     Embodiments of the technical solution of the present invention will be described in detail as below with reference to the accompanying drawings. The following embodiments are merely used for describing the technical solution of the present invention more clearly. Therefore, the embodiments are merely used as examples, but not as limitation to the protection range of the present invention. 
     It should be noted that, unless otherwise specified, the technical terms and scientific terms used in this application should be of ordinary meaning to those skilled in the field to which this invention belongs. 
     With reference to  FIG. 1  to  FIG. 3 , in an embodiment, an elastically-buckled lamp is provided, including a mounting base  1  and a lamp body  2 . The mounting base  1  includes a ceiling plate  3  mounted on a ceiling, and elastic buckles. There are more than three elastic buckles provided on a lower surface of the ceiling plate  3 . Fixed grooves adapted to the elastic buckles are provided at an upper end of the lamp body  2 . In the embodiment, the fixed grooves are arc-shaped grooves  7 , and the elastic buckles can be elastically deformed in a radial direction of the arc-shaped grooves  7  and then inserted and clamped into the arc-shaped grooves  7 . When the elastic buckles are clamped in the arc-shaped grooves  7 , the lamp body  2  can rotate relatively to the ceiling plate  3  to enable the elastic buckles to slide along the arc-shaped grooves  7 . 
     During mounting, the mounting base  1  is fixed on the ceiling, the lamp body  2  is close to the mounting base  1 , the elastic buckles are aligned to the corresponding arc-shaped grooves  7 , and the lamp body  2  is pushed to a direction of the mounting base  1 , so that the elastic buckles are clamped in the arc-shaped grooves  7 , and it is easy to mount. Moreover, after being mounted, the elastic buckles are located inside the lamp, and the lamp has good integrity and beautiful appearance. The arc-shaped grooves  7  can be circular or can be a plurality of circular arcs arranged concentrically, so that the lamp body  2  is capable of rotating relatively to the mounting base  1 . Specifically, when the lamp body  2  rotates, the elastic buckles slide in the corresponding arc-shaped grooves  7 . Therefore, it can be easy to adjust mounting angles of the lamp body  2  relative to the mounting base  1  without dismounting the lamp. 
     In other embodiments, the arc-shaped grooves can be further provided on the mounting base, the lamp body is provided with the corresponding elastic buckles, and the fixed grooves are not limited to an arc shape, but may be a linear type, a curved shape or the like. 
     In the embodiment, the ceiling plate  3  is circular, and the lamp body  2  includes a lampshade and a cover plate  6  which is detachably provided at an upper end of the lampshade. The arc-shaped grooves  7  are provided on the cover plate  6 . It should be understood that the shape of the ceiling plate  3  may also be other forms such as square, polygon and irregular shape. 
     Each of the elastic buckles includes a connecting bracket  4  and a ball  5  plunger provided on the connecting bracket  4 , the connecting bracket  4  is connected to the ceiling plate  3 , and a ball  5  of the ball  5  plunger is capable of moving in a radial direction of the circumference. The ball  5  plunger is also commonly referred to as an elastic collision bead. After being pressed, the ball  5  can retract into the plunger. When mounting the lamp body, the ball  5  collides with an opening of the arc-shaped grooves  7  and retracts into the plunger. When the ball  5  reaches a lower end of the cover plate  6 , the ball  5  extends out to clamp the elastic buckles in the arc-shaped grooves  7 . 
     Preferably, there are four elastic buckles configured to fix the lamp body  2  jointly to prevent the lamp body  2  dropping, and each two of the four elastic buckles are symmetrical around a center of the circumference. Further, the four elastic buckles are provided on a same circumference. Two arc-shaped grooves  7  located on a same circumference are provided on the cover plate  6 , and two elastic buckles are fitted within each of the arc-shaped grooves  7 . The arc-shaped grooves  7  on the cover plate  6  can be machined by stamping, and a connecting plate for connecting an inner circle and an outer circle is formed between the two arc-shaped grooves  7 , and the process is simple. 
     It should be understood that the protection scope of the present invention is not limited to four elastic buckles, and the elastic buckles can also be set as three, five or six or more according to the size and weight of the lamp body  2 . Preferably, in order to make an acting point of the elastic buckles on the lamp body  2  more uniform when the lamp body  2  is large, the elastic buckles can be arranged on a plurality of concentric circles, and at least two buckles are provided on each concentric circle so that the lamp body  2  is stressed uniformly in a radial direction. When the elastic buckles are provided on the plurality of concentric circles, correspondingly, the arc-shaped grooves  7  are also located on the plurality of concentric circles. 
     Further, a recess  8  for holding the ceiling plate  3  is also provided at an upper end of the cover plate  6 . When mounting the lamp body, the recess  8  plays a role of guiding the lamp body so that a center of the arc-shaped groove on the lamp body coincides with a central point of the plurality of elastic buckles on the mounting base. Meanwhile, when the lamp body is provided on the ceiling plate  3 , the ceiling plate  3  is located in the recess  8  so that an edge of the cover plate  6  can be fitted to the ceiling to ensure the integrity and aesthetics of the lamp. 
     Specifically, in the embodiment, the lampshade includes a lamp frame  9  and a light-transmitting plate  10  provided at a lower end of the lamp frame  9  and the cover plate  6  is provided at an upper end of the lamp frame so as to form a holding cavity in the lamp frame  9 , The light source in the holding cavity emits the illuminating light through the light-transmitting plate  10  outwardly. Preferably, the light-transmitting plate  10  is a glass plate, and the light source is an LED lamp. 
     In order to improve the lighting effect, the lampshade further includes a light guide plate  11  and a diffusion plate  12  which are provided at an upper end of the light-transmitting plate  10 , and the diffusion plate  12  is located between the light guide plate  11  and the light-transmitting plate  10 . The light guide plate  11  converts the line source emitted from the light source into an area source so that the light is even and soft, and the diffusion plate  12  realizes that the incident light is sufficiently scattered to produce an optical diffusion effect. 
     Further, a piece of reflector paper  13 , which is unidirectionally transparent to light from the top down and can reflect light emitted thereto from below, is also provided on an upper surface of the light-transmitting plate  10 , so that the upward scattered light is reflected into the light-transmitting plate  10  to improve the lighting effect. 
     In the embodiment, the circuit board is provided on a lower surface of the cover plate  6 , and a patch of the LED lamp is provided on the circuit board, and a light source plate is further provided inside the lamp frame  9 . A photomask is provided on the lower surface of the cover plate  6  to prevent light escaping from the upper end of the cover plate  6 . 
     In order to prevent the elastic buckles from being detached from the arc-shaped grooves  7  to result in that the lamp body  2  is dropped, the circuit board is provided with a wire rope which is connected to the ceiling  6  by passing through the cover plate  6  so as to prevent the lamp body  2  from dropping when an emergency occurs, thus resulting in potential safety hazard. 
     In other embodiments, the elastic buckle can also be a snap bulge which is formed by an elastic sheet and can be elastically deformed in a radial direction of the arc-shaped groove. One end of the snap bulge facing the lamp is wedge-shaped, and a bevel transition is formed between upper and lower ends of the snap bulge, so that the snap bulge can be inserted and clamped into the arc-shaped groove. 
     It should be understood that, in other embodiments, the mounting base may also be a base fixed to a position such as a wall or a cabinet, thereby forming lamps of different type.
