Preferably, a gasket 25 is disposed at the opening of the accommodation cavity 221 to further improve the sealing effect. Definitely, in other embodiments, caps in other shapes and other fixing manners may further be used to close the opening.
Preferably, a middle portion of the elastic pin 21 is projected outwards in an arced mode to form a pressing portion 211, a tail end thereof extends into an insertion cavity of the female buckle 3 and is projected on upper and lower surfaces to form a hook portion 212, and a hook position 33 adapted to the hook portion 212 is disposed in the insertion cavity. The pressing portion 211 can be exposed from a sidewall opening 34 of the insertion cavity to act as a stop, and the hook portion 212 can further be hooked with the hook position 33 to form a double-hook structure, such that the fit is tight and the connection is firm, thereby further improving the safety and reliability.
Preferably, outer surfaces of the pressing portion 211 and the guide rod 23 are each provided with a material-saving recess 4, which, on the basis of ensuring the overall structural strength, reduces the material used, the cost and the weight, and also is convenient to use.
During use, by slightly pressing the waterproof sealed cap 16, the touch switch 13 can be triggered by the elastic presser foot 15 to further switch on a light-emitting loop of the light-emitting device 1, and the LED lamps 12 emit light.
