , and the locking mechanism is unlocked.

The card-pushing mechanism has a movable shell 300 slidably arranged on the outside of the protective shell 200 and a third magnetic member 310 arranged in the movable shell 300. There is magnetic attraction between the third magnetic member 310 and the second magnetic member 251. At this time, there are multiple second magnetic members 251 arranged at intervals along the axis direction of the protective shell 200, and each second magnetic member 251 provides magnetic attraction resistance between the flashlight body 100 and the first magnetic member when it is out of the protective shell 200. For details, please refer to the above embodiment.

[0075] Specifically, limit buckles 252 are respectively provided on both sides of the plurality of second magnetic components 251 along the axial direction on the outer side of the protective shell 200, and grooves 320 are provided on the inner side of the movable shell 300 to match the limit buckles 252, which are used to prevent the movable shell 300 from detaching from the protective shell 200 during the card pushing operation through the magnetic force between the second magnetic components 251 and the third magnetic components 310, so that the implementation effect of the card pushing mechanism is more stable and reliable.
