[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example: Figures 1-8As shown, this reliable multi-angle adjustable spotlight includes an outer shell 1, an inner shell 2, and a light source 3. The outer shell 1 has an adjustment cavity 101. The inner shell 2 is equipped with the light source 3 and is rotatably connected to the adjustment cavity 101. The inner shell 2 can rotate relative to the outer shell 1 with its geometric center as the axis to adjust the light emission angle of the light source 3. The cavity wall of the adjustment cavity 101 is provided with a buffer groove 102, and a buffer strip 4 is provided in the buffer groove 102. The buffer strip 4 at least partially abuts against the outer wall of the inner shell 2 and is squeezed and deformed to buffer the light when the inner shell 2 rotates. The outer shell 1 and the inner shell 2 are made of metal, and the buffer strip 4 is made of deformable plastic. This embodiment provides a reliable multi-angle adjustable cylindrical spotlight to solve the problem of complex internal structures in existing spotlights, which achieve relative rotation between the inner and outer shells through an adjusting rod on the inner shell and an adjusting groove on the outer shell. The solution is achieved by configuring an adjusting cavity 101 on the outer shell 1, with the inner shell 2 housed within the cavity 101 and able to rotate relative to the outer shell 1 with its geometric center as the axis to adjust the light emission angle of the light source 3. This rotation adjustment structure is compact and simple, resulting in a reliable multi-angle adjustable cylindrical spotlight with a simple internal structure and a wide range of rotation for the inner shell 2. Furthermore, by configuring a buffer groove 102 on the wall of the adjusting cavity 101, and a buffer strip 4 within the buffer groove 102 that at least partially abuts against the outer wall of the inner shell 2 and is subjected to deformation and cushioning during rotation of the inner shell 2, the inner shell 2 avoids hard contact with the outer shell 1 during rotation. The deformation and cushioning effect of the buffer strip 4 ensures smooth rotation of the inner shell 2 and extends the lifespan of the spotlight.

[0028] In this embodiment of the invention, the adjustment cavity 101 opens at one axial end of the outer shell 1, the light source 3 emits light through the opening of the adjustment cavity 101, and the inner shell 2 adjusts the angle between the light source 3 and the axis of the outer shell 1 when it rotates relative to the outer shell 1. The buffer groove 102 extends around the axis of the outer shell 1. This arrangement, by configuring the adjustment cavity 101 to open at one axial end of the outer shell 1, and adjusting the angle between the light source 3 and the axis of the outer shell 1 when the inner shell 2 rotates relative to the outer shell 1, ensures a reasonable and compact assembly of the inner shell 2 and the outer shell 1. Furthermore, by configuring the buffer groove 102 to extend around the axis of the outer shell 1, the buffer strip 4 provides good buffering and damping effects, allowing the inner shell 2 to rotate smoothly.

[0029] In this embodiment of the invention, the inner shell 2 is hemispherical and can rotate relative to the outer shell 1 with its center as the axis. By configuring the inner shell 2 as hemispherical and allowing it to rotate relative to the outer shell 1 with its center as the axis, the inner shell 2 and the outer shell 1 are reasonably and compactly assembled and rotate smoothly.

[0030] In other embodiments, the inner shell 2 may also be configured as a sphere.

[0031] In this embodiment of the invention, there are two buffer grooves 102, which are arranged opposite to each other in the axial direction of the outer shell 1. More preferably, one buffer groove 102 is adjacent to the opening of the adjustment cavity 101, and the other buffer groove 102 is adjacent to the end of the inner shell 2 away from the opening of the adjustment cavity 101. By configuring two buffer grooves 102 and arranging them opposite to each other in the axial direction of the outer shell 1, the inner shell 2 rotates smoothly, and the buffer strip 4 has a good buffering and damping effect.

[0032] In this embodiment of the invention, the outer casing 1 includes a front outer casing 103 and a rear outer casing 104 arranged sequentially along its axial direction. The front outer casing 103 and the rear outer casing 104 are detachably and fixedly connected to form an adjustment cavity 101. The front outer casing 103 and the rear outer casing 104 cooperate to confine the inner casing 2 within the adjustment cavity 101. The front outer casing 103 and the rear outer casing 104 can be connected by, but are not limited to, threaded connections or snap-fit ​​connections. This configuration, by setting the outer casing 1 with a detachably and fixedly connected front outer casing 103 and rear outer casing 104, which together form the adjustment cavity 101 and confine the inner casing 2 within it, makes the assembly and disassembly of the outer casing 1 quick and easy, and ensures stable assembly with the inner casing 2.

[0033] In this embodiment of the invention, one buffer groove 102 is formed on the front outer shell 103, and the other buffer groove 102 is formed on the rear outer shell 104. The above arrangement, by distributing the two buffer grooves 102 on the front outer shell 103 and the rear outer shell 104 respectively, makes the two buffer grooves 102 reasonably distributed and easy to process.

[0034] In this embodiment of the invention, the light source component 3 has a retaining strip 301 extending circumferentially therearound, and the inner shell 2 includes a front inner shell 201 and a rear inner shell 202 arranged sequentially in the axial direction of the outer shell 1. The front inner shell 201 and the rear inner shell 202 are detachably and fixedly connected to form a slot 203 for inserting the retaining strip 301. The front inner shell 201 and the rear inner shell 202 can be connected, but are not limited to, by threaded connection or snap-fit ​​connection. By configuring the inner shell 2 as a front inner shell 201 and a rear inner shell 202, and configuring the light source component 3 with a retaining strip 301 extending circumferentially therearound, and the detachable and fixedly connected front inner shell 201 and the rear inner shell 202 to form a slot 203 for inserting the retaining strip 301, the inner shell 2 is quick and easy to assemble and disassemble, and is stably assembled with the light source component 3.
