[0037] This embodiment is intended to promote the solution to the problem in the prior art that most bicycle lights are installed by bolts. When the bicycle light is powered by batteries, when the batteries are exhausted and need to be replaced or charged, the common practice is for users to disassemble and assemble by themselves using a bolt cutter, which is inefficient. Referring to Figures 1-5, this embodiment provides a snap-on device and a bicycle lamp head for convenient connection. When the snap-on protrusion 11 and the hook portion 22 are in a misaligned state, the first connecting member 1 can be accommodated in the snap-on installation window 21. The first connecting member 1 can be rotated under the action of an external force so that the snap-on protrusion 11 is snapped into at least two hook portions 22 to form a snap-on connection state. The first connecting member 1 cannot be detached from the second connection; at the same time, when the snap-on protrusion 11 and the hook portion 22 form a snap-on connection, the first protrusion 24 is snapped into The first concave 12 or the second concave is snapped into the second protrusion to form a snap connection state. Without external force, the first connecting member 1 cannot rotate relative to the second connection. When the first connecting member 1 and the second connecting member 2 need to be detached, under the action of external force, the first connecting member 1 rotates in the snap installation window 21, so that the first protrusion 24 is snapped out of the first concave 12 or the second protrusion is snapped out of the second concave, and the snap-connecting protrusion 11 and the hook portion 22 are misaligned, and the first connecting member 1 can be taken out. The disassembly and assembly action is simple, no tools are required, and the disassembly and assembly efficiency is high.

[0038] Reference Figure 1-5 As shown, the fastening device for convenient connection includes: a first connecting member 1 and a second connecting member 2.

When the first connecting member 1 is snapped into the snap-fit ​​installation window 21, one side of the at least one first positioning protrusion 25 abuts against the bottom of the at least one first guide slope 15, and the first connecting member 1 can rotate under the action of external force, so that in the process of at least two snap-fitting protrusions 11 being snapped into the at least two inverted hooks 22, at least one first positioning protrusion 25 slides along the at least one first guide slope 15 and is snapped into the first positioning groove portion 14. Similarly, in some embodiments, at least one second positioning groove portion may be provided in the snap-fit ​​installation window 21, a second positioning protrusion portion adapted to the at least one second positioning groove portion may be provided on the surface of the first connecting member 1, and at least one second guide slope may be provided on the outer side of the second positioning groove portion, and at least one second guide slope may be a slope top on the side close to the second positioning groove portion; when the at least two snap-fit ​​protrusions 11 and the at least two inverted hooks 22 are in a misaligned state, when the first connecting member 1 is snapped into the snap-fit ​​installation window 21, one side of the second positioning protrusion portion abuts against the slope bottom of the at least one second guide slope, and the first connecting member 1 can rotate under the action of external force, so that the second positioning protrusion portion slides along the at least one second guide slope and is snapped into the second positioning groove portion during the process of the at least two snap-fit ​​protrusions 11 being snapped into the at least two inverted hooks 22.

[0044] In some embodiments, a third positioning protrusion is provided on the inner side of at least two of the inverted hooks 22, and a third positioning groove portion adapted to the third positioning protrusion is provided on the inner surface of at least two of the snap-fitting protrusions 11. The first connecting member 1 can rotate under the action of external force.

Exemplarily, the third positioning protrusion can be a semicircular protrusion, and the third positioning groove portion can be a semicircular groove.

[0045] Reference Figure 1 and 4 As shown, at least one elastic deformation portion 26 is provided in the buckle installation window 21, and at least one first positioning protrusion 25 is provided on the at least one elastic deformation portion 26; so that the at least one first positioning protrusion 25 deforms along the process of being snapped into the first positioning groove portion 14 along the at least one first guide slope 15, until the elastic deformation portion 26 is reset when the at least one first positioning protrusion 25 is snapped into the first positioning groove portion 14. It should be supplemented that the surface of the first positioning protrusion 25 is also provided with a slope 251, and the slope top is close to the outer end of the elastic deformation portion 26. In this way, during the rotation process, the slope top of the first positioning protrusion 25 can better support the elastic deformation portion 26, and the elastic deformation stroke at the outer end of the elastic deformation portion 26 is longer, which is more adaptable to the first positioning protrusion 25. At the same time, it can provide the user with a damping feedback during the rotation process, and the buckle feels better.

[0046] Reference Figure 1 and 4 As shown, a parallel connection portion 16 is provided on one side of the first connecting member 1. When at least two snap-fit ​​protrusions 11 are snapped into at least two hook portions 22 to form a snap connection, the parallel connection portion 16 contacts the surface of the second connecting member 2, and the outer contour of the parallel connection portion 16 is consistent with the outer contour of the second connecting member 2.
